A company has an application with a REST-based interface that allows data to be received in near-real time from a third-party vendor.Once received, the application processes and stores the data for further analysis.The application is running on Amazon EC2 instances.The third-party vendor has received many 503 Service Unavailable Errors when sending data to the application.When the data volume spikes, the compute capacity reaches its maximum limit and the application is unable to process all requests.Which design should a solutions architect recommend to provide a more scalable solution?Read More →

A company recently deployed a two-tier application in two Availability Zones in the us-east-1 Region.The databases are deployed in a private subnet while the web servers are deployed in a public subnet.An internet gateway is attached to the VPC.The application and database run on Amazon EC2 instances.The database servers are unable to access patches on the internet.A solutions architect needs to design a solution that maintains database security with the least operational overhead.Which solution meets these requirements?Read More →

A company has global users accessing an application deployed in different AWS Regions, exposing public static IP addresses.The users are experiencing poor performance when accessing the application over the internet.What should a solutions architect recommend to reduce internet latency?Read More →

A solutions architect must design a solution for a persistent database that is being migrated from on-premises to AWS.The database requires 64,000 IOPS according to the database administrator.If possible, the database administrator wants to use a single Amazon Elastic Block Store (Amazon EBS) volume to host the database instance.Which solution effectively meets the database administrator’s criteria?Read More →

A three-tier web application processes orders from customers.The web tier consists of Amazon EC2 instances behind an Application Load Balancer, a middle tier of three EC2 instances decoupled from the web tier using Amazon SQS, and an Amazon DynamoDB backend.At peak times, customers who submit orders using the site have to wait much longer than normal to receive confirmations due to lengthy processing times.A solutions architect needs to reduce these processing times.Which action will be MOST effective in accomplishing this?Read More →

A solutions architect must create a highly available bastion host architecture.The solution needs to be resilient within a single AWS Region and should require only minimal effort to maintain.What should the solutions architect do to meet these requirements?Read More →

A web application runs on Amazon EC2 instances behind an Application Load Balancer.The application allows users to create custom reports of historical weather data.Generating a report can take up to 5 minutes.These long-running requests use many of the available incoming connections, making the system unresponsive to other users.How can a solutions architect make the system more responsive?Read More →

An application is running on Amazon EC2 instances.Sensitive information required for the application is stored in an Amazon S3 bucket.The bucket needs to be protected from internet access while only allowing services within the VPC access to the bucket.Which combination of actions should solutions archived take to accomplish this? (Choose two.)Read More →

A company uses Amazon S3 as its object storage solution.The company has thousands of S3 buckets it uses to store data.Some of the S3 buckets have data that is accessed less frequently than others.A solutions architect found that lifecycle policies are not consistently implemented or are implemented partially, resulting in data being stored in high-cost storage.Which solution will lower costs without compromising the availability of objects?Read More →

A company has users all around the world accessing its HTTP-based application deployed on Amazon EC2 instances in multiple AWS Regions.The company wants to improve the availability and performance of the application.The company also wants to protect the application against common web exploits that may affect availability, compromise security, or consume excessive resources.Static IP addresses are required.What should a solutions architect recommend to accomplish this?Read More →
