For wireless detection, which of the following statements is correct?

• A. Authorized vendor devices
• B. USB drives
• C. WLAN cards inserted into system components
• D. Laptops allowed on wireless network

Answer: (C)

Wireless detection centers on uncovering any radio-enabled hardware that could connect to the network. WLAN cards inserted into system components are exactly that kind of hardware, because they bring wireless capability inside devices themselves, even if there isn’t a separate wireless module visible. Detecting these helps prevent rogue or unmanaged wireless access and keeps endpoint configurations aligned with security controls. The remaining options don’t target detecting wireless capability: authorized vendor devices cover general approved hardware rather than wireless detection, USB drives relate to removable media risks, and laptops on the wireless network describe policy for allowed devices rather than detection of wireless presence.
