DEA-C01 Data Ingestion and Transformation Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Create S3 bucket, then register it in Lake Formation, then set up administrators, then define schema in Glue Catalog, then grant access to users

  Why this is correct

  This is the correct order because the S3 bucket must exist before it can be registered, administrators must be set up to manage the lake, the schema defines the data structure, and access is granted after the schema is ready.

• ✗

  Set up administrators, then create S3 bucket, then register it in Lake Formation, then define schema in Glue Catalog, then grant access to users

  Why it's wrong here

  This is incorrect because administrators cannot effectively manage the lake without a registered bucket; the bucket creation and registration should precede administrator setup.

• ✗

  Create S3 bucket, then define schema in Glue Catalog, then register it in Lake Formation, then set up administrators, then grant access to users

  Why it's wrong here

  This is incorrect because the schema definition should happen after the bucket is registered in Lake Formation, as the schema is tied to the registered location; registering after schema definition complicates the setup.

• ✗

  Register S3 bucket in Lake Formation, then create S3 bucket, then set up administrators, then define schema in Glue Catalog, then grant access to users

  Why it's wrong here

  This is incorrect because you cannot register a bucket that does not exist; the bucket must be created first before it can be registered in Lake Formation.
