Which two statements are correct in this scenario? (Choose two.)

2. While deploying class of service on an EX Series switch, what are two aspects of the scheduler? (Choose two.)

3. Your organization uses 802.1X with a RADIUS server. If the RADIUS server stops responding, you want the fallback action to continue to permit access for devices that currently have authorization but deny any new access attempts.

Which fallback action provides this capability?

4. Which statement about LLDP and LLDP-MED operations on EX Series devices is correct?

5. Click the Exhibit button.

You want to provide better performance for the video traffic that traverses your network. The video traffic enters your network without any class-of-service markings.

According to Juniper Networks, which two classification methods are performed by the routers shown in the exhibit? (Choose two.)

6. You have configured DSCP CoS in your network and have applied BA and multifield classifiers to all interfaces.

In this scenario, which statement is correct?

7. You are deploying a new campus switching environment using Ex Series switches. This new environment includes IP phones requiring Power over Ethernet (PoE) and end-user client PCs attached to a single switch port that will be configured with 802.1X authentication.

Considering the default configuration on an EX Series access switch and the configuration requirements to support this deployment, which two statements are correct? (Choose two.)

8. Which two statements are correct when using the no-loss forwarding class? (Choose two.)

9. Which three statements about VSTP are correct? (Choose three.)

10. Which statement accurately describes the operation of OSPF within the Junos OS?

11. Click the Exhibit button.

Referring to the exhibit, which two statements are correct? (Choose two.)

12. You are enabling CoS throughout your enterprise network using the DSCP bits. You plan to use an MF classifier on all edge devices while using BA classifiers on all transit core devices.

In this scenario, what should you use to provide consistent handling of traffic?

13. You are troubleshooting a multicast deployment in a network. Some multicast groups operate in PIM-ASM mode and others operate in PIM-SSM mode.

While troubleshooting, you note the following:

- The network uses IGMPv2 for some segments and IGMPv3 for others.

- For group 232.1.1.1, receivers know the exact source IP of the multicast sender.

- For group 239.10.10.10, receivers do not know the source address in advance.

Which two statements correctly describe the operational differences between these two modes in Junos OS? (Choose two.)

14. When configuring OSPF, what is the purpose of adding the secondary command to an OSPF interface?

15. Which two statements correctly describe how EX Series switches use captive portal for Layer 2 authentication? (Choose two.)

16. You have created a private community VLAN called RND. The private community VLAN works fine within switch S1, but traffic in the private RND community VLAN does not reach VLAN members connected to switch S2.

Which statement is correct in this scenario?

17. 1.You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically be provided with their geographic location details by the EX Series switches.

In this scenario, which protocol should be used to enable this behavior?

18. Click the Exhibit button.

What is the OSPF router type shown in the exhibit for router 192.168.2.1?

19. Click the Exhibit button.

Your network receives the full Internet BGP routing table from two different ISPs. You want your local routers to use Provider A to forward all Internet traffic as long as Provider A is available.

Referring to the exhibit, which two actions would satisfy this requirement? (Choose two.)

20. Click the Exhibit button.

Referring to the exhibit, what is required for the BGP peering to establish?

21. Click the Exhibit button.

You configured MVRP in your Layer 2 network using the configuration shown in the exhibit. You verified that the appropriate VLANs are configured and applied on the two access switches. You are using RSTP as your loop prevention mechanism. Unfortunately, the users are not able to communicate with their corresponding server attached to the Access-2 switch.

In this scenario, what should you do to solve this problem?

22. Which two statements are correct about multicast routing tables? (Choose two.)

23. Your OSPF network consists of a mix of 1GbE and 10GbE interfaces. By default, all interfaces have the same cost in your OSPF network You are asked to ensure that the 10GbE interfaces are more preferred when available.

In this scenario, which two statements would accomplish this behavior? (Choose two.)

24. Click the Exhibit button.

Referring to the exhibit, R2 receives a packet from the multicast source on its ge-0/0/4.0 interface.

Which two statements are correct in this scenario? (Choose two.)

25. You have several switches in your network that use Cisco's PVST+ protocol. You want your Juniper switches to interoperate with those devices.

In this scenario, which protocol would you use?

26. You are configuring CoS throughout your enterprise network using DSCP. You have configured MF classification on your edge devices and are using BA classifiers throughout the core. You are using the EZQoS template provided on your Ex Series switches that are acting as your edge devices.

You have loaded the configuration group and applied it to the appropriate interfaces. Classification and scheduling are working properly on your edge devices; however, traffic is not being classified correctly when it reaches your core devices.

In this scenario, which statement is correct about solving this problem?

27. Click the Exhibit button.

You are deploying a new campus switching environment using various EX Series switch models. The devices attached to one of the new EX Series switches include IP phones, loT devices, and wireless access points (APs) requiring power over Ethernet (PoE) with varying power requirements. A sample output from one of these switches is shown in the exhibit.

In this scenario, which two statements are correct? (Choose two.)

28. You are deploying a new campus switching environment using EX Series switches that will use class of service.

Regarding the use of congestion control mechanisms, which two statements are correct? (Choose two.)

29. You have two multicast receivers connected to the same VLAN. You notice that the switch that they are connected to is forwarding multicast traffic out of all the ports in the same VLAN, instead of just the two ports for the connected multicast receivers.

In this scenario, what would you configure to optimize multicast forwarding?

30. You must implement EVPN signaling on an EX Series device that is configured with both underlay and overlay networks.
