    For the question “A data engineering team needs an efficient method to analyze historical data for a market research project. The data resides in various AWS services, including Amazon RDS for PostgreSQL, Amazon DynamoDB, and Amazon S3, along with logs stored in Amazon CloudWatch. The team plans to execute a one-time query that requires joining this data. What is the MOST cost-effective solution that the data engineering team can implement to meet this requirement?”

    the explanation for one of the wrong answers “The option that says: <strong style=”font-family: inherit; font-size: inherit;”>Configure Amazon Redshift Spectrum to query data in DynamoDB, Amazon RDS for PostgreSQL, and S3, with a separate process for CloudWatch Logs analysis is incorrect because Redshift Spectrum does not support direct querying of CloudWatch Logs. Moreover, having a separate process for CloudWatch Logs analysis would complicate the overall solution and increase costs.”


    is misleading as it implies that Redshift Spectrum can query <strong style=”font-family: inherit; font-size: inherit;”>DynamoDB, Amazon RDS for PostgreSQL when in reality it can only query S3. The explanation should specifically say that Redshift Spectrum can only query S3.

    Hi or-3,

    Thank you for posting here.

    We appreciate your attention to detail and your correct observation. Amazon Redshift Spectrum cannot directly query data in DynamoDB, Amazon RDS for PostgreSQL, or CloudWatch Logs. It is specifically designed for querying data stored in Amazon S3. Any assertion about configuring Redshift Spectrum to directly access data from DynamoDB, RDS for PostgreSQL, or CloudWatch Logs would indeed be incorrect.

    Thank you for bringing this to our attention. We will make necessary updates regarding this item. Please let us know if there are any other areas where we can provide further clarification or assistance.

    Cheers,

    Irene @Tutorials Dojo
