A company runs an ordering system on AWS using Amazon SQS and AWS Lambda, with each order received as a JSON message.Recently the company had a marketing event that led to a tenfold increase in orders.With this increase, the following undesired behaviors started in the ordering system:✑ Lambda failures while processing orders lead to queue backlogs.✑ The same orders have been processed multiple times.A Solutions Architect has been asked to solve the existing issues with the ordering system and add the following resiliency features:✑ Retain problematic orders for analysis.✑ Send notification if errors go beyond a threshold value.How should the Solutions Architect meet these requirements?Read More →

A company has a data center that must be migrated to AWS as quickly as possible.The data center has a 500 Mbps AWS Direct Connect link and a separate, fully available 1 Gbps ISP connection.A Solutions Architect must transfer 20 TB of data from the data center to an Amazon S3 bucket.What is the FASTEST way transfer the data?Read More →

A company runs a memory-intensive analytics application using on-demand Amazon EC2 C5 compute optimized instance.The application is used continuously and application demand doubles during working hours.The application currently scales based on CPU usage.When scaling in occurs, a lifecycle hook is used because the instance requires 4 minutes to clean the application state before terminating.Because users reported poor performance during working hours, scheduled scaling actions were implemented so additional instances would be added during working hours.The Solutions Architect has been asked to reduce the cost of the application.Which solution is MOST cost-effective?Read More →

A Solutions Architect needs to migrate a legacy application from on premises to AWS.On premises, the application runs on two Linux servers behind a load balancer and accesses a database that is master-master on two servers.Each application server requires a license file that is tied to the MAC address of the server’s network adapter.It takes the software vendor 12 hours to send ne license files through email.The application requires configuration files to use static.IPv4 addresses to access the database servers, not DNS.Given these requirements, which steps should be taken together to enable a scalable architecture for the application servers? (Choose two.)Read More →

A company has a 24 TB MySQL database in its on-premises data center that grows at the rate of 10 GB per day.The data center is connected to the company’sAWS infrastructure with a 50 Mbps VPN connection.The company is migrating the application and workload to AWS.The application code is already installed and tested on Amazon EC2.The company now needs to migrate the database and wants to go live on AWS within 3 weeks.Which of the following approaches meets the schedule with LEAST downtime?Read More →

A company is creating an account strategy so that they can begin using AWS.The Security team will provide each team with the permissions they need to follow the principle or least privileged access.Teams would like to keep their resources isolated from other groups, and the Finance team would like each team’s resource usage separated for billing purposes.Which account creation process meets these requirements and allows for changes?Read More →

A company wants to analyze log data using date ranges with a custom application running on AWS.The application generates about 10 GB of data every day, which is expected to grow.A Solutions Architect is tasked with storing the data in Amazon S3 and using Amazon Athena to analyze the data.Which combination of steps will ensure optimal performance as the data grows? (Choose two.)Read More →

While debugging a backend application for an IoT system that supports globally distributed devices, a Solutions Architect notices that stale data is occasionally being sent to user devices.Devices often share data, and stale data does not cause issues in most cases.However, device operations are disrupted when a device reads the stale data after an update.The global system has multiple identical application stacks deployed in different AWS Regions.If a user device travels out of its home geographic region, it will always connect to the geographically closest AWS Region to write or read data.The same data is available in all supported AWS Regions using an AmazonDynamoDB global table.What change should be made to avoid causing disruptions in device operations?Read More →

A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs. The company needs to increase visibility into details of AWS Billing and Cost Management. There are various accounts associated with AWS Organizations, including many development and production accounts. There is no consistent tagging strategy across the organization, but there are guidelines in place that require all infrastructure to be deployed usingAWS CloudFormation with consistent tagging. Management requires cost center numbers and project ID numbers for all existing and future DynamoDB tables andRDS instances.Which strategy should the solutions architect provide to meet these requirements?Read More →

A company provides a centralized Amazon EC2 application hosted in a single shared VPC.The centralized application must be accessible from client applications running in the VPCs of other business units.The centralized application front end is configured with a Network Load Balancer (NLB) for scalability.Up to 10 business unit VPCs will need to be connected to the shared VPC.Some of the business unit VPC CIDR blocks overlap with the shared VPC, and some overlap with each other.Network connectivity to the centralized application in the shared VPC should be allowed from authorized business unit VPCs only.Which network configuration should a solutions architect use to provide connectivity from the client applications in the business unit VPCs to the centralized application in the shared VPC?Read More →
