Nokia Optical Networking Fundamentals Sample Questions (Q39-Q44):

NEW QUESTION # 39
What is a Shared Risk Group (SRG)?

A. A set of fibers that share the same latency risk
B. A set of boards that share the same failure risk
C. A set of network resources that share a common failure risk
D. A set of nodes that share a common risk of hardware failure

Answer: C

Explanation:
According to the Nokia Optical Networking documentation, a Shared Risk Group (SRG) is defined as "a set of network resources that share a common failure risk. When a resource in an SRG fails, the other resources in the group are also affected." This can include fibers, boards, nodes, and other network resources. The SRG concept is used in network design and protection mechanisms to ensure survivability and minimal impact on service in case of a failure.

NEW QUESTION # 40
How are the EPT systems related to NFM-T when CPB is performed?

A. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together
B. The systems are displayed on the CPB panel and they can be individually selected
C. The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step
D. The systems are not reported on CPB, but only through the Equipment Manager

Answer: B

Explanation:
The EPT systems are displayed on the CPB (Commissioning Parameter Builder) panel and they can be individually selected. This allows the user to configure the network elements in the network and provision them according to their specific requirements. The systems are not reported on CPB, but through the Equipment Manager. The Equipment Manager is the interface used to configure the network elements and the EPT systems. The NFM-T is not related to the CPB and does not affect the CPB process.

NEW QUESTION # 41
Which of the following statements is true?

A. Logs report both active and historical events.
B. Logs report a real time status of the node.
C. Alarms and conditions report a real time status of the node.
D. Alarms and conditions report only historical 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 # 42
Which statement is correct about the NFM-T network map?

A. It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.
B. It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.
C. It represents all supervised nodes grouped by alarm status (with a different color).
D. It automatically represents all nodes grouped by the location string assigned during the NE creation.

Answer: A

Explanation:
The NFM-T network map provides a graphical view of the network with different colors used to represent each node, physical connection, and active alarm. It allows the user to quickly identify any issues in the network and provides context sensitive navigation.

NEW QUESTION # 43
With reference to trails and services, which of the following sentences is correct?

A. Services are transported over trails; that is, services are clients with respect to trails.
B. Trails are transported over services; that is, trails are clients with respect to services.
C. A service is always associated to a single wavelength, while a trail can involve multiple wavelengths.
D. A trail can interconnect three ports, while a service always two.

Answer: A

Explanation:
Services are transported over trails; that is, services are clients with respect to trails. A service is a logical connection that is used to transport data from one point to another. It is created over a trail, which is a physical connection that is established by using multiple wavelengths. As such, services are clients with respect to trails, as they are transported over them.
