Which of the following descriptions about thin AP is correct?

Question

Options

• AThin AP is also called wireless router
• BThin APs are gradually being replaced by fat APs due to lack of functions
• CThin AP cannot be configured alone and must be used in conjunction with the wireless controller
• DThin AP can implement 802.1X authentication, encryption and other functions, and other functions

Explanation

Thin APs (lightweight access points) are designed to offload all intelligence - configuration, security policy, and management - to a centralized wireless controller, meaning they literally cannot operate alone; option C is correct. Option A is wrong because a wireless router is a separate device that combines routing and AP functions independently, which is closer to a fat AP concept. Option B has the relationship backwards: fat APs are actually being phased out in enterprise environments in favor of thin AP deployments, because centralized controller-based management is far more scalable. Option D describes fat AP capabilities - functions like 802.1X authentication and encryption are handled by the wireless controller in a thin AP architecture, not by the AP itself.

Memory tip: Think of "thin" as thin on brains - a thin AP is just a radio with antennas; all the intelligence lives in the controller. "Fat" AP is fat with features because it handles everything on its own.
