CISA Practice Question: Which THREE are commonly used techniques to…
Which THREE are commonly used techniques to protect sensitive data in a cloud environment? (Select exactly 3.)
⚠ Common exam trap
ISACA often tests the distinction between data protection techniques (like encryption, tokenization, and masking) and general security controls (like network segmentation or code obfuscation), leading candidates to mistakenly select network segmentation as a data protection method.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Tokenization of sensitive fields.
Tokenization replaces sensitive data (e.g., credit card numbers) with a non-sensitive placeholder (token) that has no exploitable value. This technique is commonly used in cloud environments to reduce the scope of compliance (e.g., PCI DSS) because the token can be stored and processed without exposing the original sensitive value, even if the cloud storage is compromised.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Code obfuscation for application logic.
Why it's wrong here
Protects code, not data.
- ✗
Network segmentation between tiers.
Why it's wrong here
Network control, not data protection.
- ✓
Tokenization of sensitive fields.
Why this is correct
Replaces sensitive data with tokens.
- ✓
Encryption at rest and in transit.
Why this is correct
Standard data protection.
- ✓
Data masking for non-production environments.
Why this is correct
Hides sensitive data in test systems.
