CCSP Cloud Data Security Practice Question
A multinational corporation must comply with GDPR and local data residency laws. They are designing a cloud storage architecture that will store customer data in the EU region. However, to improve disaster recovery, they want to replicate data to a secondary region outside the EU. Which approach meets compliance requirements?
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
✓
Use same-region replication within the EU and disable cross-region replication
To comply with data residency laws, data must stay within the EU. Replicating to a non-EU region violates GDPR. Instead, they should replicate to another EU region or use encryption with customer-managed keys and ensure the key is stored in the EU.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use cross-region replication to a non-EU region but apply client-side encryption before upload
Why it's wrong here
Even with client-side encryption, the encrypted data leaving the EU may be considered a transfer of personal data, violating regulations.
- ✓
Use same-region replication within the EU and disable cross-region replication
Why this is correct
Same-region replication keeps data within the EU, complying with data residency requirements.
- ✗
Use cross-region replication to a US region and encrypt data with SSE-S3
Why it's wrong here
Replicating data outside the EU violates data residency laws regardless of encryption.
- ✗
Use cross-region replication to a non-EU region and rely on a Data Processing Agreement (DPA)
Why it's wrong here
A DPA does not override data residency laws; data must physically remain in the EU.
