A client requests a small SOHO wireless network setup. The client has only three devices that will require access to the Internet. The client is also concerned that a neighboring business will…

Explanation

Lowering radio power levels (B) reduces the wireless signal range so it does not extend into the neighboring business's space, limiting who can even detect and attempt to connect to the network. Enabling MAC filtering (E) creates an allowlist of the three known device MAC addresses, so only those specific devices are permitted to connect - an unknown device from the neighbor would be rejected even if it could detect the signal. Client isolation (A) prevents connected devices from seeing each other but doesn't stop unauthorized users from joining. Disabling unused ports (D) is a wired switch security measure, not relevant here. Enable short preambles (F) is a performance setting with no security benefit. Together, B and E address both signal exposure and access control.
