Selected Answer: A
R1 was initially elected as the DR because they would have the same priority by default (1). The next step in the election process would be the highest IP address which R1 has over R2. Thus, setting the priority of R2 to 100 would elect it as DR. The highest priority wins for DR once it is within scope.

Selected Answer: A
B. R2's new router ID 192.168.2.7 is still lower than R1's 192.168.2.8 C. R2's new router ID 10.100.100.100 is still lower than R1's 192.168.2.8 D. The OPSF priority is 1 by default, all routers have the same.

R1 is elected because the highest ID, so if change ID on R2 on higher it will be elected as DR. so C is correct. Moreover there is a spelling mistake in A.

simple. you must specify a priority that is higher (thus lower) than the default 90 of OSPF; then you use priority 100

You are making a mistake , my friend. AD has nothing to do with priority.

do you mean the administrative distance? the ad of ospf is 110. eigrp is 90. the port of ospf is 89, but i dont think that is considered in the answer
