Microsoft DP-700 Practice Test 1

Question 1

A data engineering workspace hosts shared Spark workloads for several teams. An acceptance test shows that Spark sessions use an unexpected runtime after workspace migration. Which option directly handles this observed condition?

  1. Test the new runtime and pinned libraries in a nonproduction workspace before promotion
  2. Attach a versioned Fabric environment containing those libraries to the notebook
  3. Attach the intended default Lakehouse to the notebook before execution
  4. Set and verify the supported default Spark runtime for the workspace

Explanation

Correct Answer

D:

Set and verify the supported default Spark runtime for the workspace. Workspace defaults influence sessions that do not specify their own runtime.

Incorrect Answers

A:

A job fails after a Spark runtime upgrade changes package compatibility. Compatibility validation prevents a runtime change from silently breaking transformations.

B:

An analyst requires extra Python dependencies for a repeatable Spark job. An environment binds tested library versions to reproducible Spark execution.

C:

An engineer must run a notebook against a particular Lakehouse without hard-coded paths. Notebook lakehouse binding determines the default table and file context.

Question 2

A data engineering workspace hosts shared Spark workloads for several teams. The engineer has established the following constraint: an analyst requires extra Python dependencies for a repeatable Spark job. What is the most defensible next action?

  1. Attach a versioned Fabric environment containing those libraries to the notebook
  2. Separate the workload into suitable custom Spark pools and tune concurrency
  3. Attach the intended default Lakehouse to the notebook before execution
  4. Test the new runtime and pinned libraries in a nonproduction workspace before promotion

Explanation

Correct Answer

A:

Attach a versioned Fabric environment containing those libraries to the notebook. An environment binds tested library versions to reproducible Spark execution.

Incorrect Answers

B:

A large interactive notebook monopolizes resources needed by scheduled jobs. Pool configuration isolates resource behavior for distinct Spark workloads.

C:

An engineer must run a notebook against a particular Lakehouse without hard-coded paths. Notebook lakehouse binding determines the default table and file context.

D:

A job fails after a Spark runtime upgrade changes package compatibility. Compatibility validation prevents a runtime change from silently breaking transformations.

Question 3

A data engineering workspace hosts shared Spark workloads for several teams. During an operations handoff, engineers find that a large interactive notebook monopolizes resources needed by scheduled jobs. Which technical choice fits this evidence?

  1. Separate the workload into suitable custom Spark pools and tune concurrency
  2. Test the new runtime and pinned libraries in a nonproduction workspace before promotion
  3. Set and verify the supported default Spark runtime for the workspace
  4. Attach the intended default Lakehouse to the notebook before execution

Explanation

Correct Answer

A:

Separate the workload into suitable custom Spark pools and tune concurrency. Pool configuration isolates resource behavior for distinct Spark workloads.

Question 4

A data engineering workspace hosts shared Spark workloads for several teams. The team observes that an engineer must run a notebook against a particular Lakehouse without hard-coded paths. Which step preserves the intended data behavior?

  1. Set and verify the supported default Spark runtime for the workspace
  2. Attach a versioned Fabric environment containing those libraries to the notebook
  3. Attach the intended default Lakehouse to the notebook before execution
  4. Test the new runtime and pinned libraries in a nonproduction workspace before promotion

Explanation

Correct Answer

C:

Attach the intended default Lakehouse to the notebook before execution. Notebook lakehouse binding determines the default table and file context.

Incorrect Answers

A:

Spark sessions use an unexpected runtime after workspace migration. Workspace defaults influence sessions that do not specify their own runtime.

B:

An analyst requires extra Python dependencies for a repeatable Spark job. An environment binds tested library versions to reproducible Spark execution.

D:

A job fails after a Spark runtime upgrade changes package compatibility. Compatibility validation prevents a runtime change from silently breaking transformations.

Question 5

A data engineering workspace hosts shared Spark workloads for several teams. The implementation review confirms that a job fails after a Spark runtime upgrade changes package compatibility. Which change most directly resolves this failure?

  1. Set and verify the supported default Spark runtime for the workspace
  2. Separate the workload into suitable custom Spark pools and tune concurrency
  3. Attach the intended default Lakehouse to the notebook before execution
  4. Test the new runtime and pinned libraries in a nonproduction workspace before promotion

Explanation

Correct Answer

D:

Test the new runtime and pinned libraries in a nonproduction workspace before promotion. Compatibility validation prevents a runtime change from silently breaking transformations.

Incorrect Answers

A:

Spark sessions use an unexpected runtime after workspace migration. Workspace defaults influence sessions that do not specify their own runtime.

B:

A large interactive notebook monopolizes resources needed by scheduled jobs. Pool configuration isolates resource behavior for distinct Spark workloads.

C:

An engineer must run a notebook against a particular Lakehouse without hard-coded paths. Notebook lakehouse binding determines the default table and file context.

Question 6

A Fabric workspace runs long and short Spark sessions under a shared capacity. A scheduled execution exposes this issue: Spark startup latency is high when every notebook provisions new executors. Which approach best satisfies this requirement?

  1. Adjust Spark executor memory and partitioning for the measured stage
  2. Review Spark pool capacity and admission/concurrency controls for the workspace
  3. Inspect notebook-specific settings and environment overrides against workspace defaults
  4. Evaluate a suitable starter pool and configured session reuse where supported

Explanation

Correct Answer

D:

Evaluate a suitable starter pool and configured session reuse where supported. Appropriate pool/session settings can reduce repeated startup overhead.

Incorrect Answers

A:

A large shuffle job repeatedly exhausts its executors. Insufficient executor resources or skew can fail shuffles despite available capacity.

B:

Two concurrent jobs interfere despite different business priorities. Concurrency tuning must account for the capacity consumed by simultaneous runs.

C:

Session settings changed in the UI but a job retains old values. Item-level or environment configuration can supersede the workspace's defaults.

Question 7

A Fabric workspace runs long and short Spark sessions under a shared capacity. Data validation establishes that a large shuffle job repeatedly exhausts its executors. Which corrective action addresses the root cause?

  1. Review Spark pool capacity and admission/concurrency controls for the workspace
  2. Inspect notebook-specific settings and environment overrides against workspace defaults
  3. Adjust Spark executor memory and partitioning for the measured stage
  4. Evaluate a suitable starter pool and configured session reuse where supported

Explanation

Correct Answer

C:

Adjust Spark executor memory and partitioning for the measured stage. Insufficient executor resources or skew can fail shuffles despite available capacity.

Incorrect Answers

A:

Two concurrent jobs interfere despite different business priorities. Concurrency tuning must account for the capacity consumed by simultaneous runs.

B:

Session settings changed in the UI but a job retains old values. Item-level or environment configuration can supersede the workspace's defaults.

D:

Spark startup latency is high when every notebook provisions new executors. Appropriate pool/session settings can reduce repeated startup overhead.

Question 8

A Fabric workspace runs long and short Spark sessions under a shared capacity. The production incident report states that idle interactive sessions retain resources unnecessarily. What should the administrator implement or verify?

  1. Adjust Spark executor memory and partitioning for the measured stage
  2. Review Spark pool capacity and admission/concurrency controls for the workspace
  3. Inspect notebook-specific settings and environment overrides against workspace defaults
  4. Configure supported idle timeout and automatic session termination settings

Explanation

Correct Answer

D:

Configure supported idle timeout and automatic session termination settings. Stopping idle sessions releases shared Spark capacity for new work.
