Which of the following commands is used to retrieve the total output power level?

• A.show interface am212 5a 1/6/lineout pm
• B.show interface am2125a 1/6/lineout detail
• C.show interface am2125a 1/6/lineout
• D.show interface am2125a 1/6/lineout wavekey

Which of the following statements about the alarm masking mechanism is TRUE?

• A.The alarm masking mechanism preserves the events' original time stamps, when related alarms gets hidden and then eventually displayed because of the mechanism itself, so that the user can still know the date and time of the original issue.
• B.The alarm masking mechanism makes sure that alarms are always present on the downstream interfaces to facilitate the troubleshooting process.
• C.The alarm masking mechanism always forwards masked alarms to an external Network Management System (NMS) for alarm correlation.
• D.The alarm masking mechanism updates the events' original time stamps when it masks/shows alarms, so that when an alarm is not masked anymore, the user can see the updated date and time associated with the original issue.

Suppose a Raman amplifier has been plugged into slot 1/8. Which command should the user enter to retrieve the total optical power detected at the ingress interface?

• B.show interface 1/8 power
• C.show Interface 1/8/LINEIN
• D.show interface 1/8 opin

Which of the following statements best describes the output of the CLI command: show wavekey wtmonitor
1/6/LINE summary?

• A.A list of the unexpected channels detected against the selected interface.
• B.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.
• 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.
• D.A list of all channels on this interface for which any Wave Keys pair is being received.
