Which mode uses a wireless access point (WAP) connected to a wired network?

Infrastructure mode is the correct choice because it involves a wireless access point (WAP) connected to a wired network, allowing wireless devices to communicate with each other and with the wired network through the access point. This mode is commonly used in home and enterprise environments, where the WAP serves as a central hub that facilitates connectivity for multiple clients.

In this configuration, the access point acts as a bridge between wireless clients and the wired network, enabling devices to access resources, share data, and connect to the internet. This centralized model enhances network management and security since all wireless communications are routed through the access point.

Other modes, such as ad-hoc mode, enable direct communication between wireless devices without the need for an access point, effectively creating a peer-to-peer network. Direct connection mode generally refers to the establishment of a direct pathway between two devices without involving a network infrastructure, while peer-to-peer highlights the connectivity among devices directly rather than through a central access point. Hence, these alternatives do not involve the use of a wireless access point with a wired network, distinguishing infrastructure mode as the accurate answer.
