A company runs an application on Amazon EC2 instances that are in an Amazon EC2 Auto Scaling group.Scale-out actions take a long time to become complete because of long-running boot scripts.A SysOps administrator must implement a solution to reduce the required time for scale-out actions without overprovisioning the Auto Scaling group.Which solution will meet these requirements?Read More →

A company analyzes sales data for its customers.Customers upload files to one of the company’s Amazon S3 buckets, and a message is posted to an AmazonSimple Queue Service (Amazon SQS) queue that contains the object Amazon Resource Name (ARN).An application that runs on an Amazon EC2 instance polls the queue and processes the messages.The processing time depends on the size of the file.Customers are reporting delays in the processing of their files.A SysOps administrator decides to configure Amazon EC2 Auto Scaling as the first step.TheSysOps administrator creates an Amazon Machine Image (AMI) that is based on the existing EC2 instance.The SysOps administrator also creates a launch template that references the AMI.How should the SysOps administrator configure the Auto Scaling policy to improve the response time?Read More →

A SysOps administrator is optimizing the cost of a workload.The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the computer.The overall usage is predictable.The amount of computer that is consumed in each Region varies, depending on the users’ locations.Which approach should the SysOps administrator use to optimize this workload?Read More →

An ecommerce company has built a web application that uses an Amazon Aurora DB cluster.The DB cluster includes memory optimized instance types with both a writer node and a reader node.Traffic volume changes throughout the day.During sudden traffic surges, Amazon CloudWatch metrics for the DB cluster indicate high RAM consumption and an increase in select latency.A SysOps administrator must implement a configuration change to improve the performance of the DB cluster.The change must minimize downtime and must not result in the loss of data.Which change will meet these requirements?Read More →

An AWS Lambda function is intermittently failing several times a day.A SysOps administrator must find out how often this error has occurred in the last 7 days.Which action will meet this requirement in the MOST operationally efficient manner?Read More →
