With reference to trails and services, which of the following sentences is correct?
- A. Trails are transported over services; that is, trails are clients with respect to services.
- B. A trail can interconnect three ports, while a service always two.
- C. Services are transported over trails; that is, services are clients with respect to trails.
- D. A service is always associated to a single wavelength, while a trail can involve multiple wavelengths.
Answer: C
Explanation:
Services are transported over trails; that is, services are clients with respect to trails. A service is a logical connection that is used to transport data from one point to another. It is created over a trail, which is a physical connection that is established by using multiple wavelengths. As such, services are clients with respect to trails, as they are transported over them.
NEW QUESTION # 24
What is the meaning of first, second, and third window in the optical fiber propagation context?
- A. These windows are three different wavelength intervals where the WDM optical transmission occurs.
- B. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.
- C. Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.
- D. These three windows are three different angles of incidence of the light injected by the laser into the fiber.
Answer: A
Explanation:
In optical fiber propagation context, the first, second, and third window refer to different wavelength intervals where the WDM (Wavelength Division Multiplexing) optical transmission occurs.
The first window is the lowest loss window and is typically in the range of 1300-1324nm. This is the most commonly used window for long-haul communications.
The second window is the 1550 nm window and is the most widely used window for long-haul and ultra-long-haul communications. This window has a lower attenuation than the first window, but it also has more dispersion, which can limit the maximum transmission distance.
The third window is the range of 1625-1675 nm, it is also called the L-band window. This window has lower attenuation than the first and second window but its usage is limited due to the high cost of equipment and lack of commercial devices.
These windows are used in WDM systems to increase the capacity of the fiber by transmitting multiple channels of data at different wavelengths on the same fiber.
A,C,D are not correct as they are not related to the meaning of first, second, and third window in the optical fiber propagation context.

NEW QUESTION # 27
Where can the user set the long-haul WT decoder parameter, when designing a network with EPT?
- A. In the network parameters
- B. In the NE parameters
- C. In the audit menu
- D. In the optimization parameters
Answer: B
Explanation:
The long-haul WT decoder parameter can be set in the NE parameters when designing a network with EPT. This parameter is used to adjust the sensitivity of the decoder and can help to improve the accuracy of the measurements for long-haul WTs.
The Network Element (NE) parameters in EPT (Element Planning Tool) are used to configure various settings and options for the network elements in the network. The long-haul WT decoder parameter is one such setting that can be configured in the NE parameters section. The user can access the NE parameters by navigating to the NE Parameters menu within the EPT interface. The user can then select the appropriate network element and modify the settings as needed. This information can be found in the Nokia guide for EPT.

What is a Shared Risk Group (SRG)?
- A. A set of boards that share the same failure risk
- B. A set of nodes that share a common risk of hardware failure
- C. A set of fibers that share the same latency risk
- D. A set of network resources that share a common failure risk
Answer: D
Explanation:
According to the Nokia Optical Networking documentation, a Shared Risk Group (SRG) is defined as "a set of network resources that share a common failure risk. When a resource in an SRG fails, the other resources in the group are also affected." This can include fibers, boards, nodes, and other network resources. The SRG concept is used in network design and protection mechanisms to ensure survivability and minimal impact on service in case of a failure.
NEW QUESTION # 29
What is a degree-1 node?
- A. A node with only one express channel and therefore made of two sides
- B. A node with one direction only and therefore used as In-Line-Amplifier (ILA)
- C. A node with only one direction and therefore a terminal node
- D. A node with only east and west sides without directions towards north and south
Answer: C
Explanation:
A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.
NEW QUESTION # 30
WDM allows transmission systems to:
- A. Transport multiple signals transparently, onto several wavelengths, all together over one single fiber
- B. Allocate different signals to different time slots
- C. Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission
- D. Increase the bit rate of each client signal by spreading it over multiple wavelengths
Answer: A
Explanation:
WDM (Wavelength Division Multiplexing) allows transmission systems to transport multiple signals transparently, onto several wavelengths, all together over one single fiber. This allows for increased capacity, as many different signals can be transmitted at the same time and along the same fiber. Other advantages include improved signal integrity and reduced signal attenuation.
NEW QUESTION # 31
What is the purpose of the NFM-T node synchronization?
- A. The partial or full node synchronization allows several entities/items defined at node level to be retrieved into the NFM-T database (upload).
- B. The partial or full node synchronization allows several entities/items defined at NFM-T level to be written into the node database (download).
- C. 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).
- D. The partial or full node synchronization allows several entities/items defined at EPT level to be retrieved into the NFM-T database (upload from design).
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.

Designs created with an older release can be opened by a current release but changes cannot be made.
NEW QUESTION # 33
How does a Raman pump work in the 1830 specific implementation?
- A. The amplification is done simultaneously for all channels as they enter the board.
- B. The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.
- C. The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.
- D. As the incoming signal power increase, the gain of the amplifier is reduced.
Answer: B
Explanation:
In Raman amplification, a pump laser is used to excite the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. In the 1830 specific implementation, the pump laser is typically a high-power laser that is launched into the fiber in the opposite direction to the signal. The pump light interacts with the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. This allows the Raman pump to provide a gain that increases with distance, which can be used to compensate for the loss of signal power as it travels through the fiber.
NEW QUESTION # 34
What is the purpose of the validate step in the EPT design process?
- A. During this step, the run design action is triggered for network design consistency check and errors fixing.
- B. During this step, the configuration available on the involved network elements is compared with the design provided by EPT.
- C. This step is used to measure optical power performances over an existing network before making changes.
- D. This step is optional and is useful to verify the network element layout before going through the commission step.
Answer: A
Explanation:
The validate step in the EPT design process is used to trigger the run design action, which is responsible for verifying the consistency of the network design and fixing any errors that may exist. During the validation process, the system will compare the configuration available on the involved network elements and the design provided by EPT, and any discrepancies will be flagged for further investigation or correction.
NEW QUESTION # 35
What is a trail?
- A. A transparent transport of a client signal
- B. An entity to encapsulate a low order signal into a high order container
- C. A link between end points to increase the power budget of the optical link
- D. A physical link between two optical amplifiers
Answer: A
Explanation:
A trail is a transparent transport of a client signal. A trail is a physical link between two points in an optical network, allowing for the transport of a client signal from one point to the other. It is a low-order signal, such as a 10G Ethernet or a Fibre Channel signal, encapsulated into a high-order container, such as a 40G or 100G signal. This allows for the transport of the client signal over longer distances, increasing the power budget of the optical link.
NEW QUESTION # 36
Which of the following are the main reasons for fiber attenuation?
- A. Refraction and reflection
- B. Scattering and absorption
- C. Small channel spacing
- D. Chromatic dispersion (CD) and polarization mode dispersion
Answer: B
Explanation:
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.
