Only one zone set can be activated at any time.
D.
A zone can only be a member one zone set.
E.

F.

There is one Zoneset active per VSAN , and not one only. The answer tat is supposed to be correct is not correct when it comes to Cisco devices that support more that one VSAN and thus more than one Active Zone set.
•Zone reactivation (a zone set is active and you activate another zone set) does not disrupt existing traffic.
•Each VSAN can have multiple zone sets but only one zone set can be active at any given time.
