- A
Enable server access logs for the storage bucket
Logs provide audit trail of all access requests.
- B
Use default server-side encryption with cloud-managed keys
Why wrong: Encryption does not enforce geographic storage location.
- C
Enable cross-region replication for disaster recovery
Why wrong: Cross-region replication would copy data to another region, violating residency.
- D
Configure bucket policies to deny access from outside the allowed region
Bucket policies can restrict access based on geographic location of the request.
- E
Implement VPC Service Controls to create a data perimeter
VPC Service Controls restrict data movement across boundaries.

CCSP Cloud Data Security Practice Question
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 financial institution is migrating to the cloud and must comply with regulations requiring that sensitive data be stored only in specific geographic regions and that access to data is logged and monitored. Which THREE controls should be implemented? (Select THREE.)
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
✓
Enable server access logs for the storage bucket
To enforce data residency, the cloud region must be restricted via IAM or organization policies. Server access logging captures all requests to storage. VPC Service Controls create a security perimeter around cloud resources, preventing data exfiltration. Cross-region replication would violate residency, and default encryption is not sufficient.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable server access logs for the storage bucket
Why this is correct
Logs provide audit trail of all access requests.
Related concept
Standard ACLs match source addresses.
- ✗
Use default server-side encryption with cloud-managed keys

Implement VPC Service Controls to create a data perimeter
Why this is correct
VPC Service Controls restrict data movement across boundaries.
Related concept

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related CCSP ACL questions on filtering logic and placement.
