Amazon SOA-C02 Practice Test - Questions Answers, Page 36

A company's SysOps administrator maintains a highly available environment. The environment includes Amazon EC2 instances and an Amazon RDS Multi-AZ database. The EC2 instances are in an Auto Scaling group behind an Application Load Balancer.

Recently, the company conducted a failover test. The SysOps administrator needs to decrease the failover time of the RDS database by at least 10%.

Which solution will meet this requirement?

A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status.

All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications.

Which solution will meet these requirements?

A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack.

A company has an application that runs behind an Application Load Balancer (ALB) in the us-west-2 Region. An Amazon Route 53 record set contains an alias record for app.anycompany.com that references the ALB in us-west-2 and uses a simple routing policy. The application is experiencing an increase in users from other locations in the world. These users are experiencing high latency.

Most of the new users are close to the ap-southeast-2 Region. The company deploys a copy of the application to ap-southeast-2. A SysOps administrator must implement a solution that automatically routes requests to the lowest latency endpoint for users without changing the URL.

Which solution will meet these requirements?

A company has applications that process transaction requests multiple times each minute. The applications write transaction data to a single Amazon RDS DB instance. As the company begins to process more transactions, the company becomes concerned that it has no failover solution in place for disaster recovery (DR).

A company is running a development application on an Amazon EC2 instance. The application uploads 500.000 files that are 1 GB in size into a large! Amazon S3 bucket that has default encryption enabled The EC2 instance is in the same AWS Region where the S3 bucket is deployed.

The company uses performance logging that is built into the application software. The logs show that the application is constantly waiting for the files to be written to the S3 bucket. A SysOps administrator needs to improve the application's throughput performance. The SysOps administrator validates that the networking on the EC2 instance is not constrained.

What should the SysOps administrator do to improve the S3 upload performance''
