Databricks Certified Data Engineer Associate Exam Sample Questions (Q204-Q209):

NEW QUESTION # 204
A new data engineering team team. has been assigned to an ELT project. The new data engineering team will need full privileges on the database customers to fully manage the project.
Which of the following commands can be used to grant full permissions on the database to the new data engineering team?

Answer: E

Explanation:
Explanation
To grant full privileges on the database "customers" to the new data engineering team, you can use the GRANT ALL PRIVILEGES command as shown in option E. This command provides the team with all possible privileges on the specified database, allowing them to fully manage it.


NEW QUESTION # 205
A data engineer has a PySpark DataFrame events_dfwhich contains a nested devicestruct, which itself includes a nested locationstruct, as shown:

The goal is to flatten the nested fields into root-level columns while keeping the event identifiers and timestamp.
Which PySpark expression achieves this?

Answer: A

Explanation:
Dot notation selects the scalar fields inside both device and its nested location struct as root-level columns while retaining event_id and event_ts. Option D expands only device's first level, leaving location nested.


NEW QUESTION # 206
A data engineer needs to conduct Exploratory Data Analysis (EDA) on data residing in a database within the company's custom-defined cloud network. The data engineer is using SQL for this task.
Which type of SQL Warehouse will enable the data engineer to process large numbers of queries quickly and cost-effectively?

Answer: C

Explanation:
A SQL Serverless Warehouse is the most suitable option for running SQL-based exploratory data analysis at scale while minimizing operational and cost overhead. Serverless SQL warehouses are fully managed by Databricks, meaning Databricks automatically provisions and scales compute resources, applies Photon acceleration, and optimizes query execution without requiring the user to manage infrastructure. This makes them ideal for workloads involving large numbers of ad hoc or interactive SQL queries, which is common during EDA. Because the data resides in a custom-defined cloud network, serverless SQL warehouses can still securely access governed data when Unity Catalog and networking requirements are satisfied. All- purpose clusters (option A) are designed for collaborative development and mixed workloads, not cost- efficient high-concurrency SQL querying. Classic SQL warehouses (option D) are legacy and lack the performance and cost optimizations of newer serverless offerings. Pro SQL warehouses (option B) require user-managed sizing decisions, whereas serverless warehouses optimize both performance and cost automatically. Databricks documentation recommends SQL Serverless Warehouses for fast, scalable, and cost-effective SQL analytics.

NEW QUESTION # 207
Which of the following is a benefit of the Databricks Lakehouse Platform embracing open source technologies?

Answer: C

Explanation:
One of the benefits of the Databricks Lakehouse Platform embracing open source technologies is that it avoids vendor lock-in. This means that customers can use the same open source tools and frameworks across different cloud providers, and migrate their data and workloads without being tied to a specific vendor. The Databricks Lakehouse Platform is built on open source projects such as Apache Spark™, Delta Lake, MLflow, and Redash, which are widely used and trusted by millions of developers. By supporting these open source technologies, the Databricks Lakehouse Platform enables customers to leverage the innovation and community of the open source ecosystem, and avoid the risk of being locked into proprietary or closed solutions. The other options are either not related to open source technologies (A, B, C, D), or not benefits of the Databricks Lakehouse Platform (A, B).
