Amazon (SAP-C01) Exam Questions And Answers page 8

A company has decided to move some workloads onto AWS to create a grid environment to run market analytics. The grid will consist of many similar instances, spun-up by a job-scheduling function. Each time a large analytics workload is completed, a new VPC is deployed along with job scheduler and grid nodes. Multiple grids could be running in parallel.

Key requirements are:

• Grid instances must communicate with Amazon S3 to retrieve data to be processed.
• Grid instances must communicate with Amazon DynamoDB to track intermediate data.
• The job scheduler needs only to communicate with the Amazon EC2 API to start new grid nodes.

A key requirement is that the environment has no access to the internet, either directly or via the on-premises proxy. However, the application needs to be able to seamlessly communicate to Amazon S3, Amazon DynamoDB, and Amazon EC2 API, without the need for reconfiguration for each new deployment.

Which of the following should the Solutions Architect do to achieve this target architecture? (Choose three.)
Designing highly available, cost-efficient, fault-tolerant, scalable systems Implementing cost control strategies
A company has deployed an application to multiple environments in AWS, including production and testing. The company has separate accounts for production and testing, and users are allowed to create additional application users for team members or services, as needed. The Security team has asked the Operations team for better isolation between production and testing with centralized controls on security credentials and improved management of permissions between environments.

Which of the following options would MOST securely accomplish this goal?
Designing enterprise-wide scalable operations on AWS Designing for security and compliance
A company has developed a custom tool used in its workflow that runs within a Docker container. The company must perform manual steps each time the container code is updated to make the container image available to new workflow executions. The company wants to automate this process to eliminate manual effort and ensure a new container image is generated every time the tool code is updated.

Which combination of actions should a solutions architect take to meet these requirements? (Choose three.)
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company has developed a mobile game. The backend for the game runs on several virtual machines located in an on-premises data center. The business logic is exposed using a REST API with multiple functions. Player session data is stored in central file storage. Backend services use different API keys for throttling and to distinguish between live and test traffic.

The load on the game backend varies throughout the day. During peak hours, the server capacity is not sufficient. There are also latency issues when fetching player session data. Management has asked a solutions architect to present a cloud architecture that can handle the game s varying load and provide low-latency data access. The API model should not be changed.

Which solution meets these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company has developed a new billing application that will be released in two weeks. Developers are testing the application running on 10 EC2 instances managed by an Auto Scaling group in subnet 172.31.0.0/24 within VPC A with CIDR block 172.31.0.0/16. The Developers noticed connection timeout errors in the application logs while connecting to an Oracle database running on an Amazon EC2 instance in the same region within VPC B with CIDR block 172.50.0.0/16. The IP of the database instance is hard-coded in the application instances.

Which recommendations should a Solutions Architect present to the Developers to solve the problem in a secure way with minimal maintenance and overhead?
Designing enterprise-wide scalable operations on AWS Designing for security and compliance
A company has developed a new release of a popular video game and wants to make it available for public download. The new release package is approximately 5 GB in size. The company provides downloads for existing releases from a Linux-based, publicly facing FTP site hosted in an on-premises data center. The company expects the new release will be downloaded by users worldwide. The company wants a solution that provides improved download performance and low transfer costs, regardless of a user s location.

Which solutions will meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A company has developed a web application that runs on Amazon EC2 instances in one AWS Region. The company has taken on new business in other countries and must deploy its application into other regions to meet low-latency requirements for its users. The regions can be segregated, and an application running in one region does not need to communicate with instances in other regions.

How should the company s Solutions Architect automate the deployment of the application so that it can be MOST efficiently deployed into multiple regions?
Designing enterprise-wide scalable operations on AWS
A company has developed a web application. The company is hosting the application on a group of Amazon EC2 instances behind an Application Load Balancer. The company wants to improve the security posture of the application and plans to use AWS WAF web ACLs. The solution must not adversely affect legitimate traffic to the application.

How should a solutions architect configure the web ACLs to meet these requirements?
Designing for security and compliance
A company has five physical data centers in specific locations around the world. Each data center has hundreds of physical servers with a mix of Windows and Linux-based applications and database services. Each data center also has an AWS Direct Connect connection of 10 Gbps to AWS with a company-approved VPN solution to ensure that data transfer is secure. The company needs to shut down the existing data centers as quickly as possible and migrate the servers and applications to AWS.

Which solution meets these requirements?
Migrating complex, multi-tier applications on AWS Designing enterprise-wide scalable operations on AWS
A company has implemented an ordering system using an event driven architecture. During initial testing, the system stopped processing orders. Further log analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SQS) standard queue was causing an error on the backend and blocking all subsequent order messages. The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages.

Which step should the solutions architect take to meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
