Which of the following statements is true about the OSPF DR?
Which of the following statements is true about the OSPF DR?
If the priority of an interface is 0, the device where the interface resides cannot become the DR. In OSPF (Open Shortest Path First) networks, the election process for the Designated Router (DR) involves several factors, including interface priority and router ID. A device with an interface priority of 0 is not eligible to become the DR, which means it will not participate in the election process for DR. The other statements are either incorrect or not comprehensive.
D is correct
Correct. While A is partially correct, if there is a tie on the router priority. Then the highest router ID is selected as the DR. So potentially both are needed to decide the DR. While if the priority if an interface is 0, the device where the interface is connected to (resides) cannot become the DR!
Option A is correct
Highest priority win
D is more complete
