Nokia Optical Networking Fundamentals Sample Questions (Q26-Q31):

NEW QUESTION # 26
Which statement is correct about the NFM-T network map?

A. It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.
B. It automatically represents all nodes grouped by the location string assigned during the NE creation.
C. It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.
D. It represents all supervised nodes grouped by alarm status (with a different color).

Answer: A

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.

NEW QUESTION # 27
What is the function of a pre-amplifier in an optical network?

A. Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.
B. Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.
C. Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.
D. Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.

Answer: A

Explanation:
A pre-amplifier is an optical amplifier that is used to boost the power of the received optical signal before it is detected by the receiver in an optical communication system. This is done to overcome the loss of power that occurs as the signal travels through the optical fiber and to ensure that the receiver can detect the signal. The pre-amplification stage is typically located close to the receiver in order to minimize the distance that the signal has to travel between the amplifier and the receiver, which helps to reduce the noise and distortion in the signal.

NEW QUESTION # 28
Which statement is correct about node synchronization?

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

Answer: A

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 # 29
Which type of ports are present in the Colorless Wavelength Router (CWR)?

A. Colorless bi-directional ports
B. Colorless uni-directional ports only
C. Black and white ports
D. DeMux ports

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Nokia 1830 PSS (Photonic Service Switch) architecture, the Colorless Wavelength Router (CWR) is a specialized module used within ROADM nodes to enable "colorless" add/drop capabilities. Traditional static multiplexers, like the SFD (Static Filter Device), use fixed-wavelength ports where a specific port is hard-wired to a specific frequency (color). In contrast, a CWR allows any wavelength to be added or dropped from any of its ports.
The ports on a CWR are bi-directional. This means that a single physical port on the CWR card handles both the transmit (Tx) and receive (Rx) paths for a specific wavelength, typically connecting to a transponder's line-side interface. This bi-directional design simplifies fiber management within the shelf and is a key requirement for the "Colorless" attribute of modern flexible grids. By utilizing CWR modules, operators can remotely retune a transponder to a different frequency without needing a technician to physically move fiber patches to a different port on a multiplexer, significantly increasing operational efficiency and reducing human error during service provisioning or restoration.

NEW QUESTION # 30
Is it possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation?

A. Only designs created with current and older releases can be opened and edited.
B. Only designs created with the current release can be opened and edited.
C. No restrictions are imposed on the software release.
D. Designs created with an older release can be opened by a current release but cannot make changes.

Answer: A

Explanation:
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.
