NEW QUESTION # 34
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. It depends, the user is prompted to choose whether to delete or leave the previously designed elements.
- D. 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).
Answer: C
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 # 36
Which of the following statements is true?
- A. Logs report both active and historical events.
- B. Alarms and conditions report only historical status of the node.
- C. Alarms and conditions report a real time status of the node.
- D. Logs report a real time status of the node.
Answer: A
Explanation:
A log is a record of events that have occurred within a system, such as a network device or an application. Logs can include information about system activity, configuration changes, and error messages. They can be used for troubleshooting, auditing, and compliance purposes. Logs can report both active (real-time) and historical events that have occurred within a system.
Alarms and conditions, on the other hand, are used to notify operators of real-time status of the node, such as when a threshold is breached or when a specific event occurs. Alarms and conditions are typically used to provide real-time notifications of potential problems or issues, while logs are used to provide a historical record of what has occurred.
NEW QUESTION # 37
What is a trail?
- A. A physical link between two optical amplifiers
- 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 transparent transport of a client signal
Answer: D
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 # 38
Which of the following are the main reasons for fiber attenuation?
- A. Refraction and reflection
- B. Small channel spacing
- C. Scattering and absorption
- D. Chromatic dispersion (CD) and polarization mode dispersion
Answer: C
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.
