Which of the following are prerequisites for discovering relationships between hosts in Portal Application Models? (Choose all that apply.)

Riverbed Portal's Application Models feature discovers and maps the communication relationships between hosts by analyzing network traffic data. The primary data sources for this discovery process are flow data and packet data. Flow-based data from NetProfiler provides information on conversations between IP addresses (hosts), while packet-based data from AppResponse offers deep packet inspection for high-fidelity application identification and communication mapping. Official Riverbed documentation explicitly states that Portal uses data from both NetProfiler and AppResponse for application discovery and dependency mapping, making them direct prerequisites.

A. SNMP-based data from NetIM is used to discover network topology and device health. While it provides context for the underlying network path, it does not discover the actual application communication relationships between hosts.

B. Code-level data from AppInternals traces application transactions. It shows relationships between application tiers (e.g., web-to-database) but is not the primary source for discovering network-level host-to-host dependencies in Portal.

D. End-User Device Data from Aternity focuses on performance from the user's device perspective. It does not provide the network traffic data required to map communication paths between servers or clients and servers.

The section "About application discovery and dependency mapping" explicitly states: "Portal uses data from NetProfiler and AppResponse to discover applications and their dependencies. Portal analyzes the traffic data from these products to automatically discover clients, servers, and the connections between them." This directly supports that both flow data (NetProfiler) and packet data (AppResponse) are prerequisites.

The section "Viewing network path details" states: "When Portal is integrated with NetIM, you can view the network path between application components." This clarifies that NetIM's role is to provide the network path as a contextual overlay, not to perform the initial discovery of host communication relationships.
