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
✓
Test the upgrade on a separate non-production environment first.
Options B and D are correct. Testing the upgrade on a separate non-production environment first (B) is a best practice to verify compatibility and avoid issues. Scheduling the upgrade during the maintenance window (D) allows Amazon RDS to perform the upgrade automatically with a failover, minimizing downtime. Option A is incorrect because disabling Multi-AZ would eliminate the failover benefit and cause downtime. Option C is incorrect because minor version upgrades do not require modifying the DB parameter group; AWS RDS handles parameter compatibility automatically. Option E is incorrect because taking a snapshot is a good practice for recovery but does not reduce downtime during the upgrade.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable Multi-AZ before the upgrade to reduce complexity.
Why it's wrong here
Disabling Multi-AZ would cause downtime and is not recommended.
- ✓
Test the upgrade on a separate non-production environment first.
Why this is correct
Testing ensures compatibility and reduces risk of issues during the production upgrade.
- ✗
Modify the DB parameter group to set the new version parameters.
Why it's wrong here
Minor version upgrades do not require parameter group changes; the new version inherits compatible parameters.
- ✓
Schedule the upgrade during the maintenance window.
Why this is correct
RDS applies minor version upgrades during the maintenance window, which includes a failover with minimal downtime.
- ✗
Take a snapshot of the DB instance before the upgrade.
Why it's wrong here
While a snapshot is good for backup, it does not reduce downtime during the upgrade.
