What is the area covered by a single AP called?
The correct answer is A. BSA. Option A, BSA (Basic Service Area), is correct because it is the standard IEEE 802.11 term for the wireless coverage zone created by a single Access Point - it defines the geographic boundary within which clients can associate with that AP. ESA (Extended Service Area) is wrong…

Explanation
Option A, BSA (Basic Service Area), is correct because it is the standard IEEE 802.11 term for the wireless coverage zone created by a single Access Point - it defines the geographic boundary within which clients can associate with that AP.
ESA (Extended Service Area) is wrong because it refers to the combined coverage of multiple APs connected through a distribution system, forming an Extended Service Set (ESS), not a single AP's zone. SSA is not a defined standard wireless networking term and serves as a plausible-sounding distractor. TSA is similarly not a wireless networking term - it is commonly associated with the Transportation Security Administration, making it an easy elimination.
Memory tip: Think "B" for "Basic" and "one" - a single AP provides the most basic, foundational coverage cell, so BSA pairs with one AP, while ESA (Extended) pairs with many.
