Question 920

A platform automation service manages resources in several Databricks workspaces. After configuring Move authentication to managed profiles and sanitize request/response logging, the engineer must validate: A script logs access tokens during API debugging. What evidence is decisive?

  1. The response returns a new job run ID that can be monitored
  2. The collected job count matches the complete paginated inventory
  3. No token appears in logs and authenticated requests still succeed
  4. Run details include task states and failure messages

Explanation

Correct Answer

C:

No token appears in logs and authenticated requests still succeed directly measures whether Move authentication to managed profiles and sanitize request/response logging achieved the requirement “A script logs access tokens during API debugging.” It checks the operating result rather than just a configured resource name.

Incorrect Answers

A:

This signal belongs to the adjacent case “A script needs to start an existing job and collect its run ID,” whose remedy is Call the supported Jobs run-now API or CLI command. The observed result for the present requirement is No token appears in logs and authenticated requests still succeed.

B:

The collected job count matches the complete paginated inventory would demonstrate the separate action Follow pagination tokens until all results have been retrieved, which addresses “A script lists many jobs and silently misses results beyond one API page.” It does not verify the requirement “A script logs access tokens during API debugging” following Move authentication to managed profiles and sanitize request/response logging.

D:

Run details include task states and failure messages would demonstrate the separate action Use supported Jobs get-run API or CLI command, which addresses “An operator needs to inspect details of a failed run automatically.” It does not verify the requirement “A script logs access tokens during API debugging” following Move authentication to managed profiles and sanitize request/response logging.

Question 921

A data engineering release includes custom wheels and third-party Python libraries. Production acceptance depends on this condition: A wheel was built for a different Python version than the job runtime. What should the engineer configure?

  1. Refactor import-time code into explicitly called initialization
  2. Build a compatible distribution or update runtime within supported constraints
  3. Select supported compatible compute or replace the incompatible dependency
  4. Declare it as a task or bundle environment dependency

Explanation

Correct Answer

B:

The requested outcome is “A wheel was built for a different Python version than the job runtime.” Build a compatible distribution or update runtime within supported constraints is the matching action; A fresh job imports the wheel without ABI errors gives observable acceptance evidence.

Incorrect Answers

A:

Refactor import-time code into explicitly called initialization belongs to the separate case “A package import creates unexpected side effects each time a worker loads it,” where Repeated worker imports no longer trigger unintended data writes would be expected. That differs from the condition in this stem: “A wheel was built for a different Python version than the job runtime.”

C:

Select supported compatible compute or replace the incompatible dependency is appropriate when “A task fails only on serverless compute because an unsupported native extension is required”; it would be verified by The task runs successfully in its documented supported environment. It does not directly satisfy “A wheel was built for a different Python version than the job runtime,” whose relevant acceptance evidence is A fresh job imports the wheel without ABI errors.

D:

Declare it as a task or bundle environment dependency belongs to the separate case “An external library is available to the notebook author but not to scheduled tasks,” where Scheduled job task loads the required module successfully would be expected. That differs from the condition in this stem: “A wheel was built for a different Python version than the job runtime.”

Question 922

A data engineering release includes custom wheels and third-party Python libraries. The team implements Build a compatible distribution or update runtime within supported constraints. The goal was: A wheel was built for a different Python version than the job runtime. Which observed result best verifies success?

  1. The task runs successfully in its documented supported environment
  2. The known-good test case passes under the pinned versions
  3. A fresh job imports the wheel without ABI errors
  4. Repeated worker imports no longer trigger unintended data writes

Explanation

Correct Answer

C:

The acceptance criterion for “A wheel was built for a different Python version than the job runtime” is A fresh job imports the wheel without ABI errors; this is the expected evidence after Build a compatible distribution or update runtime within supported constraints.

Incorrect Answers

A:

This signal belongs to the adjacent case “A task fails only on serverless compute because an unsupported native extension is required,” whose remedy is Select supported compatible compute or replace the incompatible dependency. The observed result for the present requirement is A fresh job imports the wheel without ABI errors.

B:

This signal belongs to the adjacent case “A transitive dependency upgrade breaks a stable transformation,” whose remedy is Lock a compatible dependency graph and test before redeploying. The observed result for the present requirement is A fresh job imports the wheel without ABI errors.

D:

That observation is a valid indicator for “A package import creates unexpected side effects each time a worker loads it” when using Refactor import-time code into explicitly called initialization. The scenario instead tests “A wheel was built for a different Python version than the job runtime”; the relevant result is A fresh job imports the wheel without ABI errors.

Question 923

A data engineering release includes custom wheels and third-party Python libraries. An incident review prioritizes one requirement: An external library is available to the notebook author but not to scheduled tasks. What is the most defensible remedy?

  1. Lock a compatible dependency graph and test before redeploying
  2. Build a compatible distribution or update runtime within supported constraints
  3. Declare it as a task or bundle environment dependency
  4. Refactor import-time code into explicitly called initialization

Explanation

Correct Answer

C:

Declare it as a task or bundle environment dependency addresses the requested condition (“An external library is available to the notebook author but not to scheduled tasks”) rather than an adjacent platform task. The independent success check is: Scheduled job task loads the required module successfully.

Incorrect Answers

A:

The alternative Lock a compatible dependency graph and test before redeploying has a distinct purpose—A transitive dependency upgrade breaks a stable transformation. It would not establish the required outcome (An external library is available to the notebook author but not to scheduled tasks); the necessary verification concerns Scheduled job task loads the required module successfully.

B:

Build a compatible distribution or update runtime within supported constraints is appropriate when “A wheel was built for a different Python version than the job runtime”; it would be verified by A fresh job imports the wheel without ABI errors. It does not directly satisfy “An external library is available to the notebook author but not to scheduled tasks,” whose relevant acceptance evidence is Scheduled job task loads the required module successfully.

That differs from the condition in this stem: “An external library is available to the notebook author but not to scheduled tasks.”

Question 924

A data engineering release includes custom wheels and third-party Python libraries. The change record shows Declare it as a task or bundle environment dependency. The acceptance test concerns: An external library is available to the notebook author but not to scheduled tasks. Which outcome confirms it?

  1. A fresh job imports the wheel without ABI errors
  2. The known-good test case passes under the pinned versions
  3. The task runs successfully in its documented supported environment
  4. Scheduled job task loads the required module successfully

Explanation

Correct Answer

D:

Scheduled job task loads the required module successfully is the matching outcome for the implemented control (Declare it as a task or bundle environment dependency) and the stated requirement “An external library is available to the notebook author but not to scheduled tasks.”

Incorrect Answers

A:

A fresh job imports the wheel without ABI errors would demonstrate the separate action Build a compatible distribution or update runtime within supported constraints, which addresses “A wheel was built for a different Python version than the job runtime.” It does not verify the requirement “An external library is available to the notebook author but not to scheduled tasks” following Declare it as a task or bundle environment dependency.

B:

The known-good test case passes under the pinned versions would demonstrate the separate action Lock a compatible dependency graph and test before redeploying, which addresses “A transitive dependency upgrade breaks a stable transformation.” It does not verify the requirement “An external library is available to the notebook author but not to scheduled tasks” following Declare it as a task or bundle environment dependency.

C:

The scenario instead tests “An external library is available to the notebook author but not to scheduled tasks”; the relevant result is Scheduled job task loads the required module successfully.

Question 925

A data engineering release includes custom wheels and third-party Python libraries. A scheduled release needs to solve this problem: A transitive dependency upgrade breaks a stable transformation. What should the team implement?

  1. Declare it as a task or bundle environment dependency
  2. Lock a compatible dependency graph and test before redeploying
  3. Select supported compatible compute or replace the incompatible dependency
  4. Refactor import-time code into explicitly called initialization

Explanation

Correct Answer

B:

Lock a compatible dependency graph and test before redeploying addresses the requested condition (“A transitive dependency upgrade breaks a stable transformation”) rather than an adjacent platform task. The independent success check is: The known-good test case passes under the pinned versions.

Incorrect Answers

A:

This action solves a different issue: “An external library is available to the notebook author but not to scheduled tasks.” Its normal signal is Scheduled job task loads the required module successfully. Here the requested behavior is “A transitive dependency upgrade breaks a stable transformation,” so that signal is not sufficient.

C:

Select supported compatible compute or replace the incompatible dependency belongs to the separate case “A task fails only on serverless compute because an unsupported native extension is required,” where The task runs successfully in its documented supported environment would be expected. That differs from the condition in this stem: “A transitive dependency upgrade breaks a stable transformation.”

D:

Explanation

Correct Answer

C:

The known-good test case passes under the pinned versions directly measures whether Lock a compatible dependency graph and test before redeploying achieved the requirement “A transitive dependency upgrade breaks a stable transformation.” It checks the operating result rather than just a configured resource name.

A:

This signal belongs to the adjacent case “A wheel was built for a different Python version than the job runtime,” whose remedy is Build a compatible distribution or update runtime within supported constraints.

D:

Repeated worker imports no longer trigger unintended data writes pertains to a different control (Refactor import-time code into explicitly called initialization) and a different need (A package import creates unexpected side effects each time a worker loads it). It cannot establish that Lock a compatible dependency graph and test before redeploying met the stated goal.

Question 929

A data engineering release includes custom wheels and third-party Python libraries. The current design is incomplete because: A task fails only on serverless compute because an unsupported native extension is required. Which change addresses it directly?

  1. Refactor import-time code into explicitly called initialization
  2. Lock a compatible dependency graph and test before redeploying
  3. Build a compatible distribution or update runtime within supported constraints
  4. Select supported compatible compute or replace the incompatible dependency

Explanation

Correct Answer

D:

The requirement concerns “A task fails only on serverless compute because an unsupported native extension is required.” The selected operation, Select supported compatible compute or replace the incompatible dependency, is the direct engineering control. Its effect can be checked by confirming: The task runs successfully in its documented supported environment.

Incorrect Answers

A:

Refactor import-time code into explicitly called initialization is appropriate when “A package import creates unexpected side effects each time a worker loads it”; it would be verified by Repeated worker imports no longer trigger unintended data writes. It does not directly satisfy “A task fails only on serverless compute because an unsupported native extension is required,” whose relevant acceptance evidence is The task runs successfully in its documented supported environment.

Question 930

A data engineering release includes custom wheels and third-party Python libraries. An auditor must prove the outcome of Select supported compatible compute or replace the incompatible dependency for this requirement: A task fails only on serverless compute because an unsupported native extension is required. Which test result is best?

  1. The task runs successfully in its documented supported environment
  2. Repeated worker imports no longer trigger unintended data writes
  3. A fresh job imports the wheel without ABI errors
  4. Scheduled job task loads the required module successfully

Explanation
