What action is recommended to reduce unauthorized access from outside by radio placement?

• A. Move APs away from exterior walls
• B. Relocate APs closer to exterior walls
• C. Increase the AP transmit power
• D. Disable SSID broadcast

Answer: (B)

The action being tested is about keeping wireless signals inside the building and away from outside listeners. To reduce unauthorized access from outside, you want the APs arranged so that the exterior environment dampens the signal as much as possible before it leaves the building. Putting APs away from exterior walls means the radio waves must pass through more interior walls and barriers, which reduces the strength of any leakage outside.

Relocating APs closer to exterior walls would let more signal escape, increasing the chance that someone outside could pick up the network. Turning up transmit power would boost leakage as well, making outside access easier, not harder. Disabling SSID broadcast hides the network from casual discovery but doesn’t prevent someone from connecting if they know or can guess the network, and it often offers minimal security benefit compared to proper placement and other controls.

So, moving APs away from exterior walls best minimizes outside leakage and unauthorized access.
