A. Route reflectors do not change any existing BGP attributes by default when advertising routes.

B. A BGP peer does not require any configuration changes to become a route reflector client.

C. Clients add their originator ID when advertising routes to their route reflector

D. Route reflectors add their cluster ID to the AS path when readvertising client routes.

Which statement is true regarding BGP FlowSpec?

A. It uses a remote triggered black hole to protect a network from a denial-of-service attack.

B. It uses dynamically created routing policies to protect a network from denial-of-service attacks

C. It is used to protect a network from denial-of-service attacks dynamically

D. It verifies that the source IP of the incoming packet has a resolvable route in the routing table

C. Internal L1 PDUs are flooded to all L1 routers in other areas.

D. Internal L1 PDUs are only flooded to the local area's L1 routers.

E. External L2 PDUs are only flooded to the local area's L2 routers.

An interface is configured with a behavior aggregate classifier and a multifield classifier How will the packet be processed when received on this interface?

A. The packet will be discarded.

B. The packet will be processed by the BA classifier first, then the MF classifier.

C. The packet will be forwarded with no classification changes.

D. The packet will be processed by the MF classifier first, then the BA classifier.

Which two statements are correct about IS-IS interfaces? (Choose two.)

A. If a broadcast interface is in both L1 and L2, one combined hello message is sent for both levels.

B. If a point-to-point interface is in both L1 and L2, separate hello messages are sent for each level.

C. If a point-to-point interface is in both L1 and L2, one combined hello message is sent for both levels.

D. If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level
