A small office owner has asked a technician to ensure all users in the office have the ability to access the wireless network but that the network is not accessible outside the building. Which of…

Options

• AChange the static IP addresses
• BChange the antenna placement
• CChange the default SSID
• DChange the radio power level
• EChange the encryption type
• FChange the content filtering settings

• F

Explanation

Changing antenna placement (B) and changing the radio power level (D) are the two physical methods that directly control the geographic reach of a wireless signal. Repositioning antennas (e.g., using directional antennas pointed inward or placing omnidirectional antennas centrally) prevents signal from leaking outside the building. Reducing the radio transmit power limits signal range so it does not extend beyond the walls. The other options do not address signal containment: changing static IPs (A) is a network addressing change, changing the default SSID (C) only renames the network but does not hide or contain it, changing encryption type (E) secures data in transit but does not limit physical signal reach, and changing content filtering (F) controls what websites are accessible, not who can reach the network.
