Varun's response starts with a relevant step of checking database keys and status, which is a good initial check. However, the response quickly moves to the suggestion of editing the code, which should not be the first resort in troubleshooting. Varun could improve by outlining a more structured and methodical approach to troubleshooting, such as verifying data sources, reviewing logs for errors, checking network connectivity, and using monitoring tools before considering code changes, as described in the benchmark response.
