Question 1

A data engineer must correct a design for a healthcare operations workspace. The decisive requirement is that all notebooks and Spark job definitions in the workspace must inherit the same runtime, libraries, and Spark configuration. Which choice best addresses it?

1. Use a read-optimized resource profile for the Spark workload
2. Set an environment item as the workspace default environment
3. Keep the workspace default backed by workspace-level Spark settings
4. Enable item-level compute customization and configure the workload environment
5. Use a write-optimized resource profile for the Spark workload

Correct Answer: B

Correct Answer

Answer B is correct because a workspace default environment centralizes the baseline used by items that select Workspace default.

Incorrect Answers

Answer A is incorrect because this action is appropriate when a recurring Spark job is dominated by scans and reads rather than writes. Specifically, a read-oriented resource profile targets the dominant access pattern without changing unrelated jobs, which does not resolve the decisive condition in this scenario.

Answer C is incorrect because this action is appropriate when the workspace needs one common baseline but the team does not need an environment item to own that baseline. Specifically, leaving the environment-backed default off keeps Workspace default on workspace-level Spark settings, which does not resolve the decisive condition in this scenario.

Answer D is incorrect because this action is appropriate when one notebook needs a different runtime or driver/executor sizing while the workspace baseline must stay unchanged. Specifically, item-level customization lets an environment override compute only for the workload that needs it, which does not resolve the decisive condition in this scenario.

Answer E is incorrect because this action is appropriate when a medallion-layer job spends most of its time writing Delta data and needs resources tuned for write-heavy processing. Specifically, a write-oriented profile right-sizes Spark resources for the dominant write workload, which does not resolve the decisive condition in this scenario.

Question 2

For an IoT operations solution, the organization has fixed the following constraint: the workspace needs one common baseline but the team does not need an environment item to own that baseline. Which action best satisfies the requirement?

2. Use the workspace starter pool
3. Use a custom Spark pool sized for the workload
4. Increase executor resources in the workload environment
5. Increase driver resources in the workload environment

Correct Answer: B

Correct Answer

Answer B is correct because the starter pool minimizes startup friction for ordinary development workloads. This directly addresses the relevant Fabric behavior while preserving the other stated constraints.

Incorrect Answers

Answer A is incorrect because this action is appropriate when several independent notebooks must run together and one oversized job is monopolizing the shared Spark capacity. Specifically, right-sizing the single job preserves capacity for concurrent workloads, which does not resolve the decisive condition in this scenario.

5. Add extra nodes to the Airflow custom pool

Correct Answer: B

Correct Answer

Answer B is correct because the starter pool is the default instant runtime suited to development and intermittent use.

Incorrect Answers

Answer A is incorrect because this action is appropriate when Airflow tasks spend substantial time waiting for Fabric item runs and should release worker resources during the wait. Specifically, deferrable operators free resources while waiting for external Fabric item completion, which does not resolve the decisive condition in this scenario.

Answer C is incorrect because this action is appropriate when production DAGs require controlled sizing and an always-on pool rather than the default developer runtime. Specifically, a custom pool provides configurable node size, autoscale, and extra nodes, which does not resolve the decisive condition in this scenario.

Answer D is incorrect because this action is appropriate when DAG concurrency varies significantly and the pool should add or remove nodes with demand. Specifically, autoscale adjusts custom-pool nodes to changing workflow demand, which does not resolve the decisive condition in this scenario.

Answer E is incorrect because this action is appropriate when the current production pool is stable but needs more concurrent workers for additional DAGs. Specifically, extra nodes increase worker capacity without replacing the whole runtime model, which does not resolve the decisive condition in this scenario.

Question 26

A data engineer must correct a design for a multi-team Fabric deployment. The decisive requirement is that Airflow DAGs must invoke Fabric items without storing a client secret. Which choice best addresses it?

1. Use a custom pool when production DAG availability requires an always-on runtime
2. Use a Fabric connection authenticated with workspace identity
3. Grant the workspace identity access to the target workspace or item
4. Enable Fabric connections on the Airflow job artifact
5. Add the existing Fabric connection to the Airflow job

Correct Answer: B

Correct Answer

Answer B is correct because workspace identity provides managed authentication for supported Fabric connections. This directly addresses the relevant Fabric behavior while preserving the other stated constraints.

Incorrect Answers

Answer A is incorrect because this action is appropriate when a critical DAG should avoid the development-oriented pool that shuts down after inactivity. Specifically, the custom pool is intended for production scenarios that need explicit runtime behavior, which does not resolve the decisive condition in this scenario.

Answer C is incorrect because this action is appropriate when authentication succeeds but the Airflow task receives access denied on the Fabric target. Specifically, the managed identity still requires authorization on the resource it invokes, which does not resolve the decisive condition in this scenario.

Answer D is incorrect because this action is appropriate when a configured Fabric connection exists but the Airflow job cannot use it. Specifically, the Airflow artifact must have Fabric connections enabled before DAGs can use the configured connection, which does not resolve the decisive condition in this scenario.

Answer E is incorrect because this action is appropriate when the connection is configured centrally but does not appear to the DAG as an available connection. Specifically, the job must include the desired Fabric connection before the DAG can reference it, which does not resolve the decisive condition in this scenario.
