CCNA: Cisco Certified Network Associate — Question 938

A network architect is deciding whether to implement Cisco autonomous access points or lightweight access points. Which fact about firmware updates must the architect consider?

Answer options

• A. Unlike lightweight access points, which require redundant WLCs to support firmware upgrades, autonomous access points require only one WLC.
• B. Unlike autonomous access points, lightweight access points require a WLC to implement remote firmware updates.
• C. Unlike lightweight access points, autonomous access points can recover automatically from a corrupt firmware update.
• D. Unlike autonomous access points, lightweight access points store a complete copy of the current firmware for backup.

Correct answer: B

Explanation

The correct answer is B because lightweight access points rely on a Wireless LAN Controller (WLC) for firmware updates, while autonomous access points do not. Option A is incorrect as it misrepresents the relationship with WLCs; option C is incorrect because lightweight access points do have recovery mechanisms; option D is incorrect since autonomous access points do not depend on WLCs for firmware storage.
