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 uses a cloud-based file sharing service and wants to prevent sensitive data from being shared externally. Which cloud data security capability is most appropriate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scanning data at rest in cloud storage with DLP
Option C is correct because Data Loss Prevention (DLP) scanning of data at rest in cloud storage directly identifies and blocks sensitive content (e.g., PII, PCI-DSS data) stored in files before it can be shared externally. This capability is purpose-built for preventing unauthorized sharing by inspecting the actual content of files in the cloud repository, such as Amazon S3 or Azure Blob Storage, using pattern matching and fingerprinting.
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.
✗
Inspecting data in use within applications
Why it's wrong here
This is relevant for application-level DLP, not file storage.
✗
Monitoring network traffic for data exfiltration
Why it's wrong here
This detects data in transit, not preventing sharing of stored files.
✓
Scanning data at rest in cloud storage with DLP
Why this is correct
DLP scanning identifies sensitive data and can enforce policies to block external sharing.

✗
Encrypting data in transit
Why it's wrong here
Encryption protects confidentiality during transmission, not sharing controls.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between preventive controls (DLP at rest) and detective/monitoring controls (network traffic analysis), leading candidates to choose network monitoring because it sounds like 'data exfiltration prevention' but fails to address the sharing action itself.
Detailed technical explanation
How to think about this question
Cloud DLP engines, such as Google Cloud DLP or AWS Macie, use content inspection techniques like regex pattern matching (e.g., for credit card numbers per Luhn algorithm), keyword dictionaries, and machine learning-based classifiers to identify sensitive data. When integrated with cloud storage, DLP can automatically quarantine or redact files that match sensitive data profiles, enforcing policies at the object level (e.g., S3 bucket policies with deny effects). A real-world scenario is a healthcare organization using DLP to prevent sharing of PHI stored in cloud storage by scanning for HIPAA-defined identifiers like medical record numbers.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
