QUESTION NO: 4
R1 has a BGP session with a router that has a peer autonomous system number of 64501. It is exchanging routes, and is advertising those routes to IBGP peers. The downstream IBGP peers, however, cannot pass traffic to the advertised networks.
Referring to the exhibit, which configuration change must occur to solve this problem?

A. The BGP group ext-64501 must include the export next-hop-selfpolicy. B. The BGP group int-64503 must include the import next-hop-selfpolicy. C. The BGP group ext-64501 must include the import next-hop-selfpolicy. D. The BGP group int-64503 must include the export next-hop-selfpolicy.

Correct Answer: D

QUESTION NO: 5

QUESTION NO: 6
You want to prevent rogue BPDUs from lab devices reaching the internal through the Lab_Switch device.

Referring to the exhibit, what should be done to accomplish this task?

A. Configure protocols rstp with the bpdu-block-on-edge parameter for interface xe-0/2/0 B. Configure an input filter on interface xe-0/2/0 to discard the RSTP packets C. Configure the three lab ports as edge ports D. Configure the three lab ports under the protocols layer2-control bpdu-block hierarchy on the switch

Correct Answer: D

QUESTION NO: 7
Referring to the exhibit, why is this OSPF adjacency remaining in this state?

A. A subnet mask mismatch exists between the OSPF neighbors. B. An MTU mismatch exists between the OSPF neighbors. C. A hello interval mismatch exists between the OSPF neighbors. D. An area ID mismatch exists between the OSPF neighbors

NSR is independent of helper routers to assist the routing platform in restoring routing protocol information. D. NSR is dependent on helper routers to assist the routing platform in restoring routing protocol information.

Correct Answer: B,C

QUESTION NO: 9
Which two statements correctly describe RSTP port roles? (Choose two.)

A. The alternate port is a standby port for an edge port. B. The backup port is used as a backup for the root port. C. The root port is responsible for forwarding data to the root bridge. D. The designated port forwards data to the downstream network segment or device.
