A company has a web application that uses Amazon API Gateway. AWS Lambda and Amazon DynamoDB A recent marketing campaign has increased demand Monitoring software reports that many requests have significantly longer response times than before the marketing campaign
A solutions architect enabled Amazon CloudWatch Logs for API Gateway and noticed that errors are occurring on 20% of the requests. In CloudWatch. the Lambda function. Throttles metric represents 1% of the requests and the Errors metric represents 10% of the requests Application logs indicate that, when errors occur there is a call to DynamoDB
What change should the solutions architect make to improve the current response times as the web application becomes more popular'?
A company wants to send data from its on-premises systems to Amazon S3 buckets. The company created the S3 buckets in three different accounts. The company must send the data privately without the data traveling across the internet The company has no existing dedicated connectivity to AWS
Which combination of steps should a solutions architect take to meet these requirements? (Select TWO.)
A company hosts a data-processing application on Amazon EC2 instances. The application polls an Amazon Elastic File System (Amazon EFS) file system for newly uploaded files. When a new file is detected, the application extracts data from the file and runs logic to select a Docker container image to process the file. The application starts the appropriate container image and passes the file location as a parameter.
The data processing that the container performs can take up to 2 hours. When the processing is complete, the code that runs inside the container writes the file back to Amazon EFS and exits.
The company needs to refactor the application to eliminate the EC2 instances that are running the containers

A company has implemented a new security requirement According to the new requirement, the company must scan all traffic from corporate AWS instances in the company's VPC for violations of the company's security policies. As a result of these scans the company can block access to and from specific IP addresses.
To meet the new requirement, the company deploys a set of Amazon EC2 instances in private subnets to serve as transparent proxies The company installs approved proxy server software on these EC2 instances The company modifies the route tables on all subnets to use the corresponding EC2 instances with proxy software as the default route The company also creates security groupsthat are compliant with the security policies and assigns these security groups to the EC2 instances
Despite these configurations, the traffic of the EC2 instances in their private subnets is not being properly forwarded to the internet.
What should a solutions architect do to resolve this issue?
A company has an application that analyzes and stores image data on premises The application receives millions of new image files every day Files are an average of 1 MB in size The files are analyzed in batches of 1 GB When the application analyzes a batch the application zips the imagestogether The application then archives the images as a single file in an on-premises NFS server for long-term storage
The company has a Microsoft Hyper-V environment on premises and has compute capacity available The company does not have storage capacity and wants to archive the images on AWS The company needs the ability to retrieve archived data within t week of a request.
The company has a 10 Gbps AWS Direct Connect connection between its on-premises data center and AWS. The company needs to set bandwidth limits and schedule archived images to be copied to AWS dunng non-business hours.
Which solution will meet these requirements MOST cost-effectively?
A global company has a mobile app that displays ticket barcodes. Customers use the tickets on the mobile app to attend live events. Event scanners read the ticket barcodes and call a backend API to validate the barcode data against data in a database. After the barcode is scanned, the backend logic writes to the database's single table to mark the barcode as used. The company needs to deploy the app on AWS with a DNS name of api.example.com. The company will host the database in three AWS Regions around the world. Which solution will meet these requirements with the LOWEST latency?
A company has migrated its forms-processing application to AWS. When users interact with the application, they upload scanned forms as files through a web application. A database stores user metadata and references to files that are stored in Amazon S3. The web application runs on Amazon EC2 instances and an Amazon RDS for PostgreSQL database.
When forms are uploaded, the application sends notifications to a team through Amazon Simple Notification Service (Amazon SNS). A team member then logs in and processes each form. The team member performs data validation on the form and extracts relevant data before entering the information into another system that uses an API.
A solutions architect needs to automate the manual processing of the forms. The solution must provide accurate form extraction, minimize time to market, and minimize long-term operational overhead.

A company wants to migrate an application to Amazon EC2 from VMware Infrastructure that runs in an on-premises data center. A solutions architect must preserve the software and configuration settings during the migration.
What should the solutions architect do to meet these requirements?
Question:
A company mandates that all internal AWS communications useprivate IPs. A solutions architect createdinterface VPC endpointsfor public AWS services like S3. However, service names are still resolving topublic IP addresses, and the internal apps cannot connect.

A company completed a successful Amazon Workspaces proof of concept. They now want to make Workspaceshighly available across two AWS Regions. Workspaces are deployed in the failover Region. A hosted zone is available in Amazon Route 53.
What should the solutions architect do?
A company has migrated an application from on premises to AWS. The application frontend is a static website that runs on two Amazon EC2 instances behind an Application Load Balancer (ALB). The application backend is a Python application that runs on three EC2 instances behind another ALB. The EC2 instances are large, general purpose On-Demand Instances that were sized to meet the on-premises specifications for peak usage of the application.
The application averages hundreds of thousands of requests each month. However, the application is used mainly during lunchtime and receives minimal traffic during the rest of the day.
A solutions architect needs to optimize the infrastructure cost of the application without negatively affecting the application availability.

A company needs to migrate a 2 TB MySQL database from an on-premises data center to an Amazon Aurora cluster. The database receives hundreds of updates every minute. The on-premises database server is not accessible through the internet.
The migration solution must ensure that no data is lost between the start of migration and cutover. The migration must begin as soon as possible and must minimize downtime.

A company is collecting a large amount of data from a fleet of loT devices Data is stored as Optimized Row Columnar (ORC) files in the Hadoop Distributed File System (HDFS) on a persistent Amazon EMR cluster. The company's data analytics team queries the data by using SQL in Apache Presto deployed on the same EMR cluster Queries scan large amounts of data, always run for less than 15 minutes, and run only between 5 PM and 10 PM.
The company is concerned about the high cost associated with the current solution A solutions architect must propose the most cost-effective solution that will allow SQL data queries
Which solution will meet these requirements?
A company is using AWS CodePipeline for the CI/CD of an application to an Amazon EC2 Auto Scaling group. All AWS resources are defined in AWS
CloudFormation templates. The application artifacts are stored in an Amazon S3 bucket and deployed to the Auto Scaling group using instance user data scripts.
As the application has become more complex, recent resource changes in the CloudFormation templates have caused unplanned downtime.
How should a solutions architect improve the CI/CD pipeline to reduce the likelihood that changes in the templates will cause downtime?
A solutions architect has created a single VPC on AWS. The VPC has one internet gateway and one NAT gateway. The VPC extends across three Availability Zones. Each Availability Zone includes one public subnet and one private subnet. The three private subnets contain Amazon EC2 instances that must be able to connect to the internet.
Which solution will increase the network resiliency of this architecture?
