Which action best describes isolating guest traffic in a small wireless network?

• A. Reduces range.
• B. Increases data rate.
• C. Allows admin access from guest.
• D. Keeps guest traffic segregated from main network for security.

Answer: (D)

Guest traffic isolation means placing guest devices on a separate network segment so they can access the Internet but cannot reach devices on the main network. This separation protects internal resources by preventing guests from seeing or interacting with servers, printers, or file shares, and it limits the potential spread of malware or misconfigurations from guest devices. In practice, you implement this by using a dedicated guest SSID tied to its own VLAN or subnet, with firewall rules or client isolation that blocks access to the main network while still providing Internet access. The other options don’t describe this protective separation: reducing radio range changes coverage but not how traffic is segregated; increasing data rate affects performance, not isolation; and allowing admin access from guests would defeat the purpose of keeping the main network secure.
