Nokia Certified Network Associate – Data Center — Question 39

To create a flex-algo instance in a network, which of the following configuration steps is mandatory?

Answer options

• A. Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.
• B. Configuring at least one router in the network to create and advertise the flex-algo definition.
• C. Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).
• D. Configuring LSPs between every pair of PE routers.

Correct answer: B

Explanation

The correct answer is B because at least one router must be configured to create and advertise the flex-algo definition for it to function in the network. Options A, C, and D, while important for various aspects of flex-algo, are not mandatory steps for creating the initial instance.
