Question 330

An analytics team chooses a Fabric data store for different source formats. The current environment exhibits the following problem: a team needs an external dataset visible in OneLake without moving bytes. Which corrective action addresses the root cause?

  1. Use a Lakehouse with Spark and OneLake storage
  2. Use a Fabric Warehouse for supported relational data engineering
  3. Create an appropriately authorized OneLake shortcut
  4. Route events into an Eventhouse KQL database

Explanation

Correct Answer

C:

Create an appropriately authorized OneLake shortcut. Choose to create an appropriately authorized OneLake shortcut; shortcuts reference source data rather than copying it.

Incorrect Answers

A:

Engineers process raw log files with PySpark and keep Delta tables. Lakehouse combines file-oriented Spark and Delta analytical tables.

B:

An enterprise requires transactional dimensional tables with extensive T-SQL transforms. Warehouse tables support SQL-oriented transactional transformations.

D:

Sensor telemetry needs near-real-time KQL search and aggregation. Eventhouse supports real-time event analysis rather than conventional OLTP.

Question 331

An engineering team uses a Fabric Copy job for incremental data movement. An acceptance test shows that a nightly copy moves the full SQL table although most rows are unchanged. Which approach best satisfies this requirement?

  1. Perform the intended initial full copy and establish incremental state
  2. Let a supported incremental Copy job maintain its own committed change state
  3. Configure supported incremental copy using a suitable watermark or CDC mode
  4. Select an increment type appropriate to the actual source column

Explanation

Correct Answer

C:

Configure supported incremental copy using a suitable watermark or CDC mode. Copy jobs can track changed records after initial loading.

Incorrect Answers

A:

A job starts with no previously synchronized state. Initial and subsequent copy modes have different scopes.

B:

A data engineer manually stores last-run state in a fragile pipeline variable. Managed state reduces custom watermark management.

D:

A rowversion source column cannot be interpreted correctly as a date. Watermark types must match source data semantics.

Question 332

An engineering team uses a Fabric Copy job for incremental data movement. The engineer has established the following constraint: a source sends deletes that must remove destination rows. Which corrective action addresses the root cause?

  1. Perform the intended initial full copy and establish incremental state
  2. Select an increment type appropriate to the actual source column
  3. Use a change-capture mode that includes delete semantics where supported
  4. Let a supported incremental Copy job maintain its own committed change state

Explanation

Correct Answer

C:

Use a change-capture mode that includes delete semantics where supported. Watermark-only append or update detection does not represent every delete.

Incorrect Answers

A:

A job starts with no previously synchronized state. Initial and subsequent copy modes have different scopes.

B:

A rowversion source column cannot be interpreted correctly as a date. Watermark types must match source data semantics.

D:

A data engineer manually stores last-run state in a fragile pipeline variable. Managed state reduces custom watermark management.

Question 333

An engineering team uses a Fabric Copy job for incremental data movement. During an operations handoff, engineers find that a job starts with no previously synchronized state. What should the administrator implement or verify?

  1. Perform the intended initial full copy and establish incremental state
  2. Use a change-capture mode that includes delete semantics where supported
  3. Let a supported incremental Copy job maintain its own committed change state
  4. Select an increment type appropriate to the actual source column

Explanation

Correct Answer

A:

Perform the intended initial full copy and establish incremental state. Initial and subsequent copy modes have different scopes.

Incorrect Answers

B:

A source sends deletes that must remove destination rows. Watermark-only append or update detection does not represent every delete.

C:

A data engineer manually stores last-run state in a fragile pipeline variable. Managed state reduces custom watermark management.

D:

A rowversion source column cannot be interpreted correctly as a date. Watermark types must match source data semantics.

Question 334

An engineering team uses a Fabric Copy job for incremental data movement. The team observes that a data engineer manually stores last-run state in a fragile pipeline variable. Which option directly handles this observed condition?

  1. Let a supported incremental Copy job maintain its own committed change state
  2. Configure supported incremental copy using a suitable watermark or CDC mode
  3. Perform the intended initial full copy and establish incremental state
  4. Select an increment type appropriate to the actual source column

Explanation

Correct Answer

A:

Let a supported incremental Copy job maintain its own committed change state. Managed state reduces custom watermark management.

Incorrect Answers

B:

A nightly copy moves the full SQL table although most rows are unchanged. Copy jobs can track changed records after initial loading.

C:

A job starts with no previously synchronized state. Initial and subsequent copy modes have different scopes.

D:

A rowversion source column cannot be interpreted correctly as a date. Watermark types must match source data semantics.

Question 335

An engineering team uses a Fabric Copy job for incremental data movement. The implementation review confirms that a rowversion source column cannot be interpreted correctly as a date. What is the most defensible next action?

  1. Use a change-capture mode that includes delete semantics where supported
  2. Configure supported incremental copy using a suitable watermark or CDC mode
  3. Select an increment type appropriate to the actual source column
  4. Let a supported incremental Copy job maintain its own committed change state

Explanation

Correct Answer

C:

Select an increment type appropriate to the actual source column. Watermark types must match source data semantics.

Incorrect Answers

A:

A source sends deletes that must remove destination rows. Watermark-only append or update detection does not represent every delete.

B:

A nightly copy moves the full SQL table although most rows are unchanged. Copy jobs can track changed records after initial loading.

D:

A data engineer manually stores last-run state in a fragile pipeline variable. Managed state reduces custom watermark management.

Question 336

A pipeline Copy activity loads data from an on-premises SQL source. A scheduled execution exposes this issue: the copy fails because the self-hosted network gateway cannot reach the source. Which action should the team take next?

  1. Verify supported gateway connectivity and database network access
  2. Tune source partitioning and copy parallelism to measured limits
  3. Use a controlled incremental extraction and idempotent destination merge
  4. Define and validate Copy activity column mappings and data types

Explanation

Correct Answer

A:

Verify supported gateway connectivity and database network access. A connector cannot move data without a permitted source route.

Incorrect Answers

B:

The source is throttled by too many concurrent partition reads. Increased concurrency may overwhelm the source rather than accelerate it.

C:

The copy repeats all historic rows on every retry. Copy execution by itself doesn't guarantee exactly-once publishing.

D:

The sink schema contains decimal columns but mapping treats them as strings. Explicit mappings avoid lossy or invalid coercion.

Question 337

A pipeline Copy activity loads data from an on-premises SQL source. Data validation establishes that the sink schema contains decimal columns but mapping treats them as strings. Which approach best satisfies this requirement?

  1. Define and validate Copy activity column mappings and data types
  2. Use a controlled incremental extraction and idempotent destination merge
  3. Tune source partitioning and copy parallelism to measured limits
  4. Add a dependent transformation activity after the copy completes

Explanation

Correct Answer

A:

Define and validate Copy activity column mappings and data types. Explicit mappings avoid lossy or invalid coercion.

Incorrect Answers

B:

The copy repeats all historic rows on every retry. Copy execution by itself doesn't guarantee exactly-once publishing.

C:

The source is throttled by too many concurrent partition reads. Increased concurrency may overwhelm the source rather than accelerate it.

D:

A pipeline Copy succeeds but required transforms are never executed. Moving bytes is different from applying business logic.

Question 338

  3. Verify supported gateway connectivity and database network access
  4. Tune source partitioning and copy parallelism to measured limits

Explanation

Correct Answer

D:

Tune source partitioning and copy parallelism to measured limits. Increased concurrency may overwhelm the source rather than accelerate it.

Incorrect Answers

A:

A pipeline Copy succeeds but required transforms are never executed. Moving bytes is different from applying business logic.

B:

The sink schema contains decimal columns but mapping treats them as strings. Explicit mappings avoid lossy or invalid coercion.

C:

The copy fails because the self-hosted network gateway cannot reach the source. A connector cannot move data without a permitted source route.
