Q
Which of the situations might not require multiple routing protocols in a network?
AA. When a new layer 2-only switch is added to the network
BB. When you are migrating from one routing protocol to another
CC. When you are using routers from multiple vendors
DD. When there are host-based routers from multiple vendors
Correct Answer:
A. A. When a new layer 2-only switch is added to the network
Explanation:
Multiple routing protocols are required only when we need to migrate from one routing protocol to another, or when we are using routers from multiple vendors, or when there are host-based routers from multiple vendors. Routing is not a layer-2 function so we don’t require multiple routing protocols when new layer-2 switch is added.
