Explanation

Dual band operation with Band Steering is correct because Band Steering works by suppressing or delaying probe responses on the 2.4 GHz band to push capable clients toward 5 GHz. A 2.4 GHz-only client physically cannot associate on 5 GHz, so when Band Steering holds back 2.4 GHz responses waiting for a 5 GHz probe that never comes, the client can fail to associate entirely on its first attempt.

Why the distractors are wrong:

• A (Content filtering): Controls what web content authenticated users can reach - has no effect on RF association.
• B (Bridge mode): A Layer 2 forwarding setting (bridged vs. NAT) that determines how traffic flows after association, not whether a client can associate.
• C (802.11r): Fast BSS Transition - speeds up roaming between APs for already-connected clients; it does not gate first-time associations.

Memory tip: Think of Band Steering as a bouncer trying to redirect everyone to the VIP (5 GHz) line. A 2.4 GHz-only device can't get into the VIP line, but the bouncer keeps waving it away from the regular line too - leaving it stuck at the door.
