Nokia Optical Networking Fundamentals Sample Questions (Q47-Q52):

NEW QUESTION # 47
By using the EPT run design command, are the previously designed elements removed?

A. It depends, the user is prompted to choose whether to delete or leave the previously designed elements.
B. Not the design is always progressive, on top of the previous design.
C. 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).
D. 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.

Answer: A

Explanation:
The EPT run design command can remove previously designed elements, but the user is prompted to choose whether to delete them or leave them intact. This allows the user to progress their design while still keeping the existing elements in place. If the user selects to leave the existing elements, then they will remain in the same slots. If GMPLS nodes are used, the existing slots cannot change as they are controlled by another manager (GMRE).

NEW QUESTION # 48
Which type of ports are present in the Colorless Wavelength Router (CWR)?

A. DeMux ports
B. Colorless uni-directional ports only
C. Colorless bi-directional ports
D. Black and white ports

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Nokia 1830 PSS (Photonic Service Switch) architecture, the Colorless Wavelength Router (CWR) is a specialized module used within ROADM nodes to enable "colorless" add/drop capabilities. Traditional static multiplexers, like the SFD (Static Filter Device), use fixed-wavelength ports where a specific port is hard-wired to a specific frequency (color). In contrast, a CWR allows any wavelength to be added or dropped from any of its ports.
The ports on a CWR are bi-directional. This means that a single physical port on the CWR card handles both the transmit (Tx) and receive (Rx) paths for a specific wavelength, typically connecting to a transponder's line-side interface. This bi-directional design simplifies fiber management within the shelf and is a key requirement for the "Colorless" attribute of modern flexible grids. By utilizing CWR modules, operators can remotely retune a transponder to a different frequency without needing a technician to physically move fiber patches to a different port on a multiplexer, significantly increasing operational efficiency and reducing human error during service provisioning or restoration.

NEW QUESTION # 49
Which macro steps can be executed via CPB?

A. Power adjustment and generation of the system loss report
B. Systems validation, system provisioning, power adjustment
C. Node creation, systems validation and system provisioning
D. Node supervision, system validation and system provision

Answer: C

Explanation:
Node creation, systems validation and system provisioning. The CPB (Commissioning Parameter Builder) application is used to generate commissioning files for a Nokia 1830 Photonic Service Switch (PSS-1) and can be used to create new nodes, validate the system configuration, and provision the system with the appropriate settings and parameters. Power adjustment and generation of system loss report are not related to CPB.

NEW QUESTION # 50
How does a Raman pump work in the 1830 specific implementation?

A. The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.
B. The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.
C. As the incoming signal power increase, the gain of the amplifier is reduced.
D. The amplification is done simultaneously for all channels as they enter the board.

Answer: A

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 # 51
Which statement is correct about node synchronization?

A. Node synchronization is executed to align the time of the node to the time of the NFM-T platform
B. Node synchronization is executed to test the reachability of a node
C. Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)
D. Full synchronization retrieves the correlated alarms from the node

Answer: C

Explanation:
Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.
