Solutions Architect Professional (Page 37)

A software company has deployed an application that consumes a REST API by using Amazon API Gateway, AWS Lambda functions, and an Amazon DynamoDB table.The application is showing an increase in the number of errors during PUT requests.Most of the PUT calls come from a small number of clients that are authenticated with specific API keys.A solutions architect has identified that a large number of the PUT requests originate from one client.The API is noncritical, and clients can tolerate retries of unsuccessful calls.However, the errors are displayed to customers and are causing damage to the API’s reputation.What should the solutions architect recommend to improve the customer experience?Read More →

A company maintains a restaurant review website.The website is a single-page application where files are stored in Amazon S3 and delivered using AmazonCloudFront.The company receives several fake postings every day that are manually removed.The security team has identified that most of the fake posts are from bots with IP addresses that have a bad reputation within the same global region.The team needs to create a solution to help restrict the bots from accessing the website.Which strategy should a solutions architect use?Read More →

A company is running a data-intensive application on AWS.The application runs on a cluster of hundreds of Amazon EC2 instances.A shared file system also runs on several EC2 instances that store 200 TB of data.The application reads and modifies the data on the shared file system and generates a report.The job runs once monthly, reads a subset of the files from the shared file system, and takes about 72 hours to complete.The compute instances scale in an Auto Scaling group, but the instances that host the shared file system run continuously.The compute and storage instances are all in the same AWS Region.A solutions architect needs to reduce costs by replacing the shared file system instances.The file system must provide high performance access to the needed data for the duration of the 72-hour run.Which solution will provide the LARGEST overall cost reduction while meeting these requirements?Read More →

A company is serving files to its customer through an SFTP server that is accessible over the Internet.The SFTP server is running on a single Amazon EC2 instance with an Elastic IP address attached.Customers connect to the SFTP server through its Elastic IP address and use SSH for authentication.The EC2 instance also has an attached security group that allows access from all customer IP addresses.A solutions architect must implement a solution to improve availability, minimize the complexity of infrastructure management, and minimize the disruption to customers who access files.The solution must not change the way customers connect.Which solution will meet these requirements?Read More →

A company plans to migrate a legacy on-premises application to AWS.The application is a Java web application that runs on Apache Tomcat with a PostgreSQL database.The company does not have access to the source code but can deploy the application Java Archive (JAR) files.The application has increased traffic at the end of each month.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A solutions architect at a large company needs to set up network security for outbound traffic to the internet from all AWS accounts within an organization in AWSOrganizations.The organization has more than 100 AWS accounts, and the accounts route to each other by using a centralized AWS Transit Gateway.Each account has both an internet gateway and a NAT gateway for outbound traffic to the internet.The company deploys resources only into a single AWS Region.The company needs the ability to add centrally managed rule-based filtering on all outbound traffic to the internet for all AWS accounts in the organization.The peak load of outbound traffic will not exceed 25 Gbps in each Availability Zone.Which solution meets these requirements?Read More →

A live-events company is designing a scaling solution for its ticket application on AWS.The application has high peaks of utilization during sale events.Each sale event is a one-time event that is scheduled.The application runs on Amazon EC2 instances that are in an Auto Scaling group.The application uses PostgreSQL for the database layer.The company needs a scaling solution to maximize availability during the sale events.Which solution will meet these requirements?Read More →

A company wants to migrate its data analytics environment from on premises to AWS.The environment consists of two simple Node.js applications.One of the applications collects sensor data and loads it into a MySQL database.The other application aggregates the data into reports.When the aggregation jobs run, some of the load jobs fail to run correctly.The company must resolve the data loading issue.The company also needs the migration to occur without interruptions or changes for the company’s customers.What should a solutions architect do to meet these requirements?Read More →

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’s underlying data storage to AWS.The application data is stored on a shared file 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 to its new location while still allowing the on-premises application to access the data.Which solution will meet these requirements?Read More →

A company runs an application that gives users the ability to search for videos and related information by using keywords that are curated from content providers.The application data is stored in an on-premises Oracle database that is 800 GB in size.The company wants to migrate the data to an Amazon Aurora MySQL DB instance.A solutions architect plans to use the AWS Schema Conversion Tool andAWS Database Migration Service (AWS DMS) for the migration.During the migration, the existing database must serve ongoing requests.The migration must be completed with minimum downtime.Which solution will meet these requirements?Read More →
