Which path selection protocol is used by Fibre Channel fabrics?

The correct answer is C. FSPF. FSPF (Fabric Shortest Path First) is the standard link-state routing protocol defined for Fibre Channel fabrics. It is analogous to OSPF in IP networks: each switch maintains a topology database, runs the Dijkstra SPF algorithm to compute the shortest path tree, and uses the…

Explanation

FSPF (Fabric Shortest Path First) is the standard link-state routing protocol defined for Fibre Channel fabrics. It is analogous to OSPF in IP networks: each switch maintains a topology database, runs the Dijkstra SPF algorithm to compute the shortest path tree, and uses the results to populate its routing tables for domain-to-domain forwarding. FSPF also supports equal-cost multipath. The other answers serve different roles: IVR routes between VSANs, VoQ is a queuing mechanism, VSANs provide logical isolation, and SANTap is a data-replication tap service.
