In dual-link hot backup, the AP will establish CAPWAP links with the main AC and backup AC.
The correct answer is A. TRUE. In dual-link hot backup, the AP simultaneously maintains active CAPWAP (Control And Provisioning of Wireless Access Points) tunnels to both the primary (main) AC and the backup AC - making A (TRUE) correct.

Explanation
In dual-link hot backup, the AP simultaneously maintains active CAPWAP (Control And Provisioning of Wireless Access Points) tunnels to both the primary (main) AC and the backup AC - making A (TRUE) correct. This dual-connection design is precisely what distinguishes "hot" backup from "cold" or "warm" backup: because both links are pre-established, failover to the backup AC is near-instantaneous with no reconnection delay. Option B (FALSE) would only be accurate if the architecture were cold standby, where the AP connects to the backup AC only after detecting the primary has failed.
Memory tip: Think of "hot" as "hot and ready" - both CAPWAP links are live at all times, like two engines running simultaneously so the plane never has to restart one mid-flight.
