1. Right Answer: C
Explanation: Never overlook the obvious! Perform problem determination by checking all connections first, and that includes power connections. If you find that the PC is plugged in, then your next step would be to verify the power supply as that also could cause a dead computer.
2. Right Answer: A
Explanation: To set up dual monitors in Windows 7 you select the Extend My Desktop check box. This allows both monitors to be treated as a single large workspace. When extended the entire display area can be utilized and you can drag active windows between them seamlessly. The other options given are not available.
3. Right Answer: B
Explanation: The mini-PCIe slot is an internal laptop connection. It is usually accessed through a small access panel. USB and PCMCIA 802.11b/g adapters are available, but these are external devices.
4. Right Answer: A
Explanation: A DHCP server assigns IP addresses to client computers every time they request it. The computer that participates in a network asks for its IP address at startup. This is very often used in enterprise networks to reduce the configuration effort.
5. Right Answer: C
Explanation: Since all of the users are in the same general area, it is best to leave as much of their network configuration information unchanged as possible. As you know the router and the client use DHCP to negotiate IP address leases based on signal strength and quality. So by design, the client will negotiate with the server a few feet away over its normal configuration. This could cause problems with any statically assigned devices that the new router is not configured for.
