Nokia Optical Networking Fundamentals Sample Questions (Q59-Q64):

NEW QUESTION # 59
Which of the following are the main reasons for fiber attenuation?

A. Chromatic dispersion (CD) and polarization mode dispersion
B. Refraction and reflection
C. Scattering and absorption
D. Small channel spacing

Answer: C

Explanation:
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.

NEW QUESTION # 60
With reference to the image, where is the OPS card placed to provide the OMSP protection?

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

Answer: C

NEW QUESTION # 61
What is a trail?

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

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
What is the purpose of the NFM-T node synchronization?

A. The partial or full node synchronization allows several entities/items defined at node level to be retrieved into the NFM-T database (upload).
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 NFM-T level to be written into the node database (download).
D. 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).

Answer: C

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 # 63
Is it possible to modify node parameters within the edit EPT menu?

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

Answer: A

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.
