Consider the exhibit. A single directional fiber cut is occurring between two amplifiers in bidirectional configuration. Which node(s) will report a "LD Input LOS" alarm?

A.

Node A only

B.

Node B only

C.

Node C only

D.

Node A and Node B

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

A.

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

B.

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.

C.

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

D.

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.

Consider the exhibit. Given the following power readings, what is the calculated span loss from Node A to Node B?

A.

10.0 dB

B.

8.0 dB

C.

5.0 dB

D.

2.0 dB

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

A.

B.

-0.02 to 1.14 dB

C.

0.56 to 1.14 dB

D.

0.56 to 1.72 dB

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?

A.

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

B.

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

C.

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

D.

Traffic does not pass between the local and adjacent nodes.

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/UNEIN detail

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

A.

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

B.

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

C.

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

D.

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

Which of the following statements about using Nokia product documentation in the troubleshooting process is TRUE?

A.

Before investigating a problem it is important to check the Engineering and Planning Tool User Guide (EPTUG) if a possible issue has already been acknowledged by the Product Unit (PU).

B.

The Customer Release Notes (CRNs) provides instructions to perform the automated provisioning, commissioning, and power balancing functions in a customer network based on the Nokia 1830 PS5 platform.

C.

Before investigating a problem it is important to check the User Provisioning Guide (UPG) if a possible issue has already been acknowledged by the Product Unit (PU).

D.

The Customer Release Notes (CRNs) document collects documented solved known issues, new issues discovered after the product software has been released.as well as software upgrade procedures and firmware details.

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

A.

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

B.

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

C.

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

D.

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

Which of the following statements about the "config powermgmt egress 1/2 adjust status command" is TRUE?

A.

The command displays the status of power adjustment on the specified egress amplifier.

B.

The command enables power adjustment feature on the specified egress amplifier, as this feature Is always and only available at the egress amplification stage.

C.

The command enables power adjustment feature on the specified egress amplifier.

D.

The command displays commissioning status and WT decoder usage for the specified egress amplifiers only, as this feature is always and only done in the egress direction.
