- A
Pseudonymization
Correct: Pseudonymization replaces identifiers with consistent pseudonyms, preserving relationships.
- B
Bucketing
Why wrong: Bucketing generalizes data into ranges, not suitable for realistic replacement.
- C
Masking
Why wrong: Masking obscures parts of data, not suitable for generating realistic fictitious data.
- D
Tokenization
Correct: Tokenization can maintain referential integrity if tokens are deterministic.
- E
Date shifting
Why wrong: Date shifting moves dates, not a general replacement for sensitive values.

CCSP Cloud Data Security Practice Question
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 security team is evaluating DLP techniques to protect sensitive data in a cloud data warehouse. They want to replace sensitive values with realistic but fictitious data for non-production environments while preserving referential integrity. Which TWO de-identification techniques are suitable?
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
✓
Pseudonymization
Tokenization replaces sensitive data with a token that can be consistent across tables, preserving referential integrity. Pseudonymization replaces identifiers with consistent pseudonyms, also preserving relationships.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related CCSP subnetting questions on CIDR, address ranges, and subnet selection.
