Major

Minor

Warning

NEW QUESTION 28
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.

NEW QUESTION 29
Which of the following statements best describes the payload type setting?

Payload type attribute is recorded within the client payload and must be entered manually.

Payload type attribute Is recorded within the client payload and can be set automatically.

Payload type attribute is recorded within the OTN overhead and must be entered manually.

Payload type attribute is recorded within the OTN overhead and can be set automatically or manually.

NEW QUESTION 30
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.

NEW QUESTION 31
Which of the following is NOT a characteristic of an Optical Supervisory Channel Loss of Signal (OSC LOS) issue, in case that no “LD Input LOS” alarms are raised against the involved amplifiers?

An “Incoming SUPVY LOS” alarm is raised on the local node.

A “Data Link Down” alarm is raised on the adjacent node.

A “Power Adjustment Required” alarm is eventually raised on the local node.

Traffic does not pass between the local and adjacent nodes.

NEW QUESTION 32
Which of the following statements correctly describes where power adjustments can be performed?

In bidirectional configurations, ingress power adjustments are performed against the ingress amplifiers, while egress power adjustments are performed against the egress amplifiers.

In bidirectional configurations, both ingress and egress power adjustments are performed against the ingress amplifiers only.

In unidirectional configurations, both ingress and egress power adjustments are performed against the ingress amplifiers only.

When Raman pumps are used, both ingress and egress power adjustments are performed against the Raman pump directly.

NEW QUESTION 33
Consider the exhibit. A single directional fiber cut is occurring between two amplifiers in unidirectional configuration with Raman pump.
Multiple services are crossing the affected span.
Which node(s) will report an Incoming Payload LOS” alarm?

No node, as a Raman pump is used in Node A.

Node C only.

Both Node A and Node C

Neither Node A nor Node C.

NEW QUESTION 34

1. Retrieve the channel power trace.
2. Determine the active clock reference source.
3. Switch to alternate clock source (PF).
4. Replace the suspect PF.
