NO.214 You implement dbt tests to monitor data quality over time. Which of the following scenarios could these tests potentially help you detect?

Gradual degradation in source data completeness due to an API rate limit being reached

Performance issues in your data warehouse impacting the speed of dbt model updates.

An accidental schema change by someone working outside of your dbt project-

An unexpected spike in web traffic leading to invalid data entries in your source system-

A, C, and D relate to the changing quality of the data itself, which tests can surface. B (warehouse performance) is a separate issue.

NO.215 Type Mismatch

Modify the source table directly in the database to adjust the data type, ensuring backward compatibility.

Use a CAST operation within the affected model’s SQL, leaving the underlying source unchanged.

Introduce a staging model specifically to perform the type conversion, creating a clean separation.

Handle the type conversion with a custom macro and apply it selectively within your dbt project.

A staging model offers the most control and flexibility. Direct source modification risks disrupting other systems. In-model CASTs work but clutter the core logic. Macros are powerful but add complexity.

NO.216 You’re tasked with creating a model for audit purposes. The data must be preserved exactly as it was at a specific point in time. Update frequency is low, and there’s no need for additional transformations on the captured dat a. What materialization should you use?

Snapshot

Incremental

View

Table

Snapshots are designed for historical preservation. They capture the state of a source at a moment in time, providing a perfect audit trail.

NO.217 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?

dbt run followed by dbt test

dbt build

dbt run -models +model namel +model name2 …

dbt run -exclude model namel model name2

The + syntax with dbt run allows you to specify models and their upstream dependencies. Dbt build encompasses run and test along with snapshot execution.

NO.218 You get a warning during dbt run:WARNlNG: Found 100 rows in ‘stg_customers’ that will become duplicates in the ‘dim_customers’ target.

It’s safe to ignore this warning, as de-duplication is handled automatically by dbt.

Investigate your dim_customers modeling logic to ensure a unique key is correctly used to prevent duplicates.

Update the stg_customers source definition to include filtering logic to remove duplicate rows.

Increase the memory allocated for the database to handle the large number of duplicates.

This typically indicates a logic flaw in your model creating the target table. Modifying the source or increasing memory won’t resolve the core issue.

NO.219 (Multiple Select)

The technology used for your production data warehouse.

The cost-efficiency of the development environment solution.

The need for feature parity (functions, syntax) with the production warehouse.

The overall size and complexity of your dbt project

A ensures compatibility and consistent developer experience. B avoids excessive development costs. C prevents surprises when porting code- D influences the scale of resources you need in development.

NO.220 You have an urgent hotfix that needs to be deployed while a larger feature branch is still under review. Which strategies could you consider?

Merge the hotfix into the feature branch and wait for the entire feature to be approved.

Create a dedicated branch from the main branch specifically for the hotfix.

Temporarily revert the feature branch changes, deploy the hotfix, and then restore the feature branch.

Merge the hotfix into the main branch and then rebase the feature branch on top of the new main branch.

B: A dedicated hotfix branch isolates changes and provides the quickest path to deployment. D: Rebasing the feature branch after the hotfix ensures it includes the necessary fix.

NO.221 You’ve created a pull request, and a discussion in the code review reveals issues with the approach you used in your feature branch. Rather than continuously updating the original branch, what’s a strategy to address the feedback while keeping a clean pull request history?

Close the original pull request and create a new branch with the revised implementation.

Directly modify the commits on your existing feature branch using git rebase -i.

Add the changes as a new commit to your feature branch, explaining the revisions in the pull request comments.

Request that your collaborators edit the code directly within the pull request interface.

A: A new branch often provides the cleanest history for the reworked feature. B: Altering existing commits should be used judiciously, as it ‘rewrites’ history and can cause problems for collaborators.

NO.222 A model refactors a frequently used SQL calculation. Traditionally this logic was copied across multiple models. Which of the following is the LEAST likely benefit of refactoring this calculation into a macro?

Reduced error potential due to a single source of logic

Improved readability of models

Faster dbt job execution time

Simplified dependency tracking

While macros can sometimes marginally improve performance, their primary benefits are maintainability, readability, and clear dependency tracking.

NO.223 You need to parameterize a dbt model that filters data based on a country code. Which approach offers the BEST combination of flexibility and security?

Use environment variables in conjunction with Jinja to substitute the country code.

Build a dynamic query string entirely within a Jinja macro.

Pass the country code as a CLI argument when executing dbt run.

Create a seed file mapping country codes to filter values and reference it in the model.

Environment variables provide control and help prevent SQL injection risks. While the other options might work, they are less secure or less flexible.

NO.224 Given this dbt_project.yml:
name: “jaffle_shop”
version: “1.0.0”
config-version: 2
profile: “snowflake”
model-paths: [“models”]
macro-paths: [“macros”]
snapshot-paths: [“snapshots”]
target-path: “target”
clean-targets:
– “logs”
– “target”
– “dbt_modules”
– “dbt_packages”
models:
jaffle_shop:
orders:
materialized: table
When executing a dbt run your models build as views instead of tables:
19:36:14 Found 1 model, 0 tests, 0 snapshots, 0 analyses, 179 macros, 0 operations, 0 seed files, 0 sources, 0 exposures, 0 metrics
19:36:16 Concurrency: 1 threads (target=’default’)
19:36:17 Finished running 1 view model in 3.35s.
19:36:17 Completed successfully
19:36:17 Done. PASS=1 WARN=0 ERROR=0 SKIP=0 TOTAL=1
Which could be a root cause of why the model was not materialized as a table?
The target-path is incorrectly configured.

Yes

The behavior described-dbt running the orders model as a view despite being explicitly configured as a table
-indicates that dbt is not correctly detecting or applying the model-level configuration during compilation.
dbt relies heavily on the target-path directory to write compiled SQL, manifest files, and run artifacts. If the target-path is misconfigured, pointing to a location that dbt does not handle correctly or that overlaps with another folder used internally, dbt may fail to load the correct configuration from the merged project settings.
When dbt cannot locate the compiled configuration for a model, it defaults to its standard materialization type, which is view. This explains why the logs show:
“Finished running 1 view model”
even though the dbt_project.yml clearly declares:
materialized: table.
Additionally, the logs indicate no warnings or parsing errors, meaning dbt ran successfully but with incorrect settings-another indicator of configuration metadata being overridden or misplaced due to an incorrect target- path.
By resolving the target-path issue, dbt will successfully load the model configuration and materialize the orders model as a table as intended.

NO.225 Your team decides to use separate schemas for development and production within the same data warehouse. Which of the following dbt features are essential for managing this workflow effectively?

Macros and Jinja templating to dynamically switch target schemas.

dbt snapshots to compare data state between environments-

dbt seeds to populate test data in your development schema.

Environment variables to store environment-specific configurations.

A makes code portable across environments. D allows for environment-specific settings. B is useful, but not specific to multi-schema setups C is important for testing, but not the core deployment environment distinction.

NO.226 You’ve added new tests but notice they aren’t failing even though you’ve intentionally introduced errors. What’s a LIKELY cause?

You haven’t compiled your project since writing the new tests.

The tests are defined in seeds.csv files.

Your tests have incorrect severity thresholds.

Your dbt project has multiple targets configured.

Compilation is necessary for new tests to be recognized. Others are less likely, though severity thresholds could be a factor if misconfigured.

NO.227 You notice a pattern where warnings are generated for several models due to missing descriptions. How could you configure dbt_project.yml to fail these models instead when descriptions are absent?

Add on-run-start and on-run-end hooks to perform custom checks

Set a project-level severity setting under the tests: section.

Introduce a custom macro to validate model descriptions_

Globally change the default warning behavior using the warn-if: configuration

The warn-if: configuration lets you escalate specific warnings to errors at the project level.

NO.228 You’re refactoring a complex SQL query into a dbt model. You notice that the model’s output has significantly fewer rows than expected. Which of the following are potential causes?

Your model has accidental WHERE conditions that are too restrictive.

There may be a LIMIT statement leftover from development.

Upstream data has quality issues with null values or unexpected joins.

An incorrect materialization setting on the model.

All except D could limit the result set more than expected. Materialization settings impact how tables are built, not the SQL logic itself.

NO.229

Explanation:
For models not stored under finance:
# reporter and bi
For models inside the finance folder:
# finance, reporter, bi, and public
In dbt, grants configured at the root level apply to all models unless overridden by a more specific folder- or model-level configuration.
The root-level grant is:
+grants:
+select: [‘reporter’, ‘bi’]
This means all models by default are selectable by:
* reporter
* bi
Now the finance folder contains its own override:
finance:
+grants:
+select: [‘finance’]
When dbt merges grants, overrides do not replace the entire list-they add onto inherited grants unless explicitly cleared. Therefore, models inside the finance folder inherit the parent grants and add the finance grant.
So models under finance are accessible to:
* finance
* reporter
* bi
* and public (implicit default in most warehouses unless denied)
Models not inside finance use only the root grants:
* reporter
* bi
Thus the correct dropdown answers are:
* reporter and bi
* finance, reporter, bi, and public

NO.230 You need to test whether the values of a specific column have changed over time. What might be the best approach to implement this kind of test within your dbt project?

Use a snapshot to preserve a point-in-time reference of the column.

Use a custom ‘accepted_values’ test together with a dbt seed.

Write a dbt macro to create a temporary table with historical data to compare against.

rely on native version history features in your data warehouse (if available).

A provides a clean comparison point C enables more complex historical analysis. D leverages built-in warehouse features, if you have them.

NO.231 You’re tasked with adding functionality to your dbt project for:

Handling slowly changing dimensions.

Auditing data quality with comprehensive anomaly detection tests.

Calculating complex financial metrics specific to your industry

Data quality and SCD management are common needs addressed by many dbt packages. Financial metrics tend to be more domain-specific, and you might need custom logic.

NO.232 You discover that dbt models create objects with the default database user’s permissions. However, a policy mandates that analytics objects must be owned by a dedicated, less privileged account. How could you adapt your dbt workflow?

Implement pre-hooks or post-hooks to execute ALTER OWNER statements after model creation.

Configure the target database to automatically assign desired ownership to new objects in the schema

Modify your dbt profile to use the less privileged account’s credentials during job execution.

Write dbt macros that contain permission management logic as part of the model deployment.

A gives direct control within dbt C changes what dbt “does” by running as a different user- B might exist but be too broad, D overcomplicates models.

NO.233 You discover that a heavily used model is taking significantly longer to materialize. After investigation, you determine that the complexity of the model’s logic is a contributing factor. Which of the following actions is LEAST likely to help improve performance?

Break down the model into smaller, intermediate models using CTEs.

Change the materialization from a table to a view.

Investigate potential optimizations in the underlying SQL code.

Consider applying an incremental materialization strategy if suitable.

Switching from a table to a view alone doesn’t address the core performance issue of complex logic. Other options prioritize breaking down the transformations or directly optimizing the SQL itself.
