The answer is the COPY command from Amazon S3, the COPY command from DynamoDB, and Kinesis Data Firehose. These three services are correct because they directly load data into Redshift tables without intermediate steps: the COPY command efficiently bulk-loads from flat files in S3 or from an existing DynamoDB table, while Kinesis Data Firehose streams real-time data directly into Redshift. On the AWS Certified Data Engineer Associate DEA-C01 exam, this question tests your understanding of native Redshift ingestion methods versus indirect tools; a common trap is confusing S3 Transfer Acceleration, which only speeds up uploads to S3, or AWS DMS, which can target Redshift but is not a direct load service. Remember the memory tip: "S3, DDB, and Firehose go straight into Redshift rows."
DEA-C01 Data Operations and Support Practice Question
This DEA-C01 practice question tests your understanding of data operations and support. 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.
A data engineer is migrating a legacy data warehouse to Amazon Redshift. The engineer needs to load data from multiple sources efficiently. Which THREE services can be used to load data into Redshift? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the COPY command to load from Amazon DynamoDB.
Options A, B, and D are correct: COPY from S3, COPY from DynamoDB, and Kinesis Data Firehose directly load into Redshift. Option C is wrong because S3 Transfer Acceleration is for uploading to S3, not loading into Redshift. Option E is wrong because AWS DMS can migrate data but is not a direct load service for Redshift; it can load into Redshift as a target.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use the COPY command to load from Amazon DynamoDB.
Why this is correct
COPY can load data from DynamoDB tables.
Related concept
Read the scenario before looking for a memorised answer.
✓
Use Kinesis Data Firehose to deliver data directly to Redshift.
Why this is correct
Firehose can stream data into Redshift via S3 COPY or direct insertion.

Read the scenario before looking for a memorised answer.
✗
Use AWS DMS to replicate data continuously.
Why it's wrong here
DMS is a migration service, not a direct load method; it can target Redshift but is not as efficient as COPY.
✗
Use S3 Transfer Acceleration.
Why it's wrong here
Transfer Acceleration only speeds up uploads to S3, not loading to Redshift.
✓
Use the COPY command to load from Amazon S3.
Why this is correct
COPY is the primary method for bulk loading from S3.

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.
