Free Practice Questions for VMware 6V0-22.25 Exam

Avi supports several persistence methods, and some require persistence tables stored in Service Engine memory. Client IP persistence uses a persistence table that maps client addresses to selected backend servers, which consumes Service Engine memory. TLS persistence also relies on state associated with TLS session behavior. App Cookie Persistence depends on application cookies and persistence handling that Avi must interpret or track. HTTP Cookie Persistence , however, is different because Avi can insert or use a cookie value that identifies the selected server, allowing the client to carry the persistence information in subsequent requests. This avoids maintaining the same kind of server-side persistence table in Service Engine memory. Therefore, the persistence type that does not consume Service Engine memory is HTTP Cookie Persistence .

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 .

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 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.

In Avi Load Balancer, disabling SNAT for a Virtual Service is handled through Preserve Client IP configuration. VMware Avi documentation states that preserving the client IP address is mutually exclusive with SNATing the Virtual Service. The related configuration is not part of the Application Profile or TCP Profile, because those profiles control application-layer or TCP proxy behavior rather than the forwarding model for source address preservation. It is also not simply a Service Engine Group property. For the supported configuration flow, Preserve Client IP is configured using a Network Service , including floating IP and related network service settings associated with the Service Engine Group, VRF, and cloud. Therefore, the correct section for configuring Preserve Client IP Address to disable SNAT is Network Service .

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 .

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 .

The Avi WAF Policy includes an option to bypass WAF inspection for static file extensions. VMware Avi documentation notes that static content file extensions can be bypassed from WAF checks. Among the listed options, .ico is the static web file type that matches this behavior; .batch, .exe, and .yml are not appropriate default static web bypass file types.

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.
