질문 # 243
(Multiple Select)

A. Scheduling models to run outside normal business hours to reduce resource contention.
B. Implementing more rigorous access controls and auditing procedures.
C. Potentially running on a different data warehouse or with different database settings.
D. Using credentials with appropriate permissions (likely read-only) to access production data sources.

정답：B,C,D

설명：
A reflects the increased security needs of production environments. B allows scaling or optimization based on workload. C prevents accidental changes in production. D is a strategy, but not a fundamental difference.

질문 # 244

정답：

설명：

Explanation:
Update int_order_items by replacing:
* {{ source('tpch', 'orders') }} # {{ ref('stg_tpch_orders') }}
* {{ source('tpch', 'lineitem') }} # {{ ref('stg_tpch_line_items') }}
In dbt's recommended modeling pattern, sources should be referenced only in the staging layer. Downstream models (intermediate and mart/fact models) should reference staging models via ref(), not the raw source() directly. This keeps all raw-to-clean logic centralized in the staging layer and makes refactoring and documentation easier.
In the original DAG, int_order_items depends directly on tpch.orders and tpch.lineitem via source(), and staging models also depend on those same sources. That creates parallel paths from the sources and breaks the clean layered architecture.
By updating the int_order_items SQL to use:
from {{ ref('stg_tpch_orders') }}
join {{ ref('stg_tpch_line_items') }} ...
instead of:
from {{ source('tpch', 'orders') }}
join {{ source('tpch', 'lineitem') }} ...
you ensure that int_order_items sits entirely downstream of the staging layer. The new DAG becomes linear: sources # staging # intermediate (int_order_items) # any further marts. This improves modularity, reusability of cleaned logic, and makes the DAG easier to reason about and maintain.

질문 # 245
You've configured your project to include both schema and data tests in the generated documentation. A user reports the tests are visible but don't show any execution results (pass/fail status). Why might this be happening?

A. The project settings are explicitly configured to hide test results in the documentation.
B. The documentation generator has a known limitation on how test results are displayed.
C. The type of test you're using is not supported for displaying results in the documentation.
D. Your data pipeline hasn't been executed recently, so there are no recent test results.

정답：A,D

설명：
A Test results depend on recent executions; if your data pipeline is not updated, there won't be fresh results. B: Its possible to have configurations that display the tests themselves but not their execution results

질문 # 246
You introduce a new data source for a dbt model. Production policies require review and approval of the source's schema before it can be used for reporting. How could you streamline this within your dbt project?

A. Write dbt tests that explicitly fail if the new source schema does not match the approved definition.
B. Run a separate dbt project in production exclusively for source validation, providing access to relevant stakeholders.
C. Use dbfs ephemeral models feature to temporarily load the data for the approval process.
D. Create a pre-hook that automates schema validation and sends the output to the designated team.

정답：B,C,D

설명：
A provides proactive checks integrated into the workflow. B establishes a self-contained validation environment. D is an easy, controlled way for review. C is reactive and could potentially halt valid deployments.

질문 # 247
While reviewing a dbt project, you notice a pattern where ref() calls are chained together:
Model A references Model B, which in turn references Model C.
What's a potential downside of this pattern?

A. Version control conflicts become more likely.
B. Decreased performance due to unnecessary materializations.
C. Model dependencies become harder to track and understand.
D. Test results might become less reliable.

정답：C

설명：
While chaining ref() calls works technically, it can quickly make dependency tracking overly complex, especially in larger projects.
