Nokia Optical Networking Fundamentals 4A0-205 Prüfungsfragen mit Lösungen
Frage #1
Which statement is correct about node synchronization?
- A. Node synchronization is executed to test the reachability of a node
- B. Node synchronization is executed to align the time of the node to the time of the NFM-T platform
- C. Full synchronization retrieves the correlated alarms from the node
- D. Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)
Antwort: D 🗳️

Frage #2
What is the function of a pre-amplifier in an optical network?
- A. Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.
- B. Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.
- C. Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.
- D. Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.

Frage #3
Which of the following statements best describes the definition of PCT?
- A. A tool to validate internal fiber connectivity on CDC-F 2.0 nodes.
- B. A tool supporting external links autodiscovery on NFM-T.
- C. A tool supporting zero-touch power management on PSS-32 equipment.
- D. A tool supporting nodes' automatic provisioning on NFM-T.

Frage #4
Which of the following statements is true about chromatic dispersion (CD)?
- A. Different channels have different bandwidth and this causes different CD performances.
- B. The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.
- C. Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.
- D. The fiber attenuation introduces inter-channel interference.

- A. Logs report a real time status of the node.
- B. Alarms and conditions report only historical status of the node.
- C. Logs report both active and historical events.
- D. Alarms and conditions report a real time status of the node.
