VMware 6V0-22.25 Practice Exam Questions & Answers

Avi Load Balancer Network Security Policies operate at the network security layer and are used to control whether traffic is accepted, discarded, denied, or rate-limited before higher-level HTTP processing occurs. Broadcom's Avi documentation specifically describes Network Security Policy behavior as determining whether a connection should be accepted, discarded, or rate-limited. Because of this, Rate Limit is a valid Network Security Policy action. ''Send Local Response'' and ''Redirect'' are HTTP-layer actions that belong to HTTP policies, not Network Security Policies. ''Continue'' is commonly associated with policy flow processing in other policy types but is not the correct Network Security Policy action in this question. Therefore, the valid action from the listed options is Rate Limit.

The HTTP Application Profile contains HTTP-specific behavior for a Virtual Service. VMware Avi documentation describes the HTTP profile as providing HTTP proxy functionality, including features such as redirects. Other HTTP profile capabilities include compression behavior and HTTP header handling such as X-Forwarded-For insertion. Web Application Firewall, however, is not configured inside the HTTP profile. WAF is configured using WAF profiles and WAF policies, and a WAF policy is then associated with the Virtual Service. This separation is important because an HTTP profile controls HTTP proxy behavior, while WAF controls application-layer security inspection. Therefore, among the listed options, the functionality that is not configured in the HTTP profile is Web Application Firewall.

An HTTPS client shows an untrusted certificate warning when the presented certificate cannot be validated by the client. Common causes include an expired certificate, a self-signed certificate, or a certificate signed by an internal certificate authority that the client does not trust. Avi documentation distinguishes between RSA and EC certificates as certificate algorithm types that can both be used by Virtual Services. A certificate being RSA instead of EC does not inherently make it untrusted. RSA certificates are still valid and supported when issued by a trusted CA, within their validity period, and matching the requested hostname. Therefore, the certificate algorithm alone is not a cause of an untrusted certificate error. The answer that would not cause the issue is B.

The Virtual Service Analytics page provides different graph categories for traffic, connection, timing, and error visibility. VMware Avi documentation states that the Requests chart shows the number of responses to requests per second and breaks down successful requests versus errors, including 4xx and 5xx errors. This makes the Requests graph the appropriate place to view the rate of HTTP 5xx errors for a Virtual Service. The Conns graph is focused on connection counts and rates, while End-to-End Timing shows timing components such as client RTT, server RTT, application response, and data transfer. ''HTTP Errors'' may sound plausible, but in the Avi Virtual Service Analytics graph naming described here, 5xx rate visibility is included under Requests.

Avi Load Balancer has built-in certificate-expiration visibility. VMware Avi documentation states that when a certificate approaches expiration, the related Virtual Service can receive a security penalty; for example, at 30 days before expiration the Virtual Service incurs a 20-point security penalty, which caps the health score at 80. The UI also changes certificate status indicators as expiration approaches, and system events are generated at expiration thresholds such as 30 days, 7 days, and 1 day. Email notifications, however, depend on administrator notification settings and email configuration. Because email delivery requires additional configuration and is not simply enabled by default for administrators, the non-default method listed is sending emails before expiration.

The Pool > Server view is focused on backend server health and monitor-related visibility. From this location, Avi provides details about the selected pool member, including active and passive health monitor information, server health state, and health-check performance indicators such as monitor success and response timing. These details help administrators understand why a pool member is up, down, or degraded. Client response success percentage, however, is a Virtual Service or application traffic analytics metric, not a server health-monitor drill-down item. Client response success is based on application transactions between clients, the Service Engine, and backend servers, and is normally reviewed through Virtual Service analytics or logs rather than the Pool > Server health-monitor details. Therefore, the item not available from that server drill-down is Client response success percentage.

The Avi Controller performs centralized control-plane and management tasks, while Service Engines perform data-plane traffic processing. SSL/TLS termination, HTTP header manipulation, and other live traffic-processing functions occur on Service Engines, not the Controller. Client DNS resolution for GSLB is handled by Avi DNS/GSLB services through Virtual Services and Service Engines. Certificate lifecycle management, however, is a Controller-side administrative function. Avi documentation describes automatic certificate renewal, where the Controller scans configured certificates for expiry, generates events before expiration, and attempts renewal when a certificate management profile is configured. This is a management-plane workflow rather than a packet-processing task. Therefore, among the listed options, the task performed by the Avi Controller is Renew SSL/TLS Certificates.
