A company has established tagging and configuration standards for its infrastructure resources running on AWS. A DevOps Engineer is developing a design that will provide a near-real-time dashboard of the compliance posture with the ability to highlight violations. Which approach meets the stated requirements?
A DevOps Engineer is working on a project that is hosted on Amazon Linux and has failed a security review. The DevOps Manager has been asked to review the company buildspec.yaml file for an AWS CodeBuild project and provide recommendations. The buildspec.yaml file is configured as follows:
A Development team is building more than 40 applications. Each app is a three-tiered web application based on an ELB Application Load Balancer, Amazon EC2, and Amazon RDS. Because the applications will be used internally, the Security team wants to allow access to the 40 applications only from the corporate network and block access from external IP addresses. The corporate network reaches the internet through proxy servers. The proxy servers have 12 proxy IP addresses that are being changed one or two times per month. The Network Infrastructure team manages the proxy servers; they upload the file that contains the latest proxy IP addresses into an Amazon S3 bucket. The DevOps Engineer must build a solution to ensure that the applications are accessible from the corporate network. Which solution achieves these requirements with MINIMAL impact to application development, MINIMAL operational effort, and the LOWEST infrastructure cost?
A DevOps Engineer administers an application that manages video files for a video production company. The application runs on Amazon EC2 instances behind an ELB Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. Data is stored in an Amazon RDS PostgreSQL Multi-AZ DB instance, and the video files are stored in an Amazon S3 bucket. On a typical day, 50 GB of new video are added to the S3 bucket. The Engineer must implement a multi-region disaster recovery plan with the least data loss and the lowest recovery times. The current application infrastructure is already described using AWS CloudFormation.
Which deployment option should the Engineer choose to meet the uptime and recovery objectives for the system?
A government agency is storing highly confidential files in an encrypted Amazon S3 bucket. The agency has configured federated access and has allowed only a particular on-premises Active Directory user group to access this bucket.
The agency wants to maintain audit records and automatically detect and revert any accidental changes administrators make to the IAM policies used for providing this restricted federated access. Which of the following options provide the FASTEST way to meet these requirements?
