Question 730
An operations ticket for Summit Research has two requirements: (1) change the untagged VLAN on a trunk to match a remote neighbor, and (2) prevent an unused VLAN from crossing a trunk link. Which proposed plan satisfies both outcomes?
Explanation
Correct Answer
Both outcomes are covered: (1) Native VLAN mismatch can place untagged traffic into different Layer 2 broadcast domains. (2) The allowed list determines which tagged VLANs may traverse the trunk. Neither action is a substitute for the other.
Incorrect Answers
The first step covers (1), but the second addresses deploy standalone wireless connectivity at a tiny site without a central WLC. An autonomous or locally managed AP does not depend on a separate enterprise WLC for all management. It leaves outcome (2) unfulfilled.
Neither step is the requested pair: Configure an appropriate WPA2/WPA3-Enterprise WLAN with RADIUS is for enforce per-user identity authentication for an enterprise WLAN, and Configure the AP switchport for the intended management access VLAN is for connect a lightweight AP expecting one untagged management VLAN on an access port. Enterprise WLAN security uses 802.1X/EAP against an authentication server. The proposed plan misses the two stated outcomes.
The second step covers (2), but the first addresses detect unauthorized wireless transmitters without serving client associations. A monitor-mode radio can scan spectrum and clients for management/security without providing ordinary access. It leaves outcome (1) unfulfilled.
