Which of the following statements best describes the output of the CLI command: show wavekey wtmonitor 1/6/LINE summary?
A.
A list of all channels detected against the selected interface (in and out); it shows if a Wave Keys pair is expected, if a Wave Keys pair is received, and if the received Wave Keys pair is unexpected.
B.
A list of all channels on this interface for which any Wave Keys pair is being received.
C.
A list of all channels detected against the selected interface, including Wave Keys pair, channel status, expected and measured power, allowed deviation, and tolerance.

The command show wavekey wtmonitor 1/6/LINE summary displays a list of all channels detected against the selected interface (in and out); it shows if a Wave Keys pair is expected, if a Wave Keys pair is received, and if the received Wave Keys pair is unexpected. A Wave Keys pair is a pair of unique identifiers that are transmitted along with an optical channel to provide channel identification and monitoring functions. The command can be used to verify the presence and correctness of the Wave Keys pairs on an interface and to detect any mismatch or misconfiguration. The other options are incorrect because they either describe a different command or provide incorrect information.
