dbt Labs dbt Analytics Engineering Certification Exam 認定 dbt-Analytics-Engineering 試験問題 (Q128-Q133):

質問 # 128
You must exclude a specific model from being included in the generated documentation entirely. How would you achieve this?

A. Its not possible to exclude individual models; you can only exclude entire folders.
B. Use the enabled flag in your dbt_projectyml file to control model inclusion.
C. Add a dæs: {enabled: false} entry to the model's YAML configuration.
D. Remove all descriptions and tags associated with the model.

正解：B

解説：
The enabled flag in dbt_project.yml provides control over whether a model (or other resources) are includedin dbt operations, including doc generation. Check your dbt version documentation for the latest syntax

質問 # 129
You want to standardize descriptions across a large number of models that share the same underlying source schemas. Which approach might be the most efficient?

A. Focus on using a version control system and enforce descriptions directly within the source system.
B. Create a CSV lookup file and maintain custom source descriptions within the file.
C. Write a Jinja macro that dynamically generates descriptions based on metadata.
D. Manually copy and paste the descriptions into each model's YAML file.

正解：C

解説：
Jinja macros offer flexibility and automation, making them ideal for generating consistent descriptions across many models based on source metadata

質問 # 130
You run a dbt job that heavily utilizes CT Es (Common Table Expressions). In your development environment, it works flawlessly. However, in production (a different database technology), it throws errors. Which potential causes should you investigate?

A. Your production environment has resource constraints that impact the execution of complex queries.
B. This indicates a bug in dbt's cross-database compatibility layer.
C. CTE performance optimizations are automatically applied in development, but not in production.
D. The production database has limitations or different syntax conventions related to CTEs.

正解：A、D

解説：
Acan lead to different behavior under load. B different dialects have nuances about CTE support C is unlikely, D less probable than a dialect-specific issue.

質問 # 131
External Dependency

A. Implement schema tests for the affected models to catch similar breakages immediately in the future.
B. Introduce a temporary staging model to transform the data into a compatible structure for your existing models.
C. All of the above.
D. Work with stakeholders to understand if the external change is intentional and adjust the business logic if needed.

正解：C

解説：
This requires adaptation, proactive future detection, and possible requirements adjustment since you can't fix what's not in your control.

質問 # 132
You want to include a multi-paragraph description for a source. Which of the following approaches is the most suitable?

A. Utilize YAML's block scalar syntax (using l) to maintain formatting for multi-line descriptions.
B. dbt documentation does not support multi-paragraph descriptions for sources.
C. Write a longer description directly within the YAML file, breaking it across multiple lines.
D. Reference an external Markdown file within the source description.

正解：A

解説：
The block scalar syntax in YAML allows for writing multi-line text blocks that preserve the original formatting
