AWS Certified Database – Specialty — Question 59

A company is writing a new survey application to be used with a weekly televised game show. The application will be available for 2 hours each week. The company expects to receive over 500,000 entries every week, with each survey asking 2-3 multiple choice questions of each user. A Database Specialist needs to select a platform that is highly scalable for a large number of concurrent writes to handle the anticipated volume.
Which AWS services should the Database Specialist consider? (Choose two.)

Answer options

Correct answer: A, E

Explanation

Amazon DynamoDB is a fully managed NoSQL database that provides fast and predictable performance with seamless scalability, making it suitable for the high write throughput required. Amazon ElastiCache, as an in-memory data store, can also handle a large volume of concurrent writes effectively. The other options, such as Amazon Redshift and Amazon Neptune, are not optimized for high write concurrency, while Amazon Elasticsearch Service is better suited for search and analytics rather than handling large volumes of concurrent writes.
