   • The WAP transmitter light is dim
   • The terminal emulation software is misconfigured
   • The LWAPP image is installed on the WAP

6. DRAG DROP

   Your company recently purchased a new building down the street from the existing office.

   INSTRUCTIONS

   For each of the tasks below, select the appropriate antenna type and encryption object for all wireless access point (AP).

   1. Create an encrypted wireless connection between the two buildings that BEST controls signal propagation, while maximizing security.
   2. Restrict the wireless signal generated by the access points (APs) inside Building 1, so that it minimizes broadcast beyond the building.
   3. Maximize wireless coverage inside Building 1.
   4. Building 1’s internal wireless network is for visitors only and must not require any special configuration on the visitor’s device to connect.

   If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

   When you have completed the simulation, select the Done button to submit.

   If you previously made any changes to the simulated environment for the question, those changes were saved and will be present when you continue.

   

7. A technician has installed a Linux server in the tax office. The server can access most of the resources on the network, but it cannot connect to another server that has a share for backup.
