Nokia Optical Networking Fundamentals Sample Questions (Q16-Q21):

NEW QUESTION # 16
WDM allows transmission systems to:

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

Answer: A

NEW QUESTION # 17
Which statement is correct about node synchronization?

A. Full synchronization retrieves the correlated alarms from the node
B. Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)
C. Node synchronization is executed to align the time of the node to the time of the NFM-T platform
D. Node synchronization is executed to test the reachability of a node

Answer: B

Explanation:
Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.

NEW QUESTION # 18
What is the meaning of demand in EPT?

A. Demand refers to the required capacity of a single network element in terms of bandwidth.
B. Demand refers to the required number of trails to be automatically created to meet design requirements.
C. Demand refers to the amount of OTN interfaces within a single network element.
D. Demand refers to one or more client signal.

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the context of the Nokia 1830 Engineering and Planning Tool (EPT)-now known as WaveSuite Planner (WS-P)-a Demand is a fundamental planning object that represents the customer's traffic requirement between two or more nodes. Specifically, it refers to one or more client signals that need to be transported across the optical network. When a user defines a demand in EPT, they specify the source and destination nodes, the type of client service (e.g., 10GE, 100GE, or STM-64), the quantity of these services, and the required protection level (e.g., Unprotected, 1+1, or O-SNCP).
The tool uses these defined demands to calculate the most efficient optical path, select the appropriate hardware (transponders and muxponders), and determine the necessary wavelength assignments. While a demand eventually results in the creation of optical trails and utilizes network element capacity, the term itself strictly refers to the input traffic requirement or the client signal(s) that the network is being designed to carry. Without defining demands, the planning tool cannot generate a Bill of Materials (BOM) or perform power balancing simulations, as it wouldn't know the traffic load the physical infrastructure must support.

NEW QUESTION # 19
Which sentence about NFM-T is correct?

A. NFM-T is used to provision optical services having IP nodes as extremities
B. NFM-T is used to design and manage optical network
C. NFM-T fully supports optical and IP nodes
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 # 20
What is the metro area network?

A. The metro area network is located between access and core domains.
B. The metro area network is that portion of network that passes through a city to provide connections to several customers.
C. The metro area network is made of OCS/SWDM nodes only, as no pure photonic nodes are used here.
D. The metro area network is located in between two access area networks and made of photonic nodes only (no OCS/SWDM nodes are used there).

Answer: B

Explanation:
The Metro Area Network (MAN) is a telecommunications network that spans a metropolitan area and connects multiple local area networks (LANs) or business networks together. It typically covers an area that is larger than a LAN but smaller than a wide area network (WAN). The purpose of a MAN is to provide a high-bandwidth, low-latency communication infrastructure for businesses and other organizations in a metropolitan area.
