Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 5

A network administrator wishes to implement VLAN 10 to isolate certain users. It is common however for these users to often change their physical location. Which of the following VLAN implementations should be used?

Answer options

• A. Port based VLAN assignment.
• B. Protocol based VLAN assignment.
• C. MAC based VLAN assignment.
• D. IP subnet based VLAN assignment.

Correct answer: C

Explanation

The correct choice is C, MAC based VLAN assignment, as it allows for VLAN membership to be determined by the MAC address of the devices, making it ideal for users who frequently change locations. In contrast, port-based VLAN assignment (A) ties users to specific switch ports, which is not flexible; protocol-based (B) is based on the type of traffic, and IP subnet-based (D) relies on fixed IP addresses, both of which are not suitable for users with variable locations.
