A company stores third-party provider data as objects in Amazon S3 and ran an AWS Glue crawler to populate the data catalog. The crawler produced multiple tables, but the company expected only a single table. Which combination of changes will ensure the AWS Glue crawler creates only one table? (Choose two.)

Correct answer: Ensure that the object format, compression type, and schema are the same for each object., Ensure that the structure of the prefix for each S3 object name is consistent..
Why this is the answer
AWS Glue crawlers group data into tables based on several factors, including schema, data format, compression type, and S3 path structure. To ensure a single table is created, all objects must share a consistent schema, data format (e.g., Parquet, CSV), and compression type (e.g., GZIP, Snappy). Inconsistent formats or compression types will lead the crawler to infer separate tables. Additionally, a consistent S3 prefix structure helps the crawler identify related data. If objects are scattered across disparate S3 paths, the crawler might treat them as distinct datasets. Therefore, unifying these characteristics guides the crawler to consolidate the data into a single, logical table.
