Sunil's response lacks depth and clarity. While he mentions checking network connectivity and system compatibility, he does not provide a structured approach to diagnosing and resolving the issue. The benchmark response outlines a detailed process, including identifying error messages, checking compatibility, rolling back updates, and reviewing logs. Sunil could improve by detailing specific steps, such as reviewing error codes and logs, and considering rollback options. This would demonstrate a more comprehensive understanding of troubleshooting failed updates.
