解释一下:这个题是需要根据图中的信息来判断接口的类型。可以看到接口的MAC地址,表示这个接口肯定不是串行接口,所以可以排除D和E的选项。看带宽BW 100000 Kbit,表示的是100M的带宽,所以这是个Fast Ethernet接口。
38. On point-to-point networks, OSPF hello packets are addressed to which address?
39.While troubleshooting a connectivity problem, a network istrator notices that a port status LED on a Cisco Catalyst series switch is alternating green and amber. Which condition could this indicate?
A. The port is experiencing errors.
B. The port is istratively disabled.
C. The port is blocked by spanning tree.
D. The port has an active link with normal traffic activity.
40. Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network has converged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goes down. In which two ways will the routers in this network respond to this change? (Choose two.)
A. All routers will reference their topology database to determine if any routes to the 192.168.1.0 network are known.
B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire.
C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous
