Amazon (SAP-C01) Exam Questions And Answers page 13

A company is developing a gene reporting device that will collect genomic information to assist researchers will 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 warehouse

Which strategy should a solutions architect use to meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company is developing a messaging application that is based on a microservices architecture. A separate team develops each microservice by using Amazon Elastic Container Service (Amazon ECS). The teams deploy the microservices multiple times daily by using AWS CloudFormation and AWS CodePipeline.

The application recently grew in size and complexity. Each service operates correctly on its own during development, but each service produces error messages when it has to interact with other services in production. A solutions architect must improve the application s availability.

Which solution will meet these requirements with the LEAST amount of operational overhead?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company is developing a new service that will be accessed using TCP on a static port. A solutions architect must ensure that the service is highly available, has redundancy across Availability Zones, and is accessible using the DNS name my.service.com, which is publicly accessible. The service must use fixed address assignments so other companies can add the addresses to their allow lists.

Assuming that resources are deployed in multiple Availability Zones in a single Region, which solution will meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
A company is developing a web application that runs on Amazon EC2 instances in an Auto Scaling group behind a public-facing Application Load Balancer (ALB). Only users from a specific country are allowed to access the application. The company needs the ability to log the access requests that have been blocked. The solution should require the least possible maintenance.

Which solution meets these requirements?
Implementing cost control strategies Designing for security and compliance
A company is finalizing the architecture for its backup solution for applications running on AWS. All of the applications run on AWS and use at least two Availability Zones in each tier.

Company policy requires IT to durably store nightly backups for all its data in at least two locations: production and disaster recovery. The locations must be in different geographic regions. The company also needs the backup to be available to restore immediately at the production data center, and within 24 hours at the disaster recovery location. All backup processes must be fully automated.

What is the MOST cost-effective backup solution that will meet all requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Implementing cost control strategies
A company is having issues with a newly deployed serverless infrastructure that uses Amazon API Gateway, Amazon Lambda, and Amazon DynamoDB.

In a steady state, the application performs as expected. However, during peak load, tens of thousands of simultaneous invocations are needed and user requests fail multiple times before succeeding. The company has checked the logs for each component, focusing specifically on Amazon CloudWatch Logs for Lambda. There are no errors logged by the services or applications.

What might cause this problem?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company is hosting an image-processing service on AWS in a VPC. The VPC extends across two Availability Zones. Each Availability Zone contains one public subnet and one private subnet.

The service runs on Amazon EC2 instances in the private subnets. An Application Load Balancer in the public subnets is in front of the service. The service needs to communicate with the internet and does so through two NAT gateways. The service uses Amazon S3 for image storage. The EC2 instances retrieve approximately 1 " of data from an S3 bucket each day.

The company has promoted the service as highly secure. A solutions architect must reduce cloud expenditures as much as possible without compromising the service s security posture or increasing the time spent on ongoing operations.

Which solution will meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
A company is hosting a three-tier web application in an on-premises environment. Due to a recent surge in traffic that resulted in downtime and a significant financial impact, company management has ordered that the application be moved to AWS. The application is written in .NET and has a dependency on a MySQL database. A solutions architect must design a scalable and highly available solution to meet the demand of 200,000 daily users.

Which steps should the solutions architect take to design an appropriate solution?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company is implementing a multi-account strategy; however, the Management team has expressed concerns that services like DNS may become overly complex. The company needs a solution that allows private DNS to be shared among virtual private clouds (VPCs) in different accounts. The company will have approximately 50 accounts in total.

What solution would create the LEAST complex DNS architecture and ensure that each VPC can resolve all AWS resources?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Migrating complex, multi-tier applications on AWS
A company is in the process of implementing AWS Organizations to constrain its developers to use only Amazon EC2, Amazon S3, and Amazon DynamoDB. The Developers account resides in a dedicated organizational unit (OU). The Solutions Architect has implemented the following SCP on the Developers account:


When this policy is deployed, IAM users in the Developers account are still able to use AWS services that are not listed in the policy.

What should the Solutions Architect do to eliminate the Developers ability to use services outside the scope of this policy?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
