Question # 6

Is it possible to modify node parameters within the edit EPT menu?

A.

Yes, the user can apply manual changes directly from this view

B.

Yes, but the user can modify only the node name and location

C.

No, this view is used to display a close-up view of the node

D.

Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user

Question # 7

Which of the following statements is true about chromatic dispersion (CD)?

A.

Different channels have different bandwidth and this causes different CD performances.

B.

The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.

C.

Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.

D.

The fiber attenuation introduces inter-channel interference.

Question # 8

How is it possible to check the activation status of GMRE on a node?

A.

The GMRE reachability can be tested via ping request from NFM-T

B.

The ControlPlane status column on the node list displays the GMRE status for the selected node

C.

The GMRE activation status is reported in the supervision state column on the node list

D.

The GMRE activation status is reflected on the color of the icon representing the node

Question # 9

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

A.

The partial or full node synchronization allows several entities/items defined at node level to be retrieved into the NFM-T database (upload).

B.

The partial or full node synchronization allows several entities/items defined at NFM-T level to be written into the node database (download).

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 exported into an XML file, to be used as input for EPT (download to design).

Question # 10

Where is the OPS card equipped to provide the optical channel protection?

A.

Between the transponder and the amplifiers

B.

Between the filters and the amplifiers

C.

Before the transponder, on the clientside, towards the external device

D.

Between the transponder and the filter

Question # 11

What is a degree-1 node?

A.

A node with only one direction and therefore a terminal node

B.

A node with only one express channel and therefore made of two sides

C.

A node with only east and west sides without directions towards north and south

D.

A node with one direction only and therefore used as In-Line-Amplifier (ILA)

Question # 12

Which statement is correct about node synchronization?

A.

Full synchronization retrieves the correlated alarms from the node

B.

Node synchronization is executed to test the reachability of a node

C.

Node synchronization is executed to align the time of the node to the time of the NFM-T platform

D.

Full synchronization retrieves all items from the node (NE parameters.Ports, Alarms, Internal Links,etc)
