You have configured a BGP-signaled Layer 2 VPN with the configuration shown in the exhibit.
Which two statements are true in this situation? (Choose two.)

Question17: Click the Exhibit button.

Referring to the exhibit, what information must be acquired about AS65200's configuration for AS65100 to build an interprovider VPN between PE1 to PE2?

Question18: You have deployed class of service on your network. You notice that the single strict-high queue is starving traffic to all other queues. What will help to ensure that all queues receive the desired transmission rates?

Question19: Click the Exhibit button.

Referring to the exhibit, the Layer 2 VPN between PE-1 and PE-2 is not functioning properly.
What must you do to solve the problem?

Question20: Click the Exhibit button.

Referring to the exhibit, which statement is correct?

Question21: The network team will be performing maintenance on R3. The maintenance window requires a reboot of router R3. You want to gracefully move traffic away from R3 until after the reboot. In this scenario, how would you solve this problem?

Question22: You are troubleshooting a Layer 3 VPN issue. The VPN has been passing traffic successfully for some time, but now it is reported that traffic is no longer flowing. You look into the bgp.l3vpn.0 table and see newly hidden routes.
What would be the cause of this problem?

Question23: Click the Exhibit button.

Referring to the exhibit, what must be added to the existing configuration to ensure that per-prefix load balancing occurs?

Question24: Click the Exhibit button.

R1 and R2 are not forwarding the routes received from a remote PE to their customers.
Referring to the exhibit, which parameter must be added to the configuration to allow the routes to be forwarded?

Question25: Which two statements are correct regarding site IDs and circuit IDs in a VPLS routing instance? (Choose two.)

Question26: Which message type initiates the BGP session?

Question27: Click the Exhibit button.

While logging in to routers on your network, you find the exact configuration shown in the exhibit on multiple devices.
Which multicast RP strategy is being used in this scenario?

Question28: Click the Exhibit button.

Referring to the topology shown in the exhibit, where will the attached bit be set?

Question29: Click the Exhibit button.

You have configured the OSPF network as shown in the exhibit. However, R4 and R5 do not have connectivity to prefixes outside of Area 10. In this scenario, what will solve this problem?

Question30: Click the Exhibit button.

Which two statements are true regarding the output shown in the exhibit? (Choose two.)

Question32: Click the Exhibit button.

Referring to the exhibit, when building an interprovider VPN Option C between AS65100 and AS65200, which two parameters must be configured on the EBGP connection between PE1 and PE2? (Choose two.)

Question33: You are asked to configure a new Layer 3 VPN.
In this scenario, which routing-instance type must be used?

Question34: To reduce the size of OSPF Area 100, you configure the area with the no-summariesparameter. After committing this configuration change, you notice that an OSPF router in a remote area is no longer receiving Type 5 LSAs from an ASBR in Area 100.
