A company has an Amazon EC2 instance that supports a production system.The EC2 instance is backed by an Amazon Elastic Block Store (Amazon EBS) volume.The EBS volume’s drive has filled to 100% capacity, which is causing the application on the EC2 instance to experience errors.Which solution will remediate these errors in the LEAST amount of time?Read More →

A company stores data in Amazon S3 buckets that are provisioned in three separate AWS Regions.The data is copied from the S3 buckets to the data center over the public internet using a VPN.The SysOps administrator notices that, occasionally, the transfers take longer than usual, and determines the issue is congestion within the company’s ISP network.What is the MOST cost-effective approach the administrator can take to ensure consistent transfer times from S3 to the data center?Read More →

A company’s web application runs on Amazon EC2 instances in a single AWS Region.The infrastructure must be designed so the application remains available with no performance degradation in the event of an Availability Zone (AZ) failure.To ensure optimal performance, the application must maintain a minimum of 12 instances at all times.Which solution will meet the requirements with the fewest running instances possible?Read More →

A company stores its internal data within an Amazon S3 bucket.All existing data within the S3 bucket is protected by using server-side encryption with Amazon S3 managed encryption keys (SSE-S3).S3 Versioning is enabled.A SysOps administrator must replicate the internal data to another S3 bucket in a different AWS account for disaster recovery.All the existing data is copied from the source S3 bucket to the destination S3 bucket.Which replication solution is MOST operationally efficient?Read More →

A custom application must be installed on all Amazon EC2 instances.The application is small, updated frequently, and can be installed automatically.How can the application be deployed on new EC2 instances?Read More →

A company deploys a new application to Amazon EC2 instances.The application code is stored in an AWS CodeCommit repository.The company uses an AWS CodePipeline pipeline to deploy the code to the EC2 instances through a continuous integration and continuous delivery (CI/CD) process.A SysOps administrator needs to ensure that sensitive database information is configured properly on the EC2 instances to prevent accidental leakage of credentials.Which solutions will store and retrieve the sensitive information in the MOST secure manner? (Choose two.)Read More →

A SysOps administrator has many Windows Amazon EC2 instances that need to share a file system between nodes.The SysOps administrator creates an Amazon Elastic File System (Amazon EFS) file share.After creation of the file share, the SysOps administrator is having trouble mounting the file share to the EC2 instances.Which action should the SysOps administrator take so that the EC2 instances can share the files?Read More →

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.Which solution will meet these requirements?Read More →

A company recently acquired another corporation and all of that corporation’s AWS accounts.A financial analyst needs the cost data from these accounts.ASysOps administrator uses Cost Explorer to generate cost and usage reports.The SysOps administrator notices that “No Tagkey” represents 20% of the monthly cost.What should the SysOps administrator do to tag the “No Tagkey” resources?Read More →

A company is supposed to receive a data file every hour in an Amazon S3 bucket.An S3 event notification invokes an AWS Lambda function each time a file arrives.The function processes the data for use by an application.The application team notices that sometimes the file does not arrive.The application team wants to receive a notification whenever the file does not arrive.What is the MOST operationally efficient solution that meets these requirements?Read More →
