Which of the following is NOT a primary format supported for querying by Amazon Athena?

• A. CSV
• B. Parquet
• C. ORC
• D. HTML

Answer: (D)

Amazon Athena is a serverless interactive query service that allows users to analyze data in Amazon S3 using standard SQL. It supports various formats optimized for querying, enabling efficient data analysis. CSV (Comma-Separated Values), Parquet, and ORC (Optimized Row Columnar) are all highly recognized formats that Athena can efficiently process. CSV is a widely used format for data exchange, while Parquet and ORC are columnar storage formats specifically designed for big data analytics, allowing for optimization in both storage efficiency and query performance. In contrast, HTML is primarily a markup language used for creating web pages and is not intended for data analysis. It does not provide the necessary structure or efficiency for querying in a data analytics context, which explains why it is not among the primary supported formats for Amazon Athena.
