John is attempting to connect two computers directly together using the cable he usually uses to connect his computer to his Switch. He has set a Static IP Address on Computer A to 10.10.10.5 with a Subnet Mask of 255.255.255.0. He sets Computer B’s IP Address to 10.10.10.6, with Subnet Mask 255.255.255.0. When he tries to transfer files between the computers, he fails. What is the most-likely reason for this?
John has set the wrong IP Address on both machines.
John needs to change the Subnet Mask on both computers.
John needs to use a crossover cable instead of a straight through cable to connect the computers together.
Two computers cannot be directly connected to each other.
John needs to use a crossover cable instead of a straight through cable to connect the computers together.

What is the difference between a Wireless Router and a Wireless Access Point (WAP)?
There is no difference between the two.
One has an antennae, the other does not.
A Wireless Router is a multifunction device that routes packets, has multiple switch ports on the back, and allows clients to access the Network Wirelessly.
Only approved Wireless devices can connect to a Wireless Access Point, any Wireless device can connect to a Wireless Router.
A Wireless Router is a multifunction device that routes packets, has multiple switch ports on the back, and allows clients to access the Network Wirelessly.
