Microsoft DP-700 Practice Test 33

Question 320

Consider this Microsoft Fabric case: A pipeline copies a large trusted Delta dataset multiple times for consumers that could use a reference. What measured result demonstrates that the requirement is satisfied?

  1. Physical copies decrease and consumers still read current data.
  2. Physical plan uses broadcast and shuffle bytes decrease.
  3. The file and directory counts decrease without losing records.
  4. File count and scan overhead decrease without changing data.

Explanation

Correct Answer

A:

Storage plus parity validate simplification. This observation directly tests the expected outcome.

Incorrect Answers

B:

Plan and bytes verify the mechanism.

C:

Layout metrics validate the correction.

D:

Physical metrics and row parity prove compaction.

Question 321

Consider this Microsoft Fabric case: A large feed requires custom Python parsing, Spark joins, and project-specific libraries. What measured result demonstrates that the requirement is satisfied?

  1. Source file modifications are visible through the reference.
  2. The curated Delta table reflects tested joins and rejected parse cases.
  3. The Delta schema and sample values use correct data types.
  4. Spark and SQL read matching registered Delta records.

Explanation

Correct Answer

B:

Correct processed and rejected rows prove execution. This observation directly tests the expected outcome.

Incorrect Answers

A:

No duplicate stored replica is required.

C:

Value and schema checks validate parsing.

D:

Both engines retrieving equivalent rows confirms cross-engine availability.

Question 322

An expensive warehouse query requires operator analysis without repeatedly running against production data. What should the engineer check to confirm that the intended behavior was achieved?

  1. The plan distributes execution and preserves results.
  2. Plan estimates better approximate actual row counts.
  3. The sort node processes fewer rows after revision.
  4. The plan reveals the large scan or sort for review.

Explanation

Correct Answer

D:

Plan availability validates safe diagnosis. This observation directly tests the expected outcome.

Incorrect Answers

A:

Plan evidence and correctness establish suitability.

B:

Estimated-versus-actual data verifies impact. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: The plan reveals the large scan or sort for review.

C:

Operator metrics verify the change.

Question 323

A Delta workload has logically deleted rows retained in old physical files. Which postchange result provides the strongest validation of success?

  1. Result payload decreases with identical chart figures.
  2. Controlled recent-data benchmarks show lower latency.
  3. File count and scan overhead decrease without changing data.
  4. Version tests pass after lower obsolete storage usage.

Explanation

Correct Answer

D:

Recovery safety and capacity prove housekeeping. This observation directly tests the expected outcome.

Incorrect Answers

A:

Transferred bytes and parity validate optimization.

B:

Comparable latency and freshness prove benefit.

C:

Physical metrics and row parity prove compaction.

Question 324

Consider this Microsoft Fabric case: Nested JSON adds a new field but old curated columns must remain aligned. What measured result demonstrates that the requirement is satisfied?

  1. The aggregate grain and totals match the staging query.
  2. A source update becomes visible in mirrored rows without a manual Copy job.
  3. Old columns match their baseline and new columns populate on modern rows.
  4. All input rows are accounted for across both outputs.

Explanation

Correct Answer

C:

Cross-version checks validate compatibility. This observation directly tests the expected outcome.

Incorrect Answers

A:

Group counts and measures verify the materialization.

B:

Change propagation is stronger evidence than initial table creation.

D:

Conservation and rejection codes prove handling.

Question 325

Consider this Microsoft Fabric case: A KQL query parses expensive dynamic payloads before filtering to one device. What measured result demonstrates that the requirement is satisfied?

  1. Shuffle bytes fall and grouped results remain equal.
  2. Same target-device results are returned with less work.
  3. The plan distributes execution and preserves results.
  4. Workers aggregate and only small results reach the driver.

Explanation

Correct Answer

B:

Scan diagnostics and output equality verify improvement. This observation directly tests the expected outcome.

Incorrect Answers

A:

Execution evidence validates the rewrite.

C:

Plan evidence and correctness establish suitability.

D:

Driver memory plus measure equality prove improvement.

Question 326

A factory reports production units in fixed nonoverlapping five-minute reporting windows. Which observation most directly verifies the intended outcome after the appropriate action?

  1. Statistics and policy state show the intended seven-day acceleration window.
  2. One event is observed in each intended sink with consistent identifiers.
  3. Known events contribute to the expected overlapping window outputs.
  4. Every sample event contributes to the intended single window.

Explanation

Correct Answer

D:

Boundary records confirm nonoverlapping grouping. This observation directly tests the expected outcome.

Incorrect Answers

A:

Configured cache scope and observed statistics establish the limit.

B:

Cross-destination correspondence validates fan-out. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: Every sample event contributes to the intended single window.

C:

Window memberships validate hop and duration.

Question 327

A KQL query suddenly fails with an unknown-column error after the source payload renamed its status field. Which postchange result provides the strongest validation of success?

  1. The logical plan resolves every intended column and sample output is correct.
  2. The query compiles and returns expected join results for a fixture.
  3. The revised query resolves and returns the intended status values.
  4. Valid values convert exactly and invalid values are handled explicitly.

Explanation

Correct Answer

C:

Schema inspection and output correctness validate repair. This observation directly tests the expected outcome.

Incorrect Answers

A:

Schema resolution and data validation confirm repair.

B:

Parse success and result correctness validate syntax repair.

D:

Boundary fixtures verify the correction.

Question 328

A team reruns manual ZORDER commands whenever the table's preferred filter columns evolve. Which postchange result provides the strongest validation of success?

  1. New cluster metadata remains set after maintenance.
  2. The execution plan scans only relevant date partitions.
  3. Source-side query contains the filter with correct output.
  4. Shuffle bytes fall and grouped results remain equal.

Explanation

Correct Answer

A:

Persistence distinguishes the strategy. This observation directly tests the expected outcome.

Incorrect Answers

B:

Pruned partitions verify effectiveness. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: New cluster metadata remains set after maintenance.

C:

Folded query and row parity prove pushdown.

D:

Execution evidence validates the rewrite.

Question 329

A bronze feed must load at 06:00 in a particular business time zone every working day. What should the engineer check to confirm that the intended behavior was achieved?

  1. Scheduled run history shows starts at the intended local business times.
  2. Run history shows the Copy and Notebook activity dependencies and correct failure path.
  3. Fact processing starts only after both dimension branches finish successfully.
  4. Runs with two parameter values read from their corresponding intended paths.

Explanation

Correct Answer

A:

Timestamps converted to the intended time zone validate cadence. This observation directly tests the expected outcome.

Incorrect Answers

B:

Activity-level history confirms the designed control flow, not just that a notebook exists.

C:

Activity timestamps and prerequisites validate coordinated fan-in.

D:

Parameter-to-actual-path mapping validates runtime substitution.

Question 330

Consider this Microsoft Fabric case: A Spark streaming job writes to Delta and must keep output progress safe if a microbatch is retried. What measured result demonstrates that the requirement is satisfied?

  1. An intentionally replayed event ID does not increase the curated distinct event count.
  2. An injected restart does not duplicate committed business events.
  3. Fresh sample events reach the Eventhouse table and are queryable.
  4. Malformed fixtures appear in the failure path and valid events reach the main sink.

Explanation

Correct Answer

B:

Replay invariance validates restart safety. This observation directly tests the expected outcome.

Incorrect Answers

A:

Controlled duplicate injection validates deduplication.

C:

Event-to-table latency and content validate the route.

D:

Conservation across paths validates resilience.
