AWS Certified Developer Associate DVA-C02 Practice Question

Your application running on AWS Lambda is designed to process transactions and write logs to Amazon CloudWatch. You have noticed that the logs are difficult to search through when troubleshooting issues due to inconsistent formatting. To improve this, you decide to implement structured logging. Which approach would ensure that your logs are consistent and easily queryable?

  • Adopt XML formatted logs, where each entry is structured with relevant data tags.

  • Log the output as comma-separated values (CSV) with consistent ordering of information for each entry.

  • Format all log entries as JSON with consistent key-value pairs for each type of log message.

  • Use plain text logs with clear and consistent prefixes for each line.
