CCNA: Cisco Certified Network Associate — Question 1082

Which interface on the WLC is limited to one when LAG is in use?

Answer options

• A. service
• B. virtual
• C. trunk
• D. AP-manager

Correct answer: D

Explanation

The AP-manager interface is unique because only one instance can exist when Link Aggregation Group (LAG) is enabled, allowing for specific management of access points. In contrast, the service, virtual, and trunk interfaces can have multiple instances, making them less restricted in LAG configurations.
