Question 101
As shown in the figure, there are 4 ways to divide the OSPF area, which one is correct? (multiple choice)


Question 102
The two empty-configured MSR routers are connected as shown in the figure. By configuring the IP address, the GE0/0 interfaces of the two routers can communicate with each other.

Now the following configurations are added to the two routers respectively:
RTA:
[RTA]ospf
[RTA-ospf-1]area 0
[RTA-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTA-GigabitEthernet0/0]ospf dr-priority 2
RTB:
[RTB]ospf [RTB-ospf-1]area 0
[RTB-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTB-GigabitEthernet0/0]ospf dr-priority
Then after the OSPF neighbor status is stable, ______.
