Question 1

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

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

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

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

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

Answer : C

The GMRE activation status is reported in the supervision state column on the node list. The supervision state column displays the GMRE status of the node, which is either 'Activated' or 'Not Activated'. This allows the user to quickly check the GMRE activation status of a node without having to ping the node from the NFM-T platform.

Question 2

Is it possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation?

AOnly designs created with the current release can be opened and edited.

BOnly designs created with current and older releases can be opened and edited.

CDesigns created with an older release can be opened by a current release but cannot make changes.

DNo restrictions are imposed on the software release.

Answer : B

It is possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation, however only designs created with current and older releases can be opened and edited. Designs created with an older release can be opened by a current release but changes cannot be made.

Question 3

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

AIt automatically represents all nodes grouped by the location string assigned during the NE creation.

BIt represents all supervised nodes grouped by alarm status (with a different color).

CIt allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.

DIt allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.

Answer : C

The NFM-T network map provides a graphical view of the network with different colors used to represent each node, physical connection, and active alarm. It allows the user to quickly identify any issues in the network and provides context sensitive navigation.

Question 4

What is a degree-1 node?

AA node with only one direction and therefore a terminal node

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

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

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

Answer : A

A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.

Question 5

Which of the following sentences about FlexGrid is false?

AFlexGrid allows a more efficient channel spacing.

BChannels in FlexGrid systems are allocated with a granularity of 27.5GHz.

CFlexGrid systems use specific sets of boards. Old generation WDM systems need to be upgraded to support FlexGrid.

DThe FlexGrid is currently standardized by ITU-T.

Answer : C

FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

Question 6

With reference to the image, where is the OPS card placed to provide the OMSP protection?

AAfter the amplifiers

BBetween the mux/demux and the amplifier

CBetween the transponders and the mux/demux

DBefore the transponder, on the client side, towards the external device

Answer : D

Question 7

Which of the following is an example of optical protection mechanism?

AOptical regeneration (e.g., back-to-back regeneration)

BOSNCP (e.g., via Y-cable or OPS card)

CGMPLS-enabled SBR

DGR and SBR combined

Answer : B

It can be implemented through the use of a Y-cable or an optical protection switch (OPS) card, which allows for the switching of traffic to a secondary path in the event of a failure on the primary path. This type of protection is commonly used to protect against fiber cuts and other types of physical layer failures in the optical transport network.
