Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon RDS: Fully managed relational database service supporting multiple database engines
Why this is correct
Amazon RDS provides managed relational databases with support for MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB.
Amazon DynamoDB: Fully managed NoSQL key-value and document database, serverless
Why this is correct
DynamoDB is a serverless NoSQL database offering single-digit millisecond performance at any scale.
Amazon Redshift: Petabyte-scale data warehouse service for analytics
Why this is correct
Redshift is a fast, fully managed data warehouse that uses columnar storage to handle large-scale analytics.
Amazon ElastiCache: In-memory caching service supporting Redis and Memcached
Why this is correct
ElastiCache provides managed in-memory caches to improve application performance by offloading reads from databases.
Amazon RDS: Fully managed NoSQL key-value database
Why it's wrong here
