Microsoft Security Operations Analyst Associate SC-200 Practice Question

For a scheduled query analytics rule, the most direct way to stop unwanted incidents for a particular source is to refine the rule's Kusto Query Language (KQL) statement. Adding a filter such as | where SubscriptionId != "SubDev" removes events from the development subscription before the rule evaluates its alert logic, so no alerts-or incidents-are produced for that subscription while the rule continues to run normally for the other subscriptions.

Creating an automation rule or playbook that closes incidents after they are raised does not prevent the alerts or incidents from being generated in the first place, so it does not meet the requirement to avoid creation. Microsoft Sentinel does not have an "incident suppression rule" or an alert-grouping setting that can selectively suppress incidents by subscription within a single rule; grouping only affects how incidents are consolidated, not whether they are created. Therefore, modifying the KQL query is the correct and most efficient approach.
