Lots of networking-specific questions, but pretty fundamental in nature. Here are some: How would you determine if a computer was on the network? What utility would show you how long it takes from one internal computer to get to another internal computer? What is DHCP? What’s the difference between a hub and a switch? What is a default gateway? How would you change a local administrator password? What utility would you use to look at Windows logs? Describe the difference between RAM and a hard drive to a non-technical user. A user calls and says that Excel keeps freezing up. Explain how you would troubleshoot.
