In the following figure, all links are Ethernet links, and all interfaces on the routers are running OSPF. Given this, how many DRs will be elected on this network?

The correct answer is B. 2. On a network consisting of multiple broadcast domains (like Ethernet links), OSPF will elect one DR (Designated Router) and one BDR (Backup Designated Router) per broadcast segment. In this topology, two Ethernet segments are formed, so two DRs will be elected.
