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. 3. In OSPF networks, a DR (Designated Router) is elected for each broadcast domain, such as each Ethernet segment. Given the topology where there are multiple Ethernet segments, a DR will be elected in each segment, resulting in three DRs based on the configuration and network
