Which description of a multiple-initiator target zone is true?

In Cisco MDS switches, TCAM entries for zoning are allocated per source-destination pair; a multiple-initiator target zone with N initiators and one target generates N TCAM entries compared to just one entry for a single-initiator single-target zone. This increased TCAM consumption is a key reason why SAN best practices recommend single-initiator single-target zoning to optimize switch TCAM utilization.

Multiple-initiator target zoning actually reduces the total zone count by consolidating multiple initiators into one zone per target, rather than requiring a separate zone for each initiator-target pair.

A multiple-initiator zone consumes more TCAM space than a single-initiator single-target zone because each additional initiator requires its own source-destination TCAM entry to be stored.

Multiple-initiator zones do not block RSCNs between initiators; all zone members receive RSCNs from other members within the zone, which is one reason single-initiator zoning is preferred to prevent unnecessary RSCN propagation.
