The answer is to ensure all client applications use the DynamoDB HTTPS endpoint. This configuration is correct because DynamoDB inherently enforces encryption in transit for all API calls, meaning HTTPS is mandatory and cannot be disabled or replaced with HTTP. The service uses TLS to encrypt data between the client and the AWS API endpoint, so simply pointing any SDK or CLI tool to the HTTPS URL guarantees that all access is encrypted. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding that DynamoDB does not offer a client-side SSL toggle or alternative transport—HTTPS is the only option. A common trap is assuming you need to configure VPC endpoints or CloudFront for encryption, but those are unrelated to the core HTTPS requirement. Memory tip: think of DynamoDB as “always on HTTPS”—there is no switch to flip, just use the correct endpoint.
DBS-C01 Database Security Practice Question
This DBS-C01 practice question tests your understanding of database security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 security engineer needs to ensure that all access to an Amazon DynamoDB table is encrypted in transit. Which configuration achieves this?
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.
Option B is correct because DynamoDB enforces HTTPS for all API calls, ensuring encryption in transit. Option A is wrong because DynamoDB does not support client-side SSL configuration. Option C is wrong because VPC endpoints use AWS PrivateLink but still require HTTPS. Option D is wrong because CloudFront is a CDN, not for database access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
