A company requires real-time SAN replication between two remote locations. What is the standard path selection protocol for fabric routing?

A.
FSPF

B.
FICON

C.
FCoE

D.
SCSI

Explanation:
Fabric Shortest Path First (FSPF) is the standard path selection protocol used by Fibre Channel fabrics. The FSPF feature is enabled by default on all Fibre Channel
switches. Except in configurations that require special consideration, you do not need to configure any FSPF services. FSPF automatically calculates the best path
between any two switches in a fabric.
Specifically, FSPF is used to:
•Dynamically compute routes throughout a fabric by establishing the shortest and quickest path between any two switches.
•Select an alternative path in the event of the failure of a given path. FSPF supports multiple paths and automatically computes an alternative path around a failed
link. It provides a preferred route when two equal paths are available.
