Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 61

Which of the following statements is true about the OSPF DR?

Answer options

• A. The DR must be the device with the highest priority on the network.
• B. The DR is elected in preemption mode.
• C. A router with a larger router ID is elected as the DR.
• D. If the priority of an interface is 0, the device where the interface resides cannot become the DR.

Correct answer: C

Explanation

Option C is correct because in OSPF, the router with the highest router ID is chosen as the DR if there is a tie in priority. Option A is misleading since the DR is not solely determined by priority, and B is incorrect as OSPF does not use preemption for DR election. Option D is accurate in stating that a priority of 0 means the router cannot become the DR, but it does not address the election criteria directly.
