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 →

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 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 →

A company is partnering with an external vendor to provide data processing services.For this integration, the vendor must host the company’s data in an AmazonS3 bucket in the vendor’s AWS account.The vendor is allowing the company to provide an AWS Key Management Service (AWS KMS) key to encrypt the company’s data.The vendor has provided an IAM role Amazon Resources Name (ARN) to the company for this integration.What should a SysOps administrator do to configure this integration?Read More →

A software development company has multiple developers who work on the same product.Each developer must have their own development environments, and these development environments must be identical.Each development environment consists of Amazon EC2 instances and an Amazon RDS DB instance.The development environments should be created only when necessary, and they must be terminated each night to minimize costs.What is the MOST operationally efficient solution that meets these requirements?Read More →

A SysOps administrator is notified that an Amazon EC2 instance has stopped responding.The AWS Management Console indicates that the system checks are failing.What should the administrator do first to resolve this issue?Read More →

The security team is concerned because the number of AWS Identity and Access Management (IAM) policies being used in the environment is increasing.The team tasked a SysOps administrator to report on the current number of IAM policies in use and the total available IAM policies.Which AWS service should the administrator use to check how current IAM policy usage compares to current service limits?Read More →

A company is using an Amazon CloudWatch alarm to monitor the FreeLocalStorage metric for an Amazon Aurora PostgreSQL production database.The alarm goes into ALARM state and indicates that the database is running low on temporary storage.A SysOps administrator discovers that a weekly report is using most of the temporary storage that is currently allocated.What should the SysOps administrator do to solve this problem?Read More →

A company is using an AWS KMS customer master key (CMK) with imported key material.The company references the CMK by its alias in the Java application to encrypt data.The CMK must be rotated every 6 months.What is the process to rotate the key?Read More →
