Question1: After committing the following configuration change on your MPLS VPN PE router, all MPLS VPN destinations become unreachable.

Which additional configuration solves the issue?
A:

B:

C:

D:

Question2: Click the Exhibit button.

You administer AS 65000, and have deployed a route reflector (RR1) in your network as shown in the exhibit. The traffic between AS 65001 and AS 65002 is going through the route reflector, even though it is not the best path.
What will solve this problem?

Question3: Click the exhibit button.

What would be the expected outcome from the configuration shown in the exhibit?

Question4: Which statement is correct regarding BGP route reflectors?

Question5: Click the Exhibit button.

The exhibit shows a BGP peering session for two PE routers. The BGP session is up, but IPv4 hosts in the Layer 3 VPN that use the BGP session are unable to communicate.
What is the problem?

Question6: According to Juniper Networks, what are three methods of scaling Layer 2 VPNs? (Choose three.)

Question7: You want to use IS-IS on a GRE interface where the underlying Layer 3 MTU is 1500.
Which statement is correct in this scenario?

Question8: You are asked to deploy VPLS in your network as a new service for several customers, and you must identify the configuration and provisioning requirements for your customers. Which two statements are correct in this scenario? (Choose two.)

Question9: Which two routes use a proper route distinguisher? (Choose two.)

Question10: Which two LSA types are permitted in an OSPF stub area? (Choose two.)

Question11: Click the Exhibit button.

Site HQ connects to Site A through a provider using BGP. The BGP route for Site A destinations is redistributed info OSPF within site HQ. You provision a backup link over a dedicated leased line that connects to Site A, which should only be used when Site A is not reachable through the provider.
When the backup circuit is provisioned, traffic destined to Site A transits the backup link instead of the provider link.
Referring to the exhibit, how do you solve this problem?

Question12: Click the Exhibit button.

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

Question13: Your company has multiple upstream BGP connections to the Internet through ISP-A, ISP-B, and ISP-C.
You want to ensure that all traffic coming into your network uses ISP-A.
How would you accomplish this task?

Question14: 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.)

Question15: Click the Exhibit button.

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

Question16: Click the Exhibit button.

Referring to the ABR configuration shown in the exhibit, which two statements are correct? (Choose two.)

Question17: Click the Exhibit button.

Referring to the exhibit, which statement is correct?

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: You are asked to configure PIM-SM in your network. Your implementation must allow for load sharing between redundant RPs and, should an RP failure occur, the RP failover time should be minimized.
Which two configuration tasks are required in this scenario? (Choose two.)

Question20: With which two elements is a VRF table populated? (Choose two.)

Question21: 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?

Question22: Which neighbor state indicates that two BGP neighbors have full connectivity?

Question23: Click the Exhibit button.

Referring to the exhibit, what is the correct prefix length of the route for the multihomed device?

Question24: Click the Exhibit button.

Which two statements are true about the route shown in the exhibit? (Choose two.)

Question25: You are configuring a BGP-signaled Layer 2 VPN service.
Which two statements are true in this scenario? (Choose two.)

Question26: How is a BGP Layer 2 VPN prefix formed by a PE?

Question27: Click the Exhibit button.

Referring to the exhibit, you have multiple Layer 3 VPNs established in your network. You are asked to ensure that PE-4 allows CE-2 in VPN 1 to communicate with CE-1 in VPN 3.
Which two statements are correct in this scenario? (Choose two.)

Question28: Which message type initiates the BGP session?

Question29: 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?

Question30: Click the Exhibit button.

The customer's hosts cannot communicate across their Layer 3 VPN. The exhibit shows the configuration for the two PE devices in the Layer 3 VPN.
What should you do to solve the problem?

Question31: Click the Exhibit button.

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

Question32: 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?

Question33: Click the Exhibit button.

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.)

Question34: Click the Exhibit button.
