Explanation: When using VLAN the number and size of collision domains remain the same -> A is not correct.
VLANs allow to group users by function, not by location or geography -> B is correct.
VLANs help minimize the incorrect configuration of VLANs so it enhances the security of the network -> C is correct.
VLAN increases the size of broadcast domains but does not decrease the number of collision domains -> D is not correct.
VLANs increase the number of broadcast domains while decreasing the size of the broadcast domains which increase the utilization of the links. It is also a big advantage of VLAN -> E is correct.
VLANs are useful but they are more complex and need more administration -> F is not correct.
