You run a new dbt job, but several models don't execute. Logs indicate: "Database Error in model. The error message seems unrelated to your recent model code changes. What's a possible non- SQL cause?

• A.You've accidentally deleted a source table that these models depend on.
• B.dbt's connection to the database has incorrect credentials or is encountering network issues.
• C.A macro used in multiple models has an error that prevents the models from compiling correctly.
• D.There's a configuration error in your project file causing dbt to skip certain models.

You have a complex dbt model that is essential for production reporting. To minimize the risk of breaking this model during development, what strategy might you employ?

• A.Configure production jobs to use a pinned version of the dbt model.
• B.Create a duplicate model in production and only sync changes once they're fully tested-
• C.Rely on your data warehouse's native rollback functionality to reverse changes if needed.
• D.Write extensive tests targeting this model in your production environment

A critical model fails with a non-descriptive error. You suspect a third-party package used in the model. How might you narrow down the problem?

• A.Examine recent commits or releases of the package for changes that might have introduced a bug.
• B.Run the package's models in isolation to see if the error reproduces.
• C.Add -log-format json to your dbt run command to get more structured error output.
• D.Temporarily disable the package and try running the model.

After adding several new models to your project, you want to execute only those models and their direct dependencies. Which command combination best achieves this?

• A.dbt build
• B.dbt run -exclude model namel model name2
• C.dbt run -models +model namel +model name2 ...
• D.dbt run followed by dbt test

You write a macro to dynamically create a filter string and apply it within a model as follows:SQL

• A.The generate_filter macro should be placed within a separate macros directory, not inline in the model.
• B.The database doesn't support comparison of the data type of the region column with a string value.
• C.You cannot dynamically apply filters using Jinja; they must be hardcoded in your model's SQL.
• D.The macro templating incorrectly nests single and double quotes.
