De-identification transforms such as masking and tokenization
DLP can apply transforms to obscure sensitive data.

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.
An organization is implementing a data loss prevention (DLP) solution to protect sensitive data in cloud storage. Which TWO of the following are capabilities of a cloud DLP service? (Select TWO.)
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
✓
De-identification transforms such as masking and tokenization
Cloud DLP services can scan data for sensitive patterns (like credit card numbers) and apply de-identification transforms to redact or mask data. They do not manage encryption keys or automate backup.
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.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatic encryption key rotation
Why it's wrong here
Key rotation is a key management function, not DLP.

Enforcing multi-factor authentication
Why it's wrong here
MFA is an access control, not DLP.
- ✓
De-identification transforms such as masking and tokenization

Automated backup of sensitive data
Why it's wrong here
Backup is a separate function from DLP.
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 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.
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.
