Exam 350-601 topic 1 question 24 discussion

The correct answer is A. A = 255 is the highest router priority B = It is the same (as we are doing nothing) C = Is not the highest router ID D = Ineligible to become the DR/BDR

Key points about OSPF priority 0: No DR election participation: When a router has a priority of 0, it will not be considered during the DR election process. Default priority is 1: The standard OSPF priority value for a router interface is usually set to 1. Higher priority means higher chance of becoming DR: A router with a higher priority value is more likely to be elected as the DR. Impact on network design:

A is correct!

A is correct. Priority in OSPF is mainly used to influence/determine a designated router/backup designated router for a network. By default, the priority is 1 on all routers. A router with a high priority will always win the DR/BDR election process. If there is a tie, a router with the highest router ID wins the election. The router with the second highest OSPF priority or router ID will become a BDR.
