  A. set protocols bgp group isp-b multihop

  B. set policy-options policy-statement load-balance then load-balance per-packet

  A customer has the configuration shown in the exhibit applied to the VRF C-PIM domain. What can you determine from this configuration?

  A. The PE is configured for selective PMSI (S-PMSI) only.

  B. The C-RP is collocated on one of the PEs in the MVPN.

  C. The MVPN is not working because the receiver-site command is missing.

  D. Multicast traffic will not switch to the S-PMSI because the vpn-group-address command (data MDT) is missing.

  Correct Answer: B

• Question 73:

  A. sparse mode

  B. sparse-dense mode

  C. dense mode

  D. source specific multicast

  Correct Answer: B

  R1 and R2 are directly connected using the interfaces shown in the exhibit. R1 can ping R2's interface, and R2 can ping R1's interface. The IS-IS adjacency will not come up. What is causing the adjacency to fail?

  A. The correct levels are not configured under protocols isis.

  B. The link MTU is too small to support IS-IS.

  C. Authentication is not properly configured for the adjacency.

  D. Both routers are configured as the DR, causing a conflict.

  Correct Answer: B

• Question 75:

  R3 and R4 want to establish an EBGP session between each other's loopback addresses. Static routes have been configured for the loopback addresses and you can ping from loopback to loopback. Their EBGP sessions are configured with multihop to allow for additional hops. The correct AS numbers have been specified at the [routing-options] hierarchy as well. Considering the topology in the exhibit, which statement is true?

  A. BGP's protocol preference must be adjusted to be lower than protocol static for the session to establish.

  B. Each peer must configure a local-address of their own loopback for the session to establish.

  C. Each peer must specify a local-as within their EBGP configuration for the session to establish. D. Each peer must configure multipath for the session to establish.

  Correct Answer: B

• Question 76:

  You are evaluating a routing policy for an ISP and you find the ^42+ .* (23|9)$ regular expression. Which three AS paths match the regular expression? (Choose three.)

  A. 42 42 42 42 9

  B. 42 42 23 500

  C. 42 42 42 60 9

  D. 42 60 23 9 42

  E. 42 69 500 23

  Correct Answer: ACE

  On your MX Series router, traffic using the critical scheduler is out of profile. All other data is currently in profile. Referring to the exhibit, which statement is correct?

  A. The critical queue is serviced before the less-critical queue.

  B. The critical queue is serviced after the left-over queue.

  C. The critical queue is serviced before the data queue.

  D. The critical queue is serviced before the voice queue.

  Correct Answer: B

• Question 79:

  Area 1 has three network links. You need to summarize the network addresses in Area 1 so that Area 0 sees one route representing the network links. A route to each loopback address must still be visible in Area 0.Which configuration sample on R3 and R5 will complete this task?

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 80:

  You manage an MX series router (with 100 ms buffer size per port) that includes the configuration shown in the exhibit. Traffic marked with DSCP 000101 is entering the ge- 1/0/4 interface at 102 Mbps. The traffic exits the device on the ge-1/0/5 interface. There is no other traffic transiting the router. What happens to traffic exceeding 100 Mbps?

  A. Traffic exceeding 100 Mbps is forwarded.

  B. Traffic exceeding 100 Mbps is buffered.

  C. Traffic exceeding 100 Mbps is redirected to a rate limiter.

  D. Traffic exceeding 100 Mbps is dropped.

  Correct Answer: D
