200-150 · Question #169
Refer to the exhibit. What is the result when you run the command?
The correct answer is A. All switches in the fabric receive the active zone set.. Activating a zone set on a Cisco MDS switch distributes it immediately to all switches in the fabric using CFS, ensuring consistent zoning enforcement fabric-wide.

Why each option
Activating a zone set on a Cisco MDS switch distributes it immediately to all switches in the fabric using CFS, ensuring consistent zoning enforcement fabric-wide.
When the zoneset activate command is executed on a Cisco MDS switch, Cisco Fabric Services (CFS) automatically propagates the active zone set to every switch in the fabric in real time. This ensures all fabric members enforce the same zoning policy without requiring manual distribution or switch reboots.
Zone set activation is not a local-only operation by default; CFS distribution ensures the change is pushed to all fabric members immediately upon activation.
Zone set distribution via CFS is instantaneous upon activation and does not require any switch reboot before receiving the updated zone set.
The command activates a specific named zone set, not the default zone set; the default zone is a separate policy that permits all devices to communicate only when no explicit zone set is active.
