Nokia Optical Networking Fundamentals 認定 4A0-205 試験問題 (Q18-Q23):

質問 # 18
With reference to the image, where is the OPS card placed to provide the OMSP protection?

A. Between the transponders and the mux/demux
B. After the amplifiers
C. Between the mux/demux and the amplifier
D. Before the transponder, on the client side, towards the external device

正解：D

質問 # 19
In which window(s) does the attenuation reach its minimum peak?

A. Second window (1300 nm)
B. Both first and second windows
C. First window (850 nm)
D. Third window (1550 nm)

正解：D

解説：
The third window (1550 nm) is where the attenuation reaches its minimum peak. This is because the materials used in fiber optic cables have minimal absorption in this wavelength range. The first and second windows (850 nm and 1300 nm respectively) have higher attenuation due to the materials used in the fiber optic cables.

質問 # 20
Is it possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation?

A. Only designs created with current and older releases can be opened and edited.
B. No restrictions are imposed on the software release.
C. Designs created with an older release can be opened by a current release but cannot make changes.
D. Only designs created with the current release can be opened and edited.

正解：A

解説：
It is possible to open and manage EPT designs that are created with different releases than the release installed on the local workstation, however 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 changes cannot be made.

質問 # 21
By using the EPT run design command, are the previously designed elements removed?

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

正解：D

解説：
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).

質問 # 22
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?

A. It represents the ability to drop any lambda from any Add/Drop block port.
B. It represents the ability to reroute lambdas to any direction.
C. It represents the ability to drop the same wavelength from different degrees.
D. It represents the ability to support the Fixed Grid standard.

正解：C

解説：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The term CDC-F stands for Colorless, Directionless, Contentionless, and Flex-grid. While "Colorless" allows any wavelength on any port and "Directionless" allows any port to be routed to any output fiber (degree), Contentionless solves a specific physical limitation of traditional multiplexers. In a standard ROADM, you cannot drop the same wavelength (e.g., Channel 21) from two different directions (e.g., North and West) into the same add/drop structure because they would "contend" or collide on the same internal fiber.
A Contentionless architecture (typically utilizing a Multicast Switch or MCS) allows the node to drop the same wavelength from different degrees simultaneously without interference. This is critical for high-availability mesh networks where a single transponder might need to receive a specific wavelength from a primary path and a backup path. Without contentionless capabilities, operators would have to carefully manage wavelength assignments across the entire network to ensure no two identical frequencies ever meet at the same drop structure, which significantly complicates planning and restoration.
