Which application generates the commissioning file(s)?

1. A. NFM-T
2. B. NSP
3. C. CPB
4. 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.

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

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

Correct Answer: D
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.

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

1. A. The GMRE reachability can be tested via ping request from NFM-T
2. B. The ControlPlane status column on the node list displays the GMRE status for the selected node
3. C. The GMRE activation status is reported in the supervision state column on the node list
4. 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.

How are the EPT systems related to NFM-T when CPB is performed?

1. A. The systems are not reported on CPB, as this Is transparent to the user and the wholenetwork is validated and provisioned in one step
2. B. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together
3. C. The systems are displayed on the CPB panel and they can be individually selected
4. D. The systems are not reported on CPB, but only through the Equipment Manager

Correct Answer: C
The EPT systems are displayed on the CPB (Commissioning Parameter Builder) panel and they can be individually selected. This allows the user to configure the network elements in the network and provision them according to their specific requirements. The systems are not reported on CPB, but through the Equipment Manager. The Equipment Manager is the interface used to configure the network elements and the EPT systems. The NFM-T is not related to the CPB and does not affect the CPB process.

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

1. 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
2. B. Protection, where backup resources are allocated upon failure; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism
3. C. Protection, where backup resources are allocated upon failure; or restoration, where backup resources are pre-allocated and reserved
4. 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.
