The administrator ' s goal is to gain a better understanding of current data quality and record completeness issues in Accounts and Opportunities. Creating reports (or dashboards) that highlight blank or missing key fields—using filters like " Field equals (blank) " or formula fields to flag incompleteness—directly assesses the existing data by showing which records lack required information.

Why B is correct : Salesforce Trailhead modules on data quality emphasize using reports and dashboards (e.g., Account, Contact & Opportunity Data Quality Dashboard) to identify missing fields and measure completeness before implementing fixes.

Why not the others :

A : Exploring AppExchange apps is useful for advanced or ongoing solutions but skips the initial assessment step.

C : Subscribing reps to reports helps with awareness but doesn ' t provide the admin with an overview of data quality.

D : Making fields required prevents future issues but doesn ' t reveal current missing data or outdated records.

This approach aligns with Salesforce best practices: assess data quality first through reporting, then enforce improvements.
