Question No. 1

What is a Shared Risk Group (SRG)?

Show Answer Hide Answer
Correct Answer: D

According to the Nokia Optical Networking documentation, a Shared Risk Group (SRG) is defined as 'a set of network resources that share a common failure risk. When a resource in an SRG fails, the other resources in the group are also affected.' This can include fibers, boards, nodes, and other network resources. The SRG concept is used in network design and protection mechanisms to ensure survivability and minimal impact on service in case of a failure.


Question No. 2

What is the OAMP LAN interface?

Show Answer Hide Answer
Correct Answer: B

It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management. This interface is used to connect the OAMP node to the LAN, allowing it to be managed and monitored remotely.


Question No. 3

With reference to the image, where is the OPS card placed to provide the OMSP protection?

Show Answer Hide Answer
Correct Answer: D

Question No. 4

By using the EPT run design command, are the previously designed elements removed?

Show Answer Hide Answer
Correct Answer: B

The EPT run design command can remove previously designed elements, but the user is prompted to choose whether to delete them or leave them intact. This allows the user to progress their design while still keeping the existing elements in place. If the user selects to leave the existing elements, then they will remain in the same slots. If GMPLS nodes are used, the existing slots cannot change as they are controlled by another manager (GMRE).


Question No. 5

Which use case is most suitable for the deployment of a star topology?

Show Answer Hide Answer
Correct Answer: A

A star topology is a network design where all devices are connected to a central hub, which acts as a central point of control and management for the network. This type of topology is commonly used in access networks, where a central node is used to aggregate traffic from multiple users or devices, and then forward it to the core network. This design allows for efficient use of resources and easy management of the network.
