Question 540

A team monitors Fabric pipeline Copy activity performance. The current environment exhibits the following problem: failures recur but support cannot identify the exact source credential. What is the most defensible next action?

  1. Retain run IDs, connection identity and sanitized error context
  2. Compare source-read and sink-written row metrics for the activity
  3. Inspect activity duration, source throughput and partition skew
  4. Verify trigger schedule, parameters and actual invocation logs

Explanation

Correct Answer

A:

Retain run IDs, connection identity and sanitized error context. Reproducible diagnostics require the failing execution's context.

Incorrect Answers

B:

A copy moved fewer rows than the source extract should contain. Copy metrics expose differences between extraction and persistence.

C:

A copy is slow only for one large partition. A single hot partition can dominate total copy elapsed time.

D:

A scheduled pipeline doesn't appear in the expected run history. Missing runs are different from failed activities.

Question 541

A Spark team profiles notebook execution inside a production Fabric workspace. An acceptance test shows that a notebook cell completes slowly with heavy shuffle writes. Which technical choice fits this evidence?

  1. Trace the calling pipeline or job definition run and its notebook activity
  2. Review executor logs and memory metrics from the Spark application
  3. Monitor processed row counts or output freshness, not just application liveness
  4. Inspect Spark UI jobs/stages for shuffle and task skew

Explanation

Correct Answer

D:

Inspect Spark UI jobs/stages for shuffle and task skew. Stage metrics identify expensive redistribution work.

Incorrect Answers

A:

A notebook executes interactively but no scheduled run appears. Interactive and orchestrated Spark executions have different entry points.

B:

Executors terminate with memory errors during a wide transformation. Memory failures are diagnosed through the specific task and executor evidence.

C:

A running notebook shows normal status while output stopped changing. Execution progress and business-data progress are separate measurements.

Question 542

A Spark team profiles notebook execution inside a production Fabric workspace. The engineer has established the following constraint: executors terminate with memory errors during a wide transformation. Which step preserves the intended data behavior?

  1. Inspect Spark UI jobs/stages for shuffle and task skew
  2. Review executor logs and memory metrics from the Spark application
  3. Record the notebook parameters, run ID and target output path
  4. Trace the calling pipeline or job definition run and its notebook activity

Explanation

Correct Answer

B:

Review executor logs and memory metrics from the Spark application. Memory failures are diagnosed through the specific task and executor evidence.

Incorrect Answers

A:

A notebook cell completes slowly with heavy shuffle writes. Stage metrics identify expensive redistribution work.

C:

Operations needs to correlate a Spark job to the data partition it wrote. Run-level lineage connects a transformation with its published data.

D:

A notebook executes interactively but no scheduled run appears. Interactive and orchestrated Spark executions have different entry points.

Question 543

A Spark team profiles notebook execution inside a production Fabric workspace. During an operations handoff, engineers find that a notebook executes interactively but no scheduled run appears. Which change most directly resolves this failure?

  1. Inspect Spark UI jobs/stages for shuffle and task skew
  2. Monitor processed row counts or output freshness, not just application liveness
  3. Review executor logs and memory metrics from the Spark application
  4. Trace the calling pipeline or job definition run and its notebook activity

Explanation

Correct Answer

D:

Trace the calling pipeline or job definition run and its notebook activity. Interactive and orchestrated Spark executions have different entry points.

Incorrect Answers

A:

A notebook cell completes slowly with heavy shuffle writes. Stage metrics identify expensive redistribution work.

B:

A running notebook shows normal status while output stopped changing. Execution progress and business-data progress are separate measurements.

C:

Executors terminate with memory errors during a wide transformation. Memory failures are diagnosed through the specific task and executor evidence.

Question 544

A Spark team profiles notebook execution inside a production Fabric workspace. The team observes that operations needs to correlate a Spark job to the data partition it wrote. What is the best engineering response?

  1. Record the notebook parameters, run ID and target output path
  2. Review executor logs and memory metrics from the Spark application
  3. Inspect Spark UI jobs/stages for shuffle and task skew
  4. Monitor processed row counts or output freshness, not just application liveness

Explanation

Correct Answer

A:

Record the notebook parameters, run ID and target output path. Run-level lineage connects a transformation with its published data.

Incorrect Answers

B:

Executors terminate with memory errors during a wide transformation. Memory failures are diagnosed through the specific task and executor evidence.

C:

A notebook cell completes slowly with heavy shuffle writes. Stage metrics identify expensive redistribution work.

D:

A running notebook shows normal status while output stopped changing. Execution progress and business-data progress are separate measurements.

Question 545

A Spark team profiles notebook execution inside a production Fabric workspace. The implementation review confirms that a running notebook shows normal status while output stopped changing. Which action should the team take next?

  1. Record the notebook parameters, run ID and target output path
  2. Inspect Spark UI jobs/stages for shuffle and task skew
  3. Monitor processed row counts or output freshness, not just application liveness
  4. Trace the calling pipeline or job definition run and its notebook activity

Explanation

Correct Answer

C:

Monitor processed row counts or output freshness, not just application liveness. Execution progress and business-data progress are separate measurements.

Incorrect Answers

A:

Operations needs to correlate a Spark job to the data partition it wrote. Run-level lineage connects a transformation with its published data.

B:

A notebook cell completes slowly with heavy shuffle writes. Stage metrics identify expensive redistribution work.

D:

A notebook executes interactively but no scheduled run appears. Interactive and orchestrated Spark executions have different entry points.

Question 546

An Eventstream operator investigates real-time data freshness. A scheduled execution exposes this issue: a stream source ingests events but Eventhouse receives none. What is the most defensible next action?

  1. Examine transform input/output event counts and predicate logic
  2. Compare per-destination Eventstream delivery and error metrics
  3. Monitor event-time freshness and ingestion latency
  4. Configure an appropriate freshness or lag alert threshold

Explanation

Correct Answer

B:

Compare per-destination Eventstream delivery and error metrics. Stream input acceptance does not prove successful destination routing.

Incorrect Answers

A:

A filter transform drops records unexpectedly. Transformation metrics show where records disappear.

C:

A KQL table gets events with a growing timestamp lag. End-to-end latency includes source, routing, and target ingest.

D:

Operators receive alerts only after dashboards become stale. Early operational detection needs objective freshness signals.

Question 547

An Eventstream operator investigates real-time data freshness. Data validation establishes that a KQL table gets events with a growing timestamp lag. Which technical choice fits this evidence?

  1. Monitor event-time freshness and ingestion latency
  2. Inspect source retries and stable-event deduplication telemetry
  3. Examine transform input/output event counts and predicate logic
  4. Compare per-destination Eventstream delivery and error metrics

Explanation

Correct Answer

A:

Monitor event-time freshness and ingestion latency. End-to-end latency includes source, routing, and target ingest.

Incorrect Answers

B:

Eventstream event count doubles after a producer restart. Transport replay can inflate metrics while infrastructure stays healthy.

C:

A filter transform drops records unexpectedly. Transformation metrics show where records disappear.

D:

A stream source ingests events but Eventhouse receives none. Stream input acceptance does not prove successful destination routing.
