It is used to create new network instances, such as physical connections, infrastructures and services.

Q33. 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

Q34. What is the block that converts the colorless (or black and white) client signal to a specific optical channel in a WDM system?

Wavelength router (WR)

Optical transponder (OT)

Static filter device (SFD)

Dispersion compensation module (DCM)

Q35. WDM allows transmission systems to:

Transport multiple signals transparently, onto several wavelengths, all together over one single fiber

Increase the bit rate of each client signal by spreading it over multiple wavelengths

Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission

Allocate different signals to different time slots

Q36. With reference to the power budget, what is the meaning of receiver dynamic range?

It is the minimum power to be received for a given BER.

It is the range between the receiver overload power and its sensitivity.

It is the range between the maximum transmit power and the minimum transmit power.

It is the maximum receiver power to prevent an overload.

Q37. Which of the following statements is true?

Logs report both active and historical events.

Alarms and conditions report a real time status of the node.

Alarms and conditions report only historical status of the node.

Logs report a real time status of the node.

Q38. What is the function of a pre-amplifier in an optical network?

Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.

Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.

Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.

Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.

Q39. Which type of ports are present in the Colorless Wavelength Router (CWR)?

Colorless uni-directional ports only

Black and white ports

Colorless bi-directional ports

DeMux ports

Q40. Is it possible to select the fiber type independently for each segment while designing a network in EPT?

Yes, during the link creation through the wizard

No, a unique type is allowed per design for all segments

No, as the fiber type is selected for links only and it’s one for whole design

Yes, during the segment creation phase or editing

Q41. 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

Q42. A user needs to check for interface details against the commands is the correct one?

config interface detail 1/17/L1

config card 11star1a interface 1/17 detail

show interface 11starla 1/17/L1 detail

11starla 1/17 port-detail

Q43. Which mechanisms can be put in place to increase network survivability?

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

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

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

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

Q44. Is it possible to modify node parameters within the edit EPT menu?

Yes, the user can apply manual changes directly from this view

Yes, but the user can modify only the node name and location

No, this view is used to display a close-up view of the node

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

Q45. What is an optical switch?

A device that selectively transfers an optical signal from one port to another.

A device that groups multiple lambdas in one multiplexed signal.

A device that selectively transfers an optical ODU frame from one port to another.

A device that converts optical signal to electrical to allow switching through the electrical matrix, and then again to optical towards the next card (and versa).

Q46. Which of the following applications is related to Wavelength Tracker tool?

Collecting logs related to possible issue affecting a wavelength path

Tracking the protection path for a specific wavelength

Tracing the end-to-end wavelength optical power

Correcting errors related to wavelength inconsistencies

Q47. By using the EPT run design command, are the previously designed elements removed?

Yes, they are but only the first time the command is launched as – for future design phases – the existing packs need to keep the same slotting.

It depends, the user is prompted to choose whether to delete or leave the previously designed elements.

Not the design is always progressive, on top of the previous design.

Yes, although this is not happening in case of GMPLS-enabled nodes because existing slots cannot change as they are controlled by another manager (GMRE).

Q48. In which window(s) does the attenuation reach its minimum peak?

First window (850 nm)

Second window (1300 nm)

Third window (1550 nm)

Both first and second windows

Q49. How does a Raman pump work in the 1830 specific implementation?

The amplification is done simultaneously for all channels as they enter the board.

As the incoming signal power increase, the gain of the amplifier is reduced.

The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.

The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.

Q50. Which application generates the commissioning file(s)?

NFM-T

NSP

CPB

EPT

Q51. Where can the user set the long-haul WT decoder parameter, when designing a network with EPT?

In the network parameters

In the optimization parameters

In the NE parameters

In the audit menu

Q52. What is the meaning of first, second, and third window in the optical fiber propagation context?

These windows correspond to three different minimum and maximum optical power levels used for optical transmission.

These windows are three different wavelength intervals where the WDM optical transmission occurs.

These three windows are three different angles of incidence of the light injected by the laser into the fiber.

Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.
