Question 520
A fleet monitoring platform must handle streaming ingestion failures. The current environment exhibits the following problem: a KQL aggregate is unexpectedly doubled after retry storms. Which technical choice fits this evidence?
Explanation
Correct Answer
Deduplicate by stable event identity before publishing metrics. Repeated delivery can distort counts unless deduplicated.
Incorrect Answers
Eventstream reports valid source input but no destination output. Source acceptance doesn't guarantee target delivery.
Events lack required timestamps and event-time windows return empty results. Windowing depends on valid event-time values.
A Spark streaming query fails with checkpoint corruption warnings. Stream restart state must remain consistent with source offsets.
