Cisco CCNA mock exam questions sample test – Question 117

.You and your team are evaluating the use of OSPFv3 in your IPv6 network.
Which of the following statements is true of OSPFv3?

A. There will be a higher demand on the processor to run the link-state routing algorithm
B. Router IDs must match for adjacency formation
C. Area IDs do not need to match for adjacency formation
D. Area types do not need to match for adjacency formation

Correct Answer: A

Explanation:
There will be a higher demand on the processor to run the link-state routing algorithm. As with OSPFv2, OSPFv3 uses the Shortest Path first (SPF) algorithm, which is processor
intensive. It is one of the only downsides of using the algorithm.
OSPFv3 also shares a number of other characteristics with its v2 counterpart with respect to adjacency formation. For example:
Router IDs should not match.
Router IDs should reflect the correct router ID for each device.
Area IDs must match.
Area types must match.
Objective:
Routing Fundamentals
Sub-Objective:
Configure, verify, and troubleshoot single area and multi-area OSPFv3 for IPv6 (excluding authentication, filtering, manual summarization, redistribution, stub, virtual-link, and LSAs)
