Quick Answer
The answer is customer account numbers and credit card information. Under PCI DSS, restricted data classification applies specifically to cardholder data elements that require the highest level of protection, including primary account numbers (PANs), expiration dates, and CVV codes, because the standard mandates encryption at rest and in transit, strict access controls, and regular security audits for this data. On the Certified Cloud Security Professional CCSP exam, this concept tests your ability to distinguish between sensitive and non-sensitive data categories within a cloud environment, often presenting a trap where public marketing materials or internal emails are mistakenly classified as restricted. A reliable memory tip is to remember that PCI DSS restricted data always ties directly to payment card processing—if it can be used to complete a transaction or commit fraud, it belongs in the restricted bucket.
This CCSP practice question tests your understanding of cloud data security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 cloud architect is designing a data classification scheme for a financial services firm. The data includes public marketing materials, internal emails, customer account numbers, and credit card information. Which two data categories should be classified as 'restricted' under PCI DSS and other regulations?
Public marketing materials
Why wrong: Incorrect: These are public and not restricted.
Credit card information
Correct: Credit card information is subject to PCI DSS and must be classified as restricted.
Internal emails
Why wrong: Incorrect: Internal emails may be confidential but are not automatically restricted.
Customer account numbers
Correct: Customer account numbers are sensitive and require protection under PCI DSS.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Credit card information
Credit card information (Option B) is classified as 'restricted' because PCI DSS explicitly mandates strict controls for cardholder data, including primary account numbers (PANs), expiration dates, and CVV codes. This data requires encryption at rest and in transit, access controls, and regular security audits to comply with the Payment Card Industry Data Security Standard.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
ISC2 often tests the misconception that all internal communications (like emails) are automatically 'restricted' under PCI DSS, when in fact only data containing specific regulated elements (e.g., PANs, SAD) qualifies for that classification.
Detailed technical explanation
Under PCI DSS, 'restricted' data includes cardholder data (CHD) and sensitive authentication data (SAD), where SAD (e.g., full magnetic stripe data, CVV2) must never be stored after authorization. In practice, tokenization or truncation of PANs is often used to reduce the scope of PCI compliance, but the original PAN remains restricted if stored. A real-world scenario: a cloud architect might use AWS Key Management Service (KMS) with envelope encryption to protect credit card numbers in a database, ensuring that only authorized applications can decrypt the data.
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.
