You can read our HPE6-A90 free dumps below to verify our latest materials:

1. A NOC Operations Engineer is troubleshooting an AOS-10 Gateway cluster that is failing to form. Both gateways are physically patched into an AOS-CX 8325 core switch. Central reports the cluster status as "Down/Isolated".

The engineer investigates the wired underlay configuration connecting the two gateway nodes:

[AOS-CX 8325 Switch - Interface Status]

Interface 1/1/1 (Connected to Gateway Node 1)

VLAN Mode: Trunk

VLAN Trunk Allowed: 10, 20, 30

Native VLAN: 10

Interface 1/1/2 (Connected to Gateway Node 2)

VLAN Mode: Trunk

VLAN Trunk Allowed: 10, 20, 40

Native VLAN: 20

Which TWO configuration issues on the underlay switch will prevent these AOS-10 Gateways from forming a valid, fully functional Layer 2 cluster? (Choose 2.)

The gateways are attempting to negotiate dynamic LACP with the core switch, a protocol that is explicitly blocked when native VLANs differ across a chassis.

The native (untagged) management VLANs mismatch (VLAN 10 vs VLAN 20), breaking the fundamental Layer 2 cluster heartbeat and discovery process between the nodes.

Layer 2 clustering requires Spanning Tree Protocol (STP) to be completely disabled on the switch ports to allow the proprietary multicast heartbeat frames to pass unhindered.

The allowed trunk VLANs are inconsistent (missing VLAN 30 on port 1/1/2, and missing VLAN 40 on port 1/1/1), which will cause asymmetric dropping of client data plane traffic during a failover event.

The switch ports are configured as 802.1Q trunks, whereas AOS-10 Gateways strictly require standard access ports to successfully negotiate their cluster virtual MAC addresses.

2. A Network Compliance Auditor relies heavily on the Central performance dashboards to evaluate campus capacity planning. However, they consistently misjudge actual wireless utilization, leading to unexpected saturation events during end-of-month reporting periods.

Which TWO actions represent operational anti-patterns when utilizing Central's health and performance dashboards for long-term capacity planning? (Choose 2.)

Utilizing the API Gateway to programmatically export weekly performance metrics into a dedicated long-term data warehouse.

Reviewing the RF Health dashboard to identify areas with chronic co-channel interference before deciding to purchase and deploy additional access points.

Correlating the "Data Usage" metrics with the "Client Count" metrics to differentiate between high-density idle devices and high-bandwidth active clients.

Disabling the periodic telemetry streaming from the APs to Central in order to "save WAN bandwidth," thereby starving the dashboards of granular data.

Focusing exclusively on instantaneous, real-time client counts without adjusting the time-series filter to analyze peak historical trends over a 30-day period.

3. A Campus IT Manager wants to quickly identify which specific building (Site) in a 50-building campus has experienced the highest concentration of wireless client connection failures over the last 24 hours.

Which workflow within the HPE Aruba Networking Central UI represents the most direct method to obtain this specific operational intelligence?

Download the raw JSON audit logs from the GreenLake platform and utilize a custom Python script to parse MAC authentication failures.

Navigate to the Global Network Health dashboard, select the 'Clients' tab, and easily review the 'Connectivity' metrics by Site.

Access the local WebUI of each individual AOS-10 gateway device and manually check the datapath tables for dropped user sessions.

Create a new NetConductor global role policy that specifically tags failing clients to force a packet capture on the core switches.

4. A Network Architect is reviewing a proposed template design for a large deployment of AOS-CX 6200 switches. The junior engineer who drafted the proposal intended to use the 6200s as high-performance aggregation nodes for a new EVPN-VXLAN campus overlay.

Device Type: AOS-CX 6200F 48G

Class 4 PoE 4SFP+ 370W

Proposed Configuration

Features:

1. EVPN-VXLAN Route Reflector (BGP

RR)

2. VSX Active-Active Default

Gateway (Active-Gateway)

3. Dynamic Segmentation

(User-Based

Tunneling)

4. OSPF Underlay Routing

(Point-to-Point)

5. MAC Authentication with

ClearPass

VSAs

Which TWO proposed features represent absolute hardware or software anti-patterns for the AOS-CX 6200 series platform and must be removed from the design? (Choose 2.)

Attempting to use the 6200 series to execute Dynamic Segmentation (User-Based Tunneling), as this requires a dedicated hardware GRE module only found on the 6400 chassis.

Configuring the 6200 series to act as an EVPN-VXLAN Route Reflector (BGP RR), a role that exceeds the platform's routing table capacity and intended architectural placement.

Integrating MAC Authentication with ClearPass VSAs, which is an advanced identity feature exclusively supported on the AOS-10 Gateway clusters.

Designing the aggregation layer to use Virtual Switching Extension (VSX) Active-Active Gateways, as the 6200 series strictly supports Virtual Switching Framework (VSF) instead.

Utilizing OSPF Underlay Routing for point-to-point links, because the 6200 series only supports static routing and basic RIPv2 protocols.

5. What is the primary purpose of enabling IGMP Snooping on an AOS-CX switch VLAN within a campus network?

To actively prune IPv4 multicast traffic so it is only forwarded to physical ports with explicitly interested receivers.

To prevent IPv6 multicast traffic from flooding the Layer 2 broadcast domain by utilizing MLD snooping features.

To dynamically establish point-to-multipoint IPsec tunnels across the campus core for secure video delivery.

To translate Layer 2 broadcast frames into unicast frames to reduce overall airtime utilization on the wireless network.

6. A Campus IT Manager is drafting a proposal to deploy Dynamic Segmentation across a university campus. They plan to use User-Based Tunneling (UBT) to secure legacy devices.

Which TWO statements represent severe anti-patterns or critical design flaws when planning a UBT deployment? (Choose 2.)

Defining a primary gateway cluster IP for the UBT zone and configuring a secondary cluster IP to ensure high availability for the tunnels.

Ensuring the UBT underlay network accommodates jumbo frames (MTU 9000) to safely account for the GRE and IPsec encapsulation overhead.

Tunneling high-bandwidth, trusted server-to-server traffic from the data center edge switches to the campus gateways for stateful firewall inspection.

Utilizing UBT to isolate legacy, unpatchable medical devices that only support MAC authentication and cannot run 802.1X supplicants.

Configuring a "fail-open" local VLAN role for highly untrusted IoT devices to ensure they maintain internet access if the UBT connection to the gateway cluster goes down.

7. A Network Administrator is designing a Microbranch deployment for a pop-up retail kiosk. The kiosk requires secure routing to the corporate datacenter VPNC. The deployment location only has access to a public Wi-Fi network and a 5G cellular modem.

Which uplink design must the administrator use for the Microbranch AP running AOS 10.3?

For this Microbranch deployment in AOS 10.3, utilize the cellular modem for guest traffic and configure the public Wi-Fi uplink solely for the IPsec tunnel to the corporate VPN

Deploy an external wireless bridge to convert public Wi-Fi to Ethernet since Microbranch supports only Ethernet and cellular uplinks.

Configure the Microbranch AP to use the public Wi-Fi network as the primary uplink and the cellular modem as a backup.

Configure both Wi-Fi and Cellular uplinks on the Microbranch AP within an active-active load-balancing group in AOS 10.3 to maximize aggregate bandwidth to the corporate datacenter.

8. A Network Architect is designing a high-density AOS-10 wireless network using ultra-tri-band APs. To support multi-gigabit throughput, the APs are connected to AOS-CX access switches using two physical Ethernet uplinks configured for Link Aggregation (LACP).

[AOS-CX Switch - Port Configuration]

interface lag 10 multi-chassis

no shutdown

no routing

vlan trunk native 10

vlan trunk allowed 10,20,30

lacp mode active

Which THREE statements accurately describe the operational behavior and tunnel orchestration dynamics of an AOS-10 AP utilizing LACP uplinks? (Select all that apply.)

The AP will load-balance the tunneled IPsec traffic across both physical links by utilizing a proprietary payload-decapsulation hashing algorithm to bypass the switch's native LAG hashing.

Central requires the administrator to manually define the MAC address of the upstream switch's LAG interface within the AP Group's uplink configuration to permit tunnel establishment.

The AP utilizes the aggregated logical link to establish its single management IP and subsequently builds its high-throughput IPsec data tunnels to the Gateway cluster over this bonded connection.

If LACP negotiation fails (e.g., switch misconfiguration), the AOS-10 AP will inherently fall back to an active/standby uplink model to ensure management connectivity to Central is not completely lost.

The AOS-10 AP automatically negotiates LACP using standard 802.3ad protocols, meaning the upstream AOS-CX switch must have the two corresponding ports configured as an active LA

9. An enterprise deploys AOS-10 Campus APs that tunnel traffic to a centralized Gateway cluster. The campus network enforces strict Zero Trust using 802.1X port-based security on all wired AOS-CX access switches. The APs must cryptographically authenticate to the switch port before gaining uplink access to the network.

[AOS-CX Switch - Port Access Configuration]

interface 1/1/5

port-access dot1x enable

port-access role AP_UPLINK

vlan access 10

Which THREE statements accurately describe the interaction between the AP's wired uplink authentication and the subsequent AOS-10 tunnel orchestration process? (Select all that apply.)

If the AP fails 802.1X authentication at the switch port, it immediately reverts to Bridge mode forwarding to ensure localized IoT clients can still access the internet via the restricted fallback VLA

After the AP checks in, the Central Tunnel Orchestrator service utilizes the AP's active cloud connection to securely push the routing tables and cryptographic material needed to build the data plane tunnels to the Gateway cluster.

Once the switch port authorizes the AP and places it on the management VLAN (VLAN 10), the AP requests a DHCP address and establishes a secure WebSocket connection to HPE Aruba Networking Central.

The upstream AOS-CX switch must dynamically push the IPsec tunnel destination IP addresses directly to the AP via a proprietary RADIUS Vendor-Specific Attribute (VSA) upon successful 802.1X authentication.

The AOS-10 AP acts as an 802.1X supplicant, utilizing its factory-installed Trusted Platform Module (TPM) certificate or a Central-provisioned certificate to authenticate against the wired switch port.

10. Which IEEE 802.11 amendment specifically allows an AOS-10 Campus AP to actively provide connecting clients with a "Neighbor Report," assisting the client device in making faster, more informed roaming decisions without needing to actively scan all RF channels?

802.11k (Radio Resource Measurement)

802.11w (Protected Management Frames)

802.11v (BSS Transition Management)

802.11r (Fast BSS Transition)

11. A Campus IT Manager is evaluating the routing architecture for a new EVPN-VXLAN overlay. They must choose between implementing a Centralized L3 Gateway design (routing at the Border/Spine) and a Distributed L3 Gateway design (Anycast gateway at the Leaf/Edge).

Which THREE statements accurately evaluate the trade-offs and operational mechanics of these two architectural models? (Select all that apply.)

Implementing a Distributed L3 Gateway requires the access layer switches (e.g., AOS-CX 6300) to support advanced routing capabilities and possess sufficient hardware resources to maintain the synchronized Anycast MAC/IP tables.

A Distributed L3 Gateway design (Anycast Gateway) optimizes East-West traffic by routing packets at the ingress edge switch, reducing latency and avoiding traffic hairpinning through the core.

The Distributed L3 Gateway model dictates that all external Internet-bound traffic must bypass the EVPN-VXLAN overlay entirely and route natively over the OSPF underlay.

A Centralized L3 Gateway design inherently requires embedded Data Processing Units (DPUs) on all edge access switches to offload the massive MAC address learning tables.

A Centralized L3 Gateway design simplifies the configuration of the access switches, as they only perform Layer 2 VXLAN encapsulation and rely entirely on the Border/Spine nodes for inter-VLAN routing.

12. A Security Operations Analyst is integrating AOS-10 Campus APs (operating strictly in Bridge Mode) with an EVPN-VXLAN campus fabric managed by Central NetConductor.

The APs are broadcasting a Corporate SSID mapped to local VLAN 100. Wireless clients authenticate via 802.1X, and ClearPass Policy Manager returns NetConductor global roles dynamically.

[NetConductor Policy]

Role 'Finance_User' -> GPID 505

Role 'HR_User' -> GPID 606

Which THREE statements correctly describe how the Campus AP persona handles the bridge mode datapath and NetConductor role enforcement within this specific fabric architecture? (Select all that apply.)

The downstream AOS-CX access switch receives the bridged, GPID-tagged Ethernet frame, encapsulates it into the EVPN-VXLAN overlay, and forwards it across the campus while preserving the identity context.

Bridge mode inherently strips all role-based metadata from the 802.11 frames, requiring the downstream AOS-CX switch to perform a secondary MAC authentication to re-apply the NetConductor roles.

The Campus AP acts as the authenticator, securely communicates with ClearPass, downloads the NetConductor Role assigned to the user, and translates this role into its numeric Group Policy Identifier (GPID).

Because the AP is in Bridge mode and participating in the fabric, it must embed the numerical GPID directly into the bridged 802.3 Ethernet frame before dropping it onto the local switch port (VLAN 100).

The Campus AP encapsulates the bridged traffic in an IPsec tunnel and forwards it directly to the Central NetConductor Orchestrator in the cloud to receive the appropriate GPID tag.

13. A NOC Operations Engineer is troubleshooting an EVPN-VXLAN fabric where clients connected to an AOS-CX 6300 fabric edge switch cannot reach resources in the data center. The OSPF underlay routing is confirmed healthy, but the BGP EVPN control plane is failing to establish.

[AOS-CX 6300 - Edge Node CLI Output]

Switch# show bgp l2vpn evpn summary

VRF : default

BGP Summary

Local AS : 65001 BGP Router ID : 10.254.1.10

10.254.0.2 65001 0 0 00:00:00 Active

Based on the provided diagnostic output, which TWO underlying misconfigurations are preventing the EVPN control plane from establishing? (Choose 2.)

The EVPN-VXLAN Network Identifiers (VNIs) have not been properly mapped to the local VLANs on the edge switch.

The AOS-CX 6300 switch requires an Advanced subscription license to activate the OSPF underlay routing process, which has expired.

The edge switch has dynamically learned too many MAC addresses, exhausting the hardware CAM table and causing the BGP process to crash.

The Loopback interfaces used for the BGP EVPN peerings (10.254.0.1, 10.254.0.2) are not being correctly advertised into the OSPF underlay.

There is a BGP Autonomous System Number (ASN) mismatch or a strict firewall filter blocking TCP port 179 between the leaf and the Route Reflector.

14. A Central Platform Administrator is automating the migration of a massive enterprise network. They must dynamically assign 5,000 newly onboarded AOS-CX switches into specific Configuration Groups based on their role, and apply appropriate Device Tags for monitoring.

The enterprise utilizes a multi-tenant architecture with two distinct GreenLake Workspaces: Workspace_Corp and Workspace_Retail.

The administrator executes a bulk API script to apply the tag [Status: Pre-Prod] and assign the switches to the Grp_Access_Baseline Configuration Group.

API Response Snippet:

{

"success": 2450,

"failed": 2550,

"errors": [

{

"device_mac": "00:1A:2B:3C:4D:5E",

"error": "Group Grp_Access_Baseline not found in current

context."

},

{

"device_mac": "00:1A:2B:3C:4D:5F",

"error": "Tag assignment failed: Device belongs to a different

tenant workspace."

}

]

}

Based on the interaction between Workspace boundaries, Configuration Groups, and Tagging mechanics, which THREE statements explain these API failures? (Select all that apply.)

Devices must be fully licensed and assigned to a Configuration Group BEFORE any Device Tags can be applied to them via the Central AP

Configuration Groups are strictly bounded within a single Workspace. A group named Grp_Access_Baseline created in Workspace_Corp does not exist and cannot be referenced by devices in Workspace_Retail.

Device Tags are global entities within GreenLake; however, the API token used was scoped strictly to Workspace_Corp, preventing tag application on devices residing in Workspace_Retail.

True multi-tenant automation requires executing the group assignment and tagging API calls independently against the specific API Gateway endpoint corresponding to each distinct Workspace.

The API script failed because it attempted to assign a tag ([Status: Pre-Prod]) that contains special characters (brackets and hyphens), which violates Central's tag naming conventions.

15. What is a key architectural distinction between the AOS-CX 6300 and 6400 series switches when planning for access layer and distribution layer high availability?

The 6400 natively supports Cloud Authentication services via Aruba Central, while the 6300 requires a dedicated ClearPass Policy Manager appliance for identity management functions.

The 6300 uses VSF stacking for high availability; the 6400 is a modular chassis with redundant Management Modules (MMs) providing internal high availability.

Both switch series require centralized Aruba Mobility Controllers (MCs) to manage and synchronize their redundant control plane instances across the network.

The 6300 series relies on VSX for core routing tasks, whereas the 6400 series utilizes VSF to handle edge access layer connectivity requirements.

16. What is a fundamental requirement for a factory-default AOS-CX switch to successfully complete the Zero Touch Provisioning (ZTP) process and receive its initial configuration from HPE Aruba Networking Central?

The switch must be manually added to a designated Configuration Group via the local serial console CLI before booting.

The switch must dynamically receive a valid IP address and DNS server information via DHCP on an active uplink interface.

The switch must have a statically assigned IP address on its out-of-band management (OOBM) port before connecting to the network.

The switch must be pre-staged with a custom Python script to initiate the outbound HTTPS connection to the cloud portal.

17. A NOC Operations Engineer is troubleshooting a persistent roaming issue in an AOS-10 environment. Medical VoIP clients are dropping calls specifically when moving between Campus-AP-01 and Campus-AP-02, both managed by Branch-GW-01.

The engineer uses SSH to access both the Gateway and the AP directly to deeply inspect the state.

Review the CLI output below:

Reason Code: 6 (Class 2 frame received from nonauthenticated STA)

To effectively fuse CLI execution skills with roaming diagnostics, which THREE statements represent correct analytical approaches based on this methodology? (Select all that apply.)

Utilizing show ap remote debug mgmt-frames on the AP CLI is critical for analyzing the raw 802.11 authentication and association frames exchanged during the roaming event.

The correct diagnostic step to resolve the Reason Code 6 error is to use the CLI to completely disable 802.11k/v/r protocols on the VoIP SSI

Executing show datapath user on the gateway CLI is necessary to verify if the client's tunnel and forwarding state correctly updated after roaming to the new A

The engineer could optionally utilize the WebUI Remote Console to run show ap debug client-table to inspect the client's current association state and RSSI values without needing an SSH client.

The engineer should run clear arp on the core switch via Central to flush the gateway's client cache, forcing a complete network-wide re-authentication.

18. In the context of HPE Aruba Networking Central, what is the foundational architectural principle of NetConductor global client roles when compared to traditional network segmentation?

Global client roles decouple security policy from the underlying network topology by carrying role context directly within the data plane encapsulation.

NetConductor requires all client traffic to be routed through a centralized physical firewall appliance to apply role-based access control policies.

Global client roles permanently bind a client's MAC address to a specific physical switch port to enforce strict hardware-level segmentation boundaries.

The architecture relies on configuring static, localized Access Control Lists (ACLs) on every individual access switch to match specific IP subnets.

19. A NOC Operations Engineer is deploying a new building with AOS-CX 6200 access switches and AOS-10 Campus APs. The design mandates a "Mixed Forwarding" approach to handle different device classes.

[AOS-10 AP Configuration]

SSID: Corp_Laptops -> Forwarding Mode: Tunnel

SSID: IoT_Sensors -> Forwarding Mode: Bridge -> VLAN 50

[AOS-CX 6200 Switch Configuration]

interface 1/1/10

description

UPLINK-TO-CAMPUS-AP-01

[Pending Configuration]

To ensure both SSIDs function correctly, which THREE statements describe the mandatory VLAN and interface configurations required on the connected AOS-CX access switch port? (Select all that apply.)

The switch port must explicitly allow and tag the destination VLAN for the Corp_Laptops SSID, as tunnel mode relies on the local switch to route the corporate traffic.

The switch port must be configured as a trunk port because it must natively carry the tagged traffic for the bridged IoT VLAN (VLAN 50).

The switch port must not block UDP port 4500, as this port is strictly required for the AP to encapsulate the tunnel mode data plane traffic and send it to the AOS-10 Gateway cluster.

The switch port must allow the AP's management VLAN to pass (typically untagged/native) so the AP can obtain an IP address, reach Central, and build the IPsec tunnels for the Corp_Laptops SSI

The switch port must be configured as a standard access port assigned exclusively to the management VLAN to allow the AP to build its control plane tunnel.

20. What is the primary method to securely execute CLI commands on an AOS-10 Gateway managed by Central without requiring direct network reachability to the gateway's local management IP address?

By deploying a local Mobility Master on-premises to proxy the terminal connection back to the cloud.

By utilizing the Remote Console feature integrated natively within the HPE Aruba Networking Central WebU

By connecting a physical console cable to the gateway and using dedicated terminal emulation software.

By establishing a direct SSH session using port 22 to the gateway's public WAN interface over the internet.

21. What is a fundamental architectural restriction regarding the predefined, factory-default administrative roles (such as 'admin', 'network-ops', and 'readonly') within HPE Aruba Networking Central?

They are completely immutable; administrators cannot modify their specific application-level permissions and must create custom roles to achieve granular access control.

They automatically inherit the OAuth2 permission scopes that are assigned to the highest-privileged user who is currently logged into the specific tenant workspace.

Within HPE Aruba Networking Central, these predefined roles mandate the use of physical hardware tokens (such as YubiKey or similar FIDO2-compliant devices) for multi-factor authentication (MFA) as a prerequisite before assignment to any user account in the tenant workspace.

These roles are strictly designated for managing wireless infrastructure components exclusively (including Aruba APs, mobility controllers, and gateways) and cannot be utilized to administer AOS-CX wired switching environments, campus fabrics, or any wired network elements.

22. A Network Architect is reviewing the deployment of AOS-10 Tri-band APs. The APs require 802.3bt (Class 6 - 60W) PoE to fully power all three radios, the USB port, and the secondary Ethernet port.

However, the legacy AOS-CX 6200 access switches in the building only provide 802.3at (Class 4 - 30W) PoE+.

The architect reviews the switch port and Central status for one of these APs:

[AOS-CX Switch]

Interface 1/1/10

Power Allocated: 25.5W (Class 4)

LLDP-MED Power Negotiation: Successful

[Central AP Health Status]

Status: Power Restricted

Operational State: 2.4GHz (2x2), 5GHz (2x2), 6GHz (Disabled)

Based on the provided data, which TWO statements accurately describe how the AOS-10 AP and AirMatch interact with this hardware power constraint? (Choose 2.)

The AOS-CX switch enforces a localized Control Plane Policing (CoPP) policy to drop the AP's management traffic until a valid Class 6 midspan injector is physically installed.

The AP leverages Intelligent Power Monitoring (IPM) to dynamically disable specific hardware features (like the 6 GHz radio) according to a prioritized list, ensuring the core functionality survives within the 30W budget.

AirMatch automatically detects the AP's reduced power state and adjusts the overall campus RF plan, knowing that the specific AP cannot provide 6 GHz coverage or maximum EIRP on the remaining bands.

The AP automatically transitions its remaining 2.4 GHz and 5 GHz radios into a localized Bridge mode to offset the CPU power required for IPsec encapsulation.

AirMatch overrides the switch's LLDP-MED negotiation, forcing the port to draw 60W, which risks triggering a hardware overcurrent shutdown on the legacy AOS-CX switch.

23. A NOC Operations Engineer is troubleshooting a datacenter redundancy issue. Remote Microbranch APs are configured to build primary IPsec tunnels to VPNC-Primary and secondary tunnels to VPNC-Standby.

When VPNC-Primary was rebooted for scheduled maintenance, the Microbranch APs failed to establish tunnels to VPNC-Standby, causing a complete site outage.

[Microbranch AP Datapath Log]

10:02:15 IKE Phase 1: Initiating main mode to VPNC-Primary (198.51.100.10)

10:02:20 IKE Phase 1: Timeout connecting to VPNC-Primary

10:02:20 IKE Phase 1: Initiating main mode to VPNC-Standby (203.0.113.50)

10:02:21 IKE Phase 1: VPNC-Standby rejected proposal. MM_NO_STATE

10:02:21 ERROR: IPsec Tunnel to VPNC-Standby failed to establish.

Based on the provided log data, which TWO configurations are the most likely causes of this failover failure? (Choose 2.)

Microbranch APs inherently only support a single, non-redundant IPsec tunnel to a single VPNC to conserve memory.

VPNC-Standby has a mismatched IPsec Pre-Shared Key (PSK) or certificate trust chain compared to the Microbranch APs' provisioning profiles.

VPNC-Standby is missing the correct routing configuration to advertise the datacenter subnets to the remote Microbranch APs.

The IKE/IPsec crypto maps on the VPNC-Standby do not match the encryption algorithms proposed by the remote Microbranch A

The Microbranch APs lack the Advanced subscription license required to support multiple concurrent IPsec tunnel destinations.

24. A NOC Operations Engineer is troubleshooting an OSPF underlay network in a newly deployed Leaf-Spine campus fabric. The physical fiber links between Leaf-1 and Spine-1 are online, but the OSPF adjacency is failing to establish.

The engineer checks the AOS-CX CLI on Leaf-1 and reviews the OSPF neighbor state:

Leaf-1# show ip ospf neighbor

OSPF Process ID 1

======================================================================

Neighbor ID Pri State Dead Time Address Interface

10.254.0.1 1 EXSTART/DROther 00:00:32 10.1.1.1 1/1/49

10.254.0.2 1 FULL/BDR 00:00:36 10.1.1.5 1/1/50

Based on this specific OSPF neighbor state output, which TWO issues are the most likely causes of the failure between Leaf-1 and Spine-1 (10.254.0.1)? (Choose 2.)

The OSPF Hello or Dead timers are mismatched between the Leaf-1 interface and the Spine-1 interface.

One switch interface is configured as an OSPF broadcast network type, while the other is mistakenly configured as point-to-point.

The OSPF router IDs on both Leaf-1 and Spine-1 have been accidentally configured with the exact same IP address.

There is an IP Maximum Transmission Unit (MTU) mismatch configured on the point-to-point interfaces connecting the two switches.

The physical fiber optic cable between the switches is experiencing unidirectional link failure, dropping all hellos.

25. Following a recent campus renovation, a NOC Operations Engineer investigates reports of severe wireless instability in a modernized open-office space. The new AOS-10 Campus APs were mounted directly on the exposed 15-foot ceilings, flush against large, metallic HVAC ductwork for aesthetic reasons.

The engineer extracts the following system logs from an affected AP:

Sep 14 09:12:05 ap-system[312]: <WARN> High PHY retry rate (45%) detected on radio 0

Sep 14 09:15:10 ap-rfm[441]: <ERROR> Channel utilization exceeded 80% threshold

Sep 14 09:18:22 ap-system[312]: <INFO> Client a1:b2:c3:d4:e5:f6 disconnected due to excessive unacknowledged frames

Based on the physical deployment constraints and the diagnostic logs, which TWO issues are the primary drivers of this network degradation? (Choose 2.)

The metallic HVAC ductwork, owing to its high conductivity, induces severe multipath reflection and RF shadowing across operational frequency bands, directly destroying signal integrity and causing the documented 45% frame retry rate.

AOS-10 firmware inherently disables MIMO processing for access points mounted above 12 feet specifically to conserve PoE power drawn from the access switch.

The elevated PHY retry rate stems from upstream gateway cluster dropping IPsec tunnel packets, compelling the AP to retransmit payload repeatedly over the wireless medium.

The APs were mistakenly configured with WPA2-Personal security protocol instead of WPA3, resulting in wireless driver rejection of legacy client connections due to authentication protocol incompatibilities.

High ceiling mounting of APs in reflective environments scatters the omnidirectional RF signal, expanding coverage to include co-channel interference from neighboring floors and driving channel utilization beyond the 80% threshold.

26. A Network Solutions Consultant is designing an extensive monitoring dashboard that continuously aggregates client telemetry from HPE Aruba Networking Central via REST APIs. During load testing, the API responses suddenly begin returning 429 Too Many Requests HTTP errors.

Which TWO statements accurately describe the API rate limiting architecture in HPE Aruba Networking Central and how the consultant should mitigate this issue? (Choose 2.)

Rate limits are enforced strictly on a per-application (token) basis, with specific thresholds assigned for both requests-per-second and requests-per-day.

The consultant must distribute the API polling script across multiple source IP addresses to bypass Central's ingress IP-based rate limiting firewall.

The consultant should refactor the code to utilize the Central Streaming API (WebSockets) to continuously ingest telemetry without consuming the REST API polling quotas.

Central dynamically increases the API rate limit automatically if the organization purchases and assigns additional AOS-CX Advanced switch licenses to the inventory.

Rate limits are enforced on a global per-customer tenant basis, meaning all independent API scripts across the entire organization share the exact same daily quota pool.

27. A Network Deployment Specialist is executing a complex Zero Touch Provisioning (ZTP) rollout for 300 new AOS-CX access switches. The organization has strict mandates: all switches must run an approved, hardened firmware version (10.12.xxxx) before ANY specific edge configuration (like VLANs or 802.1X ports) is applied.

The specialist configures a Central Template Group (Grp_Campus_Edge) with Firmware Compliance enabled and set to "Install and Reboot".

Template Snippet (Grp_Campus_Edge):

% if tags == 'Role: Edge' %

vlan 10,20,30

interface 1/1/1-1/1/48

vlan access 10

port-access role employee

% endif %

Which THREE statements correctly describe the sequence of events and dependencies during this integrated ZTP and Firmware Compliance workflow? (Select all that apply.)

If the switch fails to obtain a DHCP address on VLAN 1, the Firmware Compliance engine will utilize a localized Bluetooth beacon to push the image from a nearby administrator's mobile device.

The factory-default switch uses DHCP on VLAN 1 to obtain an IP address, resolve the Central URL via DNS, and establish its initial secure outbound connection to the cloud.

Upon joining the Grp_Campus_Edge group, Central immediately applies the Jinja2 template configuration (VLANs 10,20,30) to the switch, and then initiates the firmware download in the background.

Central detects the firmware version mismatch and prioritizes the compliance policy; it pushes the 10.12.xxxx firmware and forces a reboot before pushing the complex edge configuration template.

The switch must have a valid Foundation or Advanced subscription license assigned in HPE GreenLake before it can successfully join the group and trigger the compliance check.

28. A Campus IT Manager is standardizing the port configuration for a new rollout of AOS-CX 6200 access switches. The goal is to fully implement Zero Trust edge security using Dynamic Segmentation integrated with Central and ClearPass.

Central Template Group (Grp_Campus_Edge_6200):

% if role == 'access_switch' %

port-access role UNTRUSTED_IOT

ubt-zone iot_zone

gateway-role default

interface 1/1/1-1/1/48

no shutdown

vlan access 1

port-access

onboard-client-limit 2

port-access security

violation action block

port-access mac-based

enable

port-access dot1x

enable

% endif %

Based on the capabilities of the AOS-CX 6200 series and the provided Central template, which THREE statements accurately describe how this switch handles client onboarding and tunneling? (Select all that apply.)

The 6200 switch inherently translates the 802.1X certificate details into an EVPN-VXLAN Group Policy Identifier (GPID) before executing the local port-access security violation action.

Setting the onboard-client-limit to 2 ensures that the 6200 switch will enforce security by blocking traffic if a third unauthorized device attempts to connect through an unmanaged mini-switch plugged into the wall port.

If an IoT device is assigned the UNTRUSTED_IOT role by ClearPass, the 6200 will utilize its local routing table to forward the traffic, ignoring the ubt-zone command since it requires an Advanced license.

The 6200 switch uses Concurrent Authentication, allowing it to process both MAC-based and 802.1X authentications simultaneously to speed up the onboarding of mixed device types on the same port.

The ubt-zone configuration instructs the 6200 switch to actively encapsulate the authenticated IoT device's traffic into a secure tunnel directed to the centralized AOS-10 Gateway cluster.

29. An HPE Aruba Solutions Consultant is assisting a customer who needs to provide the executive team with a weekly summary of AP uptime, unique client counts, and total bandwidth consumption. The executives do not have user accounts in HPE Aruba Networking Central and do not want to log into a technical dashboard.

Executive Delivery

Which Central reporting feature directly satisfies these specific delivery requirements?

Configure an outbound Webhook via REST API to push raw JSON telemetry data directly to the executives' email inboxes.

Create a Read-Only RBAC role mapped to an external SSO provider (SAML 2.0) so executives bypass the login screen to access the Central dashboard.

Schedule the "Network Summary" report to automatically email a PDF to the executives' distribution list.

Export the Central Audit Trail via the Bulk Data API and use a Python script to format the CLI output into a weekly SMS message.

30. A Network Architect is designing the EVPN-VXLAN overlay for a multi-building campus. The design utilizes AOS-CX 8360 switches at the core and AOS-CX 6300 switches at the edge.

To support centralized management and micro-segmentation via Central NetConductor, how must the overlay routing be orchestrated?

The architect must manually configure static VXLAN tunnels between each AOS-CX 6300 series access switch and the AOS-CX 8360 core switches using the device's local command-line interface (CLI).

OSPF must be configured natively on the overlay virtual network interfaces (VNIs) to aggressively advertise the MAC addresses of connected endpoints.

The AOS-10 Gateway cluster must be configured as the sole Route Reflector (RR), terminating all VXLAN tunnels from the wired edge switches directly.

Central orchestrates EVPN-VXLAN overlay tunnels between fabric edge and border nodes via BGP EVPN control plane.
