A company has developed a mobile game. The backend for the game runs on several virtual machines located in an on-premises data center. The business logic is exposed using a REST API with multiple functions. Player session data is stored in central file storage. Backend services use different API keys for throttling and to distinguish between live and test traffic.
The load on the game backend varies throughout the day. During peak hours, the server capacity is not sufficient. There are also latency issues when fetching player session data. Management has asked a solutions architect to present a cloud architecture that can handle the game ' s varying load and provide low-latency data access. The API model should not be changed.

A company operates an on-premises software-as-a-service (SaaS) solution that ingests several files daily. The company provides multiple public SFTP endpoints to its customers to facilitate the file transfers. The customers add the SFTP endpoint IP addresses to their firewall allow list for outbound traffic. Changes to the SFTP endmost IP addresses are not permitted.
The company wants to migrate the SaaS solution to AWS and decrease the operational overhead of the file transfer service.

A company is designing its network configuration in the AWS Cloud. The company uses AWS Organizations to manage a multi-account setup. The company has three OUs. Each OU contains more than 100 AWS accounts. Each account has a single VPC, and all the VPCs in each OU are in the same AWS Region.
The CIDR ranges for all the AWS accounts do not overlap. The company needs to implement a solution in which VPCs in the same OU can communicate with each other but cannot communicatewith VPCs in other OUs.
Which solution will meet these requirements with the LEAST operational overhead?
A financial services company loaded millions of historical stock trades into an Amazon DynamoDB table. The table uses on-demand capacity mode. Once each day at midnight, a few million new records are loaded into the table. Application read activity against the table happens in bursts throughout the day. and a limited set of keys are repeatedly looked up. The company needs to reduce costs associated with DynamoDB.
Which strategy should a solutions architect recommend to meet this requirement?
A machine learning (ML) company continuously develops new versions of its models. The models are integrated into a web application that uses a RESTful API to call custom Python code to invoke the models. The application runs in an Amazon EC2 Auto Scaling group.
Customer feedback indicates that new model versions sometimes perform worse than previous versions. The company wants to implement a gradual deployment approach in which 10% of traffic is initially routed to new models to verify performance. The solution must also reduce operational overhead for infrastructure management.
Which solution will meet these requirements with the LEAST operational overhead?
A company is developing a serverless application that runs in a VPC. The VPC has public and private IPv4 subnets across multiple Availability Zones. The application connects to the internet through multiple public NAT gateways and an internet gateway.
The company must integrate the application with a new service from an external provider by using an AWS Lambda function. The external provider accepts requests from only public IPv4 addresses that are on an approved list. The company must provide connectivity details to the external provider before the application can start using the new service.
Which solution will give the application the ability to access the new service?
A company has a legacy application that runs on multiple .NET Framework components. The components share the same Microsoft SQL Server database and
communicate with each other asynchronously by using Microsoft Message Queueing (MSMQ).
The company is starting a migration to containerized .NET Core components and wants to refactor the application to run on AWS. The .NET Core components require complex orchestration. The company must have full control over networking and host configuration. The application ' s database model is strongly relational.
Which solution will meet these requirements?
A company is using multiple AWS accounts The DNS records are stored in a private hosted zone for Amazon Route 53 in Account A The company ' s applications and databases are running in Account B.
A solutions architect win deploy a two-net application In a new VPC To simplify the configuration, the db.example com CNAME record set tor the Amazon RDS endpoint was created in a private hosted zone for Amazon Route 53.
During deployment, the application failed to start. Troubleshooting revealed that db.example com is not resolvable on the Amazon EC2 instance The solutions architect confirmed that the record set was created correctly in Route 53.
Which combination of steps should the solutions architect take to resolve this issue? (Select TWO )
A company is hosting an application on AWS for a project that will run for the next 3 years. The application consists of 20 Amazon EC2 On-Demand Instances that are registered in a target group for a Network Load Balancer (NLB). The instances are spread across two Availability Zones. The application is stateless and runs 24 hours a day, 7 days a week.
The company receives reports from users who are experiencing slow responses from the application. Performance metrics show that the instances are at 10% CPU utilization during normal application use. However, the CPU utilization increases to 100% at busy times, which typically last for a few hours.
The company needs a new architecture to resolve the problem of slow responses from the application.
Which solution will meet these requirements MOST cost-effectively?
A company is developing and hosting several projects in the AWS Cloud. The projects are developed across multiple AWS accounts under the same organization in AWS Organizations. The company requires the cost lor cloud infrastructure to be allocated to the owning project. The team responsible for all of the AWS accounts has discovered that several Amazon EC2 instances are lacking the Project tag used for cost allocation.
Which actions should a solutions architect take to resolve the problem and prevent it from happening in the future? (Select THREE.)
A company is developing a new on-demand video application that is based on microservices. The application will have 5 million users at launch and will have 30 million users after 6 months. The company has deployed the application on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate. The company developed the application by using ECS services that use the HTTPS protocol.
A solutions architect needs to implement updates to the application by using blue/green deployments. The solution must distribute traffic to each ECS service through a load balancer. The application must automatically adjust the number of tasks in response to an Amazon CloudWatch alarm.
Which solution will meet these requirements?
A company has an IoT data lake that is stored in Amazon S3. Data scientists in a separate AWS account need to analyze the data on Amazon EC2 instances in a VPC. Company policy requires that only authorized networks access the IoT data. The EC2 instances already have an IAM role that allows access to Amazon S3. An S3 access point exists on the data lake S3 bucket.
The company needs to provide secure access to the S3 data lake for the EC2 instances while complying with the policy that requires access from only authorized networks.
Which combination of steps will meet these requirements? (Select TWO.)
A company wants to back up its on-premises intranet application to the AWS Cloud. The company wants to use AWS Elastic Disaster Recovery for the backup solution.
The company requires that replication traffic must travel across a private dedicated connection. The application must not be accessible from the public internet. The solution cannot consume more than 75% of the available bandwidth between the on-premises network and AWS.
Which combination of steps will meet these requirements? (Select THREE.)
A company has 20 accounts in an organization in AWS Organizations. The accounts are in two OUs: development and production. Multiple teams use the development accounts.
The company wants to control the cost that is associated with the development accounts. The company needs a solution that provides a notification when the forecasted monthly cost for all development accounts exceeds a threshold.
A solutions architect creates an Amazon SNS topic and subscribes an email address to the topic.
What should the solutions architect do next to meet the notification requirement with the LEAST configuration effort?
A company is planning to migrate an application from on premises to the AWS Cloud The company will begin the migration by moving the application underlying data storage to AWS The application data is stored on a shared tile system on premises and the application servers connect to the shared file system through SMB
A solutions architect must implement a solution that uses an Amazon S3 bucket for shared storage. Until the application is fully migrated and code is rewritten to use native Amazon S3 APIs the application must continue to have access to the data through SMB The solutions architect must migrate the application data to AWS (o its new location while still allowing the on-premises application to access the data
