• Question 61:

  Click the Exhibit button.

  

  Referring to the exhibit, the source is currently sending multicast traffic using group 224.1.1.1, which is being received by R1. R2 is not receiving PIM register messages.

  What would be the cause of this problem?

  A. Tunnel services have not been enabled on R1.

  B. All routers have not been configured with the same Auto-RP discovery group.

  C. R5 has not received an IGMP report of 224.1.1.1.

  D. A(*,G) tree has not been built yet.

  Correct Answer: C

• Question 62:

  Click the Exhibit button.

  

  Referring to the exhibit, you must advertise the 100.0.0.0/16 routes from AS1 to AS2, but R2 is not advertising any BGP routes to R5.

  Why is this happening in this scenario?

  A. The IBGP routes will not be advertised because you must use a policy to advertise IBGP routes.

  B. The IBGP routes are not active and EBGP will advertise only active routes.

  C. The IBGP routes will not be advertised because the AS path shows as incomplete.

  D. The IBGP routes are not active because the next hop is not reachable.

  Correct Answer: B

• Question 66:

  Click the Exhibit button.

  

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

  A. There can be more than one OSPF neighbor on the ge-0/0/1 interface.

  B. There can be more than one OSPF neighbor on the ge-0/0/0 interface.

  C. There is no need for a DR for the ge-0/0/0 interface.

  D. The DR election process is not finished for the ge-0/0/0 interface.

  Correct Answer: AC

• Question 67:

  You have an IPv4 multicast network configured as PIM-SM.

  What must be done before replacing your static RP with auto-RP?

  A. Enable sparse-dense mode on each of the routers in the network.

  B. Configure auto-RP domains on each router in the network.

  C. Configure each router in the network as a candidate BSR.

  D. Enable each router in the network to forward multicast packets.

  Correct Answer: A

• Question 68:

  You have multiple BGP routes to the same prefix with equal local-preference values and AS-path lengths. In this scenario, which route will be preferred in the route selection process?

  A. The route with the least preferred origin value.

  B. The route with the lowest MED value.

  C. The route with the most preferred origin value.

  D. The route with the highest MED value.

  Correct Answer: C

• Question 69:

  Click the Exhibit button.

  

  Referring to the exhibit, you configured a new multifield classifier for the ge-1/2/0 interface to move ICMP traffic to the best-effort queue and traffic from 192.168.20.0/24 to the expedited forwarding queue. You received notice that some applications are not working after the change.

  Which configuration change will remedy the problem?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 70:

  Click the Exhibit button.

  

  There is a functioning OSPFv3 neighborship between Router-1 and Router-2 over the ge-0/0/1 link. However, the 172.100.100.0/24 and 172.101.101.100/24 routes are not being shared through OSPFv3.

  Referring to the configuration shown in the exhibit, which two actions must you take to solve the problem? (Choose two.)

  A. Add interface ge-0/0/1 under the IPv4 unicast realm for both routers.

  B. Add the IPv6 family protocol under ge-0/0/2 for both routers.

  C. Add the lo0 interface under OSPFv3 for both routers.

  D. Add interface ge-0/0/2 under OSPFv3 for both routers.

  Correct Answer: AB
