Exam 200-201 topic 1 question 72 discussion

Correct D and E AVC can do many things. Attention to the question. The engineering needs: visibility on several parameters - metrics collection and exporting (D) identify unknown software by its network traffic flow - application recognition (E)

E. Application recognition: This feature allows the engineer to identify the type of application running on the network by analyzing its traffic flow. It can help identify unknown software and monitor the usage of known applications. D. Metrics collection and exporting: This feature allows the engineer to collect and export network performance metrics such as TCP bandwidth usage, response time, and latency. These metrics can provide insights into the overall network performance and can help the engineer to identify and troubleshoot performance issues.

DPI feature = Application Recognition TCP performance = Metrics Collection and Exporting

Cisco Application Visibility and Control (AVC) uses deep packet inspection found in Layers 3 and 7 to recognize, analyse, and control over 1000 Applications that include voice and video, email, file sharing, gaming, peer-to-peer (P2P), and cloud-based Applications. AVC combines several Cisco IOS/IOS XE components, as well as communicating with external tools, to integrate the functions of Application Recognition; Metrics Collection and Exporting; Management and Reporting Systems; and Control, i.e. prioritization and management of application bandwidth, functionality into their firewall.

why not A ?
