How does opportunistic key caching speed up the roaming process?
- A. When a station authenticates, the AP sends encryption keys to the controller, which distributes them to all APs in the mobility domain.
- B. When a station decides to roam, it notifies its AP, which then distributes the pair wise master key of the stations to APs in its mobility domain.
- C. After a station authenticates with an AP, it pre-authenticates with neighboring APs, which cache the pair wise master key in case the station later roams.
- D. When SNR of a station begins to drop, it pre-authenticates with neighboring APs, which cache the pair wise master key of the station for a user-defined amount.
Correct Answer: B 🗳️
