   A service provider is deploying segment routing and wants to provide fast reroute (FRR) protection for all destinations in the network. The requirement is that the backup path must be guaranteed to be loop-free regardless of the network topology. Which mechanism should be configured?

   • AMPLS TE FRR with a bypass tunnel
   • BTI-LFA with a post-convergence backup path
   • CLFA with a pre-convergence backup path
   • DRemote LFA with a tunnel to a distant node

   A service provider is deploying SRv6 in its core network. The design team needs to assign a locator to each router. What is the primary purpose of the SRv6 locator?

   • ATo identify a specific link or adjacency between two nodes
   • BTo identify the encapsulation type used for SRv6 packets
   • CTo identify a node or a set of nodes in the SRv6 domain
   • DTo identify a specific service or application on a node

   A service provider is deploying segment routing with flexible algorithms. The network has two classes of traffic: one that must minimize latency and one that must avoid links with a specific administrative color (affinity). The provider wants to use OSPF for one algorithm and IS-IS for the other. What is the correct approach to configure this?

   • AUse TI-LFA for latency and affinity path computation
   • BUse SR-TE with explicit paths for latency and affinity, instead of flexible algorithms
   • CDefine one flexible algorithm for latency in OSPF and another for affinity in IS-IS, and do not enable them in the other IGP
   • DDefine two flexible algorithms, one for latency and one for affinity, and enable both in both OSPF and IS-IS
