Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 45

Which of the following are features of the OSPF protocol?

Answer options

• A. Routing loops are likely to occur.
• B. Triggered update is supported.
• C. The shortest path is calculated based on the number of hops.
• D. Area division is supported.

Correct answer: D

Explanation

Option D is correct because OSPF supports area division, which helps in managing routing efficiently. Option A is incorrect as OSPF is designed to prevent routing loops. Option B is misleading, as while OSPF does support triggered updates, it is not a primary feature. Option C is not accurate since OSPF calculates the shortest path using the Dijkstra algorithm, which considers metrics beyond just hop count.
