DEA-C01 Data Ingestion and Transformation Practice Question

This DEA-C01 practice question tests your understanding of data ingestion and transformation. 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.

Match each AWS data migration tool to its primary function.

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

A
AWS Database Migration Service (DMS): Migrates databases to AWS with minimal downtime
AWS DMS is designed for migrating databases to AWS while minimizing downtime, supporting both homogeneous and heterogeneous migrations.
B
AWS Snowball: Transfers large datasets via physical devices
AWS Snowball uses physical storage devices to transfer large amounts of data to/from AWS, bypassing slow or unreliable networks.
C
AWS DataSync: Automates and accelerates online data transfer to/from AWS storage
AWS DataSync automates and accelerates moving data between on-premises storage and AWS storage services like S3 or EFS.
D
AWS Database Migration Service (DMS): Transfers large datasets via physical devices
Why wrong: Incorrect — AWS DMS is for database migration, not physical device transfer; AWS Snowball handles physical data transfer.
E
AWS Snowball: Migrates databases to AWS with minimal downtime
Why wrong: Incorrect — AWS Snowball is for bulk data transfer via devices, not for live database migration; AWS DMS is the correct tool.
F
AWS DataSync: Converts database schema to target platform
Why wrong: Incorrect — AWS DataSync is for data transfer, not schema conversion; the AWS Schema Conversion Tool (SCT) handles schema conversion.

Correct answer & explanation

✓

AWS Database Migration Service (DMS): Migrates databases to AWS with minimal downtime

AWS DMS migrates databases with minimal downtime; AWS Snowball transfers large datasets physically; AWS DataSync automates online data transfer. Common confusions include swapping tool functions or attributing schema conversion to DataSync instead of SCT.

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

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
