Azure Databricks is the correct choice because it provides a unified analytics platform built on Apache Spark, optimized for big data processing and machine learning, and it offers collaborative notebooks that allow data engineers and data scientists to write and execute Spark code interactively. This service is purpose-built for running Azure managed Apache Spark with collaborative notebooks, enabling teams to share code, visualizations, and results in real time. On the Microsoft Azure Fundamentals AZ-900 exam, this question tests your understanding of which PaaS solution handles big data and advanced analytics workloads—a common trap is confusing Azure Databricks with Azure Synapse Analytics, but remember that Databricks is specifically the Spark-based collaborative notebook environment, while Synapse focuses more on data warehousing and SQL-based analytics. A helpful memory tip: think of Databricks as “data bricks” for building Spark analytics, and associate the word “notebooks” directly with Databricks to lock in the correct answer.
AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which Azure service provides a platform for running Apache Spark analytics for big data processing with collaborative notebooks?
Why wrong: HDInsight supports multiple open-source frameworks including Spark; Databricks is optimized specifically for Spark with collaborative notebooks.
B
Azure Databricks
Azure Databricks is an optimized Apache Spark analytics platform with collaborative notebooks for big data and ML.
C
Azure Synapse Analytics
Why wrong: Synapse Analytics integrates Spark and SQL for data warehousing; Databricks is specifically the collaborative Spark platform.
D
Azure Machine Learning
Why wrong: Azure ML handles the full ML lifecycle; Databricks provides the Spark analytics environment.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Databricks
Azure Databricks is correct because it provides a unified analytics platform built on Apache Spark, optimized for big data processing and machine learning. It offers collaborative notebooks that allow data engineers and data scientists to write and execute Spark code interactively, making it the ideal service for this specific use case.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure HDInsight with Azure Databricks because both support Apache Spark, but HDInsight lacks the native collaborative notebook experience and is more of a traditional cluster management service.
Detailed technical explanation
How to think about this question
Azure Databricks leverages Apache Spark clusters with optimized runtime for performance, and its collaborative notebooks support multiple languages (Python, Scala, SQL, R) with built-in version control and real-time collaboration. Under the hood, it uses a managed Spark engine with auto-scaling and Delta Lake for ACID transactions on data lakes, which is critical for production big data workloads. A real-world scenario is a data team using Databricks notebooks to process terabytes of streaming data from IoT devices, where the collaborative environment allows simultaneous development and debugging.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
