A data analyst troubleshoots a dashboard every day for a week. Which of the following techniques best addresses how to validate the data moving forward?

Inquiring about structure changes is a reactive approach and doesn't provide a continuous, automated solution for validating data quality and accuracy, only for schema modifications.

Setting up monitoring alerts allows the analyst to be automatically notified when data quality issues, anomalies, or deviations from expected patterns occur, providing immediate insight into potential problems without manual daily checks, thus proactively validating data.

Reaching out to users daily is inefficient, burdens users, and is a reactive method that doesn't prevent issues or provide automated, systematic data validation.

Rebuilding the dashboard is an extreme and often unnecessary step, as the issue is likely with the underlying data or queries, not the dashboard's structure itself, and doesn't prevent future data validation issues.
