Q
Why is it important to add VLAN identifiers to the frames when they move from one VLAN to another VLAN?
AA. To identify which VLAN they belong to
BB. To identify which switch they belong to
CC. To identify which host they belong to
DD. To identify which router they belong to
Correct Answer:
A. A. To identify which VLAN they belong to
Explanation:
Generally, no host knows to which VLAN it belongs to and it is the switch who takes the responsibility of tagging VLAN identifiers to frames. Before placing a packet on the trunk link, the packet should have VLAN identifier to be identified uniquely.
