DBS-C01 Database Security Practice Question
A company uses Amazon DynamoDB for its critical application. The security team requires that all access to DynamoDB tables be logged and monitored for suspicious activity. The company also needs to be alerted when a user deletes a table. Which combination of AWS services should be used?
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
✓
AWS CloudTrail and Amazon CloudWatch Events.
AWS CloudTrail logs all DynamoDB API calls, including DeleteTable, and can send events to Amazon CloudWatch Events, which can trigger alerts via SNS or Lambda. Option A is incorrect because DynamoDB Streams captures item-level changes, not API calls. Option B is incorrect because AWS Config records resource configuration changes but not API calls directly for alerting; CloudTrail is needed. Option D is incorrect because VPC Flow Logs capture network traffic, not API calls.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS CloudTrail and Amazon DynamoDB Streams.
Why it's wrong here
DynamoDB Streams capture data changes, not API calls like DeleteTable.
- ✗
AWS Config and Amazon Simple Notification Service (SNS).
Why it's wrong here
AWS Config tracks configuration changes but not every API call; it is not ideal for real-time alerting on DeleteTable.
- ✓
AWS CloudTrail and Amazon CloudWatch Events.
Why this is correct
CloudTrail logs API calls, and CloudWatch Events can create rules to match DeleteTable events and trigger alerts.
- ✗
Amazon VPC Flow Logs and Amazon CloudWatch Logs.
Why it's wrong here
VPC Flow Logs capture IP traffic, not DynamoDB API calls.
