Nokia Optical Networking Fundamentals Sample Questions (Q60-Q65):

NEW QUESTION # 60
What is the definition of OSNR?

A. 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.
B. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.
C. The OSNR is defined as the ratio between the average optical signal power and the average 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: C

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 # 61
What is a trail?

A. A physical link between two optical amplifiers
B. An entity to encapsulate a low order signal into a high order container
C. A transparent transport of a client signal
D. A link between end points to increase the power budget of the optical link

Answer: C

Explanation:
A trail is a transparent transport of a client signal. A trail is a physical link between two points in an optical network, allowing for the transport of a client signal from one point to the other. It is a low-order signal, such as a 10G Ethernet or a Fibre Channel signal, encapsulated into a high-order container, such as a 40G or 100G signal. This allows for the transport of the client signal over longer distances, increasing the power budget of the optical link.

NEW QUESTION # 62
Which sentence about NFM-T is correct?

A. NFM-T is used to design and manage optical network
B. 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
C. NFM-T fully supports optical and IP nodes
D. NFM-T is used to provision optical services having IP nodes as extremities

Answer: D

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 # 63
What is the purpose of the validate step in the EPT design process?

A. This step is used to measure optical power performances over an existing network before making changes.
B. During this step, the configuration available on the involved network elements is compared with the design provided by EPT.
C. This step is optional and is useful to verify the network element layout before going through the commission step.
D. During this step, the run design action is triggered for network design consistency check and errors fixing.

Answer: D

Explanation:
The validate step in the EPT design process is used to trigger the run design action, which is responsible for verifying the consistency of the network design and fixing any errors that may exist. During the validation process, the system will compare the configuration available on the involved network elements and the design provided by EPT, and any discrepancies will be flagged for further investigation or correction.

NEW QUESTION # 64
With reference to the image, where is the OPS card placed to provide the OMSP protection?

A. Between the transponders and the mux/demux
B. Before the transponder, on the client side, towards the external device
C. Between the mux/demux and the amplifier
D. After the amplifiers

Answer: B
