DEA-C01 Data Ingestion and Transformation Practice Question
Which THREE factors should be considered when choosing between AWS Glue and Amazon EMR for data transformation? (Choose three.)
⚠ Common exam trap
Watch out — candidates often confuse Glue's automatic schema discovery with automatic data storage, or assume EMR is the only option for streaming, when in fact both services support streaming but with different levels of control and operational overhead.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EMR allows fine-grained control over cluster configuration and software.
Amazon EMR provides full control over cluster configuration, including the ability to customize software, install libraries, and tune Spark, Hadoop, or Hive parameters. This fine-grained control is essential for complex or specialized data transformation pipelines that require specific versions or custom configurations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Glue automatically stores data in S3 after transformation.
Why it's wrong here
Both can write to S3; it's not a differentiator.
- ✓
EMR allows fine-grained control over cluster configuration and software.
Why this is correct
EMR provides flexibility to install custom software and tune clusters.
- ✗
EMR supports real-time stream processing with Spark Streaming.
Why it's wrong here
Both can do streaming, but Glue Streaming is also available.
- ✓
Glue is serverless, reducing operational overhead.
Why this is correct
Glue automatically manages resources; EMR requires cluster management.
- ✓
Glue integrates natively with the Glue Data Catalog for schema management.
Why this is correct
Glue Data Catalog is a central metadata repository used by Glue jobs.
