Question 400

A team wants to test an experimental ETL change without modifying the shared main branch used by production.

Which acceptance result most directly demonstrates that the intended solution works?

  1. The deployed notebook commit matches the approved remote main-branch revision.
  2. Staging writes to staging resources while production writes to its independently governed targets.
  3. The main branch retains its original notebook content until the reviewed change is merged.
  4. A new job run appears for the intended deployed resource and target environment.

Explanation

Correct Answer

C:

Feature branches isolate work-in-progress revisions from the main release line.

Incorrect Answers

A:

The deployed notebook commit matches the approved remote main-branch revision. That finding does not establish that the main branch retains its original notebook content until the reviewed change is merged.

B:

Staging writes to staging resources while production writes to its independently governed targets. That finding does not establish that the main branch retains its original notebook content until the reviewed change is merged.

D:

A new job run appears for the intended deployed resource and target environment. That finding does not establish that the main branch retains its original notebook content until the reviewed change is merged.

Question 401

After a pull request is merged, a long-lived Databricks Git folder still shows older notebook code and deployment uses the stale version.

Which implementation decision best addresses this requirement?

  1. Synchronize or pull the latest intended branch commit before packaging and deploying.
  2. Define explicit targets and workspace host overrides for the environments in the bundle configuration.
  3. Run databricks bundle validate for the relevant target.
  4. Include source files, databricks.yml metadata, and the resource and target definitions in the bundle project.

Explanation

Correct Answer

A:

A workspace Git folder must reflect the remote revision intended for release. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

B:

Target-specific configuration allows the same codebase to deploy to different workspaces safely.

C:

Bundle validation checks configuration resolution and catches many definition issues before deployment.

D:

Bundles describe a complete deployable project, including resources and environment settings—not only code archives.

Question 402

After a pull request is merged, a long-lived Databricks Git folder still shows older notebook code and deployment uses the stale version.

Which acceptance result most directly demonstrates that the intended solution works?

  1. The production target deploys to its approved host and does not modify development assets.
  2. An invalid resource reference causes validation to report an error without creating the target job.
  3. The bundle validates and deploys both its source logic and job resources from the project folder.
  4. The deployed notebook commit matches the approved remote main-branch revision.

Explanation

Correct Answer

D:

A workspace Git folder must reflect the remote revision intended for release.

Incorrect Answers

A:

The production target deploys to its approved host and does not modify development assets. That finding does not establish that the deployed notebook commit matches the approved remote main-branch revision.

B:

An invalid resource reference causes validation to report an error without creating the target job. That finding does not establish that the deployed notebook commit matches the approved remote main-branch revision.

C:

The bundle validates and deploys both its source logic and job resources from the project folder. That finding does not establish that the deployed notebook commit matches the approved remote main-branch revision.

Question 403

A Declarative Automation Bundle deploys correctly to development but fails in production because the production workspace URL was hardcoded to the development host.

Which implementation decision best addresses this requirement?

  1. Use bundle variables and target-specific overrides for environment-dependent values.
  2. Define explicit targets and workspace host overrides for the environments in the bundle configuration.
  3. Execute databricks bundle deploy for the intended target after validation.
  4. Declare the appropriate bundle metadata and resources in the main Databricks bundle configuration.

Explanation

Correct Answer

B:

Target-specific configuration allows the same codebase to deploy to different workspaces safely. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

Environment variables keep source code common while allowing controlled resource and configuration differences.

C:

Validation and deployment are different operations; deploy creates or updates configured Databricks resources.

D:

A top-level bundle definition anchors common configuration and reduces environment-specific duplication.

Question 404

A Declarative Automation Bundle deploys correctly to development but fails in production because the production workspace URL was hardcoded to the development host.

Which acceptance result most directly demonstrates that the intended solution works?

  1. Staging writes to staging resources while production writes to its independently governed targets.
  2. The configured job resource appears in the target workspace after successful deployment.
  3. Validation resolves the common project identity for both development and production targets.
  4. The production target deploys to its approved host and does not modify development assets.

Explanation

Correct Answer

D:

Target-specific configuration allows the same codebase to deploy to different workspaces safely.

Incorrect Answers

A:

Staging writes to staging resources while production writes to its independently governed targets. That finding does not establish that the production target deploys to its approved host and does not modify development assets.

B:

The configured job resource appears in the target workspace after successful deployment. That finding does not establish that the production target deploys to its approved host and does not modify development assets.

C:

Validation resolves the common project identity for both development and production targets. That finding does not establish that the production target deploys to its approved host and does not modify development assets.

Question 405

A team wants identical transformation logic in test and production but different catalog names, service identities and warehouse references.

Which implementation decision best addresses this requirement?

  1. Run databricks bundle validate for the relevant target.
  2. Run databricks bundle run with the target and declared job resource identifier.
  3. Use bundle variables and target-specific overrides for environment-dependent values.
  4. Use a properly scoped service principal or supported non-personal deployment identity in CI.

Explanation

Correct Answer

C:

Environment variables keep source code common while allowing controlled resource and configuration differences. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

Bundle validation checks configuration resolution and catches many definition issues before deployment.

B:

The bundle CLI can execute a deployed resource by its logical bundle configuration name.

D:

Non-personal identity avoids tying production deployments to an engineer's account and supports least privilege.

Question 406

A team wants identical transformation logic in test and production but different catalog names, service identities and warehouse references.

Which acceptance result most directly demonstrates that the intended solution works?

  1. Staging writes to staging resources while production writes to its independently governed targets.
  2. An invalid resource reference causes validation to report an error without creating the target job.
  3. A new job run appears for the intended deployed resource and target environment.
  4. The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.

Explanation

Correct Answer

A:

Environment variables keep source code common while allowing controlled resource and configuration differences.

Incorrect Answers

B:

An invalid resource reference causes validation to report an error without creating the target job. That finding does not establish that staging writes to staging resources while production writes to its independently governed targets.

C:

A new job run appears for the intended deployed resource and target environment. That finding does not establish that staging writes to staging resources while production writes to its independently governed targets.

D:

The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access. That finding does not establish that staging writes to staging resources while production writes to its independently governed targets.

Question 407

A developer needs to validate a Databricks bundle configuration before making any changes to workspace resources.

Which implementation decision best addresses this requirement?

  1. Execute databricks bundle deploy for the intended target after validation.
  2. Include source files, databricks.yml metadata, and the resource and target definitions in the bundle project.
  3. Run databricks bundle validate for the relevant target.
  4. Run the bundle validation command as a required earlier CI step.

Explanation

Correct Answer

C:

Bundle validation checks configuration resolution and catches many definition issues before deployment. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

Validation and deployment are different operations; deploy creates or updates configured Databricks resources.

B:

Bundles describe a complete deployable project, including resources and environment settings—not only code archives.

D:

Validation in CI catches structural defects before resource mutation and reduces broken deployments.

Question 408

A developer needs to validate a Databricks bundle configuration before making any changes to workspace resources.

Which acceptance result most directly demonstrates that the intended solution works?

  1. The configured job resource appears in the target workspace after successful deployment.
  2. An invalid resource reference causes validation to report an error without creating the target job.
  3. The bundle validates and deploys both its source logic and job resources from the project folder.
  4. A deliberately invalid bundle stops the workflow before the deploy stage.

Explanation

Correct Answer

B:

Bundle validation checks configuration resolution and catches many definition issues before deployment.

Incorrect Answers

A:

The configured job resource appears in the target workspace after successful deployment. That finding does not establish that an invalid resource reference causes validation to report an error without creating the target job.

C:

The bundle validates and deploys both its source logic and job resources from the project folder. That finding does not establish that an invalid resource reference causes validation to report an error without creating the target job.

D:

A deliberately invalid bundle stops the workflow before the deploy stage. That finding does not establish that an invalid resource reference causes validation to report an error without creating the target job.

Question 409

A team has validated a bundle but assumes that alone will create its jobs in the workspace.

Which implementation decision best addresses this requirement?

  1. Run databricks bundle run with the target and declared job resource identifier.
  2. Declare the appropriate bundle metadata and resources in the main Databricks bundle configuration.
  3. Package the notebook and its Lakeflow Job resource definition in a Declarative Automation Bundle.
  4. Execute databricks bundle deploy for the intended target after validation.

Explanation

Correct Answer

D:

Validation and deployment are different operations; deploy creates or updates configured Databricks resources. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

The bundle CLI can execute a deployed resource by its logical bundle configuration name.

B:

A top-level bundle definition anchors common configuration and reduces environment-specific duplication.

C:

Resource-as-code deployment promotes job behavior along with executable logic.

Question 410
