NEW QUESTION # 103
During development, you frequently used temporary print statements for debugging. Which of the following is the best practice before opening a pull request?
- A. Remove the print statements entirely from your commits-
- B. Leave the print statements for future reference, in case similar debugging is needed-
- C. Comment out the print statements but leave them in the code.
- D. Consolidate the print statements into a separate debugging function that can be toggled on and off
Answer: A
Explanation:
Debugging code should generally not be part of committed changes, as it clutters the codebase and offers no value to the core functionality.
NEW QUESTION # 104
You've made several commits to your feature branch. Before merging into the main branch, you want to consolidate the changes into a single, clear commit. What Git technique would help achieve this?
- A. Run git rebase main followed by git commit -amend.
- B. Use git rebase -i (interactive rebase) to squash commits together.
- C. Manually copy your files into a new branch, commit, and issue a pull request.
- D. git cherry-pick specific commits from your branch and reapply them.
Answer: B
Explanation:
Interactive rebasing (git rebase -i) provides fine-grained control to squash, edit, or rearrange commits, creating a cleaner commit history
NEW QUESTION # 105
Your dbt project contains both source descriptions (within your sources.yml file) and model descriptions. You notice that the source descriptions don't appear in the generated docs alongside the relevant models. What's then most likely reason?
- A. Source tables need to be explicitly tagged within your model configuration for their descriptions to appear
- B. A recent update to dbt has changed how source descriptions are integrated into the documentation.
- C. Your dbt_projectyml file is lacking the proper configuration to include source descriptions.
- D. Source descriptions only appear when you navigate directly to the Sources section of the documentation_
Answer: C
Explanation:
The dbt_project.yml file has settings that directly control the inclusion of source descriptions in the generated documentation. Its likely that you need to adjust these settings to display them correctly.
NEW QUESTION # 106
Your company is adopting a "data mesh" philosophy. How might this impact how you structure and use dbt projects?
- A. Increased focus on decentralized model ownership by domain-specific teams.
- B. No change in how dbt works, as it is a technology-agnostic tool.
- C. dbt's role becomes less important in a data mesh architecture.
- D. Stricter standardization of syntax and project structure is needed.
Answer: A
Explanation:
The distributed nature of a data mesh aligns well with having multiple, potentially smaller, dbt projects managed by teams closest to the data domains. The other options are inaccurate.
NEW QUESTION # 107
(Multiple Select)
- A. Changes in the structure or content of the baseline dataset itself.
- B. A change in database vendor for your data warehouse.
- C. Natural drift in the distribution of real-world data compared to the static baseline.
- D. Changes in business logic lead to intentional deviations from the baseline.
Answer: A,C,D
Explanation:
A, B, C all represent scenarios where the previous basis of comparison is no longer valid. D shouldn't affect tests, as dbt abstracts away database specifics.
NEW QUESTION # 108
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. Utilize dbt snapshots to capture a static set of API data for use during development and testing.
- B. Use environment variables to control API query frequency or switch between live and test data sources.
- 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.
NEW QUESTION # 109
You have a dbt macro that generates a list of models to execute dynamically. Which dbt command should you use in conjunction with this macro to actually run those models?
- A. dbt build to create a task graph, extracting model nodes, and running them as needed.
- B. dbt debug to step through model execution while using the macro's output
- C. dbt Is to retrieve project metadata and feed it into your custom execution logic.
- D. dbt parse to pre-compile the project graph, allowing model selection by reference.
Answer: D
Explanation:
A makes the dbt graph available, including macros, during execution- B gets metadata, but not for execution. C helps troubleshoot, but not run macros. D isn't designed for dynamic macro output
NEW QUESTION # 110
You need to run a custom Python script after your dbt models execute. Where and how can you configure this in your dbt_project.yml file?
- A. Utilize the on-run-end hook configuration.
- B. Include the script as a 'seed' file with a specific execution order
- C. Create an 'integration test' and use the PythonFunction class-
- D. Define it as a 'snapshot' to ensure it runs after all models.
Answer: A
Explanation:
on-run-end hooks allow you to execute arbitrary code at the end of a dbt run.
NEW QUESTION # 111
Type Mismatch
- A. Use a CAST operation within the affected model's SQL, leaving the underlying source unchanged.
- B. Handle the type conversion with a custom macro and apply it selectively within your dbt project.
- C. Introduce a staging model specifically to perform the type conversion, creating a clean separation.
- D. Modify the source table directly in the database to adjust the data type, ensuring backward compatibility.
Answer: C
Explanation:
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.
NEW QUESTION # 112
You want to use a YAML anchor to reuse a standard block of descriptive text within multiple models. How would you implement this?
- A. YAML anchors are not directly supported in the context of dbt model and source descriptions-
- B. Insert a YAML anchor (&) in your dbt_projectyml file and reference it in your model files.
- C. Define a Jinja macro for the text block, and then call the macro within your descriptions.
- D. Create a YAML anchor within the relevant model file where the text should be reused.
Answer: D
Explanation:
YAML anchors (&) and aliases (*) allow you to define reusable blocks of text within the same YAML file, such as model files or sources.yml.
NEW QUESTION # 113
You add a new seed file. Here's a snippet of your dbt_project.yml:YAML
- A. The syntax within the column_types section is incorrect
- B. The "+" is incorrect for nested elements in this context
- C. Specifying column_types directly under seeds is invalid in a dbt_project_yml.
- D. You cannot enable a seed file using the enabled property.
Answer: C
Explanation:
column_types config applies to individual seeds, not within the general seeds section. The others might be errors in different scenarios but less likely in this case-
NEW QUESTION # 114
You're setting up CI/CD for your dbt project to automate deployments. Which aspects of your testing strategy might need adaptation for a production-focused CI/CD workflow?
- A. Emphasizing tests with longer run times for thorough checks before deployment.
- B. Prioritizing tests with strict thresholds to avoid false positives from minor data variations in production.
- C. Disabling all tests that rely on creating new tables, to avoid impacting the production database.
- D. Including smoke tests that run in production to verify core functionality after a deployment.
Answer: B,D
Explanation:
B ensures the deployed changes actually work in the real environment. C helps maintain CI/CD flow without unnecessary disruptions. A is counterproductive in a time-sensitive CI/CD context. D would overly limit your testing coverage.
NEW QUESTION # 115
(Multiple Select)
- A. Upstream data sources update on a predictable cadence (e.g., daily extracts).
- B. You need to frequently load incremental data using dbt's snapshot feature.
- C. Your data warehouse has time-based pricing tiers, and you need models to refresh during off-peak hours.
- D. Downstream Bl dashboards rely on up-to-date data transformed by your dbt models-
Answer: A,D
Explanation:
B aligns model runs with data availability. C ensures Bl dashboards reflect the latest data. A is cost optimization, not a core freshness requirement. D snapshots are more about change tracking than regular updates.
NEW QUESTION # 116
You've updated a model's description in a YAML file to reflect a new business requirement. You've also added additional context to the column descriptions. After regenerating the documentation, you notice the model description has updated, but the column descriptions have not. What could be the most likely reasons?
- A. You are viewing an older cached version of the documentatiom
- B. The documentation was not configured correctly to display column descriptions.
- C. You forgot to run dbt docs generate after modifying the YAML file.
- D. The model's YAML file has incorrect syntax preventing column descriptions from rendering.
Answer: A,C
Explanation:
Explanation: B:
The dbt docs generate command is essential for updating the documentation website with changes made in the project files. D: Web browsers often cache content; you might need to clear your cache or force a refresh to see the latest changes.
NEW QUESTION # 117
(Multiple Select)
- A. Implement custom metrics tracking the duration and resource usage of individual dbt models.
- B. Integrating dbt's logging with your existing monitoring and alerting platforms.
- C. Using dbt Cloud's built-in job monitoring and notification features, if applicable.
- D. Require thorough code reviews with a focus on testability before deploying model changes to production.
Answer: A,B,C
Explanation:
These provide active monitoring of your dbt production environment. D is a good practice, but not about real-time observability
NEW QUESTION # 118
You've added new tests but notice they aren't failing even though you've intentionally introduced errors. What's a LIKELY cause?
- A. You haven't compiled your project since writing the new tests.
- B. Your dbt project has multiple targets configured.
- C. The tests are defined in seeds.csv files.
- D. Your tests have incorrect severity thresholds.
Answer: A
Explanation:
Compilation is necessary for new tests to be recognized. Others are less likely, though severity thresholds could be a factor if misconfigured.
NEW QUESTION # 119
(Multiple Select)
- A. Ensuring data synchronization after a migration.
- B. Validating changes during development before deploying a new dbt model version.
- C. Testing performance under a simulated heavy load.
- D. Catching subtle errors or discrepancies that may not cause immediate functional issues.
Answer: A,B,D
Explanation:
These tests help ensure alignment between the source of truth and the analytics environment. D (performance testing) is a different type of test.
NEW QUESTION # 120
A performance-critical model depends on multiple complex transformations that would benefit from being pre-computed. Direct querying of this model should be as fast as possible. Which materialization is likely the best choice?
- A. Incremental
- B. Ephemeral
- C. Table
- D. View
Answer: C
Explanation:
Explanation: Tables store materialized results on disk. When pre-calculated, they offer the fastest query response time, making them suitable for performance-sensitive models.
NEW QUESTION # 121
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?
- A. Snapshot
- B. Table
- C. Incremental
- D. View
Answer: A
Explanation:
Snapshots are designed for historical preservation. They capture the state of a source at a moment in time, providing a perfect audit trail.
NEW QUESTION # 122
You encounter the following error when running dbt compile:Runtime Error in model customer _ churn (models/transformations/customer_churn.sql)
- A. The fct_orders model depends on other models that haven't compiled successfully.
- B. There's a typo in how you're referencing the fct_orders object in your SQL.
- C. The fct_orders source is not configured correctly in your dbt_project.yml file.
- D. You need to add a schema test to validate the existence of the fct orders table.
Answer: B
Explanation:
Explanation: This is a runtime error indicating incorrect usage of fct_orders. Options A and C could cause errors but of a different nature. Schema tests won't fix a referencing error.
NEW QUESTION # 123
The dataset you work with contains personally identifiable information (PII). Which types of additional tooling might be necessary for your project beyond a core dbt implementation?
- A. Advanced statistical modeling tools.
- B. Automated ETL pipelines
- C. Data masking or tokenization solutions.
- D. Enhanced data access governance and auditing tools.
Answer: C,D
Explanation:
Data masking/tokenization protects sensitive data, and access governance/auditing ensures compliance when handling PII, which are distinct challenges from the core dbt workflow.
NEW QUESTION # 124
You're considering using dbt's --store-failures flag when running tests. Which of the following are potential implications of using this flag?
- A. Troublesl-ming failing tests will become easier, as data related to the failure is persisted.
- B. The overall dbt test command may run faster-
- C. Successful models will not be rebuilt if downstream dbt tests are marked as failures.
- D. This flag alters how dbt calculates test results
Answer: A
Explanation:
A is the primary purpose of -store-failures. B is not how dependencies work in dbt. C is unlikely as additional data storage is involved. D is not the case; it influences preservation of data associated with the test, not its logic.
