Which OSPF network type requires the election of a DR/BDR?

point-to-multipoint nonbroadcast

In an ospf hub-and-spoke topology, what needs to be done to ensure that the spoke routers would never be selected as DR and BDR?

all spoke routers need to be configured with an OSPF interface priority of 0 (ip ospf priority) so that they will not become the DR/BDR

because non-broadcast networks do not elect a DR/BDR, nothing needs to be done.

all routers must be configured with an OSPF interface priority of 0 (ip ospf priority) to disable the DR/BDR election process

on of the spoke routers will need to be configured as the DR by setting the OSPF interface priority higher than 1 (ip ospf priority)
