 ISP delegation to PCE servers involves assigning specific tasks or roles to different PCE servers within a network. Option A refers to adding a new PCE server with lower precedence than the primary PCE, which means introducing an additional server that has less priority in task execution compared to the existing primary one. Option B involves changing the precedence of any of the PCE servers, indicating a modification in their hierarchical order or priority for task execution. References := Cisco Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR)

To reduce network usage and minimize leave latency for users connected to VLAN 76, the configurations should focus on efficient multicast traffic management. Option A likely involves enabling IPv6 MLD snooping, which restricts multicast traffic to only the ports that have members interested in receiving the traffic, thus reducing unnecessary network usage. Option C might include configuring fast-leave processing, which allows the switch to immediately stop forwarding multicast traffic to a port when the last member of a multicast group leaves, reducing leave latency.

 The configuration in the exhibit shows the implementation of Nonstop Forwarding (NSF) with OSPF. NSF is used to minimize the downtime of neighbor relationships during a Route Processor (RP) switchover. The nsf command enables NSF, and ietf specifies the use of the IETF standard for graceful restart in OSPF. The restart interval 90 sets the time, in seconds, within which the restarting router should complete its restart, helping to maintain uninterrupted forwarding despite the switchover.
