"We can just load everything into our warehouse and let dbt handle it." How would you respond to this approach suggested by a stakeholder?
A. It could become expensive due to storage and compute costs, especially with large, raw datasets.
B. Introducing sensitive data sources requires careful consideration and might be better handled outside the warehouse.
C. All of the above.
D. dbt models might become unnecessarily complex due to unfiltered data.

質問 2：
You need to grant readonly access to a new stakeholder on a specific dbt model's output. What factors should influence your approach?
A. The database technology and its permissions model.
B. The default materialized setting defined for models in your dbt_project_yml file.
C. If this is a one-time need, or something requiring scalable permission management.
D. Whether you wish to provide direct table access or a view-based interface.

質問 3：
(Multiple Select)
A. Apply an incremental materialization strategy to subsequent models if appropriate.
B. Introduce a source snapshot to create a point-in-time copy of the data.
C. Increase the query_comment timeout setting in your dbt_project. yml

質問 4：
You're onboarding new developers to your dbt project. To simplify their setup, you want to provide a standard profiles.yml template. What should you consider when doing this?
A. Referencing environment variables to allow for easy customization by developers.
B. Providing example dbt commands as comments directly within the file to guide new users.
C. Prepopulating common credentials to make the initial setup hassle-free.
D. Including different target configurations to illustrate switching between development and production.

質問 5：
You've defined development, staging, and production targets in your dbt project. You want to prevent accidental execution of destructive model materialization strategies (like drop or truncate) on the production target. How could you achieve this?
A. Rely purely on thorough code reviews to prevent execution of these commands in production.
B. Create a separate profiles.yml file for production that disables dangerous materialization strategies.
C. Write a custom macro that only executes such operations on non-production targets.
D. Implement a CI/CD process that includes checks to prevent specific dbt commands from running in the production environment
