Which credential is typically required for wireless access in networks using MAC filtering, as per common practice?

• A. Biometric scan.
• B. Smart card.
• C. SSID and password.
• D. Certificate issued by a public CA.

Answer: (C)

MAC filtering controls which devices can attempt to connect by their hardware address, but it does not provide the actual authentication needed to use the network. In everyday wireless access, you typically prove you belong by providing the network’s credentials—the SSID (the network name) and the password used by the WPA/WPA2 security. MAC filtering can add a modest extra layer, but it’s easily bypassed, and without the SSID/password you can’t even associate or decrypt traffic. Biometric scans or smart cards are not the standard for general wireless access, and while certificate-based methods exist in some enterprise setups, the common practice for most networks is SSID and password.
