Why is a single test host a poor basis for sizing a production Instana deployment?
Select an answer to reveal the explanation.
Short Explanation
One quiet host won't tell you what a busy production estate produces. You need to size from real host count, technology mix, and trace rate, not from one lightly loaded test host.
Full Explanation
The correct answer is the option saying telemetry volume depends on host count, technologies in use, and trace rate, none of which a single lightly loaded host represents. Telemetry volume is driven by estate size, monitored technologies, and traffic that generates traces; a single lightly loaded test host understates all three. The option saying test hosts report telemetry at a different resolution from production hosts is incorrect because collection resolution is a configuration matter, not an inherent difference between environments. The option saying sizing depends only on the number of Instana interface users is incorrect because interface users are a minor factor beside continuous ingest. The option saying test environments are excluded from sizing calculations by product documentation is incorrect because test environments can inform sizing; the problem is extrapolating from an unrepresentative sample. For the exam, size from estate scale, technology mix, and trace volume.
