After a help-desk change disables PMK caching on capable court-house laptops, users report slower Wi-Fi handoffs on the stairs between floors. What is the most accurate takeaway?
Select an answer to reveal the explanation.
Short Explanation
PMKSA caching is like remembering the handshake so you do not reintroduce yourself at every doorway. Turn it off on capable clients and those stairwell roams can feel sticky and slow. Caching helps roam speed—it is not a substitute for the right security type.
Full Explanation
PMKSA (pairwise master key security association) caching allows supported clients to reuse keying material and complete secure roams more quickly. Disabling it on otherwise capable clients commonly increases re-authentication delay during AP-to-AP transitions. It does not replace encryption requirements and is unrelated to captive-portal content.
