質問 1：
On the network shown in the figure, single-hop BFD is configured on R1 and R2 .
A network engineer finds that the BFD session goes down . To locate the fault, the network engineer queries the BFD configurations on R1 and R2 .
According to the configuration information marked in the figure, it can be determined that mismatched time parameter settings on R1 and R2 cause the BFD session to go down .
Is this statement TRUE or FALSE ?
A. TRUE
B. FALSE
正解：B

質問 2：
A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled and function as the gateways of PC1 and PC2, respectively .
Given this, which of the following statements are true?
Network Topology:

* Interface GE0/0/1 : 192.168.1.1/24 (Gateway for PC1)
R2:
* Interface GE0/0/0 : 10.0.12.2/24 (Connected to R1)
* Interface GE0/0/1 : 192.168.1.2/24 (Gateway for PC2)
