Topic 1 Question 124
2 つ選択A finance company receives data from third-party data providers and stores the data as objects in an Amazon S3 bucket.
The company ran an AWS Glue crawler on the objects to create a data catalog. The AWS Glue crawler created multiple tables. However, the company expected that the crawler would create only one table.
The company needs a solution that will ensure the AVS Glue crawler creates only one table.
Which combination of solutions will meet this requirement?
Ensure that the object format, compression type, and schema are the same for each object.
Ensure that the object format and schema are the same for each object. Do not enforce consistency for the compression type of each object.
Ensure that the schema is the same for each object. Do not enforce consistency for the file format and compression type of each object.
Ensure that the structure of the prefix for each S3 object name is consistent.
Ensure that all S3 object names follow a similar pattern.

To ensure that the AWS Glue crawler creates only one table and handles the object format, compression type, schema, and prefix structure consistently: Ensure Consistent Object Format, Compression Type, Schema, and Prefix Structure
Consistent Object Format:
- Ensure that all objects in the S3 bucket are in the same format (e.g., CSV, JSON, Parquet).
Consistent Compression Type:
- Ensure that all objects use the same compression type (e.g., GZIP, Snappy).
Consistent Schema:
- Ensure that all objects have the same schema (i.e., the same fields with the same data types).
Consistent Prefix Structure:
- Ensure that all objects follow a consistent naming convention and prefix structure in the S3 bucket (e.g.,
s3://your-bucket/path/to/data/).
- Ensure that all objects follow a consistent naming convention and prefix structure in the S3 bucket (e.g.,

D focuses on the S3 prefix structure, which affects partitioning but not the creation of a single table. Consistency in file format and schema is much more important in determining how AWS Glue handles the data.
