Correct answer & explanation
✓
Enable encryption at rest using a customer-managed key
Encryption at rest using a customer-managed key is the most important security configuration because it directly protects sensitive financial data stored in the database. Even if the underlying storage is compromised, the data remains unreadable without the key. Customer-managed keys provide additional control and help meet compliance requirements. While automated patching (B) is important for overall security, it does not protect data at rest. Public read access (C) should be disabled, not enabled, as it would expose sensitive data. Cross-region replication (D) ensures disaster recovery and availability, but does not address data confidentiality.
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 encryption at rest using a customer-managed key
Why this is correct
Encryption at rest protects data from unauthorized access to storage media.
- ✗
Configure automated patching schedule
Why it's wrong here
Patching addresses vulnerabilities but encryption is more fundamental for data protection.
- ✗
Enable public read access for monitoring tools
Why it's wrong here
Public access increases attack surface; monitoring should use private endpoints.
- ✗
Set up cross-region replication for high availability
Why it's wrong here
Replication is for availability, not data security.
