CCSP Object immutability Practice Question
A small business uses a cloud file storage service to share project files with external partners. They have enabled versioning on the bucket, and each partner has a unique folder. The security team discovers that a former employee, who had administrative access, deleted all files in a partner's folder and then deleted the folder. The bucket's versioning allows restoration of the files, but the folder deletion cannot be undone. The business wants to prevent similar incidents in the future while still allowing external partners to upload and download files. Which approach should be taken?
⚠ Common exam trap
CCSP often tests the distinction between multifactor authentication for deletion (which only adds an authentication step but does not prevent deletion by authorized users) and object immutability (which provides immutable protection against deletion or overwrites).
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
✓
Use object immutability to prevent object deletion or overwrites.
Object immutability prevents any object from being deleted or overwritten by any user for the specified retention period. This directly addresses the requirement to prevent file deletion while still allowing partners to upload and download files, as versioning remains enabled and folder structure can be recreated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use access policies to prevent deletion of objects by anyone except a specific admin group, and use lifecycle policies to manage temporary files.
Why it's wrong here
Access control policies can restrict deletion to specific admin groups, but they do not prevent a malicious or compromised admin from deleting objects, so this does not fully address the requirement.
- ✓
Use object immutability to prevent object deletion or overwrites.
Why this is correct
Immutable storage policies, such as WORM, ensure that objects cannot be deleted or overwritten during the retention period, providing strong protection against deletion while allowing uploads and downloads.
- ✗
Enable multifactor authentication for deletion on the storage.
Why it's wrong here
MFA for delete adds an extra authentication step but does not prevent deletion by authorized users; it only adds a hurdle, not immutability.
- ✗
Disable versioning and implement a backup process.
Why it's wrong here
Disabling versioning removes the ability to restore deleted files, and a backup process may not provide the same granular recovery as versioning.
