Which component in the Avi architecture hosts Virtual Services?

Question

Options

• AController cluster
• BService Engine
• CAPI server
• DSingle controller node

• A
  5% (1)
• B
  89% (17)
• D

Explanation

Service Engines (SEs) are the data plane components in Avi Networks architecture, and they are responsible for hosting and running Virtual Services - processing actual client traffic, applying load balancing policies, and performing SSL offload.

• A (Controller cluster) is wrong because the controller cluster is the management/control plane - it handles configuration, analytics, and orchestration, but does not process production traffic itself.
• C (API server) is wrong because the API server is simply the interface through which administrators interact with the controller; it has no role in hosting or executing Virtual Services.
• D (Single controller node) is wrong for the same reason as A - individual controller nodes are management components, not data plane elements. A single node also implies no HA, which is architecturally distinct from the controller cluster.

Memory tip: Think of the split as "Control vs. Carry." The Controller controls the system; the Service Engine carries the traffic. Virtual Services live where the traffic flows - on the SE.
