Data Analysis
A report must show 'Unknown' wherever the region value is NULL, without changing the stored data. Which SQL function does this?
COALESCE(region, 'Unknown')
SUM(region)
DATEDIFF(region, 'Unknown')
COUNT(region)
A
COALESCE returns the first non-null argument, so NULL regions display as 'Unknown' while other values pass through unchanged. SUM and COUNT are aggregates, and DATEDIFF calculates the interval between two dates.

About this course

These practice tests are for data analysts, business intelligence and reporting staff, and IT professionals moving into data roles preparing for the CompTIA Data+ (DA0-002) exam, which replaced DA0-001. They are also a quick way to move from DA0-001 study material to the current objectives.

You get 6 full-length practice tests with 90 questions each, 540 questions in total, sized like the real exam, and the sixth test runs in timed exam mode. Every question explains why the right answer is right and why the others are wrong, includes a hint, and is mapped to one of the five official DA0-002 domains. The series was rebuilt for DA0-002: every answer key was checked against the official objectives, repeats and retired DA0-001 topics were removed or rewritten, and 93 new questions cover areas such as AI concepts, cloud storage, query optimization, data transformation, troubleshooting, report validation, GDPR and data quality testing.
