AWS Certified Developer Associate DVA-C01 – Question169

A company needs an event-management platform to accept registrations for an upcoming event. The platform must perform a single invocation of an existing AWS Lambda function 10 minutes after a user completes a new account registration.
Which solution will meet these requirements?

A.
Add an item to an Amazon DynamoDB table. Set the item TTL to 10 minutes. Invoke the Lambda function when the TTL expires.
B. Create an ongoing Amazon EventBridge (Amazon CloudWatch Events) rule with a rate expression of 600 seconds. Create a rule/target to invoke the Lambda function.
C. Send a message to an Amazon Simple Queue Service (Amazon SQS) delay queue. Set the queue to 600 seconds. Configure the Lambda function with the queue as an event source.
D. Put a record in Amazon Kinesis Data Streams. Configure the Lambda function to use the data stream as an event source. Define the shard iterator AT_TIMESTAMP setting to 10 minutes.

Correct Answer: B
