The correct combination is a lifecycle policy and secure deletion. A lifecycle policy automates the management of cloud storage objects by defining rules for transitioning data to colder tiers and then expiring or deleting it after a set period—in this case, seven years. Secure deletion, achieved through methods like overwriting with random data or cryptographic erasure, ensures the data is irrecoverable after deletion, satisfying the regulatory mandate for secure destruction. On the Certified Cloud Security Professional CCSP exam, this scenario tests your understanding of how to align automated data governance controls with compliance requirements; a common trap is confusing data masking or access revocation with actual secure deletion, which only renders data unreadable, not irrecoverable. Remember that lifecycle policies handle the “when” and “how long,” while secure deletion handles the “how thoroughly.” A useful memory tip is “Lifecycle for the clock, secure deletion for the lock.”
CCSP Cloud Data Security Practice Question
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 company is designing a data retention policy for cloud storage. Regulatory requirements mandate that certain records be kept for 7 years and then securely destroyed. Which combination of controls should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Lifecycle policy and secure deletion
A lifecycle policy automates the transition and expiration of objects, allowing you to set a rule to delete objects after 7 years. Secure deletion (e.g., overwriting or cryptographic erasure) ensures the data is irrecoverable, meeting the regulatory requirement for secure destruction. Together, they provide a fully automated, auditable process for retention and destruction.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Read the scenario before looking for a memorised answer.
✗
Data masking and encryption
Why it's wrong here
Masking and encryption do not address retention and deletion.
✗
Versioning and MFA delete
Why it's wrong here
Versioning keeps versions; MFA delete adds extra protection but does not automate deletion.
✗
Lifecycle policy and object lock
Why it's wrong here
Object lock prevents deletion, not suitable for retention.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between 'preventing deletion' (object lock) and 'ensuring secure destruction' (secure deletion), leading candidates to choose object lock because it sounds like it handles retention, but it does not guarantee irrecoverable deletion after the retention period ends.
Detailed technical explanation
How to think about this question
In cloud storage services like Amazon S3, a lifecycle policy can be configured with an 'Expiration' action to delete objects after a specified number of days. Secure deletion often involves overwriting the storage blocks with zeros or using a cryptographic key shredding approach (e.g., AWS S3's 'DeleteMarker' with versioning disabled or using a secure wipe API). A real-world scenario is healthcare records under HIPAA, where lifecycle policies automate 7-year retention and secure deletion must ensure data is unrecoverable from underlying storage media.

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.
