A company's web application has reliability issues. The application serves customers globally. The application runs on a single Amazon EC2 instance and performs read-intensive operations on an Amazon RDS for MySQL database. During high load, the application becomes unresponsive and requires a manual restart of the EC2 instance. A solutions architect must improve the application's reliability. Which solution will meet this requirement with the LEAST development effort?

A company needs to use an AWS Transfer Family SFTP-enabled server with an Amazon S3 bucket to receive updates from a third-party data supplier. The data is encrypted with Pretty Good Privacy (PGP) encryption. The company needs a solution that will automatically decrypt the data after the company receives the data. A solutions architect will use a Transfer Family managed workflow. The company has created an IAM service role by using an IAM policy that allows access to AWS Secrets Manager and the S3 bucket. The role’s trust relationship allows the transfer amazonaws.com service to assume the role. What should the solutions architect do next to complete the solution for automatic decryption?

A company is migrating infrastructure for its massive multiplayer game to AWS. The game’s application features a leaderboard where players can see rankings in real time. The leaderboard requires microsecond reads and single-digit-millisecond write latencies. The datasets are single-digit terabytes in size and must be available to accept writes in less than a minute if a primary node failure occurs. The company needs a solution in which data can persist for further analytical processing through a data pipeline. Which solution will meet these requirements with the LEAST operational overhead?

A company is running several applications in the AWS Cloud. The applications are specific to separate business units in the company. The company is running the components of the applications in several AWS accounts that are in an organization in AWS Organizations. Every cloud resource in the company’s organization has a tag that is named BusinessUnit. Every tag already has the appropriate value of the business unit name. The company needs to allocate its cloud costs to different business units. The company also needs to visualize the cloud costs for each business unit. Which solution will meet these requirements?

A utility company wants to collect usage data every 5 minutes from its smart meters to facilitate time-of-use metering. When a meter sends data to AWS, the data is sent to Amazon API Gateway, processed by an AWS Lambda function. and stored in an Amazon DynamoDB table. During the pilot phase, the Lambda functions took from 3 to 5 seconds to complete. As more smart meters are deployed, the engineers notice the Lambda functions are taking from 1 to 2 minutes to complete. The functions are also increasing in duration as new types of metrics are collected from the devices. There are many ProvisionedThroughputExceededException errors while performing PUT operations on DynamoDB, and there are also many TooManyRequestsException errors from Lambda. Which combination of changes will resolve these issues? (Choose two.)

A company recently completed a successful proof of concept of Amazon WorkSpaces. A solutions architect needs to make the solution highly available across two AWS Regions. Amazon WorkSpaces is deployed in a failover Region, and a hosted zone is deployed in Amazon Route 53. What should the solutions architect do to configure high availability for the solution?

A company plans to migrate many VMs from an on-premises environment to AWS. The company requires an initial assessment of the on-premises environment before the migration, a visualization of the dependencies between applications that run on the VMs, and a report that provides an assessment of the on-premises environment. To get this information, the company has initiated a Migration Evaluator assessment request. The company has the ability to install collector software in its on-premises environment without any constraints Which solution will provide the company with the required information with the LEAST operational overhead?

A company hosts its primary API on AWS by using an Amazon API Gateway API and AWS Lambda functions that contain the logic for the API methods. The company’s internal applications use the API for core functionality and business logic. The company’s customers use the API to access data from their accounts. Several customers also have access to a legacy API that is running on a single standalone Amazon EC2 instance. The company wants to increase the security for these APIs to better prevent denial of service (DoS) attacks, check for vulnerabilities, and guard against common exploits. What should a solutions architect do to meet these requirements?

A company is running a serverless ecommerce application on AWS. The application uses Amazon API Gateway to invoke AWS Lambda Java functions. The Lambda functions connect to an Amazon RDS for MySQL database to store data. During a recent sale event, a sudden increase in web traffic resulted in poor API performance and database connection failures. The company needs to implement a solution to minimize the latency for the Lambda functions and to support bursts in traffic. Which solution will meet these requirements with the LEAST amount of change to the application?

A company requires that all internal application connectivity use private IP addresses. To facilitate this policy, a solutions architect has created interface endpoints to connect to AWS Public services. Upon testing, the solutions architect notices that the service names are resolving to public IP addresses, and that internal services cannot connect to the interface endpoints. Which step should the solutions architect take to resolve this issue?

A company is developing a latency-sensitive application. Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible. The Lambda functions are written in Java and contain initialization code outside the handlers to load libraries, initialize classes, and generate unique IDs. Which solution will meet the startup performance requirement MOST cost-effectively?

A solutions architect is importing a VM from an on-premises environment by using the Amazon EC2 VM Import feature of AWS Import/Export. The solutions architect has created an AMI and has provisioned an Amazon EC2 instance that is based on that AMI. The EC2 instance runs inside a public subnet in a VPC and has a public IP address assigned. The EC2 instance does not appear as a managed instance in the AWS Systems Manager console. Which combination of steps should the solutions architect take to troubleshoot this issue? (Choose two.)

A company is using AWS CloudFormation as its deployment tool for all applications. It stages all application binaries and templates within Amazon S3 buckets with versioning enabled. Developers have access to an Amazon EC2 instance that hosts the integrated development environment (IDE). The developers download the application binaries from Amazon S3 to the EC2 instance, make changes, and upload the binaries to an S3 bucket after running the unit tests locally. The developers want to improve the existing deployment mechanism and implement CI/CD using AWS CodePipeline. The developers have the following requirements: • Use AWS CodeCommit for source control. • Automate unit testing and security scanning. • Alert the developers when unit tests fail. • Turn application features on and off, and customize deployment dynamically as part of CI/CD. • Have the lead developer provide approval before deploying an application. Which solution will meet these requirements?

A global ecommerce company has many data centers around the world. With the growth of its stored data, the company needs to set up a solution to provide scalable storage for legacy on-premises file applications. The company must be able to take point-in-time copies of volumes by using AWS Backup and must retain low-latency access to frequently accessed data. The company also needs to have storage volumes that can be mounted as Internet Small Computer System Interface (iSCSI) devices from the company’s on-premises application servers. Which solution will meet these requirements?

A company has an application that uses AWS Key Management Service (AWS KMS) to encrypt and decrypt data. The application stores data in an Amazon S3 bucket in an AWS Region. Company security policies require the data to be encrypted before the data is placed into the S3 bucket. The application must decrypt the data when the application reads files from the S3 bucket. The company replicates the S3 bucket to other Regions. A solutions architect must design a solution so that the application can encrypt and decrypt data across Regions. The application must use the same key to decrypt the data in each Region. Which solution will meet these requirements?

A company hosts an application that uses several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). During the initial startup of the EC2 instances, the EC2 instances run user data scripts to download critical content for the application from an Amazon S3 bucket. The EC2 instances are launching correctly. However, after a period of time, the EC2 instances are terminated with the following error message: “An instance was taken out of service in response to an ELB system health check failure.” EC2 instances continue to launch and be terminated because of Auto Scaling events in an endless loop. The only recent change to the deployment is that the company added a large amount of critical content to the S3 bucket. The company does not want to alter the user data scripts in production. What should a solutions architect do so that the production environment can deploy successfully?

A company needs to move some on-premises Oracle databases to AWS. The company has chosen to keep some of the databases on premises for business compliance reasons. The on-premises databases contain spatial data and run cron jobs for maintenance. The company needs to connect to the on-premises systems directly from AWS to query data as a foreign table. Which solution will meet these requirements?

Accompany runs an application on Amazon EC2 and AWS Lambda. The application stores temporary data in Amazon S3. The S3 objects are deleted after 24 hours. The company deploys new versions of the application by launching AWS CloudFormation stacks. The stacks create the required resources. After validating a new version, the company deletes the old stack. The deletion of an old development stack recently failed. A solutions architect needs to resolve this issue without major architecture changes. Which solution will meet these requirements?

A company has an application that stores user-uploaded videos in an Amazon S3 bucket that uses S3 Standard storage. Users access the videos frequently in the first 180 days after the videos are uploaded. Access after 180 days is rare. Named users and anonymous users access the videos. Most of the videos are more than 100 MB in size. Users often have poor internet connectivity when they upload videos, resulting in failed uploads. The company uses multipart uploads for the videos. A solutions architect needs to optimize the S3 costs of the application. Which combination of actions will meet these requirements? (Choose two.)

A company runs an ecommerce web application on AWS. The web application is hosted as a static website on Amazon S3 with Amazon CloudFront for content delivery. An Amazon API Gateway API invokes AWS Lambda functions to handle user requests and order processing for the web application The Lambda functions store data in an Amazon ROS for MySQL DB cluster that uses On-Demand instances. The DB cluster usage has been consistent in the past 12 months. Recently, the website has experienced SQL injection and web exploit attempts. Customers also report that order processing time has increased during periods of peak usage. During these periods, the Lambda functions often have cold starts. As the company grows, the company needs to ensure scalability and low-latency access during traffic peaks. The company also must optimize the database costs and add protection against the SQL injection and web exploit attempts. Which solution will meet these requirements?
