  What is the main difference between the OSPF NSR and OSPF NSF mechanisms?

  A. NSR does not use as much memory resource as NSF does.
  B. With NSR, OSPF on the newly active standby RP initially has no state information.
  C. On NSR, the neighbors must be NSR-aware.
  D. With NSR, the router that performs the switchover preserves the state internally.

  A. Terminating PPP sessions at the service provider
  B. L2TP tunnelling
  C. GRE tunnelling
  D. PPP multiplexing
  E. PPP framing
  A. Terminating PPP sessions at the service provider
  B. L2TP tunnelling

• Question 903:

  Refer to the exhibit.

  

  Each AS domain contains more than one BGP router. Site-B sends traffic to ISP-1 over a directly connected link, but Site-B is not used as an AS transit for the ISP-1 backbone. How should the routes be advertised by ISP-1 towards Site-B to accomplish this task?

  A. Prefixes from site-A should be advertised with the no-export community
  B. Prefixes from site-B should be advertised with the no-export community
  C. Prefixes from site-B should be advertised with the no-advertise community
  D. Prefixes from site-A should be advertised with the as-path prepend attribute
  E. Prefixes from site-A should be advertised with the no-advertise community
  B. Prefixes from site-B should be advertised with the no-export community

• Question 904:

  Which three Layer 2 VPN pseudowire components are true? (Choose three.)

  A. attachment circuit
  B. bandwidth requirement
  C. route distinguisher
  D. virtual circuit label
  E. pseudowire identifier
  F. route target
  A. attachment circuit
  D. virtual circuit label
  E. pseudowire identifier

• Question 905:

  Which option is the benefit of per-link LFA over per-prefix LFA?

  A. It has a greater applicability
  B. It provides greater protection coverage
  C. It is simpler
  D. It enables better bandwidth utilization
  C. It is simpler

• Question 906:

  Two OSPF neighbor routers are stuck in the EXSTART state. After a while, the neighborship goes down. A network engineer is debugging the issue when both routers show the OSPF log message "too many retransmissions." What is the possible root cause?

  A. OSPF area mismatch
  B. OSPF hello-interval mismatch
  C. interface MTU mismatch
  D. interface network type mismatch
  C. interface MTU mismatch

• Question 907:

  Refer to the exhibit. Which description of the BGP status between these two routers is true?

  

  A. The EBGP status is down due to the CoPP applied on R1.
  B. The EBGP status is oscillating between down and established due to the CoPP applied on R2.
  C. The EBGP status is down due to the CoPP applied on R2.
  D. The EBGP status is established because the CPPr applied on both routers does not affect the BGP peering
  D. The EBGP status is established because the CPPr applied on both routers does not affect the BGP peering

• Question 908:

  Drag the MPS label format on the left onto the correct target on right.

  Select and Place:

  

  

• Question 909:

  Which statements about the Route Target Rewrite feature are not true? (Choose two.)

  A. After the route target replacement policy is applied to the target router, the BGP session need not be refreshed manually to put the policy into operation.
  B. Route Target Rewrite allows the administration of the routing policy to stay local to the AS.
  C. Route target replacement is always done by the ASBR.
  D. Route target rewrites are supported for VRF export maps.
  E. Route target replacement can be done on incoming and outgoing BGP updates.
  A. After the route target replacement policy is applied to the target router, the BGP session need not be refreshed manually to put the policy into operation.
  C. Route target replacement is always done by the ASBR.

• Question 910:
