CompTIA Network+ (N10-006) — Question 86

Which of the following describes what occurs with the ID of a specified native VLAN when traffic passes over a trunk?

Answer options

• A. It becomes the gateway of last resort for the switch or router.
• B. it becomes the default VLAN for the untagged frames.
• C. it becomes the priority ID for all the VLAN traffic across the device.
• D. It becomes the default gateway for the port or ports.

Correct answer: B

Explanation

The correct answer is B because the native VLAN is used for untagged frames on a trunk link, allowing them to be correctly processed. Option A is incorrect as the native VLAN does not act as a gateway, while option C misrepresents the role of the native VLAN, and option D confuses the native VLAN with the default gateway, which are separate concepts.
