An analyst is profiling a new 'product' table and wants to understand the relationships between the 'category' column and the 'supplier' column to see if certain suppliers only provide certain categories. Which profiling technique should be used?

Key profiling to check if 'supplier' is a primary key

Cross-column profiling to examine the co-occurrence of values between the two columns

Data type profiling to verify both columns are strings

Single-column profiling to get the distinct value count for 'category'

A data quality report should document the nature of the issue, the affected data, and the potential impact. What is the primary purpose of documenting data quality issues?

To replace the need for data profiling

To enable tracking and resolution of issues

To comply with data privacy laws

A data quality monitoring system flags that the 'product_description' field in a product catalog has a high rate of missing values. The data team discovers that the missing values come from a new vendor feed that started last month. The team needs to decide how to handle this issue. Which action is the most appropriate first step?

Ignore the issue because it only affects the description field, which is not critical

Contact the vendor to understand why descriptions are missing and establish a data quality agreement

Immediately populate the missing descriptions with a default value like 'N/A'

Remove the new vendor feed from the catalog until the issue is resolved
