Question No. 1

What is the purpose of the validate step in the EPT design process?

Show Answer Hide Answer
Correct Answer: D

The validate step in the EPT design process is used to trigger the run design action, which is responsible for verifying the consistency of the network design and fixing any errors that may exist. During the validation process, the system will compare the configuration available on the involved network elements and the design provided by EPT, and any discrepancies will be flagged for further investigation or correction.

What is the metro area network?

Show Answer Hide Answer
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.

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 No. 5

What is a Shared Risk Group (SRG)?

Show Answer Hide Answer
Correct Answer: D

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.
