2222. You have a server with two NICs, each attached to a different IP network. You’re having problems communicating with devices on remote networks that send packets to one of the interfaces. The server receives the packets fine, but the server’s replies never reach the intended destination network. Replies to packets that come in through the other interface seem to reach their destination without any problems. What can you do that will most likely solve the problem?
- Ab. Change the default gateway to use the router that’s on the network of the interface exhibiting problems.
- Ba. Configure a second default gateway on the interface exhibiting problems.
- Cc. Use the route command to add routes to the networks that aren’t receiving replies.
- Dd. Replace the NIC that’s having problems replying to packets.

Now when you try the command ping computer5 from your workstation, you don’t get a successful reply. Other computers on the network aren’t having a problem communicating with the computer. Which command might help solve the problem?
- Aa. arp -d
- Bb. ipconfig /flushdns
- Cc. tracert computer5
- Dd. ping -6 172.31.1.110
