Wireless controller Question 6: You have been put in charge of connecting two company networks that were previously separated.You need to connect a 100BaseTx Ethernet network with an older token ring network. Most traffic will be localized within each network, with only a little traffic crossing between networks.Both networks are using the TCP/IP protocol suite.Which connectivity device would be the best choice in this situation?

Answer:

Router Question 7: A technician is replacing a SOHO router and has configured DHCP to assign private IP addresses to hosts on the local network. These hosts can communicate with each other, but users can't browse the internet.Which of the following changes to the SOHO router is most likely to restore internet connectivity?

Answer:

Configure the SOHO router for NAT.

Question 8: Consider the network shown.

When you run the show interfaces command on Switch1, you observe a significant number of runts on the Gi0/1 interface.What does this statistic indicate?

Answer:

Collisions are occurring.Question 9: You need to view the type of serial cable that has been used on the s0/0/1 interface and which end of the cable is connected to the DCE or DTE.Which command should you use to do this?
