AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 59

A CloudOps engineer needs to build an event infrastructure for a set of custom application-specific events. The events must be sent to an AWS Lambda function for processing. The CloudOps engineer must record the events to replay later by event type or event time.
Which solution will meet these requirements?

Answer options

• A. Create an Amazon EventBridge custom event bus. Create an archive on the custom event bus. Create a rule to send the custom events to the Lambda function.
• B. Create an archive on the Amazon EventBridge default event bus. Use pattern matching to record the custom events. Create a rule to send the custom events to the Lambda function.
• C. Create an archive on the Amazon EventBridge default event bus. Create an EventBridge pipe to ingest the custom events and to save the custom events in the archive. Create a rule to send the custom events to the Lambda function.
• D. Create a log group in Amazon CloudWatch Logs. Create an Amazon EventBridge rule to send the custom events to the Lambda function and to the log group.

Correct answer: A

Explanation

Option A is correct because creating a custom event bus with an archive allows for the specific handling and recording of custom events, which can be replayed based on event type or time. The other options either use the default event bus, which may not provide the same level of customization, or involve unnecessary components that do not align with the requirement to replay events effectively.
