Below are 5 free demo questions to help you preview the practice tests:

Question 1:

Which of the following headend behaviors can insert SRHs into IPv6 packets?
A. H.Encaps.Red
B. H.Insert
C. H.Encaps
D. H.Insert.Red
Answer: B, C, D
Explanation:
Segment Routing over IPv6 (SRv6) defines several headend behaviors for how SRH (Segment Routing Headers) are added:
B. H.Insert — Inserts an SRH into an existing IPv6 packet.
C. H.Encaps — Encapsulates the original packet in a new IPv6 packet with an SRH.
D. H.Insert.Red — Performs insert behavior and reduces the payload for optimization.
A. H.Encaps.Red is not a defined SRv6 behavior — it’s an invalid option.
Exact Extract – Huawei SRv6 White Paper:
“H.Insert, H.Insert.Red, and H.Encaps are valid behaviors for injecting SRH. H.Encaps.Red is not defined in the SRv6 headend behavior set.”

Question 2:

Node segments in SR-MPLS must be manually configured.
A. TRUE
B. FALSE
Answer: B
Explanation:
Node segments in SR-MPLS (Segment Routing over MPLS) are typically automatically generated and distributed via IGP protocols (such as IS-IS or OSPF) using SR extensions. There is no need to manually configure node segments on every router.
Exact Extract – Huawei HCIE-Datacom Study Guide – Segment Routing:
“Node SIDs are automatically generated and advertised by IGPs with SR extensions. Manual configuration is not required except in special cases like adjacency SIDs.”

Question 3:

Which of the following issues do DiffServ model-based QoS have?
A. It involves only single-hop behaviors and does not change the network topology.
B. Independent resources cannot be provided for users.
C. It does not change service behaviors. If bursty traffic in a single flow is too heavy, congestion still occurs.
D. The number of queues is small, and SLA assurance cannot be provided for specific users. As a result, deterministic delay assurance cannot be provided.
Answer: A, B, C, D
Explanation:
DiffServ QoS model operates on per-hop behavior (PHB) and has these limitations:
A. ✅Single-hop behavior; no end-to-end path awareness.
B. ✅Cannot guarantee dedicated resources to individual users.
C. ✅Does not address traffic bursts; congestion is still possible.
D. ✅Queue limitations hinder fine-grained SLA assurance and deterministic delay.
Exact Extract – HCIE-Datacom QoS Section: “DiffServ provides PHB without path-level control. It cannot guarantee SLA for individual users due to limited queuing mechanisms and lack of end-to-end visibility.”

Question 4:

314.Which of the following commands are mandatory for configuring an OSPF-based SR-MPLS TE tunnel? (Select All that Apply)
A. Configure the LSR ID for routers.
B. Enable segment routing in the OSPF process view.
C. Enable the opaque capability of OSPF.
D. Enable MPLS TE in the OSPF process view.
Answer: A, B, C, D
Explanation:
To configure an SR-MPLS TE tunnel based on OSPF, all four options are mandatory:
A. Configure the LSR ID – LSR ID is required as the unique identifier of the router in MPLS and TE.
B. Enable segment routing in the OSPF process view – Needed to advertise segment information (SID).
C. Enable the opaque capability – Opaque LSAs are used to carry SR and TE information in OSPF.
D. Enable MPLS TE in the OSPF process view – Ensures that TE-related attributes (e.g., bandwidth) are advertised in OSPF LSAs.
Exact Extract – Huawei HCIE-Datacom SR-MPLS TE Configuration Guide:
“To support SR-MPLS TE over OSPF, it is necessary to configure the LSR ID, enable SR and MPLS TE capabilities in OSPF, and activate the OSPF opaque capability for carrying TE and SR attributes.”

Question 5:

Which of the following is the default port used by iMaster NCE-Campus northbound open APIs?
A. 18008
B. 18006
C. 18002
D. 18000
Answer: B
Explanation:
The default port for iMaster NCE-Campus northbound RESTful APIs is 18006. This port is used by external platforms and applications to interact with iMaster NCE via its open API interface.
Exact Extract – Huawei iMaster NCE-Campus API Integration Guide:
“Northbound interfaces of iMaster NCE-Campus are accessible via port 18006 by default. This allows external systems to use open APIs for automation and integration.”
