What are the primary responsibilities of the Service Engine in Avi Vantage? (Choose Two)

Question

Options

• AExecuting load balancing decisions
• BManaging user sessions
• CStoring persistent configuration data
• DGenerating SSL certificates

• A
  94% (15)
• D
  6% (1)

Explanation

In Avi Vantage, the Service Engine (SE) operates as the data plane component - it is responsible for executing load balancing decisions (A) by actively forwarding and distributing client traffic to backend servers in real time. It also handles managing user sessions (B), including TCP connection management, session persistence (sticky sessions), and SSL session state, which are all performed at the traffic-processing layer.

Why the distractors are wrong:

• C (Storing persistent configuration) - Configuration storage is the responsibility of the Avi Controller, which acts as the centralized management/control plane.
• D (Generating SSL certificates) - Certificate issuance and management is also a Controller function (integrated with CAs or ACME); the SE uses certificates but does not generate them.

Memory tip: Think of the SE as the "hands" and the Controller as the "brain." The SE does the work on live traffic (load balancing, sessions), while the Controller thinks and stores (config, certs, analytics aggregation). If a task touches live traffic → SE; if it touches configuration or management → Controller.
