A data platform team is designing a monitoring system for a data lake that receives files from multiple external vendors. The vendors have different data quality levels. The team wants to track the quality of each vendor's data over time and be alerted when a vendor's data quality drops below an acceptable threshold. Which monitoring approach best supports this requirement?

Profile each incoming file and calculate vendor-specific quality scores, then compare each score to a rolling baseline for that vendor

Manually review a sample of files from each vendor on a quarterly basis

Only monitor the total number of files received per day

Apply a single global quality threshold to all files regardless of vendor
