Devices that connect to a router/switch/hub and provide WiFi signals in a large building or office.

• A. Access Points
• B. Access Token
• C. Account Lockout
• D. Active Desktop

Answer: (A)

The main idea here is wireless network infrastructure. Access points are the devices that connect to a router or switch and emit WiFi signals to serve wireless devices. In a large building or office, you deploy multiple of these to blanket the area with coverage, ensuring users can roam between areas without losing connectivity. Each access point sits on the wired network (often via PoE) and broadcasts the wireless network’s SSID, letting laptops, phones, and other devices connect to the internet and to resources on the wired network. In larger deployments, you manage many access points together through a controller or cloud-based management so settings, channels, and security stay consistent and performance is optimized.

The other terms aren’t about devices that provide wireless coverage: an access token is used for authenticating access to services, an account lockout is a security policy about failed login attempts, and an active desktop is a legacy user interface feature.
