Question 410

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

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

  1. A new job run appears for the intended deployed resource and target environment.
  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. Production contains the required schedule and DAG after deployment, not just the notebook source.

Explanation

Correct Answer

B:

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

Incorrect Answers

A:

A new job run appears for the intended deployed resource and target environment. That finding does not establish that the configured job resource appears in the target workspace after successful deployment.

C:

Validation resolves the common project identity for both development and production targets. That finding does not establish that the configured job resource appears in the target workspace after successful deployment.

D:

Production contains the required schedule and DAG after deployment, not just the notebook source. That finding does not establish that the configured job resource appears in the target workspace after successful deployment.

Question 411

After deploying a bundle, an engineer needs to start its defined Lakeflow Job from the CLI without searching for a generated UI link.

Which implementation decision best addresses this requirement?

  1. Run databricks bundle run with the target and declared job resource identifier.
  2. Include source files, databricks.yml metadata, and the resource and target definitions in the bundle project.
  3. Use a properly scoped service principal or supported non-personal deployment identity in CI.
  4. Explicitly specify the production target when validating and deploying the bundle.

Explanation

Correct Answer

A:

The bundle CLI can execute a deployed resource by its logical bundle configuration name. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

B:

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

C:

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

D:

When a default target exists, commands without a target can operate on development; explicit targeting reduces misdeployment.

Question 412

After deploying a bundle, an engineer needs to start its defined Lakeflow Job from the CLI without searching for a generated UI link.

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

  1. The bundle validates and deploys both its source logic and job resources from the project folder.
  2. The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.
  3. A new job run appears for the intended deployed resource and target environment.
  4. The deploy log identifies production and the development workspace remains unchanged.

Explanation

Correct Answer

C:

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

Incorrect Answers

A:

The bundle validates and deploys both its source logic and job resources from the project folder. That finding does not establish that a new job run appears for the intended deployed resource and target environment.

B:

The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access. That finding does not establish that a new job run appears for the intended deployed resource and target environment.

D:

The deploy log identifies production and the development workspace remains unchanged. That finding does not establish that a new job run appears for the intended deployed resource and target environment.

Question 413

A project stores Python source files and a job declaration, but an engineer incorrectly believes a bundle is just a ZIP of notebooks.

Which implementation decision best addresses this requirement?

  1. Include source files, databricks.yml metadata, and the resource and target definitions in the bundle project.
  2. Declare the appropriate bundle metadata and resources in the main Databricks bundle configuration.
  3. Run the bundle validation command as a required earlier CI step.
  4. Use consistent bundle resource identities and normal bundle deployment lifecycle for updates.

Explanation

Correct Answer

A:

Bundles describe a complete deployable project, including resources and environment settings—not only code archives. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

B:

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

C:

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

D:

Resource management through a bundle can update its declared resource rather than treating each deployment as an unrelated manual copy.

Question 414

A project stores Python source files and a job declaration, but an engineer incorrectly believes a bundle is just a ZIP of notebooks.

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

  1. Validation resolves the common project identity for both development and production targets.
  2. A deliberately invalid bundle stops the workflow before the deploy stage.
  3. The second deployment updates the same intended logical job with no unexpected duplicate production job.
  4. The bundle validates and deploys both its source logic and job resources from the project folder.

Explanation

Correct Answer

D:

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

Incorrect Answers

A:

Validation resolves the common project identity for both development and production targets. That finding does not establish that the bundle validates and deploys both its source logic and job resources from the project folder.

B:

A deliberately invalid bundle stops the workflow before the deploy stage. That finding does not establish that the bundle validates and deploys both its source logic and job resources from the project folder.

C:

The second deployment updates the same intended logical job with no unexpected duplicate production job. That finding does not establish that the bundle validates and deploys both its source logic and job resources from the project folder.

Question 415

A team wants a reusable project name and centrally defined common settings across several deployment environments.

Which implementation decision best addresses this requirement?

  1. Use a properly scoped service principal or supported non-personal deployment identity in CI.
  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. Review the repository diff and require merge approval for production release branches.

Explanation

Correct Answer

B:

A top-level bundle definition anchors common configuration and reduces environment-specific duplication. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

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

C:

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

D:

Version control and pull-request review make code changes auditable before automated deployment.

Question 416

A team wants a reusable project name and centrally defined common settings across several deployment environments.

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

  1. The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.
  2. Production contains the required schedule and DAG after deployment, not just the notebook source.
  3. The promoted commit is the reviewed commit and unauthorized changes cannot bypass the protected branch.
  4. Validation resolves the common project identity for both development and production targets.

Explanation

Correct Answer

D:

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

Incorrect Answers

A:

The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access. That finding does not establish that validation resolves the common project identity for both development and production targets.

B:

Production contains the required schedule and DAG after deployment, not just the notebook source. That finding does not establish that validation resolves the common project identity for both development and production targets.

C:

The promoted commit is the reviewed commit and unauthorized changes cannot bypass the protected branch. That finding does not establish that validation resolves the common project identity for both development and production targets.

Question 417

A production pipeline must not use a developer's personal credentials when triggered through CI/CD.

Which implementation decision best addresses this requirement?

  1. Run the bundle validation command as a required earlier CI step.
  2. Explicitly specify the production target when validating and deploying the bundle.
  3. Use a properly scoped service principal or supported non-personal deployment identity in CI.
  4. Use environment-specific workspace paths or target overrides that isolate bundle-managed resources.

Explanation

Correct Answer

C:

Non-personal identity avoids tying production deployments to an engineer's account and supports least privilege. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

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

B:

When a default target exists, commands without a target can operate on development; explicit targeting reduces misdeployment.

D:

Deployment paths must not collide across targets or with independently owned workspace assets.

Question 418

A production pipeline must not use a developer's personal credentials when triggered through CI/CD.

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

  1. The CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.
  2. A deliberately invalid bundle stops the workflow before the deploy stage.
  3. The deploy log identifies production and the development workspace remains unchanged.
  4. The production bundle operates only in its assigned workspace namespace and leaves unrelated assets unchanged.

Explanation

Correct Answer

A:

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

Incorrect Answers

B:

A deliberately invalid bundle stops the workflow before the deploy stage. That finding does not establish that the CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.

C:

The deploy log identifies production and the development workspace remains unchanged. That finding does not establish that the CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.

D:

The production bundle operates only in its assigned workspace namespace and leaves unrelated assets unchanged. That finding does not establish that the CI pipeline deploys under a dedicated identity and still works after the original developer loses workspace access.

Question 419

A team wants its CI system to reject malformed bundle configuration before deploying any production job.

Which implementation decision best addresses this requirement?

  1. Package the notebook and its Lakeflow Job resource definition in a Declarative Automation Bundle.
  2. Use consistent bundle resource identities and normal bundle deployment lifecycle for updates.
  3. Run the bundle validation command as a required earlier CI step.
  4. Parameterize catalog identifiers and supply target-specific values during deployment.

Explanation

Correct Answer

C:

Validation in CI catches structural defects before resource mutation and reduces broken deployments. The selected implementation is the one directly aligned with the constraints in the scenario.

Incorrect Answers

A:

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

B:

Resource management through a bundle can update its declared resource rather than treating each deployment as an unrelated manual copy.

D:

Question 420

A team wants its CI system to reject malformed bundle configuration before deploying any production job.

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

  1. Production contains the required schedule and DAG after deployment, not just the notebook source.
  2. A deliberately invalid bundle stops the workflow before the deploy stage.
  3. The second deployment updates the same intended logical job with no unexpected duplicate production job.
