Question 7

Which application generates the commissioning file(s)?

A. NFM-T

B. NSP

C. CPB

D. EPT

Correct Answer:C
The CPB (Commissioning Parameter Builder) application is used to generate the commissioning files for a Nokia 1830 Photonic Service Switch (PSS-1). The CPB application allows the user to create multiple commissioning files [1][2], which can be used to configure a variety of different features on the device. The CPB also allows users to view, edit and modify the commissioning files before they are uploaded to the device. The NSP (Network Service Platform) and EPT (Element Provisioning Tool) are used to manage the devices and network elements within the network, but do not generate commissioning files.

Question 8

How is it possible to check the activation status of GMRE on a node?

A. The GMRE reachability can be tested via ping request from NFM-T

B. The ControlPlane status column on the node list displays the GMRE status for the selected node

C. The GMRE activation status is reported in the supervision state column on the node list

D. The GMRE activation status is reflected on the color of the icon representing the node

Correct Answer:C
The GMRE activation status is reported in the supervision state column on the node list. The supervision state column displays the GMRE status of the node, which is either "Activated" or "Not Activated". This allows the user to quickly check the GMRE activation status of a node without having to ping the node from the NFM-T platform.

Question 9

Which sentence about NFM-T is correct?

A. 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

B. NFM-T fully supports optical and IP nodes

C. NFM-T is used to design and manage optical network

D. NFM-T is used to provision optical services havingIP nodes as extremities

Correct Answer:D
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.

Question 10

Which mechanisms can be put in place to increase network survivability?

A. Protection, where backup resources are pre-allocated and reserved; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism

B. Protection, where backup resources are allocated upon failure; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism

C. Protection, where backup resources are allocated upon failure; or restoration, where backup resources are pre-allocated and reserved

D. Protection, where backup resources are pre-allocated and reserved; or restoration, where backup resources are allocated upon failure.

Correct Answer:D
There are two main mechanisms that can be put in place to increase network survivability: protection and restoration. Protection involves pre-allocating and reserving backup resources so that they are ready in case of a failure. Restoration involves allocating backup resources upon failure and using a 1+1 protection mechanism to recover each trail. This ensures that the network is able to re-route traffic in the event of a failure, increasing the overall survivability of the network.

Question 11

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

A. Only designs created with the current release can be opened and edited.

B. Only designs created with current and older releases can be opened and edited.

C. Designs created with an older release can be opened by a current release but cannot make changes.

D. No restrictions are imposed on the software release.

Correct Answer:B
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.

Question 12

What is a Shared Risk Group (SRG)?

A. A set of fibers that share the same latency risk

B. A set of boards that share the same failure risk

C. A set of nodes that share a common risk of hardware failure

D. A set of network resources that share a common failure risk

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.
