ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 4

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.)

Answer options

• A. Corp-1
• B. Corp-2
• C. Corp-3
• D. Corp-4
• E. Branch-1
• F. Branch-2

Correct answer: D, F

Explanation

The routers elected as DR typically have the highest OSPF priority, and when priorities are equal, the router with the highest router ID is selected. In this case, Corp-4 and Branch-2 likely have the highest router IDs among the options, leading to their election as DRs, whereas the others do not meet that criterion.
