Q: 18
An engineer is setting up the WLC to support a high-density design for a lecture hall. The engineer
must modify the existing high-density RF protocol to obtain a smaller cell size. Also, the clients must
connect to the nearest AP using the highest possible data rates. Which setting
allows this design?

Is the main requirement to limit cell size or prioritize client distribution? If it's mainly about balancing connections, I'd pick B.
C not D. D is tempting since RX-SOP helps with interference, but for actual cell size reduction power threshold (C) is what the exam looks for.
Isn’t there a catch if the high-density protocol specifically wants to reduce co-channel interference rather than just shrink the cell? In that case, wouldn’t tweaking RX-SOP threshold (D) make more sense than just lowering power (C), since RX-SOP directly limits what signals get heard? But the question said "smaller cell size", so does it really rule out D?
Probably C. Lowering power threshold is always suggested in official study guides and labs for this type of high-density wireless scenario.
Its C, power threshold. Lowering the AP's transmit power will reduce the cell size which is needed for dense environments like lecture halls. This also pushes clients to connect to closer APs at higher data rates because they're not hearing distant APs as well. Pretty sure that's the main idea here, but happy to hear if anyone sees it differently.
C, Client distribution (B) helps balance users, but for shrinking cell size in high-density, power threshold (C) is the right setting here.
