Which statement is correct about the NFM-T network map?

• A.It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.
• B.It represents all supervised nodes grouped by alarm status (with a different color).
• C.It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.
• D.It automatically represents all nodes grouped by the location string assigned during the NE creation.

What is the function of a pre-amplifier in an optical network?

• A.Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.
• B.Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.
• C.Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.
• D.Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.

What is the purpose of the NFM-T node synchronization?

• A.The partial or full node synchronization allows several entities/items defined at NFM-T level to be exported into an XML file, to be used as input for EPT (download to design).
• B.The partial or full node synchronization allows several entities/items defined at node level to be retrieved into the NFM-T database (upload).
• C.The partial or full node synchronization allows several entities/items defined at EPT level to be retrieved into the NFM-T database (upload from design).
• D.The partial or full node synchronization allows several entities/items defined at NFM-T level to be written into the node database (download).

What is the purpose of the validate step in the EPT design process?

• A.This step is optional and is useful to verify the network element layout before going through the commission step.
• B.This step is used to measure optical power performances over an existing network before making changes.
• C.During this step, the configuration available on the involved network elements is compared with the design provided by EPT.
• D.During this step, the run design action is triggered for network design consistency check and errors fixing.

When monitoring the quality of the received signal in WDM, an open eye indicates:

• A.Low noise
• B.High distortion
• C.High jitter
• D.Presence of high inter-symbolic interference
