Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 300

Given the following partial configuration for Router A:
interface serial 0
ip address 10.1.1.1 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
router ospf 7
network 10.1.1.0 0.0.0.255 area 0
Which two statements are correct? (Choose two.)

Answer options

• A. DR/BDR elections do not take place.
• B. The area 0 NBMA cloud is configured as more than one subnet.
• C. The router is restricted to a hub and spoke topology.

Correct answer: O, S, P, F

Explanation

Option A is correct because in a point-to-multipoint configuration, DR and BDR elections are not necessary. Option C is also correct, as point-to-multipoint configurations typically operate in a hub-and-spoke topology, meaning that traffic flows through a central hub to reach all spokes. Option B is incorrect since the configuration indicates a single subnet (10.1.1.0/24) for the area 0 NBMA cloud.
