5) Using good grammar describe the purpose of a site survey and how it relates to a wireless network.
answer
A site survey is a test of an area to see how the wireless network will be installed and configured. It enables you to determine the best placement of the access point and antenna as well as the coverage area. Furthermore, a site survey determines black holes or spots where coverage is inadequate, weak, or inconsistent

6) Using good grammar, give two examples of how a technician might be proactive at work.
answer
(1) A technician uses a software program that "freezes" the computer. A user who uses a different user ID than the technician is allowed to change applications and the operating system, but after the computer reboots, the computer is back the way it was originally. A technician needs to install Windows updates, antivirus updates, and plug-in updates. The technician logs in, makes the changes, and freezes the computer state. A proactive technician would log in with a normal user ID to ensure the computer works properly. (2) A technician has a part-time assistant. A computer user requests that a certain part be installed on a particular day. The technician delegates this request to the assistant. The assistant is out sick the day of the installation. A proactive technician would either call to let the computer user know the installation will not occur, or better yet, the proactive technician will go to perform the installation. Note that a reactive technician would just let this go and when the user calls, then talk with the customer.
