質問 4

The following routing information is seen on the MSR router running RIP:
<MSR>display ip routing-table 6.6.6.6
Routing Table: Public
Summary Count: 2
Destination/Mask Proto Pre Cost NextHop Interface
6.0.0.0/8 RIP 100 1 100.1.1.1 GE0/0
6.6.6.0/24 Static 60 0 100.1.1.1 GE0/0

（A）The packet will first match the RIP route in the routing table because its mask is the shortest

（B）The packet will preferentially match the static route in the routing table because its metric value is the smallest

（C）The packet will first match the static route in the routing table because of its high priority

（D）The packet will preferentially match the static route in the routing table because it has the longest mask

質問 10

There are two hops from the source device to the destination device. Use the tracert command to detect the path. When detecting the first hop, the source device sends a UDP packet with a TTL of 1 to the middle hop; when detecting the second hop, the source device sends a UDP packet with a TTL of 2, and the packet reaches the middle hop first, and the TTL is decremented When the message reaches the destination, the TTL will be decremented to 0. At this time, the destination device will send an ICMP_____ message to the source to inform the source device that it has tracked the destination address.

（A）Echo Request

（B）Echo Reply

（C）Time Exceeded

（D）Port Unreachable
