Refer to the exhibit.

An engineer at ISP C is configuring a new interconnection with ISPs A and B using the BGP protocol. After the initial configuration, the engineer noticed high memory usage and an abnormally large LIB table on router R2. Which two actions must the engineer take on R2 to minimize memory usage? (Choose two.)

A. Configure the mpls ldp neighbor 11.11.11.11 labels accept 1 command.

B. Configure Standard ACL 1 with accepted prefixes.

C. Configure Extended ACL 101 with accepted prefixes.

D. Configure the mpls ldp neighbor 1.1.1.1 labels accept 101 command.

E. Configure the mpls ldp neighbor 21.21.21.21 labels accept 101 command.

How does SR policy operate in Segment Routing Traffic Engineering?

A. An SR policy for color and endpoint is deactivated at the headend as soon as the headend learns a valid candidate path for the policy.

B. When "invalidation drop" behavior occurs, the SR policy forwarding entry is removed and the router drops all traffic that is steered into the SR policy.

C. When a set of SID lists is associated with the SR policy designated path, traffic steering is ECMP-based according to the qualified cost of each SID-list.

D. An active SR policy installs a BSID-keyed entry in the forwarding table to steer the packets that match the entry to the SR policy SID-list.

Refer to the exhibit. Customer_A asked ISP_A to connect two offices via an MPLS L3 VPN. Customer_A is currently using only the default route toward ISP_A. The engineer at ISP_A already configured the ip route vrf Customer_A

172.16.10.0 255.255.255.0 10.10.10.1 command on R1. Which action completes the configuration?

A. Configure the redistribute static and redistribute connected commands on R1.

B. Enable the bgp default route-target filter and default-information originate commands under the global BGP configuration on R2.

C. Configure the route-target both 200:1 and route-replicate vrf Customer_A commands under the ip vrf configuration on R2.

D. Configure the network 172.16.10.0 and redistribute-internal static commands under the BGP address family for Customer_A in the global BGP configuration on R1.
