AWS Certified Solutions Architect – Associate (SAA-C02) — Question 108

A solutions architect is designing a mission-critical web application. It will consist of Amazon EC2 instances behind an Application Load Balancer and a relational database. The database should be highly available and fault tolerant.
Which database implementations will meet these requirements? (Choose two.)

Answer options

• A. Amazon Redshift
• B. Amazon DynamoDB
• C. Amazon RDS for MySQL
• D. MySQL-compatible Amazon Aurora Multi-AZ
• E. Amazon RDS for SQL Server Standard Edition Multi-AZ

Correct answer: D, E

Explanation

The correct answers, D and E, represent database implementations that are designed for high availability and fault tolerance through Multi-AZ deployments. Options A and B do not meet the requirements as Amazon Redshift is a data warehouse solution and Amazon DynamoDB is a NoSQL database, neither of which provide traditional relational database capabilities with the necessary availability features.
