Data Ingestion and TransformationhardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the Glue job’s IAM role lacks the s3:PutObject permission on the processed bucket. This is the most likely cause because the error specifically states the job cannot write to S3, and the CloudFormation stack outputs confirm the bucket names exist, but the role is typically scoped to read-only access on the raw bucket by default. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding of least-privilege IAM policies and how Glue jobs interact with S3—a common trap is assuming the job inherits write access from the stack outputs, when in reality each bucket requires explicit permissions. The exam often pairs this with a CloudFormation template that only grants s3:GetObject on the raw bucket, making the write failure a classic “permission denied” rather than a bucket policy or network issue. Memory tip: think “Put to Process” — if the job can’t write, check for s3:PutObject on the processed bucket.

DEA-C01 Data Ingestion and Transformation Practice Question

This DEA-C01 practice question tests your understanding of data ingestion and transformation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

Refer to the exhibit. A CloudFormation stack outputs the Glue job name and S3 bucket names. The Glue job transforms CSV files from the raw bucket to Parquet in the processed bucket. However, the Glue job is failing with an error that it cannot write to the processed bucket. What is the most likely cause?

Clue words in this question

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

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Answer choices

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

The Glue job does not have permission to write to the processed bucket

The Glue job's IAM role likely does not have s3:PutObject permission on the processed bucket. The CloudFormation outputs show the bucket names, but the role may only have read access to raw. The error is write-related, not read.

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.

  • The Glue job does not have permission to write to the processed bucket

    Why this is correct

    Missing s3:PutObject on processed-bucket.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • The raw data bucket is in a different region

    Why it's wrong here

    Would cause read failure, not write.

  • The Glue job is not using the correct worker type

    Why it's wrong here

    Worker type affects performance, not permissions.

  • The Glue job is using an incorrect file format

    Why it's wrong here

    Would cause conversion error, not permission error.

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.
