Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Restricting backup service account permissions
Why this is correct
Least privilege prevents ransomware from accessing and deleting backups.

Storing backups on the same server as the primary data
Why it's wrong here
This makes them vulnerable to the same malware infection.

Using immutable storage solutions
Why this is correct
Immutability prevents any modification to the backup data.
- ✗
Using an easy-to-guess password for the backup drive
Why it's wrong here
