Q15. 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).

Q16. 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

Q17. What is a degree-1 node?

A node with only one direction and therefore a terminal node

A node with only one express channel and therefore made of two sides

A node with only east and west sides without directions towards north and south

A node with one direction only and therefore used as In-Line-Amplifier (ILA)

Q18. Is it possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation?

Only designs created with the current release can be opened and edited.

Only designs created with current and older releases can be opened and edited.

Designs created with an older release can be opened by a current release but cannot make changes.

No restrictions are imposed on the software release.

Q19. 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

Q20. 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.

Q21. Which macro steps can be executed via CPB?

Node creation, systems validation and system provisioning

Power adjustment and generation of the system loss report

Systems validation, system provisioning, power adjustment

Node supervision, system validation and system provision

Q22. Which of the following are the main reasons for fiber attenuation?

Refraction and reflection

Scattering and absorption

Chromatic dispersion (CD) and polarization mode dispersion

Small channel spacing

Q23. 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

Q24. 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.

Q25. 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.

Q26. A user needs to check for interface details against the commands is the correct one?

show interface 11starla 1/17/L1 detail

config card 11star1a interface 1/17 detail

11starla 1/17 port-detail

config interface detail 1/17/L1

Q27. 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

Q28. 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

Q29. 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
