A small office uses a single Wi‑Fi router. Why is it a bad idea to keep the default network name (SSID)?

• A. The default SSID is usually the router's make and model.
• B. The default SSID is encrypted with a unique key.
• C. The default SSID automatically changes after a week.
• D. The default SSID improves compatibility with devices.

Answer: (A)

Revealing the router’s identity through the SSID makes your network an easier target. When the network name includes the brand and model, anyone nearby instantly knows exactly what hardware you’re using. That lets an attacker look up that specific device’s known vulnerabilities, default admin credentials, and configuration quirks, making targeted exploits more feasible. So changing to a generic or non-identifying name helps reduce this targeted information exposure.

The other statements don’t fit because the SSID isn’t encrypted as part of the name itself, and it doesn’t automatically change or improve device compatibility. Encryption protects data, not the network name, and compatibility isn’t affected by what you name the network.
