Nokia Optical Networking Fundamentals Sample Questions (Q46-Q51):

NEW QUESTION # 46
What is a degree-1 node?

Answer: A

Explanation:
A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.


NEW QUESTION # 47
Which of the following statements about the ODUk unit is TRUE?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Optical Transport Network (OTN) hierarchy, the ODUk (Optical Data Unit of order k) is the fundamental unit for electronic grooming and switching. Unlike the OTUk layer, which is tied to a specific physical optical interface and includes the Forward Error Correction (FEC), the ODUk layer is "path-oriented." This means that in a switched WDM system like the Nokia 1830 PSS-24x, the ODUk containers can be switched across a backplane from one line card to another without needing to deconstruct the entire optical signal.
To clarify the other options: Option A is false because FEC is part of the OTUk (Transport Unit) layer. Option C is false because ODUk processing is entirely electrical (O-E-O must occur to access the ODUk overhead). Option D is false because the OPU (Optical Payload Unit) is actually the "first" container where the client signal is mapped; the ODUk then wraps around the OPU to add path-level monitoring and maintenance signals. Therefore, the ODUk acts as the "virtual container" that allows the network to manage services end-to-end across multiple optical spans.


NEW QUESTION # 48
Which of the following sentences about FlexGrid is false?

Answer: A

Explanation:
FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

NEW QUESTION # 49
Is it possible to modify node parameters within the edit EPT menu?

Answer: B

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.


NEW QUESTION # 50
Is it possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation?

Answer: B

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.
