Answer choices

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the Intelligent Insights root cause analysis report.
Intelligent Insights provides a root cause analysis report that can help identify the issue. Option A is wrong because scaling up should only be done after identifying the root cause. Option B is wrong because checking wait statistics is lower-level; Intelligent Insights already provides a diagnosis. Option C is wrong because Query Store may not be enabled by default and is not the first step.
