While troubleshooting a VoWLAN call quality issue on a Cisco Unified Wireless IP Phone 7925 on a
Cisco Unified Wireless Network, a network administrator views a compilation of outputs from the
WLAN settings and client connection status, as shown in the exhibit. From the information shown,
which one of these characteristics about the problem is true?

A.
The RSSI is outside of the recommended specifications for voice.

B.
The client keeps getting put into a blacklisted state due to client exclusions because Cisco
Centralized Key Management and EAP-FAST are incompatible.

C.
The WLAN does not have a DHCP server assigned and therefore the client is not getting an IP
address.

D.
The SNR is outside of the required RF specifications for voice.
