Which two statements are true of OSPF stub areas? (Choose two.)

Which type of OSPF area restricts external routes from other areas but allows external routes to be flooded by ASBRs within its own area?

Which area type meets these requirements?

Five routers (R1, R2, R3, R4, and R5) are attached to a single Ethernet LAN and configured with addresses in the same subnet. R1 is chosen as the designated router (DR) and R2 is chosen as the backup designated router (BDR). You add R6 and configure it as shown in the exhibit.
Which routers are now the DR and BDR?

Refer to the Exhibit.

In the exhibit, six routers (R1, R2, R3, R4, R5, and R6) are attached to a single Ethernet LAN and configured with addresses in the same subnet. All devices boot at the same time.

Which router will become the designated router (DR), and which router will become the backup designated router (BDR)?
