Chapter 1 in full: Prepare the data
28% of the exam, about 14 questions. These are its key points, as in the guide.
- Connect using the correct source connector; document credentials and privacy requirements before combining sources.
- Choose storage from requirements: Import stores a copy, DirectQuery queries a source, and Direct Lake is a Fabric-specific option. Check feature prerequisites rather than assuming all sources support all modes.
- Profile the relevant dataset scope before fixing errors. Distinguish null values, conversion errors and business-rule violations.
The rest of chapter 1, on this page
- Set data types deliberately and check locale when parsing dates or decimal separators. Keep the original values until you have validated the result.
- Use grouping to aggregate rows. Pivot creates columns from categories; unpivot turns repeated attribute columns into attribute-value rows.
- Merge combines tables using matching keys and a join kind. Append stacks rows; verify column names and compatible types.
- Build fact and dimension queries at a defined grain. Compare reference versus duplicate queries and turn off model loading for staging queries when appropriate.
Common mistakes in this chapter
- Do not remove every error row before checking whether the error reveals a source or locale problem.
- Append is not a key-based join. A reference query is not a guaranteed cached materialisation of its upstream result.
