Amazon (SAA-C03) Exam Questions And Answers page 5
A company has a mobile game that reads most of its metadata from an Amazon RDS DB instance. As the game increased in popularity developers noticed slowdowns related to the game s metadata load times. Performance metrics indicate that simply scaling the database will not help. A solutions architect must explore all options that include capabilities for snapshots replication and sub-millisecond response times.

A company has a multi-tier application deployed on several Amazon EC2 instances in an Auto Scaling group. An Amazon RDS for Oracle instance is the application, data layer that uses Oracle-specific PSQL functions. Traffic to the application has been steadily increasing. This is causing the EC2 instances to become overloaded and RDS instance to run out of storage. The Auto Scaling group does not have any scaling metrics and defines the minimum healthy instance count only. The company predicts that traffic will continue to increase at a steady but unpredictable rate before leveling off.

A company has an API-based inventory reporting application running on Amazon EC2 instances. The application stores information in an Amazon DynamoDB table. The company s distribution centers have an on-premises shipping application that calls an API to update the inventory before printing shipping labels. The company has been experiencing application interruptions several times each day, resulting in lost transactions.

A company has an application that calls AWS Lambda functions. A code review shows that database credentials are stored in a Lambda function s source code, which violates the company s security policy. The credentials must be securely stored and must be automatically rotated on an ongoing basis to meet security policy requirements.
