This CCSP practice question tests your understanding of cloud data security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A startup provides a cloud-based document collaboration platform. They store user-uploaded documents in a cloud object storage bucket. Compliance with data privacy laws requires that when a user deletes an account, all their documents must be permanently deleted within 30 days. The current process uses object versioning and lifecycle policies to expire objects after 30 days. However, during a recent audit, it was discovered that deleted user documents were still accessible via the bucket's previous versions for months after the deletion. The security team needs to ensure that all traces of a user's data are removed immediately upon account deletion. Which solution should be implemented?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a lifecycle policy to permanently delete current and previous object versions immediately after the user deletion request.
Option D is correct because object versioning in cloud storage (e.g., AWS S3) retains both current and previous versions of objects. A lifecycle policy that immediately expires both current and noncurrent versions upon user deletion ensures that all copies of the data are permanently removed, satisfying the 30-day compliance requirement. Without explicitly targeting previous versions, the default lifecycle policy only deletes current versions, leaving older versions accessible indefinitely.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure bucket policies to deny read access to all objects after the user deletion date.
Why it's wrong here
Does not delete objects; they are still accessible if policy is modified.
✗
Change the bucket's default encryption to use customer-managed keys and delete the key after 30 days.
Why it's wrong here
Objects remain even if key is deleted; they could be recovered with another key.
✗
Enable MFA Delete on the bucket to require additional authentication for deletions.
Why it's wrong here
Does not ensure timely deletion; versions remain.
✓
Use a lifecycle policy to permanently delete current and previous object versions immediately after the user deletion request.
Why this is correct
Ensures immediate removal of all versions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the misconception that lifecycle policies automatically delete all object versions, when in fact they require separate rules for current and noncurrent versions, and candidates may overlook the need to explicitly target previous versions.
Detailed technical explanation
How to think about this question
In Amazon S3, object versioning creates a unique version ID for each object modification, and a simple DELETE operation adds a delete marker without removing the underlying data. A lifecycle policy with an 'Expiration' action on current versions and a 'NoncurrentVersionExpiration' action on previous versions is required to permanently purge all traces. The 30-day compliance window can be met by setting the expiration to 0 days (immediate) or a specific number of days after the deletion request, ensuring no residual data remains.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
