Options

ADisable the device group
BRemove all members from the device group

Explanation

To successfully delete a BIG-IP device group, all members must first be removed from it.

Common mistakes.

A. There is no direct 'disable' state for a device group itself in BIG-IP; devices are managed as members of the group.
C. While removing the decommissioned device is a necessary step, the device group cannot be deleted if other members still remain in it.
D. Ensuring all members of a device group are in sync is a operational best practice, but it is not a prerequisite for deleting the device group.
