Baselining Web Traffic

AE.

To baseline web traffic on a per-session basis for network application reporting, the two mechanisms that can be combined are Flexible NetFlow and Network-Based Application Recognition.

1. Flexible NetFlow: Flexible NetFlow is a feature of Cisco IOS that allows the collection and analysis of network traffic data. It provides a flexible way to customize the fields that are exported in NetFlow records. Flexible NetFlow can be used to collect information about various aspects of network traffic, including application-level information.

With Flexible NetFlow, you can collect per-session data, which can help you understand application usage patterns, identify potential security threats, and troubleshoot network performance issues. By monitoring network traffic on a per-session basis, you can gain a better understanding of how applications are being used and identify trends that may be impacting network performance.

2. Network-Based Application Recognition: Network-Based Application Recognition (NBAR) is a Cisco IOS feature that provides advanced application-level visibility and control. NBAR allows you to classify network traffic based on the application protocol, and it supports hundreds of protocols, including web-based protocols such as HTTP and HTTPS.

By combining Flexible NetFlow with NBAR, you can create a powerful tool for monitoring and managing network traffic. Flexible NetFlow can be used to collect per-session data, while NBAR can be used to classify traffic based on the application protocol. This combination allows you to gain insight into how specific applications are being used and how they are impacting network performance.

Therefore, the correct answers are A. Flexible Netflow and E. Network-Based Application Recognition.
