1. Is it possible to mix PSS-24x and PSS-8x shelves In an SWDM configuration?

Yes, as both can be equipped within the same node

No, as they are not compatible and cannot be used within the same node

Yes, but the PSS-24X shelf must be configured as a master

Yes, but the PSS-8X shelf must be configured as a master

2. When monitoring the quality of the received signal in WDM, an open eye indicates:

Low noise

High distortion

High jitter

Presence of high inter-symbolic interference

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

After the amplifiers

Between the mux/demux and the amplifier

Between the transponders and the mux/demux

Before the transponder, on the client side, towards the external device

4. With reference to trails and services, which of the following sentences is correct?

Trails are transported over services; that is, trails are clients with respect to services.

A trail can interconnect three ports, while a service always two.

Services are transported over trails; that is, services are clients with respect to trails.

A service is always associated to a single wavelength, while a trail can involve multiple wavelengths.

5. Which of the following statements is true about chromatic dispersion (CD)?

Different channels have different bandwidth and this causes different CD performances.

The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.

Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.

The fiber attenuation introduces inter-channel interference.

6. Which statement is correct about node synchronization?

Full synchronization retrieves the correlated alarms from the node

Node synchronization is executed to test the reachability of a node

Node synchronization is executed to align the time of the node to the time of the NFM-T platform

Full synchronization retrieves all items from the node (NE parameters.Ports, Alarms, Internal Links,etc)

7. Which of the following is an example of optical protection mechanism?

Optical regeneration (e.g., back-to-back regeneration)

OSNCP (e.g., via Y-cable or OPS card)

GMPLS-enabled SBR

GR and SBR combined

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

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

The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together

The systems are displayed on the CPB panel and they can be individually selected

The systems are not reported on CPB, but only through the Equipment Manager

9. Which statement is correct about the NFM-T network map?

It automatically represents all nodes grouped by the location string assigned during the NE creation.

It represents all supervised nodes grouped by alarm status (with a different color).

It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.

It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.

10. What is a trail?

An entity to encapsulate a low order signal into a high order container

A transparent transport of a client signal

A link between end points to increase the power budget of the optical link

A physical link between two optical amplifiers

11. What is the purpose of the validate step in the EPT design process?

During this step, the configuration available on the involved network elements is compared with the design provided byEP

This step is used to measure optical power performances over an existing network before making changes.

This step is optional and is useful to verify the network element layout before going through the commission step.

During this step, the run design action is triggered for network design consistency check and errors fixing.

12. What is the OAMP LAN interface?

It is an RJ-45 interface (a common Ethernet port) used for cascading 1830 PSS nodes (e.g., external shelves)

It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management

It is an RJ-45 interface (common Ethernet port) used to connect one or more client ports (e.g., 1Gb/s or legacy 100Mbit/s client flows)

It is an RJ-45 interface (a common Ethernet port) used to export active alarms to an external device, typically equipped with several LEDs
