Important VMware 6V0-22.25 Exam Questions

Answer: C

Explanation:

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.

Answer: B

Explanation:

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.

Answer: D

Explanation:

When troubleshooting a busy Virtual Service, capturing all client logs can create unnecessary logging overhead and produce excessive data. Avi Load Balancer supports client log filters so administrators can selectively capture logs for traffic matching specific conditions, such as a particular client IP address. VMware Avi documentation describes creating user-defined filters for Virtual Service client logs, which allows operators to focus logging on targeted test traffic rather than enabling broad logging for all users. Modifying Apdex criteria changes performance scoring expectations, not logging overhead. Client Insights mode and analytics settings may affect visibility, but they do not provide the same targeted reduction in log volume. Therefore, the best method to minimize performance impact while troubleshooting a busy Virtual Service is to enable a client log filter for only the test user's IP addresses.

Answer: D

Explanation:

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.

Answer: C

Explanation:

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.
