Avi Virtual Service policies are evaluated according to policy type and rule order. Broadcom documentation explains that Virtual Service policies customize network-layer and HTTP-layer behavior, and policy logs are visible through the Virtual Service Logs tab. Because policies contain match conditions and actions, their order matters: earlier matching rules or policy sets can affect whether later rules are reached or what traffic state later processing receives. Policies and DataScripts can both be used on the same Virtual Service when designed correctly; they are not mutually exclusive. Policies can use advanced match criteria, including pattern-based matching in applicable HTTP contexts, so the statement that policies do not support regex is incorrect. HTTP Response Policies also do not require a matching HTTP Request Policy. Therefore, the true statement is that policy order matters.

Avi Web Application Firewall is enabled at the Virtual Service level. VMware Avi WAF documentation states that each Virtual Service can have one WAF Policy attached to it, and that attaching a WAF Policy to a Virtual Service immediately puts the policy into effect. This means WAF inspection is applied to the HTTP or HTTPS traffic handled by that Virtual Service. A Pool contains backend servers and health monitor configuration, so it is not where WAF is enabled. A Service Engine hosts and processes traffic for Virtual Services but does not receive WAF policy attachment directly for a specific application. An Application Profile controls HTTP behavior but is separate from WAF policy attachment. Therefore, the correct location to enable a WAF Policy is the Virtual Service.

Avi Network Security Policies are evaluated at the network-security layer and can be used for actions such as allowing, dropping, denying, rate limiting, and applying rules based on client characteristics such as IP reputation or geolocation. Blocking selected countries is supported through geolocation-based matching, and IP reputation is also a supported security capability in Avi. Rate limiting is a valid Network Security Policy action. Botnet Detection, however, is not configured through a Network Security Policy. Bot detection and bot management are part of Avi's WAF and bot-management security features, associated with application-layer HTTP security rather than the network security policy object. Therefore, the function that cannot be configured through a Network Security Policy is Botnet Detection.

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.

Applications that cannot be SNATed require preservation of the original client IP address. In Avi Load Balancer, preserving client IP is mutually exclusive with SNAT, because the Service Engine must forward traffic without replacing the source address. VMware Avi documentation for Preserve Client IP describes specific requirements and caveats for non-SNAT traffic handling. For this model, the Service Engine Group must use Legacy Active-Standby behavior, where the Virtual Service is active on one Service Engine and failover behavior is predictable. Elastic Active-Active mode generally relies on distributed placement and typically uses SNAT for symmetric return traffic handling. Therefore, when an application cannot use SNAT and must preserve the client IP address, the correct HA mode is Legacy Active-Standby.
