  • Question
  • Which of the following network types have a designated router and a backup designated router assigned?

    1. Broadcast
    2. Point-to-point
    3. NBMA
    4. NBMA point-to-point


  • Options
  • A. 1, 2 and 3
  • B. 1 and 3
  • C. 3 and 4
  • D. All of the above

  • Correct Answer
  • 1 and 3 

    Explanation
    No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-Broadcast Multi-Access (NBMA) network by default.
