Amazon SOA-C02 Practice Test - Questions Answers, Page 48

A company is creating an application that runs on smart TVs and mobile phones. Static images for the application are loaded from an Amazon CloudFront distribution.

The images have large file sizes that result in a poor experience for users of mobile devices. The company has created a set of smaller images for mobile devices.

A SysOps administrator must configure CloudFront to cache different content based on the user's device type.

Which solution will meet this requirement?

A company deploys an application on AWS behind an internet-facing Application Load Balancer (ALB) in the us-west-2 Region. Amazon Route 53 manages DNS CNAME records for the application. The company is replicating its AWS infrastructure to the eu-west-2 Region.

A SysOps administrator must implement a Route 53 configuration to distribute application traffic across both Regions.

Which solution will meet these requirements with the LEAST application response time?

A company needs to copy an Amazon Aurora database from one AWS account to a second account that uses a second AWS Region. A SysOps administrator must automate this process to occur every day.

Which solution will meet these requirements with the LEAST operational overhead?

A company uses AWS Organizations to manage a set of AWS accounts. The company has set up organizational units (OUs) in the organization. An application OU supports various applications.

A SysOps administrator must prevent users from launching Amazon EC2 instances that do not have a CostCenter-Project tag into any account in the application OU. The restriction must apply only to accounts in the application OU.

Which solution will meet these requirements?

A company has implemented a data ingestion pipeline to process files in the form of messages. A frontend application accepts user input and stores the input in Amazon S3. A backend application uses Amazon EC2 instances to process the object that was uploaded to Amazon S3. The company recently experienced a significant increase in customer traffic. The frontend application is now sending more messages at one time than the backend application can handle, resulting in some lost messages.

Which action will resolve this problem with the LEAST operational effort?

A company is using an Amazon EC2 instance to inspect inbound traffic. The EC2 instance runs Amazon Linux and has the Amazon CloudWatch agent installed and configured.

The company needs to ingest metrics and logs from the EC2 instance into CloudWatch. The company also needs to receive notification when a specific number of errors occur for rejected web management requests. Which combination of steps will meet these requirements with the MOST operational efficiency? (Select TWO.)

A company operates compute resources in a VPC and in the company's on-premises data center. The company already has an AWS Direct Connect connection between the VPC and the on-premises data center. A SysOps administrator needs to ensure that Amazon EC2 instances in the VPC can resolve DNS names for hosts in the on-premises data center.

Which solution will meet this requirement with the LEAST amount of ongoing maintenance?

A company has two general purpose Amazon EC2 instances that run a software package. Each EC2 instance is attached to its own 500 GiB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume.

Each EBS volume frequently reaches its IOPS limit, negatively affecting workload performance. The company is starting a large promotion that will require 5 times more IOPS.

Which solution will meet these requirements?
