Why each option
Cisco NBAR2 (Network-Based Application Recognition 2) is the technology that performs deep packet inspection to identify and classify applications across Layers 3 through 7 of network traffic.
Cisco NBAR2 provides advanced application visibility by performing deep packet inspection (DPI) on network traffic. It can identify and classify thousands of applications based on various attributes beyond just port numbers, including signatures, URLs, and host names, across Layers 3-7.
Cisco ASAV is a virtual firewall appliance providing network security services, not primarily an application identification engine.
Account on Resolution is not a recognized Cisco technology or network monitoring feature.
Cisco Prime Infrastructure is a network management system for configuration and monitoring, not a deep packet inspection engine.
