Why does running synthetic tests from selected locations matter?
Select an answer to reveal the explanation.
Short Explanation
You test from selected locations because availability and performance change with network path and region. A regional CDN failure or routing problem can be invisible from the wrong continent. Where you test from is part of what you're testing.
Full Explanation
The correct answer says availability and performance vary by network path and region, so testing from where users are reveals problems a test elsewhere would not see. Users reach a service across specific networks and regions. Regional outages, DNS differences, and CDN behaviour produce failures visible only from the affected location.
The option claiming Instana requires at least three locations before a test can be saved is incorrect because there is no such minimum; one location is valid, though usually insufficient.
The option saying location selection determines retention is incorrect because retention is governed by policy rather than test origin.
The option asserting tests from different locations produce identical results is incorrect because differing results are exactly what this feature exists to expose.
For the exam, connect location selection to where users actually are.
