When defining zones on FCoE and FC fabrics, which of the following concepts are optional?

An active configuration is mandatory because the zoneset must be activated for the zoning policy to take effect across the FC/FCoE fabric.

A zoneset is a collection of zones and must be defined and activated to apply zoning policies to the fabric.

Aliases, specifically pWWN (Port World Wide Name) aliases or nWWN (Node World Wide Name) aliases, are optional human-readable names assigned to WWNs to simplify zone configuration and management. While they make configurations easier to read and maintain, they are not strictly required for a zone to function.

A zone is the fundamental entity that defines which devices can communicate with each other within a fabric, making it a mandatory concept for zoning.
