Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?
- A. In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
- B. In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.
- C. In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

What can you deduce from the show command on router R6?
- A. The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.
- B. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.
- C. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3.
- D. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.
