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 developer accidentally uploaded a file containing API credentials to a public cloud storage bucket. The cloud provider states they cannot guarantee deletion of the object. Which practice could have prevented this incident?
Data loss prevention for cloud storage
DLP can inspect and block uploads containing sensitive data.
Bucket versioning
Why wrong: Versioning helps recover deleted data but does not prevent the upload.
Access control lists
Why wrong: ACLs control who can access, but the data remains in the bucket.
Server-side encryption
Why wrong: Encryption does not prevent unauthorized data from being stored.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Data loss prevention for cloud storage
Data Loss Prevention (DLP) for cloud storage can automatically scan objects for sensitive content, such as API credentials, before or after upload. When configured with policies to block or quarantine files containing patterns like access keys, DLP prevents the data from ever being stored in a public bucket, eliminating the risk even if the provider cannot guarantee deletion. This proactive control addresses the root cause—sensitive data exposure—rather than relying on post-incident remediation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Server-side encryption
Why it's wrong here
Encryption does not prevent unauthorized data from being stored.
Common exam traps
ISC2 often tests the distinction between preventive controls (DLP) and detective/reactive controls (versioning, encryption, ACLs), leading candidates to choose bucket versioning because it allows rollback, but versioning does not prevent the initial exposure of sensitive data.
Detailed technical explanation
Cloud DLP services (e.g., AWS Macie, Google Cloud DLP, Azure Purview) use pattern matching, machine learning, and context analysis to detect secrets like AWS Access Key IDs (e.g., AKIAIOSFODNN7EXAMPLE) or OAuth tokens. In a real-world scenario, a developer might accidentally upload a .env file containing database credentials; DLP can be configured to scan all PUT requests and trigger an alert or block the upload via a Cloud Storage API hook, such as AWS S3 Object Lambda or GCP Cloud Function triggered by Object Finalize events.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
