In Avi Elastic HA N+M mode, the N value represents the minimum active scale required for a Virtual Service, while M represents additional capacity maintained for resiliency. Broadcom's Avi documentation explains that in N+M Elastic HA, M is the number of additional or buffer Service Engines that the Avi Load Balancer Controller maintains in the Service Engine Group. These buffer Service Engines provide spare capacity for failover, scale-out, and placement flexibility. This is separate from the maximum number of Service Engines in the group, which defines the upper limit of SEs that can exist. It is also separate from the maximum number of Virtual Services per Service Engine. Therefore, the ''M'' in N+M Elastic HA refers to the number of buffer Service Engines.

The Basic Virtual Service creation workflow is intended for common settings and does not expose every placement and advanced option. VMware Avi documentation states that creating a Virtual Service in Advanced Setup allows configuration of all options through the available tabs. Service Engine Group selection is a Virtual Service placement property, so when a Virtual Service must be placed on Service Engines belonging to a specific Service Engine Group, the administrator should use Advanced Setup and set the Service Engine Group in the Advanced section. The Policy section is for traffic policy logic, not Service Engine placement. Therefore, the correct method is to create the Virtual Service in Advanced mode and override the default Service Engine Group in the Advanced section.

Avi Load Balancer supports sharing a single VIP across multiple Virtual Services when the Virtual Services use different listener ports. This is the correct design when different application protocols must be served on the same IP address but require different profiles, pools, and processing behavior. An existing Layer 7 HTTPS Virtual Service with SSL termination and WAF should not be converted into a mixed L7/L4 object for SMTP. SMTP should use its own Virtual Service with an appropriate Layer 4 profile and backend SMTP pool. Broadcom documentation specifically states that a single VIP can be shared across multiple Virtual Services by choosing different ports for each Virtual Service. Therefore, the correct approach is to create a second Virtual Service reusing the same VIP, with separate SMTP listener ports, L4 profile, and SMTP pool.

Connection Multiplexing is most valuable when client behavior would otherwise create many short-lived server-side TCP connections. HTTP/1.0 is the best fit for this benefit because HTTP/1.0 commonly opens a separate TCP connection for each request unless keepalive behavior is specifically used. Avi Connection Multiplexing decouples the client-side connection from the server-side connection and allows the Service Engine to reuse server-side TCP connections for multiple HTTP requests. This reduces connection setup and teardown load on backend servers. HTTP/1.1 already introduced persistent connections as a standard behavior, so the relative benefit is smaller than with HTTP/1.0. HTTP/2 has its own multiplexing model at the protocol level. Therefore, Connection Multiplexing is most valuable for HTTP v1.0.

In Avi Load Balancer architecture, the data plane is provided by Service Engines. Service Engines process application traffic, host Virtual Services, terminate client and server connections where appropriate, perform load balancing decisions, and execute pool health monitoring. The Controller is the centralized management, control, and analytics platform; it handles configuration, orchestration, lifecycle management, and log indexing. Configuration backups are also Controller administrative functions rather than Service Engine data-plane functions. Health monitoring must occur close to the traffic path because Service Engines need to know whether backend pool members are available before sending client requests to them. Therefore, among the listed options, Pool health monitoring is the function performed by the data plane.
