Question 3

A Network Architect is designing a solution for a large e-commerce platform that has very predictable, high-traffic "flash sale" events every weekend. The primary goal is to minimize infrastructure costs during weekdays while ensuring maximum performance during the sales. The platform is deployed in a vCenter environment. Which combination of Avi features should the architect use to create the most efficient scaling strategy? (Select all that apply.)

A. Implementing a Virtual Service scaling policy based on a time-of-day schedule. B. Configuring a higher 'Max Number of Service Engines' on the Virtual Service. C. Creating a custom alert with a control script that is triggered by high traffic metrics. D. Manually migrating the Virtual Service to a larger Service Engine before each sale. E. Using a GSLB policy to divert traffic to a different data center during sales.

Question 4

A vSphere Administrator is deploying a new critical application that cannot tolerate any downtime, even during a Service Engine failure. The application's traffic load requires the capacity of approximately three Service Engines. To provide both high availability and performance, the administrator scales the Virtual Service out to four Service Engines. What HA model does this configuration represent for the Virtual Service?

A. Active/Standby B. N+M, where N=3 and M=1 C. Active/Active D. Cold Standby

Question 6

An administrator is tasked with temporarily disabling all WAF processing for a specific Virtual Service to perform a baseline performance test. They need to ensure that the WAF engine does not inspect any traffic for this VS, but they want to keep the WAF configuration in place to re- enable it easily after the test.
The current WAF configuration for the Virtual Service is shown below.
# Virtual Service > WAF Policy
WAF Policy: custom-waf-policy-prod
Mode: Enforcement
What is the most direct and appropriate method to achieve this?

A. In the WAF Policy 'custom-waf-policy-prod', uncheck all signature rules. B. Delete the 'custom-waf-policy-prod' WAF Policy. C. In the Virtual Service editor, set the WAF Policy to 'None'. D. SSH into the Service Engine and stop the WAF process.

Question 7

A DevOps Engineer needs to enable the most granular level of logging for a specific Virtual Service to troubleshoot a transient application issue. The goal is to capture all individual requests and responses, including headers, for a short period. Which setting should be enabled in the Analytics Profile for this Virtual Service?

A. Set the "Log Analytics Events" flag on the health monitor. B. Set "Non-Significant Log Throttling" to zero. C. Enable "Log all requests". D. Enable "Client Log Streaming".

Question 8

A Service Engine in the data plane detects that a backend server in a pool has failed its health check. What is the sequence of events that follows?

A. The Service Engine waits for the administrator to manually mark the server as DOWN in the UI. B. The Service Engine sends an email alert directly to the administrator. C. The Service Engine sends the health status data up to the Avi Controller, which then marks the server as DOWN and updates any other relevant SEs. D. The Service Engine immediately stops sending traffic to the failed server and notifies the other SEs directly.

Question 9

An application owner reports that their application is "down". An Operator checks the Avi dashboard and finds that the Health Score for the corresponding virtual service is 1. The Operator observes that all four components of the Health Score (Performance, Resource, Anomaly, Security) are extremely low. What are the possible root causes for such a catastrophic failure?
(Select all that apply.)

A. The virtual service's VIP address has been misconfigured on the upstream router. B. A network outage has occurred between the Avi Controller and the Service Engines. C. The single Service Engine hosting the virtual service has crashed or lost power. D. The "Log Successful Checks" option on the health monitor was disabled. E. All backend servers in the pool are powered off or have lost network connectivity. F. The administrator's password for the Avi Controller UI has expired.

Question 10

A vSphere Administrator is reviewing two different HA configurations in Avi. Configuration A is a Service Engine Group in N+M mode. Configuration B is a Virtual Service scaled out across multiple SEs. What is the fundamental difference between these two HA models?

A. N+M provides protection against SE failure, while Active/Active (scale out) provides protection against backend server failure. B. N+M is an Active/Standby model for SEs, while Active/Active (scale out) is an Active/Active model for the Virtual Service itself. C. N+M is used for L4 virtual services, while Active/Active is used for L7 virtual services. D. N+M requires manual intervention to fail over, while Active/Active is fully automated.

Question 11

An application requires client requests to be distributed based on a value in the HTTP URI. For instance, all requests for /api/v1/us-east/... should go to pool-us-east and all requests for
/api/v1/us- west/... should go to pool-us-west. Which load balancing algorithm, when combined with a specific string from the URI, can achieve this deterministic routing?

A. Fastest Response B. Consistent Hash C. Round Robin D. Least Connections

Question 12

A Security Administrator is investigating an alert and reviews a Virtual Service log entry that shows a WAF event. The administrator needs to know which specific security rule was triggered by the client's request. Which fields in the WAF log data would provide this information? (Choose
2.)

A. WAF_Mode B. Rule_ID C. Client_IP D. Rule_Group E. Response_Code
