A company wants to host a global web application on AWS.It has the following design requirements:* The access pattern must allow for fetching data from multiple data sources.* Minimize the cost of API calls.* Keep page load times to within 50 ms.* Provide user authentication and authorization and manage data access for different user personas (for example, administrator, manager, or engineer).* Use a serverless design.Which set of strategies should a solutions architect use?Read More →

A company is developing a gene reporting device that will collect genomic information to assist researchers with collecting large samples of data from a diverse population.The device will push 8 KB of genomic data every second to a data platform that will need to process and analyze the data and provide information back to researchers.The data platform must meet the following requirements:• Provide near-real-time analytics of the inbound genomic data• Ensure the data is flexible, parallel, and durable• Deliver results of processing to a data warehouseWhich strategy should a solutions architect use to meet these requirements?Read More →

After your Lambda function has been running for some time, you need to look at some metrics to ascertain how your function is performing and decide to use theAWS CLI to do this.Which of the following commands must be used to access these metrics using the AWS CLI?Read More →

A company manufactures smart vehicles.The company uses a custom application to collect vehicle data.The vehicles use the MQTT protocol to connect to the application.The company processes the data in 5-minute intervals.The company then copies vehicle telematics data to on-premises storage.Custom applications analyze this data to detect anomalies.The number of vehicles that send data grows constantly.Newer vehicles generate high volumes of data.The on-premises storage solution is not able to scale for peak traffic, which results in data loss.The company must modernize the solution and migrate the solution to AWS to resolve the scaling challenges.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A large global company wants to migrate a stateless mission-critical application to AWS.The application is based on IBM WebSphere (application and integration middleware), IBM MQ (messaging middleware), and IBM DB2 (database software) on a z/OS operating system.How should the Solutions Architect migrate the application to AWS?Read More →

A large company runs workloads in VPCs that are deployed across hundreds of AWS accounts.Each VPC consists of public subnets and private subnets that span across multiple Availability Zones.NAT gateways are deployed in the public subnets and allow outbound connectivity to the internet from the private subnets.A solutions architect is working on a hub-and-spoke design.All private subnets in the spoke VPCs must route traffic to the internet through an egress VPC.The solutions architect already has deployed a NAT gateway in an egress VPC in a central AWS account.Which set of additional steps should the solutions architect take to meet these requirements?Read More →

A company is planning the migration of several lab environments used for software testing.An assortment of custom tooling is used to manage the test runs for each lab.The labs use immutable infrastructure for the software test runs, and the results are stored in a highly available SQL database cluster.Although completely rewriting the custom tooling is out of scope for the migration project, the company would like to optimize workloads during the migration.Which application migration strategy meets this requirement?Read More →

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.Which combination of steps will meet these requirements?
