Question11: A company is creating an architecture for a mobile app that requires minimal latency for its users. The company's architecture consists of Amazon EC2 instances behind an Application Load Balancer running in an Auto Seating group The EC2 instances connect to Amazon RDS Application beta testing showed there was a slowdown when reading the data However, the metrics indicate that the EC2 instances do not cross any CPU utilization thresholds How can this issue be addressed?

Question12: A company has deployed a multiplayer game for mobile devices. The game requires live location tracking of players based on latitude and longitude. The data store for the game must support rapid updates and retrieval of locations.
The game uses an Amazon RDS for PostgreSQL DB instance with read replicas to store the location data.

Question14: A company hosts an application on AWS. The application interacts with an Amazon DynamoDB table that has
10 read capacity units (RCUs) Data from Amazon CloudWatch alarms shows that throttling is occurring on read requests to the DynamoDB table. The company needs to prevent this issue from happening in the future as the application continues to grow.
What should a solutions architect recommend to meet these requirements?

Question15: A company processes large amounts of data. The output data is stored in Amazon S3 Standard storage in an S3 bucket, where it is analyzed for 1 month. The data must remain immediately accessible after the 1-month analysis period Which storage solution meets these requirements MOST cost-effectively?

Question16: A company is hosting an application in its own data center The application uses Amazon S3 for data storage The application transfers several hundred terabytes of data every month to and from Amazon S3 The company needs to minimize the cost of this data transfer Which solution meets this requirement?

Question17: A company is running a highly sensitive application on Amazon EC2 backed by an Amazon RDS database Compliance regulations mandate that all personally identifiable information (Pll) be encrypted at rest Which solution should a solutions architect recommend to meet this requirement with the LEAST amount of changes to the infrastructure?

Question18: A company has applications that are deployed in multiple AWS Regions. The applications use an architecture that is based on Amazon EC2, Amazon Elastic Block Store (Amazon EBS), Amazon Elastic File System (Amazon EFS). and Amazon DynamoDB The company lacks a mechanism for centralized data backup. A solutions architect must centralize data backup with the least possible operational effort.
What should the solutions architect do to meet these requirements?

Question19: An application runs on Amazon EC2 instances across multiple Availability Zones The instances run in an Amazon EC2 Auto Scaling group behind an Application Load Balancer The application performs best when the CPU utilization of the EC2 instances is at or near 40% What should a solutions architect do to maintain the desired performance across all instances in the group?

Question20: A solutions architect must design a solution that uses Amazon CloudFront with an Amazon S3 origin to store a static website. The company's security policy requires that all website traffic be inspected by AWS WAF How should the solutions architect comply with these requirements?

Question21: A company is designing a new application that runs in a VPC on Amazon EC2 instances.
