In the described remote-office network, which VLAN ID is designated for management traffic?

• A. 100
• B. 200
• C. 300
• D. 400

Answer: (A)

Carrying management traffic on its own VLAN keeps the control plane isolated from user data, which improves security, reliability, and ease of access control. In this remote-office design, management traffic is assigned to VLAN ID 100, so all devices’ management interfaces (switches, APs, any controllers) use this VLAN for administrative access. This separation means admin activity isn’t affected by user data traffic and is protected from untrusted endpoints. Ensure trunk links carry VLAN 100 and apply strict ACLs to limit access to the management subnet. The other VLAN IDs would typically serve different purposes (such as user data or other services) and aren’t designated for management in this scenario.
