Which of the following is an indication of a connection to a network?

• A. Presence of extra drives
• B. Presence of other computers in Network
• C. Access to devices not directly attached to computer
• D. Indicator showing network activity in notification area

Answer: (D)

The key idea is recognizing when a device is actively connected to a network. The clearest sign is the network activity indicator in the notification area (the system tray). This icon lights up or changes when you’re connected to a network and there is data being sent or received, so it directly shows that your computer is on a network and communicating. Other options describe things that can be present without an active connection: extra drives might be local or mapped but won’t prove you’re connected at the moment; seeing other computers on the network just means the network exists, not that your device is currently connected; accessing devices not directly attached implies sharing may be possible, but it doesn’t by itself prove an active connection. The network activity indicator is the most immediate and reliable signal of an active network connection.
