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.

Avi Load Balancer does not continuously forward and index every client transaction log by default. Broadcom documentation states that both significant and non-significant logs are not automatically forwarded by Service Engines to the Controller cluster for indexing by default. A newly created or newly enabled Virtual Service may show more log activity initially, but after the initial period, ordinary successful transactions are not shown unless non-significant logging or a user-defined client log filter is enabled. Significant logs, such as errors or policy-related events, continue to appear because they are operationally important. Therefore, if the Logs tab suddenly shows dramatically fewer entries after the first 30 minutes, the likely reason is that non-significant logs are not enabled.

Avi evaluates traffic according to the processing stage in the packet and HTTP transaction flow. Network Security Policy is evaluated first because it operates at the connection or network-security layer before HTTP request processing. After traffic is allowed through the network-security stage, HTTP security processing is applied to the HTTP transaction. HTTP Request Policies are then evaluated on the request path, where administrators can perform actions such as redirecting, switching pools, modifying headers, or sending a local response. DataScript Response runs later on the response side, after the request has been processed and a response is being handled. This staged order is why the correct sequence is Network Security HTTP Security HTTP Request DataScript Response.

Avi health monitors determine whether a pool server should receive traffic. For web applications, an HTTP or HTTPS health monitor can send a request to a specific URI and validate the response body or status code. VMware Avi documentation describes health monitor failures such as payload mismatch, where a server is marked down when the expected response content is not returned. The most reliable design is to make the application expose a health-check URI that performs its own dependency validation, including a database query, and returns the expected response only when the application and database path are functional. This confirms the actual application dependency rather than merely checking TCP reachability or the database independently. Therefore, the correct approach is to use an HTTP health monitor against a dependency-aware URI.

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.
