Which factor most directly determines the sizing of a self-hosted Instana backend?
Select an answer to reveal the explanation.
Short Explanation
Sizing follows the data. How much telemetry arrives and how long you keep it drives storage and processing far more than how many people look at it.
Full Explanation
The correct answer is the factor based on telemetry volume and retention. Ingest rate and retention period together determine how much data the backend must process and store. Both are driven by the size and instrumentation depth of the monitored estate. The administrator login count is incorrect because interactive users generate query load but are a minor factor next to continuous telemetry ingest. The dashboard and custom view count is incorrect because dashboards are views over data that is already stored; adding views does not materially increase storage requirements. The application version numbering scheme is incorrect because application versioning has no bearing on backend capacity. For the exam, size self-hosted deployments from ingest volume and retention, and treat user count as a secondary consideration.
