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
✓
Step 1: Identify the backup, Step 2: Create a new Cloud SQL instance, Step 3: Restore the backup to the new instance, Step 4: Redirect applications to the new instance.
Restoring to an existing instance may overwrite data; best practice is to restore to a new instance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Step 1: Identify the backup, Step 2: Create a new Cloud SQL instance, Step 3: Restore the backup to the new instance, Step 4: Redirect applications to the new instance.
Why this is correct
This is correct because restoring to a new instance prevents overwriting production data, and creating the instance before restoring ensures the target exists. Redirecting after restore ensures minimal downtime.
- ✗
Step 1: Identify the backup, Step 2: Restore the backup to the existing instance, Step 3: Verify the data, Step 4: Redirect applications if needed.
Why it's wrong here
This is incorrect because restoring directly to the existing instance overwrites current data, risking data loss. Best practice is to restore to a new instance first.
- ✗
Step 1: Create a new Cloud SQL instance, Step 2: Identify the backup, Step 3: Restore the backup to the new instance, Step 4: Redirect applications.
Why it's wrong here
This is incorrect because you must identify the backup before creating the instance, as the backup determines the required instance configuration (e.g., region, size). Ordering creation before identification is inefficient.
- ✗
Step 1: Identify the backup, Step 2: Redirect applications to a new instance, Step 3: Restore the backup to the new instance, Step 4: Verify the restoration.
Why it's wrong here
This is incorrect because redirecting applications before restoring data causes downtime or errors (applications connect to an empty instance). Restoration must complete before redirecting.
