* Incoming optical signals are boosted by the ingress amplifier.
* Outgoing optical signals do not pass through the ingress amplifier.

* Incoming optical signals are boosted by the ingress amplifier.
* Outgoing optical signals pass through the ingress amplifier but are not boosted.

* Incoming optical signals pass through the ingress amplifier but are not boosted.
* Outgoing optical signals are boosted by the ingress amplifier.

* Incoming optical signals are boosted by the ingress amplifier.

Q25. A power adjustment has succeeded conditionally because of gain settings set to higher levels than expected by design. Which of the following alarms will raise?

Invalid topology (PRCDRERR-TOPO)

Amplifier Gain Tilt Adjustments Suspended (PWRTILTSUSP)

Power Adjustment Failure (PWRADJFAIL)

Gain Adjustment Exceeded Max Value (PWRMAXGAIN)

Q26. Consider the exhibit which shows an EPT Power Management Report referring to an ingress amplifier. What is the available output optical power range?

-0.6 to 1.72 dB

-0.02 to 1.14 dB

0.56 to 1.14 dB

0.56 to 1.72 dB

Q27. Suppose a node is experiencing a little unexpected attenuation over the Optical Supervisory Channel (OSC) transmit direction. Which of the following statements is FALSE?

No OSC-related alarms will raise on the local node.

A “Data Link Down” alarm will raise on the adjacent node.

A Power adjustments action will fail on the local node.

Traffic will pass between the local and adjacent node.

Q28. Which of the following statements about 1-Day PMs is TRUE?

1-Day PMs show measurements collected over the preceding 24 hours. Up to 8 bins are available for data storing.

1-Day PMs show measurements collected since the beginning of the current day. Up to 8 bins are available for data storing.

1-Day PMs show measurements collected over the preceding 24 hours. Up to 33 bins are available for data storing.

1-Day PMs show measurements collected since the beginning of the current day. Up to 33 bins are available for data storing.

Q29. Which of the following statements about the alarm masking mechanism is TRUE?

The alarm masking mechanism makes sure that alarms are always present on the downstream interfaces to facilitate the troubleshooting process.

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.

The alarm masking mechanism always forwards masked alarms to an external Network Management System (NMS) for alarm correlation.

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.

Q30. Consider the exhibit which shows part of an EPT Schematic View. Which number refers to the Wavelength Router (WR8-88) block?

show interface 1/8 opin

show interface 1/8 power

show Interface 1/8/LINEIN

show interface 1/8/UNEIN detail

Q32. Which of the following CLI commands displays a list of the expected and measured output power for the channels whose admin state is up?

config wavekey power detail

show wavekey wtsource

config wavekey summary

show wavekey wtsource power

Q33. Consider the exhibit. What do the different colored green columns indicate?

Optical power levels measured multiple times against a specific interface, at 24-hour intervals for the same wavelength.

Optical power levels measured for multiple wavelengths against a specific interface.

Optical power levels measured at different interfaces throughout the optical path of a single wavelength.

The average optical power levels measured for multiple wavelengths throughout their shared optical path.

0.56 to 1.14 dB

0.56 to 1.72 dB

A list of cross-connections, including A-end, Z-end, frequency, ID number, OCH trail name, and administrative/operational states.

A list of boards that this cross-connection passes through on the local node, along with administrative/operational states, expected power levels, and measured power levels.
