Which of the following utilities would a technician use to determine network utilization?

The Start Menu is a navigation interface for launching programs and accessing system features and provides no network utilization data.

My Network Places displays network shares and connections but does not show real-time bandwidth or utilization metrics.

Administrative Tools provides access to management consoles such as Event Viewer and Computer Management but does not display real-time network utilization.

Task Manager's Performance tab (and dedicated Networking tab in Windows 7) displays current network utilization as a percentage of total link bandwidth in real time. This allows a technician to quickly identify whether a network adapter is saturated or if abnormal traffic is present.
