CCP - Analytics Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

Which of the following is NOT a characteristic of Amazon Athena?

Correct Answer: Amazon Athena requires data to be loaded into a separate database before querying

Amazon Athena is a serverless query service that allows you to analyze data directly from Amazon S3 using standard SQL queries, without the need to load data into a separate database. It uses standard SQL syntax for querying data stored in Amazon S3 and eliminates the need to manage infrastructure, providing a cost-effective solution for ad-hoc data analysis. Therefore, the statement 'Amazon Athena requires data to be loaded into a separate database before querying' is not a characteristic of Amazon Athena, making it the correct answer.

Question 2

Which of the following is a data storage option that Amazon EMR can directly read from and write to?

Correct Answer: Amazon S3

Amazon S3 (Simple Storage Service) is a fully managed, scalable, and durable object storage service that can be directly read from and written to by Amazon EMR (Elastic MapReduce). EMR clusters can access data stored in S3 buckets for processing and analysis. The other options have limitations: Amazon ElastiCache is an in-memory caching service, not suitable for direct EMR integration. Amazon EFS requires additional configuration to work with EMR. Amazon DynamoDB is a NoSQL database service with specific data format requirements, making it less suitable for direct EMR read/write operations compared to S3.

Question 3

Which of the following best describes Amazon Athena's functionality?

Correct Answer: A serverless query service that allows running SQL queries on data stored in Amazon S3

Amazon Athena is a serverless query service that allows running SQL queries directly on data stored in Amazon S3, without the need to load the data into a separate database or data warehouse. It is the best fit for the given question. The other options describe different AWS services and functionalities: - Running Apache Spark applications to process data from various sources is the capability of Amazon EMR. - A fully managed ETL service for preparing and loading data for analytics from S3 to other AWS data stores describes AWS Glue. - Setting up, operating, and scaling a relational database in the cloud with SQL querying support is the functionality of Amazon RDS.
