Question

Quizplus · Accepted Answer

The principle disadvantage of VLAN "membership by port group" is that the network manager must reconfigure VLAN membership when an end system moves from one port to another. This can lead to administrative overheads and potential errors if not managed correctly. Option A is incorrect as it refers to "VLAN tagging" which examines portions of the MAC frame above the MAC layer, and is not specifically related to "membership by port group". Option B is not a disadvantage, but rather a requirement for any VLAN deployment. Option C is also incorrect as "membership by port group" is considered to be relatively easy to configure.
