Nokia Optical Networking Fundamentals Sample Questions (Q27-Q32):

NEW QUESTION # 27
Is it possible to modify node parameters within the edit EPT menu?

A. No, this view is used to display a close-up view of the node
B. Yes, but the user can modify only the node name and location
C. Yes, the user can apply manual changes directly from this view
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

Answer: D

Explanation:
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. The edit EPT menu allows the user to view information about a node but is not used to modify node parameters. The user can only apply manual changes to non-GMPLS nodes, as the control plane reserves node resources which cannot be modified by the user.

NEW QUESTION # 28
Which sentence about NFM-T is correct?

A. NFM-T is used to provision optical services having IP nodes as extremities
B. NFM-T fully supports optical and IP nodes
C. NFM-T is used to design and manage optical network
D. NFM-T fully supports LO, LI, L2 and GMPLS applications and it is mainly focused on 1830 PSS, as well as other older product families

Answer: A

Explanation:
NFM-T is a network management system designed to manage optical networks in a unified manner. It is used to design, manage, and provision optical services having IP nodes as extremities. It supports a variety of technologies, including optical and IP, and fully supports LO, LI, L2, and GMPLS applications. It is mainly focused on the Nokia 1830 PSS product family, as well as other older product families.

NEW QUESTION # 29
WDM allows transmission systems to:

A. Transport multiple signals transparently, onto several wavelengths, all together over one single fiber
B. Increase the bit rate of each client signal by spreading it over multiple wavelengths
C. Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission
D. Allocate different signals to different time slots

Answer: A

NEW QUESTION # 30
Which of the following statements is true?

A. Logs report both active and historical events.
B. Alarms and conditions report a real time status of the node.
C. Alarms and conditions report only historical status of the node.
D. Logs report a real time status of the node.

Answer: A

Explanation:
A log is a record of events that have occurred within a system, such as a network device or an application. Logs can include information about system activity, configuration changes, and error messages. They can be used for troubleshooting, auditing, and compliance purposes. Logs can report both active (real-time) and historical events that have occurred within a system.
Alarms and conditions, on the other hand, are used to notify operators of real-time status of the node, such as when a threshold is breached or when a specific event occurs. Alarms and conditions are typically used to provide real-time notifications of potential problems or issues, while logs are used to provide a historical record of what has occurred.

NEW QUESTION # 31
Which of the following sentences about FlexGrid is false?

A. The FlexGrid is currently standardized by ITU-T.
B. FlexGrid systems use specific sets of boards. Old generation WDM systems need to be upgraded to support FlexGrid.
C. FlexGrid allows a more efficient channel spacing.
D. Channels in FlexGrid systems are allocated with a granularity of 27.5GHz.

Answer: B

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.
