What are two functions of the Service Engines in NSX Advanced Load Balancer? (Choose two.)

The NSX Advanced Load Balancer (formerly Avi Networks) architecture separates the control plane (Controller) from the data plane (Service Engines). The Service Engines (SEs) are the lightweight data plane proxies that handle all traffic. Their primary function is to perform the actual load balancing of application traffic (Option C). As they process this traffic, they also gather detailed, real-time telemetry and analytics on application performance, security, and client experience, which are then sent to the Controller for aggregation and visualization (Option A).

B. The NSX ALB Controller, not the Service Engine, is the central repository that stores all configuration and policies.
D. Service Engines are the load balancers; they are lightweight virtual appliances that directly handle traffic, not deploy other servers.
E. The NSX ALB Controller provides the centralized user interface (UI), API, and CLI for all configuration and management tasks. ---

"NSX Advanced Load Balancer (Avi) Architecture":

Section: Avi Service Engines: "The Avi Service Engines (SEs) are the data plane engines. They are lightweight virtual machines that handle all data plane operations... The SEs perform load balancing and all client- and server-facing network interactions... The SEs collect real-time application telemetry for every transaction and send the information to the Controller." This directly supports answers A and C.

Section: Avi Controller: "The Avi Controller is the single point of management and control that serves as the brain of the Avi Vantage platform... It provides the portal for administrators to specify the desired state of the data plane." This directly refutes answers B and E.

"Overview of NSX Advanced Load Balancer":

Section: Components: "Service Engines (SEs) — The SEs are the distributed load balancers that are deployed close to the application servers... The SEs provide the data plane services." This supports answer C.

Section: Components: "Controller — The Controller is the centralized management component of the system. The Controller holds the management and control plane functions." This refutes answers B and E.
