What does a wireless security profile specify?

• A. It defines the routing protocol for wireless networks.
• B. It lists authorized MAC addresses for wireless clients.
• C. It configures IP address assignment for wireless clients.
• D. It specifies the authentication and encryption settings used by wireless interfaces.

Answer: (D)

The main idea is that a wireless security profile controls how devices prove who they are and how their data is protected over the air. It specifies the authentication method (such as a pre-shared key or an 802.1X method) and the encryption settings (for example, AES with WPA2 or WPA3). This combination determines what credentials are needed to connect and how the wireless traffic is encrypted to keep it confidential. It doesn’t set routing protocols, which manage packet paths between networks; it doesn’t specify a list of allowed MAC addresses (that’s a separate access-control step), and it doesn’t handle IP address assignment (which is done by DHCP).
