12.网络管理员在AR G3系列路由器上使用ping命令来测试到达10.0.0.2的连通性,下面关于输出描述正确的是()。
PING 10.0.0.2: 800 data bytes, press CTRL_C to break
Reply from 10.0.0.2: bytes=800 Sequence=1 ttl=255 time=40 ms
Reply from 10.0.0.2: bytes=800 Sequence=2 ttl=255 time=30 ms
- 10.0.0.2 ping statistics ---
2 packet(s) transmitted
2 packet(s) received
0.00% packet loss
round-trip min/avg/max = 30/35/40 ms
