200-301 Question #1369: Real Exam Question with Answer & Explanation

Question

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?

Options

• AUnlike lightweight access points, which require redundant WLCs to support firmware upgrades,
• BUnlike autonomous access points, lightweight access points require a WLC to implement remote
• CUnlike lightweight access points, autonomous access points can recover automatically from a
• DUnlike autonomous access points, lightweight access points store a complete copy of the current

Explanation

A critical distinction for firmware updates between Cisco autonomous and lightweight access points is the dependency of lightweight APs on a Wireless LAN Controller (WLC).

Common mistakes.

• A. Redundant WLCs provide high availability for the wireless network, but the fundamental requirement for a WLC to perform firmware upgrades on lightweight APs is not tied specifically to redundancy.
• C. Both types of APs can have various recovery mechanisms, but this statement describes a general capability rather than the specific dependency for firmware updates related to their architectural differences.
• D. Lightweight APs typically download their firmware from the WLC during operation, and while they store a current copy, the crucial fact for firmware updates is the WLC dependency for the update process itself, not just local storage.
