dbt Labs dbt Analytics Engineering Certification Exam dbt-Analytics-Engineering Prüfungsfragen mit Lösungen (Q191-Q196):

191. Frage
You've introduced a new series of dbt models and want to run them in isolation to verify results before integrating them into the main build process. Which dbt command options and flags are likely to be useful?

A. dbt run -s to target models with a specific tag
B. dbt build -exclude model_name to temporarily skip certain models.
C. dbt run -m +model_path to explicitly select a model by its file path.
D. dbt test --select source name to validate the new models' source data.

Antwort: A,C

Begründung:
A and C provide precise selection mechanisms. B is for exclusion, not focused execution- D is about tests, not model runs-

192. Frage
In what situations might it be acceptable to use raw data directly for reporting or analytics purposes?

A. When dealing with simple analyses, and there's high confidence in the quality of the raw data source.
B. When performance is a top priority, and the overhead of additional data transformations is undesirable.
C. Generally, using raw data directly for reporting should be avoided due to potential quality and consistency issues.
D. In environments where strict data governance and transformation processes are in place.

Antwort: C

Begründung:
Raw data is often unpredictable- However, under specific conditions like those listed in A, B, or C, it could be considered if the risks and trade-offs are well understood.

193. Frage
A colleague expresses confusion about how dbt uses the dbt_project.yml file. Which of the following is the MOST accurate high-level explanation?

A. The dbt_project. yml file serves as a temporary cache for in-development models.
B. The dbt_projectyml file acts as a blueprint for how dbt should generate your data models, tests, and documentation.
C. The dbt_project yml file contains the actual SQL code that defines your data transformations.
D. The dbt_project.yml file is primarily used for version control and collaboration in dbt projects

Antwort: B

Begründung:
Emphasize the configuration aspect of dbt_project.yml; it guides dbt's behavior but doesn't contain the SQL logic itself.

194. Frage
(Multiple Select)

A. The desired frequency for updating the data
B. The number of users currently active on the data warehouse.
C. Existing model patterns within the project for consistency.
D. The level of detail needed in downstream reporting.

Antwort: A,D

Begründung:
Reporting needs and data freshness requirements directly shape model design. Consistency (D) is important, but secondary to functional requirements- The number of active users is more relevant to database sizing

195. Frage
You're refactoring a dbt project with circular dependencies (e.g., Model A references Model B, which references Model A).
Select the most appropriate strategy:

A. Create snapshots to break the dependency chain.
B. Introduce a redundant intermediate model to resolve the circularity.
C. Add the -full-refresh flag to dbt run to force execution.
D. Rewrite SQL logic to remove the circular references.

Antwort: D

Begründung:
Circular dependencies are a fundamental design flaw. 'Snapshots' and -full-refresh are workarounds. Introducing redundant models creates maintenance overhead.
