Answers
Suggested answer: B

Explanation:

It can be implemented through the use of a Y-cable or an optical protection switch (OPS) card, which allows for the switching of traffic to a secondary path in the event of a failure on the primary path.

This type of protection is commonly used to protect against fiber cuts and other types of physical layer failures in the optical transport network.

Suggested answer: A

Explanation:

According to the Nokia's 1830 Photonic Service Switch (PSS) product documentation, the Optical Protection Switching (OPS) card is equipped in the transponder and is responsible for providing optical channel protection between the transponder and the amplifiers. The OPS card monitors the optical signal and switches to a pre-configured protection path in case of signal degradation or loss.

D.
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).
Answers
Suggested answer: B

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.

Which statement is correct about node synchronization?

A.
Full synchronization retrieves the correlated alarms from the node
A.
Full synchronization retrieves the correlated alarms from the node

D.
Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)
Answers
Suggested answer: D

Explanation:

Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.

D.
The GMRE activation status is reflected on the color of the icon representing the node
Answers
Suggested answer: C

Explanation:

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.

Answers
Suggested answer: C

Explanation:

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.

Which macro steps can be executed via CPB?

Answers
Suggested answer: A

Explanation:

Node creation, systems validation and system provisioning. The CPB (Commissioning Parameter Builder) application is used to generate commissioning files for a Nokia 1830 Photonic Service Switch (PSS-1) and can be used to create new nodes, validate the system configuration, and provision the system with the appropriate settings and parameters. Power adjustment and generation of system loss report are not related to CPB.

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

A.
The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step

Answers
Suggested answer: C

Explanation:

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.
