FCSS – LAN Edge Administrator 7.6 — Question 17

What is the primary purpose of configuring an untagged VLAN on a FortiSwitch port in a network deployment?

Answer options

• A. To enable features like quarantine MAC or dynamic VLAN assignment.
• B. To carry multiple VLANs on a single port.
• C. To enable QoS (quality of service) on the port.
• D. To automatically tag traffic from connected devices.

Correct answer: A

Explanation

The correct answer is A because configuring an untagged VLAN allows for specific features such as quarantine MAC and dynamic VLAN assignment to function properly. Options B, C, and D are incorrect as they describe functions related to tagged VLANs or QoS, which are not the main purpose of an untagged VLAN.
