- Grant the users read permissions on all files.
- Give the users administrator rights on their computers.
- Make the users members of a group called Backup Operators.
- Check the Folder is Ready for Archiving box in the properties of each folder.

- Aim directly at the center of the flame, squeeze the lever, and sweep from side to side.
- Aim at the base of the flame, squeeze the lever, and sweep from the base to the top of the flame.
- Aim just above the flame, squeeze the lever, and sweep from the top to the base of the flame.
Anyone using a fire extinguisher should remember the basic rules of operation:
P – Pull the pin.
A – Aim at the base of the fire, not at the flames.
S – Squeeze the lever.
S – Sweep the nozzle from side to side.
What type of device provides power to a computer and allows it to be safely shut down in the event of a power loss?
- surge suppressor
- uninterruptible power supply

Which measure can help control RFI effects on wireless networks?
- Ensure the humidity and temperature levels are set as low as possible.
- Ensure the number of wireless NICs exceeds the number of wireless phones.
- Ensure the wireless network is on a different frequency than the offending source.
- Ensure each wireless NIC is configured to operate at different frequencies from all other wireless NICs.
Explanation:A wireless network (IEEE 802.11) can be affected by radio frequency interference because it shares the same radio frequency range with other devices, such as cordless phones.
A computer is assigned an IP address of 169.254.33.16. What can be said about the computer, based on the assigned address?
- It cannot communicate outside its own network.
- It can communicate on the local network as well as on the Internet.
- It can communicate with networks inside a particular company with subnets.
- It has a public IP address that has been translated to a private IP address.
Explanation:If a computer is configured with DHCP but it cannot communicate with the DHCP server in order to obtain an IP address, the Windows OS automatically assigns a link-local IP, in the range of 169.254.0.0 to 169.254.255.255. The computer can only communicate with other computers connected to the same 169.254.0.0/16 network and cannot communicate with computers in another network.

A network administrator has finished migrating from a peer-to-peer network to a new client-server network configuration. What are two advantages of the new configuration? (Choose two.)
- The total cost of the new solution is considerably lower.
- Data is more secure in the event of hardware failures.
- Individual users are in control of their own computers and network resources.
- Data resources and access are centrally controlled.
- Personnel costs are lower because a dedicated network administrator is no longer necessary.
Explanation:Centralization in a client-server network configuration provides better monitoring for security, as well as easier access to resources. The total cost may be higher because a network administrator is required, but reliability and scalability are enhanced.
