The Riverbed AppResponse Database (DBA) module is an agentless, network-based monitoring solution. Its core function is to passively capture and analyze network packets related to database transactions from a SPAN port or network tap. This methodology allows it to monitor database performance without installing any software (agents) on the database servers themselves. Therefore, the statement that it "Requires the installation of an agent" is fundamentally incorrect and not a property of the module. Its agentless nature is a key design principle and a significant operational benefit.

A. Provides passive transaction level monitoring

This is a core feature. The module passively inspects network traffic to reconstruct and analyze individual database transactions without impacting the server.

B. Does not require access to the database server

This is a direct result of its agentless, network-based architecture. Monitoring is performed from the network, eliminating the need for server credentials or software installation.

D. Supports Major DBMS

To be an effective enterprise solution, the module is designed to parse and analyze the protocols of numerous major database systems, including Oracle, SQL Server, DB2, and others.

1. Riverbed AppResponse 11 Data Sheet: "AppResponse is a passive, network-based monitoring solution that performs real-time and historical analysis of network traffic... The Database Analysis Module provides detailed performance metrics for Oracle, SQL Server, DB2, Sybase, Informix, Teradata, MySQL, and PostgreSQL database transactions." (This confirms options A, B, and D are true properties, making C the only false statement).

2. Riverbed AppResponse 11.13.1 User's Guide, Chapter 1: "Introduction to AppResponse 11," Section: "How AppResponse 11 Works": The guide describes AppResponse 11 as a system that "passively monitors the network" by analyzing packet data from a capture source. This documentation consistently frames the solution as agentless and network-based, which directly contradicts the claim that an agent is required.
