A company is using an Amazon EC2 Auto Scaling group to support a workload.A SysOps administrator finds that the Auto Scaling group is configured with two similar scaling policies.One scaling policy adds 5 instances when CPU utilization reaches 80%.The other scaling policy adds 10 instances when CPU utilization reaches 80%.What will happen when CPU utilization reaches the 80% threshold?Read More →

An application uses an Amazon Aurora MySQL DB cluster that includes one Aurora Replica.The application’s read performance degrades when there are more than 200 user connections.The number of user connections is approximately 180 on a consistent basis.Occasionally, the number of user connections increases rapidly to more than 200.A SysOps administrator must implement a solution that will scale the application automatically as user demand increases or decreases.Which solution will meet these requirements?Read More →

A company hosts an application on Amazon EC2 instances.The instances are in an Amazon EC2 Auto Scaling group that uses a launch template.The amount of application traffic changes throughout the day.Scaling events happen frequently.A SysOps administrator needs to help developers troubleshoot the application.When a scaling event removes an instance, EC2 Auto Scaling terminates the instance before the developers can log in to the instance to diagnose issues.Which solution will prevent termination of the instance so that the developers can log in to the instance?Read More →

A company has a cluster of Linux Amazon EC2 Spot Instances that read many files from and write many files to attached Amazon Elastic Block Store (Amazon EBS) volumes.The EC2 instances are frequently started and stopped.As part of the process when an EC2 instance starts, an EBS volume is restored from a snapshot.EBS volumes that are restored from snapshots are experiencing initial performance that is lower than expected.The company’s workload needs almost all the provisioned IOPS on the attached EBS volumes.The EC2 instances are unable to support the workload when the performance of the EBS volumes is too low.A SysOps administrator must implement a solution to ensure that the EBS volumes provide the expected performance when they are restored from snapshots.Which solution will meet these requirements?Read More →

A SysOps administrator needs to monitor a process that runs on Linux Amazon EC2 instances.If the process stops, the process must restart automatically.The Amazon CloudWatch agent is already installed on all the EC2 instances.Which solution will meet these requirements?Read More →

A SysOps administrator is responsible for the security of a company’s AWS account.The company has a policy that a user may stop or terminate Amazon EC2 instances only when the user is authenticated by using a multi-factor authentication (MFA) device.Which policy should the SysOps administrator apply to meet this requirement?Read More →

A company is using AWS Certificate Manager (ACM) to manage public SSL/TLS certificates.A SysOps administrator needs to send an email notification when a certificate has less than 14 days until expiration.Which solution will meet this requirement with the LEAST operational overhead?Read More →

A SysOps administrator created an AWS CloudFormation template that provisions an Amazon EventBridge rule that invokes an AWS Lambda function.The Lambda function is designed to write event details to an Amazon CloudWatch log group.The function has permissions to write events to Amazon CloudWatch Logs.However, the SysOps administrator discovered that the Lambda function is not running.How should the SysOps administrator resolve the problem?Read More →

A company has an Amazon EC2 instance that has high CPU utilization.The EC2 instance is a t3.large instance and is running a test web application.The company discovers that the web application would operate better on a compute optimized large instance.What should a SysOps administrator do to make this change?Read More →

A company observes that a newly created Amazon CloudWatch alarm is not transitioning out of the INSUFFICIENT_DATA state.The alarm was created to track the mem_used_percent metric from an Amazon EC2 instance that is deployed in a public subnet.A review of the EC2 instance shows that the unified CloudWatch agent is installed and is running.However, the metric is not available in CloudWatch.A SysOps administrator needs to implement a solution to resolve this problem.Which solution will meet these requirements?Read More →
