Nokia Optical Networking Fundamentals Sample Questions (Q20-Q25):

NEW QUESTION # 20
What is the purpose of the NFM-T node synchronization?

A. The partial or full node synchronization allows several entities/items defined at EPT level to be retrieved into the NFM-T database (upload from design).
B. The partial or full node synchronization allows several entities/items defined at NFM-T level to be exported into an XML file, to be used as input for EPT (download to design).
C. The partial or full node synchronization allows several entities/items defined at node level to be retrieved into the NFM-T database (upload).
D. The partial or full node synchronization allows several entities/items defined at NFM-T level to be written into the node database (download).

Answer: D

Explanation:
This is done in order to keep the NFM-T database in sync with the nodes in the network. The synchronization process allows the NFM-T to keep track of any changes that are made to the nodes, such as new nodes added, nodes removed, and so on. By synchronizing the node database with the NFM-T, network administrators can ensure that their network is up to date and running efficiently.

NEW QUESTION # 21
What is the definition of OSNR?

A. The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.
B. The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber including both signal and optical noise.
C. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.
D. The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.

Answer: A

Explanation:
The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth. This is also known as the signal-to-noise ratio (SNR), and it is a measure of how much signal is present in the optical signal compared to the noise, usually expressed in decibels (dB).

NEW QUESTION # 22
Which of the following statements is true about chromatic dispersion (CD)?

A. The fiber attenuation introduces inter-channel interference.
B. Different channels have different bandwidth and this causes different CD performances.
C. Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.
D. The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.

Answer: C

Explanation:
Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed. This phenomenon is known as chromatic dispersion and causes light to spread out as it travels through the fiber over distance, leading to signal attenuation and distortion. The fiber attenuation does not introduce inter-channel interference, but it can cause attenuation of the signal. Different channels have different bandwidths, but this does not affect CD performance.

NEW QUESTION # 23
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?

A. It represents the ability to reroute lambdas to any direction.
B. It represents the ability to drop the same wavelength from different degrees.
C. It represents the ability to support the Fixed Grid standard.
D. It represents the ability to drop any lambda from any Add/Drop block port.

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The term CDC-F stands for Colorless, Directionless, Contentionless, and Flex-grid. While "Colorless" allows any wavelength on any port and "Directionless" allows any port to be routed to any output fiber (degree), Contentionless solves a specific physical limitation of traditional multiplexers. In a standard ROADM, you cannot drop the same wavelength (e.g., Channel 21) from two different directions (e.g., North and West) into the same add/drop structure because they would "contend" or collide on the same internal fiber.
A Contentionless architecture (typically utilizing a Multicast Switch or MCS) allows the node to drop the same wavelength from different degrees simultaneously without interference. This is critical for high-availability mesh networks where a single transponder might need to receive a specific wavelength from a primary path and a backup path. Without contentionless capabilities, operators would have to carefully manage wavelength assignments across the entire network to ensure no two identical frequencies ever meet at the same drop structure, which significantly complicates planning and restoration.

NEW QUESTION # 24
What is the metro area network?

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

Answer: A

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.
