Question 5
Which of the following sentences about FlexGrid is false?
Options:
A.
FlexGrid allows a more efficient channel spacing.
B.
Channels in FlexGrid systems are allocated with a granularity of 27.5GHz.
C.
FlexGrid systems use specific sets of boards. Old generation WDM systems need to be upgraded to support FlexGrid.
D.
The FlexGrid is currently standardized by ITU-T.
Answer:
C
Explanation:
Explanation:
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
Which statement is correct about the NFM-T network map?
Options:
A.
It automatically represents all nodes grouped by the location string assigned during the NE creation.
B.
It represents all supervised nodes grouped by alarm status (with a different color).
C.
It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.
D.
It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.
Answer:
C
Explanation:
Explanation:
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.
