FCSS_NST_SE-7.6 · Question #99
Refer to the exhibit, which shows the output of a debug command. What needs to happen for the local router to be elected DR?
The correct answer is D. Both the DR and BDR will have to fail before the local router will be elected DR. On a broadcast network the BDR automatically takes over if the DR dies; only when there is no BDR (or it fails as well) will a new full DR election occur, at which point this router - having the highest router‑ID among the remaining routers - would win.
