An online shopping application accesses an Amazon RDS Multi-AZ DB instance. Database performance is slowing down the application. After upgrading to the next-generation instance type, there was no significant performance improvement. Analysis shows approximately 700 IOPS are sustained, common queries run for long durations and memory utilization is high. Which application change should a solutions architect recommend to resolve these issues?
Question 402
A company is preparing to store confidential data in Amazon S3. For compliance reasons, the data must be encrypted at rest. Encryption key usage must be logged for auditing purposes. Keys must be rotated every year. Which solution meets these requirements and is the MOST operationally efficient?
Question 403
A company is preparing to migrate its on-premises application to AWS. The application consists of application servers and a Microsoft SQL Server database The database cannot be migrated to a different engine because SQL Server features are used in the application's NET code. The company wants to attain the greatest availability possible while minimizing operational and management overhead. What should a solutions architect do to accomplish this?
Question 404
A company has an application running on Amazon EC2 instances in a private subnet. The application needs to store and retrieve data in Amazon S3. To reduce costs, the company wants to configure its AWS resources in a cost-effective manner. How should the company accomplish this?
Question 405
A media company has an application that tracks user clicks on its websites and performs analytics to provide near-real time recommendations. The application has a Heel of Amazon EC2 instances that receive data from the websites and send the data to an Amazon RDS DB instance. Another fleet of EC2 instances hosts the portion of the application that is continuously checking changes in the database and executing SQL queries to provide recommendations. Management has requested a redesign to decouple the infrastructure. The solution must ensure that data analysts are writing SQL to analyze the data only No data can the lost during the deployment. What should a solutions architect recommend?
Question 406
A company runs an application that uses multiple Amazon EC2 instances to gather data from its users. The data is then processed and transferred to Amazon S3 for long-term storage. A review of the application shows that there were long periods of time when the EC2 instances were not being used. A solutions architect needs to design a solution that optimizes utilization and reduces costs. Which solution meets these requirements?
Question 407
A company is using Site-to-Site VPN connections for secure connectivity to its AWS Cloud resources from on premises. Due to an increase in traffic across theVPN connections to the Amazon EC2 instances, users are experiencing slower VPN connectivity. Which solution will improve the VPN throughput?
Question 408
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. What should the solutions architect recommend to solve these issues?
Question 409
A company has several Amazon EC2 instances set up in a private subnet for security reasons. These instances host applications that read and write large amounts of data to and from Amazon S3 regularly. Currently, subnet routing directs all the traffic destined for the internet through a NAT gateway. The company wants to optimize the overall cost without impacting the ability of the application to communicate with Amazon S3 or the outside internet. What should a solutions architect do to optimize costs?
Question 410
A company is deploying an application in three AWS Regions using an Application Load Balancer Amazon Route 53 will be used to distribute traffic between theseRegions. Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?
