Solutions Architect Professional (Page 91)

A solutions architect needs to review the design of an Amazon EMR cluster that is using the EMR File System (EMRFS).The cluster performs tasks that are critical to business needs.The cluster is running Amazon EC2 On-Demand Instances at all times for all task, master, and core nodes.The EMR tasks run each morning, starting at 1:00 AM.and take 6 hours to finish running.The amount of time to complete the processing is not a priority because the data is not referenced until late in the day.The solutions architect must review the architecture and suggest a solution to minimize the compute costs.Which solution should the solutions architect recommend to meet these requirements?Read More →

A company is running a critical application that uses an Amazon RDS for MySQL database to store data.The RDS DB instance is deployed in Multi-AZ mode.A recent RDS database failover test caused a 40-second outage to the application.A solutions architect needs to design a solution to reduce the outage time to less than 20 seconds.Which combination of steps should the solutions architect take to meet these requirements?

A company is using Amazon API Gateway to deploy a private REST API that will provide access to sensitive data.The API must be accessible only from an application that is deployed in a VPC.The company deploys the API successfully.However, the API is not accessible from an Amazon EC2 instance that is deployed in the VPC.Which solution will provide connectivity between the EC2 instance and the API?Read More →

A solutions architect works for a government agency that has strict disaster recovery requirements.All Amazon Elastic Block Store (Amazon EBS) snapshots are required to be saved in at least two additional AWS Regions.The agency also is required to maintain the lowest possible operational overhead.Which solution meets these requirements?Read More →

A company is running a custom database in the AWS Cloud.The database uses Amazon EC2 for compute and uses Amazon Elastic Block Store (Amazon EBS) for storage.The database runs on the latest generation of EC2 instances and uses a General Purpose SSD (gp2) EBS volume for data.The current data volume has the following characteristics:✑ The volume is 512 GB in size.✑ The volume never goes above 256 GB utilization.✑ The volume consistently uses around 1,500 IOPS.A solutions architect needs to conduct an analysis of the current database storage layer and make a recommendation about ways to reduce cost.Which solution will provide the MOST cost savings without impacting the performance of the database?Read More →

An environmental company is deploying sensors in major cities throughout a country to measure air quality.The sensors connect to AWS IoT Core to ingest timeseries data readings.The company stores the data in Amazon DynamoDB.For business continuity, the company must have the ability to ingest and store data in two AWS Regions.Which solution will meet these requirements?Read More →

A company has more than 10,000 sensors that send data to an on-premises Apache Kafka server by using the Message Queuing Telemetry Transport (MQTT) protocol.The on-premises Kafka server transforms the data and then stores the results as objects in an Amazon S3 bucket.Recently, the Kafka server crashed.The company lost sensor data while the server was being restored.A solutions architect must create a new design on AWS that is highly available and scalable to prevent a similar occurrence.Which solution will meet these requirements?Read More →

A company needs to use an AWS Transfer Family SFTP-enabled server with an Amazon S3 bucket to receive updates from a third-party data supplier.The data is encrypted with Pretty Good Privacy (PGP) encryption.The company needs a solution that will automatically decrypt the data after the company receives the data.A solutions architect will use a Transfer Family managed workflow.The company has created an IAM service role by using an IAM policy that allows access to AWS Secrets Manager and the S3 bucket.The role’s trust relationship allows the transfer amazonaws.com service to assume the role.What should the solutions architect do next to complete the solution for automatic decryption?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 throughSMB.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 toAWS 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 is deploying a third-party firewall appliance solution from AWS Marketplace to monitor and protect traffic that leaves the company’s AWS environments.The company wants to deploy this appliance into a shared services VPC and route all outbound internet-bound traffic through the appliances.A solutions architect needs to recommend a deployment method that prioritizes reliability and minimizes failover time between firewall appliances within a single AWS Region.The company has set up routing from the shared services VPC to other VPCs.Which steps should the solutions architect recommend to meet these requirements?
