In the given scenario, the goal is to restrict users on the network between R1 and R2 from accessing the external network through R5, while still allowing them access to all resources within the administrative domain. The correct approach is to configure an Access Control List (ACL) that permits traffic to all internal networks and denies traffic to any external address. This ACL should be applied to the R2 interface that connects to R1 in the ingress direction. By doing so, traffic originating from users between R1 and R2 destined for external networks will be blocked, while internal traffic will be allowed.

 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)

The difference between SNMP (Simple Network Management Protocol) and model-driven telemetry lies in their data delivery mechanisms. Telemetry allows for modeled network data to be pushed to network administrators on an as-needed basis, providing real-time insights into network performance and health. On the other hand, SNMP typically relies on polling mechanisms where network administrators request data at specific intervals. References: Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide
