Dell EMC Specialist – Systems Administrator, VNX — Question 24

Which type of protocol is OSPF and what metric does it use to determine best path?

Answer options

• A. Link-state protocol that uses a concept of cost as metric
• B. Hybrid protocol that uses hop count as a metric
• C. Path vector protocol that uses the Dijkstra algorithm as a metric
• D. Distance Vector protocol that uses bandwidth and delay as metric

Correct answer: A

Explanation

OSPF is classified as a link-state protocol, which means it maintains a complete view of the network topology and utilizes a cost metric based on link bandwidth to determine the best path. The other options are incorrect as they describe different types of protocols or metrics that do not apply to OSPF.
