Question 580
A Real-Time dashboard is displaying yesterday's readings even though its underlying event source is active. What should the engineer check to confirm that the intended behavior was achieved?
Explanation
Correct Answer
Source and presentation tests isolate the layer. This observation directly tests the expected outcome.
Incorrect Answers
A live DMV record establishes the query-level bottleneck.
An injected threshold case validates the alert.
Reconciliation validates ingestion completeness. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: Current events exist in the database and appear after the dashboard time filter is corrected.
