This CCSP practice question tests your understanding of cloud data security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 financial services company is migrating to the cloud and must retain transaction records for seven years for regulatory compliance. They plan to use object storage with lifecycle policies. What is the most secure configuration for long-term data retention?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable object lock with retention mode set to compliance
Option B is correct because Object Lock with compliance retention mode provides the strongest guarantee against data modification or deletion, even by root users. This mode ensures that once an object is written, it cannot be overwritten or deleted until the retention period expires, which is critical for meeting the seven-year regulatory retention requirement. Unlike other options, compliance mode enforces a legal hold that cannot be removed by any user, including cloud administrators, making it the most secure configuration for immutable long-term retention.
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 a lifecycle policy to transition to archive storage after seven years
Why it's wrong here
Lifecycle policies can be altered and do not enforce deletion prevention.
✓
Enable object lock with retention mode set to compliance
Why this is correct
Compliance lock prevents any deletion or modification until the retention period expires.
Related concept
Read the scenario before looking for a memorised answer.
✗
Store objects in write-once-read-many (WORM) storage class
Why it's wrong here
WORM is not a built-in storage class; object lock is needed.
✗
Use server-side encryption with KMS key
Why it's wrong here
Encryption does not prevent data deletion.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between data protection mechanisms (encryption, lifecycle policies) and data immutability (Object Lock with compliance mode), leading candidates to choose encryption or archive transitions as sufficient for retention requirements.
Detailed technical explanation
How to think about this question
Object Lock with compliance retention mode works by applying a retention period at the object or bucket level, and once set, the retention date cannot be shortened or removed by any user, including the root account. Under the hood, the cloud provider's metadata system enforces this by rejecting any DELETE or PUT requests that would modify or remove the object until the retention period expires, even if the request is authenticated with full administrative privileges. In a real-world scenario, a financial auditor could verify that records are immutable by checking the object's retention mode and expiration date in the cloud provider's audit logs, ensuring compliance with SEC Rule 17a-4 or similar regulations.

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.
