1. A data architect has designed a system in which two Structured Streaming jobs will concurrently write to a single bronze Delta table. Each job is subscribing to a different topic from an Apache Kafka source, but they will write data with the same schema. To keep the directory structure simple, a data engineer has decided to nest a checkpoint directory to be shared by both streams.
The proposed directory structure is displayed below:

Which statement describes whether this checkpoint directory structure is valid for the given scenario and why?

A) No; only one stream can write to a Delta Lake table.
B) Yes; both of the streams can share a single checkpoint directory.
C) No; each of the streams needs to have its own checkpoint directory.
D) No; Delta Lake manages streaming checkpoints in the transaction log.
E) Yes; Delta Lake supports infinite concurrent writers.

2. In order to facilitate near real-time workloads, a data engineer is creating a helper function to leverage the schema detection and evolution functionality of Databricks Auto Loader. The desired function will automatically detect the schema of the source directly, incrementally process JSON files as they arrive in a source directory, and automatically evolve the schema of the table when new fields are detected.
The function is displayed below with a blank:

Which response correctly fills in the blank to meet the specified requirements?

A)

B)

C)

D)

E)

3. A data engineer needs to install the PyYAML Python package within an air-gapped Databricks environment. The workspace has no direct internet access to PyPI. The engineer has downloaded the .whl file locally and wants it available automatically on all new clusters. Which approach should the data engineer use?

A) Upload the PyYAML .whl file to a Unity Catalog Volume, ensure it's allow-listed, and create a cluster-scoped init script that installs it from that path.
B) Add the .whl file to Databricks Git Repos and assume automatic installation.
C) Set up a private PyPI repository and install via pip index URL.
D) Upload the PyYAML .whl file to the user home directory and create a cluster-scoped init script to install it.

4. Which statement describes integration testing?

A) Validates behavior of individual elements of your application
B) Validates an application use case
C) Validates interactions between subsystems of your application
D) Requires an automated testing framework
E) Requires manual intervention

5. Which Python variable contains a list of directories to be searched when trying to locate required modules?

A) sys.path
B) pypi.path
C) os.path
D) importlib.resource path
E) pylib.source
