dbt Labs dbt Analytics Engineering Certification Exam Sample Questions (Q265-Q270):

NEW QUESTION # 265
Is this materialization supported by Python models in dbt?
Ephemeral

A. Yes
B. No

Answer: B

Explanation:
dbt Python models support a limited set of materializations because they rely on execution within the data platform's Python compute engine (such as Snowpark for Snowflake, Dataproc for BigQuery, or Spark).
These engines require models to materialize into actual relations-tables or views-in order to persist the results of Python-based transformations.
The ephemeral materialization, however, is fundamentally incompatible with this behavior. Ephemeral models do not create relations in the warehouse; instead, dbt inlines their SQL logic directly into downstream models. Since Python models cannot be inlined (they execute Python code, not SQL), dbt does not allow ephemeral Python models. dbt requires Python model outputs to be materialized as either:
* table
* view
* incremental
Therefore, ephemeral is not supported for Python models, and attempting to configure a Python model as ephemeral will result in a compilation error.
The reason is straightforward: ephemeral logic depends on SQL compilation, while Python models depend on executing Python code in the data platform. Because these mechanisms are incompatible, dbt restricts Python models to relational materializations only.
Thus, the correct answer is No - ephemeral is not supported for Python models.

NEW QUESTION # 266
You assume two columns of type 'numeric' will always align in terms of precision and scale (number of decimal places). What's a key way to design your models and tests to be resilient even if this assumption changes?

A. Avoid relying on exact equality when comparing values from these columns.
B. Use explicit casting functions to enforce matching precision during calculations.
C. Write tests to compare the column metadata rather than their contents.
D. Always store all numeric values as strings to prevent these issues.

Answer: A,B

Explanation:
These strategies allow for flexibility with numeric comparisons, making your models less sensitive to changes in precision. C is a good idea but not a full solution. D is generally bad practice.

NEW QUESTION # 267
dbt Model Snippet:SQL

A. Checking that the date_part() function is compatible with your database-
B. Making sure the source table fct_orders contains the expected columns.
C. Ensuring the grains variable is defined in dbt_project.yml or a macro.
D. Validating that the column names generated by the Jinja loop would be valid SQL identifiers.

Answer: C

Explanation:
Compilation errors often mean undefined variables or incorrect Jinja syntax. The rest are potential issues but less likely to break at the compilation stage.

NEW QUESTION # 268
(Multiple Select)

A. Your development profile in dbt_projectyml has incorrect connection details.
B. Environment variables used for sensitive credentials are not set correctly in production.
C. Your production database has stricter data type constraints than development.
D. You have accidentally granted write permissions to the production data source during testing.

Answer: B,C

Explanation:
Explanation: A could reveal issues only present when interacting with the real production data. C is a common source of environment-specific errors. B would likely cause errors everywhere. D is a serious issue, but wouldn't cause a regular dbt run to fail differently.

NEW QUESTION # 269
A complex transformation in your dbt project pulls data from an external API. Due to rate limits, this API endpoint cannot be queried frequently in production. How could you handle development and testing of this transformation effectively?

A. Use environment variables to control API query frequency or switch between live and test data sources.
B. Utilize dbt snapshots to capture a static set of API data for use during development and testing.
C. Set up a development environment that utilizes a mock API to simulate external data.
D. All of the above could be part of a strategy.

Answer: D

Explanation:
A: Mocks enable testing without impacting the production API- B: Environment variables allow for flexible configuration. C: Snapshots provide static samples for testing in isolation.
