Question 1

What is the metro area network?

Correct Answer:A
The Metro Area Network (MAN) is a telecommunications network that spans a metropolitan area and connects multiple local area networks (LANs) or business networks together. It typically covers an area that is larger than a LAN but smaller than a wide area network (WAN). The purpose of a MAN is to provide a high-bandwidth, low- latency communication infrastructure for businesses and other organizations in a metropolitan area.

Question 2

Which of the following applications is related to Wavelength Tracker tool?

Correct Answer:B
Tracking the protection path for a specific wavelength. The Wavelength Tracker tool is used to track the protection path of a specific wavelength, allowing the user to quickly identify any issues that may arise and take corrective action.
Wavelength Tracker tool is a feature used to monitor and track the protection path for a specific wavelength in an optical network. It can also be used to monitor and verify the working state of the protection path, and to detect and troubleshoot protection switch events. The Wavelength Tracker tool can be used to monitor the protection path for a specific wavelength, and it can also be used to trace the end-to-end path of a wavelength through the network. This tool is typically used by network operators to monitor and troubleshoot wavelength-level issues in the network, such as protection switch events or wavelength-level performance issues.

Question 3

Is it possible to select the fiber type independently for each segment while designing a network in EPT?

Correct Answer:D
Yes, during the segment creation phase or editing. It is possible to select the fiber type independently for each segment while designing a network in EPT. This can be done during the segment creation phase or when editing an existing segment. This allows for more flexibility when designing the network and allows for more efficient use of resources.

Question 4

When monitoring the quality of the received signal in WDM, an open eye indicates:

Correct Answer:A
An open eye pattern indicates that the signal is not affected by noise, and the received signal is of high quality. This is because an open eye pattern is the result of a signal that is aligned in time, and is not affected by noise or other distortions.

Question 5

Which of the following statements is true?

Correct Answer:A
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.
