The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the graphic.
There is concern that a lack of router resources is impeding internetwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router. Which routers are likely to have been elected as DR? (Choose two.)
A.
Corp-1
B.
Corp-2
C.
Corp-3
D.
Corp-4
E.
Branch-1
F.
Branch-2
A DR is used to redue the amount update overhead that can be caused by OSPF. The election of DR works as follows:
1. Router with highest priority ius the DR. By default all routers have 1 for priority. If that is a tie.
2. It come down to Highest RID.
In scenario it is assume that every router has the priority number, so its going to come down to RID.
A. is incorrect because Corp-4 has higher RID
B. is incorrect because Corp-4 has higher RID
C. is incorrect because Corp-4 has higher RID
E. is incorrect because Branch-2 has higher RID
D. is correct because 10.1.40.40 is highest RID
F. is correct because 10.2.20.20 is Highest RID
i guess ans shld be E and F..
highest ip 10.2.20.20 and 10.2.40.40
