Question 490
An Eventhouse KQL transformation enriches native event streams. The current environment exhibits the following problem: an external accelerated shortcut is selected as the target of an update policy. Which action should the team take next?
Explanation
Correct Answer
Use a supported native KQL target instead of a shortcut. External acceleration doesn't supply native update-policy target behavior.
Incorrect Answers
A new update policy fails when its source/target schema mismatch. Update-policy output must conform to destination schema.
The same device has multiple lookup rows and the join multiplies counts. Nonunique lookup keys inflate event metrics.
Raw requests contain a device ID that needs a region lookup. Enrichment adds contextual fields without changing business event identity.
