QUESTION 18
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

QUESTION 19
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.

QUESTION 20
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

QUESTION 21
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.

QUESTION 22
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

QUESTION 23
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.

QUESTION 24
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.

QUESTION 25
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

QUESTION 26
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).

QUESTION 27
In which of the following forms does the TTI byte provide information on network elements?

Source (SAPI) and Destination (DAPI) Access Point Identifiers

Source and destination IP addresses and overhead

Source and destination MAC addresses

Source and destination time-slot identifiers

QUESTION 28
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)

QUESTION 29
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.

QUESTION 30
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

QUESTION 31
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

QUESTION 32
A user needs to retrieve the active alarm list from a network element. Which command should be issued through an 1830 PSS CLI?

alm

display alarms

show active alarms

retrieve alarms

QUESTION 33
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?

Tracing a service along an optical path.

Testing a node’s internal fiber connectivity before service provisioning.

Performing channel power monitoring.

Detecting unexpected or missing channels.

QUESTION 34
What is the definition of OSNR?

The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber including both signal and optical noise.

The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.

The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.

The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.

QUESTION 35
Which use case is most suitable for the deployment of a star topology?

Access networks, for collecting traffic towards the main central node

ASON networks, to protect traffic via GMPL5 protocols

Backbone networks, for supporting protection routes

SNCP-protected links

QUESTION 36
What is the metro area network?

The metro area network is that portion of network that passes through a city to provide connections to several customers.

The metro area network is located between access and core domains.

The metro area network is made of OCS/SWDM nodes only, as no pure photonic nodes are used here.

The metro area network is located in between two access area networks and made of photonic nodes only (no OCS/SWDM nodes are used there).
