DP-300 Practice Question: Monitor, configure, and optimize database resources
Which THREE factors should you consider when configuring automatic tuning for an Azure SQL Database? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Whether to allow automatic index dropping.
The correct answers are B, D, and E. Automatic tuning for Azure SQL Database includes the options 'CREATE INDEX' (option E), 'DROP INDEX' (option B), and 'FORCE LAST GOOD PLAN' (option D). Option A (automatically creating plan guides) is not part of automatic tuning; plan guides are a manual feature. Option C (automatic statistics update) is a separate maintenance operation and not an automatic tuning option. Therefore, when configuring automatic tuning, you should consider enabling or disabling index creation, index dropping, and forcing the last good plan to address query plan regressions.
