Which service allows a user export application usage and performance statistics with Cisco Application Visibility and control?

SNORT is an intrusion detection/prevention system (IDS/IPS) and is not primarily used for exporting application usage or performance statistics.

802.1X is a standard for port-based network access control, focusing on authentication rather than the export of application performance data.

SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices at a general level, but it does not provide the granular application-level flow data that AVC requires.

NetFlow is the core technology used by Cisco Application Visibility and Control (AVC) to collect and export detailed information about network traffic flows, enabling visibility into application usage and performance statistics.
