6V0-22.25 VMware Avi Load 30.x Administrator Free Practice Exam Questions (2026 Updated)

The default Avi Load Balancer behavior for impending SSL/TLS certificate expiration includes visible operational indicators in the UI and health score impact. VMware Avi documentation explains that certificates approaching expiration affect the Virtual Service by applying a security penalty. At 30 days before expiration, the Virtual Service incurs a 20-point security penalty and the maximum health score is capped at 80. The certificates page also provides visual indication of certificate status using color changes as certificates approach expiration. Email and SNMP alerting require notification or external integration configuration, so they are not the default mechanisms. A top red UI banner is not the standard default certificate-expiry alerting mechanism described for this case. Therefore, the correct default mechanisms are health score security penalty and SSL certificate color status indicators.

VMware Avi Load Balancer documentation recommends EC with PFS because RSA 2K keys are more computationally expensive than EC, and EC with PFS provides the best performance and the best possible security. Therefore, the strongest and preferred cipher type among the listed options is EC with PFS .

Avi Load Balancer supports sharing a single VIP across multiple Virtual Services when each Virtual Service uses a different service port. This is useful when multiple applications or protocols must use the same IP address but separate listener ports, profiles, pools, and policies. Broadcom documentation for sharing a single VIP across multiple Virtual Services describes selecting an existing VS VIP while creating another Virtual Service. This avoids manually typing the same IP address as a separate allocation, which could create duplicate or inconsistent VIP configuration. Creating a child Virtual Service is used for other use cases, such as SNI or parent-child designs, not simply reusing the same VIP on a different port. Therefore, the correct method is to use Advanced Setup and select the existing VS VIP.

Avi HTTP compression behavior is influenced by network latency and compression policy settings. Broadcom’s Avi documentation explains that when round-trip time is less than 10 ms, no compression is applied; when RTT is between 10 ms and 200 ms, normal compression is used; and when RTT is above 200 ms, aggressive compression may be used. This is especially relevant in a lab environment, where client-to-Service-Engine latency is often extremely low. In that situation, compression can be correctly enabled, but Avi may choose not to compress responses because the RTT is below the threshold where compression is considered beneficial. Therefore, the most likely reason initial tests do not show compression is that the default behavior excludes traffic with RTT below 10 ms.

Avi WAF supports several inspection methods, including signature-based protection, allow-list style controls, and Positive Security. Positive Security is more computationally expensive because it validates application behavior against learned or configured rules that define what is explicitly allowed. This requires deeper inspection and more rule evaluation than simply matching known attack signatures. Signature inspection generally compares requests against known malicious patterns, while Positive Security evaluates whether requests conform to permitted application behavior. VMware Avi WAF documentation describes Positive Security and learning as a deeper application security method. Because it performs more detailed validation of acceptable behavior, it consumes more processing resources than the other listed methods. Therefore, the most computationally expensive inspection method is Positive Security.

A Service Engine Group defines how Service Engines are created, placed, scaled, and managed for Virtual Services. Properties such as high availability mode, Service Engine sizing, placement rules, scale-out behavior, and rebalance behavior are configured at the Service Engine Group level. Avi documentation includes the Auto Rebalance option as part of Service Engine Group behavior, allowing Avi to redistribute Virtual Services across Service Engines when appropriate. SSL Profiles and Analytics Profiles are normally applied to Virtual Services or associated profiles, not configured as core Service Engine Group properties. The Service Engine management network is normally part of the cloud or infrastructure networking setup rather than the SE Group property asked here. Therefore, the Service Engine Group property listed is Auto Rebalance Policy .

The Basic Setup wizard is intended for common Virtual Service creation, such as selecting the application type, defining basic service information, and adding servers. Advanced Setup exposes the complete set of Virtual Service configuration options through multiple tabs. Broadcom’s Avi documentation states that creating a Virtual Service in Advanced Setup allows administrators to configure all options through the available tabs. A custom Analytics Profile is an advanced Virtual Service setting because it changes how analytics, metrics, logs, health score behavior, and operational visibility are applied to that Virtual Service. Adding servers, specifying a VIP, and selecting HTTPS are normal Virtual Service creation activities and do not inherently require Advanced Setup. Therefore, the scenario requiring Advanced Setup is applying a custom Analytics Profile during Virtual Service creation.

VMware Avi Load Balancer supports HTTP-to-HTTPS redirection in more than one way. The HTTP application profile can perform a general HTTP-to-HTTPS redirect, but an HTTP Policy provides more granular control because policies can match on specific conditions and then apply actions. Avi documentation states that Virtual Service policies are more specific than general-purpose profiles and that policy rules take precedence over profile behavior. This makes HTTP Policy redirection more flexible than using only the HTTP profile, because administrators can build conditional redirect logic based on host, path, headers, or other HTTP match criteria. It is not incompatible with WAF, and it is not described as less efficient than DataScript for this purpose.

In Avi Load Balancer architecture, the Controller provides management, control-plane functions, configuration, analytics coordination, and automation, while the Service Engines provide the distributed data plane. Virtual Services advertise a Virtual IP address and one or more ports, but the traffic is actually processed by Service Engines. Broadcom documentation describes the Avi Service Engine as being programmed by the Avi Controller to advertise Virtual IP addresses. This means the VIP is not hosted directly by the API server, the Controller cluster, or a single Controller node. Those components manage and configure the system, but client traffic to the VIP is received and processed by the Service Engine data plane. Therefore, the architectural component that hosts Virtual IP addresses is the Service Engine.

Avi Load Balancer data-plane performance is provided by Service Engines, so scaling performance means increasing Service Engine processing capacity or distributing traffic across more Service Engines. Broadcom documentation for Autoscale Service Engines states that Avi supports three techniques to scale data-plane performance: vertical scaling of individual Service Engine performance, native horizontal scaling of Service Engines in a group, and ECMP horizontal scale-out. Increasing individual SE resources is vertical scaling. Native horizontal scale-out places a Virtual Service across multiple SEs using Avi’s native scale-out model. ECMP horizontal scale-out distributes traffic using equal-cost multipath routing. Increasing the maximum number of Service Engines only raises a limit; it does not itself scale active data-plane performance. Virtual Service priority affects placement decisions, not a direct scaling method.

VMware Avi Load Balancer supports scaling a Virtual Service across multiple Service Engines. The documentation for automatic scaling of Virtual Services references using the Scale Out action for a Virtual Service to increase the number of Service Engines actively supporting that Virtual Service. Therefore, the correct action is to use the Scale Out button in the Virtual Service popup.

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 client logging through Virtual Service analytics and client log filters. Client log filters are specifically designed to capture selected traffic, such as traffic from a chosen client IP address or matching log conditions. DataScripts can also write custom log data; VMware Avi DataScript documentation describes log-related functions and examples for creating local logs with custom data. HTTP policies can affect request and response processing and can be used with logging and analytics workflows. However, Custom Alert Config is for alert generation based on events or conditions; it is not a mechanism for creating custom client log entries. Therefore, the option that cannot be used to create custom client logs is Custom Alert Config .

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.

Avi Load Balancer supports presenting both RSA and EC certificates on the same SSL/TLS Virtual Service. When both are available, certificate selection can influence SSL performance. EC certificates generally provide strong security with lower computational overhead than RSA, especially compared with larger RSA keys. VMware Avi documentation includes guidance for EC versus RSA Certificate Priority , which exists specifically because certificate ordering and preference matter when both certificate types are configured. Disabling SSL session reuse would usually hurt performance, not improve it. Scaling out to another Service Engine can improve capacity, but it does not specifically optimize SSL cryptographic efficiency. Disabling PFS would reduce security, so it violates the question’s requirement. Therefore, preferring EC before RSA is the correct performance improvement without compromising security.

Avi WAF Policies can operate in different modes. Detection mode observes and logs WAF rule matches without blocking user traffic, which makes it useful for tuning a WAF policy before enforcement. Enforcement mode actively blocks requests that match blocking WAF rules or violate the configured policy. Broadcom documentation for WAF mode describes Detection and Enforcement as the two supported WAF policy modes, and Avi HTTP error documentation states that WAF can return a 403 Request Forbidden response when running in enforcement mode. Disabled signatures would reduce WAF blocking, not cause it. Learning mode helps generate recommendations and does not itself explain active blocking. Therefore, the likely cause of users receiving 403 Forbidden after attaching a new WAF Policy is that the policy is in enforcement mode.

Avi DataScripts are used to customize traffic handling beyond standard profile and policy capabilities. VMware Avi DataScript documentation states that DataScripts are lightweight scripts coded in Lua . The DataScript language is built on an embedded Lua interpreter with Avi-specific libraries and functions added for load-balancing use cases. This allows administrators to inspect HTTP requests and responses, manipulate headers, perform content switching, redirect traffic, select pools, and log custom information. TCL is commonly associated with some legacy load balancer scripting environments, but it is not Avi DataScript’s language. Python may be used for external automation through APIs, and Node.js is unrelated to Avi DataScript syntax. Therefore, the correct scripting language for Avi DataScripts is Lua .

The Avi architecture separates control-plane and data-plane responsibilities. Service Engines perform data-plane tasks, including traffic processing, inserting persistence cookies, health checking pool members, and handling load-balanced connections. The Avi Controller provides centralized management, analytics, configuration, and operational visibility. Broadcom’s Avi documentation explains that when an administrator requests to view Virtual Service or pool logs, the Controller pulls logs from Service Engines, indexes them, and displays the results. This makes log indexing a Controller function. By contrast, inserting cookies and checking backend server health occur in the Service Engine data plane. Active-active packet processing decisions are also handled by Service Engines according to the Virtual Service placement and traffic flow. Therefore, the task performed by the Avi Controller is indexing client logs .
