B. It selects a remote router, reachable through a tunnel defined by a single Node-SID.

C. It selects an immediate neighbor.

D. It selects a remote router, reachable through a tunnel defined by a Node-SID and one or two Adjacency-SIDs.

A. Using a flex-algo Node-SID as an explicit hop in the path definition of an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

B. Specifying the flex-algo instance ID as an additional TE constraint for an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

C. Configuring and applying a VRF import policy to a VPRN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.

D. Configuring and applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.
