You administer a small WLAN with nine access points. As a small business, you do not run a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-Personal in all APs and clients. Several users are now reporting the inability to connect to the network at times and it is constrained to one area of the building. When using a WLAN scanner, you see that the AP covering that area is online and has a strong signal. No other changes have been made to the environment and all access points are the same model.
What is the likely problem?
A . The AP that covers the problem area requires a firmware update
B . The clients are improperly configured
C . The AP that covers the problem area has failed
D . The AP that covers the problem area is improperly configured
Answer: A
