CompTIA A+ 220-1102 Practice Question

The correct answer is to set a strong password for the router's admin interface. Default passwords are widely known and could be used by malicious actors to gain control of the router. Changing the password to a strong, unique one significantly enhances security. Merely enabling WPA2 encryption or setting a firewall rule does not address the vulnerability posed by the default admin password. Disabling SSID broadcast can add privacy but does not protect against someone accessing the router's admin interface using the default password.
