Question 1 of 30

A seasoned data architect is overseeing a critical migration of a terabyte-scale relational data warehouse to Snowflake. Post-migration, several key ETL pipelines, previously running efficiently, are now exhibiting significant performance bottlenecks, impacting downstream business intelligence reporting. The architect must swiftly diagnose and rectify these issues with minimal disruption to the production environment, considering the tight regulatory compliance deadlines for data availability. Which of the following diagnostic and resolution strategies would be most appropriate to implement first?

Conduct a comprehensive review of the Snowflake query history and warehouse load metrics to identify the most resource-intensive queries and periods of high warehouse utilization, subsequently optimizing problematic SQL statements and re-evaluating warehouse sizing based on observed workload patterns.
Immediately scale up the Snowflake virtual warehouse to the largest available size and implement aggressive auto-scaling policies, assuming the issue is purely a compute resource limitation.
Initiate a rollback of the migration to the legacy system while simultaneously filing a support ticket with Snowflake, prioritizing system stability over immediate resolution on the new platform.
Focus on re-indexing all tables within the Snowflake environment and re-writing all ETL scripts from scratch using a different data loading pattern, without initial performance profiling.
