You have recently configured an aggregated Ethernet interface between two devices in your network. The member links do not all reside within the same PFE complex. You must ensure that the bandwidth and burst size defined in a policer applied to this aggregated Ethernet interface are properly enforced when the traffic falls out of profile.

Which configuration parameter should you use?

A. committed-information-rate

B. committed-burst-size

C. shared-bandwidth-policer

D. physical-interface-policer

You are asked to configure auto-RP as part of a new PIM sparse mode deployment in your network. Which two configuration tasks are required? (Choose two.)

A. All RP routers must be configured with the mapping auto-RP role.

B. All RP routers must be configured with the discovery auto-RP role.

C. All non-RP routers must be configured with the mapping auto-RP role.

D. All non-RP routers must be configured with the discovery auto-RP role.

You must add the 5.0.0.1 OSPF route to the inet.3 routing table for LSP resolution. Which two configuration examples meet this requirement? (Choose two.)

A. Option A

B. Option B

C. Option C

D. Option D

-- Exhibit -- Exhibit -Click the Exhibit button. The Client 1 router forwards a route learned from its EBGP peer to the route reflector RR1. The route

reflector forwards the route to the Client 2 router. However, the Client 2 router uses suboptimal routing to

reach the EBGP route destination.

What would cause this behavior?

A. The route reflector becomes the default forwarding path for packets sent from Client 2 towards the EBGP route destination.

B. The route reflector is using the no-client-reflect parameter.

C. The route reflector has a next-hop self policy for EBGP-learned routes.

D. The route reflector is applying the originator ID attribute to the route.

-- Exhibit

-- Exhibit -Click the Exhibit button. Referring to the VPLS network shown in the exhibit, you notice that only one of the two CE sites configured

under the VPLS instance forms a connection to the remote site. The other site remains in a forwarding and learning mode.

How does PE1 determine which CE within the VPLS instance forms the connection to the remote site?

A. The site that first distributes the outgoing label to the remote site will form the connection.

B. The site with a lower interface index value will form the connection.

C. The site with a higher interface index value will form the connection.

D. The site with the lowest site ID will form the connection.
