DBS-C01 Database Security Practice Question
A security engineer needs to ensure that all access to an Amazon DynamoDB table is encrypted in transit. Which configuration achieves this?
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
✓
Ensure all client applications use the DynamoDB HTTPS endpoint.
DynamoDB uses HTTPS for all API calls by default, ensuring encryption in transit. Option A is incorrect because configuring a VPC endpoint does not enable encryption; it provides private connectivity, but encryption in transit is already handled by HTTPS. Option C is incorrect because placing DynamoDB behind CloudFront is not a valid configuration; CloudFront is a CDN for content delivery, not for securing database access. Option D is incorrect because DynamoDB does not have an 'ssl_enabled' parameter; encryption in transit is always enforced via HTTPS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a VPC endpoint for DynamoDB and enable encryption.
Why it's wrong here
VPC endpoints use HTTPS by default, but the key is that clients must use HTTPS endpoints.
- ✓
Ensure all client applications use the DynamoDB HTTPS endpoint.
Why this is correct
All DynamoDB requests must be made over HTTPS; this is the only way to encrypt data in transit.
- ✗
Place the DynamoDB table behind Amazon CloudFront.
Why it's wrong here
CloudFront is not used to access DynamoDB directly.
- ✗
Enable SSL on the DynamoDB table by setting the 'ssl_enabled' parameter.
Why it's wrong here
DynamoDB does not have such a parameter; it always uses HTTPS.
