SCS-C02 Data Protection Practice Question
A company needs to ensure that data in transit between an EC2 instance and an RDS database is encrypted. Which solution meets this requirement?
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 SSL/TLS on the database connection
SSL/TLS is the appropriate solution to encrypt data in transit between the EC2 instance and the RDS database. It ensures that data is encrypted during transmission, preventing eavesdropping or tampering. Option A is incorrect because a VPN connection encrypts traffic between networks but is unnecessary for direct connectivity within the same VPC; SSL/TLS is more straightforward. Option B is incorrect because encryption at rest protects data stored on disk, not data in motion. Option D is incorrect because client-side encryption would require modifying the application to encrypt data before sending, which does not guarantee encryption of the entire communication channel.
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 a VPN connection between the VPC and the database
Why it's wrong here
A VPN is not needed for traffic within a VPC.
- ✗
Enable encryption at rest on the RDS instance
Why it's wrong here
Encryption at rest does not protect data in transit.
- ✓
Enable SSL/TLS on the database connection
Why this is correct
SSL/TLS encrypts data in transit.
- ✗
Use client-side encryption on the application
Why it's wrong here
Client-side encryption requires application changes and is not a standard solution.
