AWS Certified SysOps Administrator - Associate

A media analytics company operates 320 Amazon EC2 instances in a single AWS Region (280 Amazon Linux 2 and 40 Windows Server 2019) that are all managed with AWS Systems Manager Session Manager, and each instance carries an os=linux or os=windows tag. A zero-day affecting a network protocol has no vendor patch, and the security team has supplied two mitigation payloads: a Bash script for Linux and a PowerShell script for Windows. The SysOps administrator must deploy the correct script to every instance without reboots or agent changes and must deliver within 30 minutes an auditable report proving the script executed successfully on all targeted instances. What should the SysOps administrator do to meet these requirements as quickly as possible?

In an AWS Organizations environment, a DevOps team uses AWS CloudFormation StackSets (service-managed permissions) to deploy template version 12 to 5 member accounts across us-east-1 and eu-west-1, and in account 003456789012 the update operation op-123 targeting eu-west-1 fails and the stack instance reports status OUTDATED—what is the most likely cause of this status?

A gaming analytics platform runs an Amazon EC2 Auto Scaling group across two Availability Zones behind an Application Load Balancer; every new instance must include a lightweight telemetry agent (1.2 MB) that is updated weekly, installs non-interactively in under 30 seconds, and must always be the latest version at launch while scale-out events can add up to 50 instances within 60 minutes. What is the most operationally efficient way to ensure the agent is deployed on new EC2 instances?

A SysOps administrator has deployed a standardized Amazon ECS cluster by using an AWS CloudFormation template in a sandbox account. The company has 35 member accounts across two organizational units (OUs) in AWS Organizations and needs the same stack deployed to us-east-1, us-west-2, and eu-west-1 in all current and future accounts in those OUs. Which solution will meet this requirement with the least ongoing operational overhead?

A media analytics firm provisions Amazon RDS for MySQL Multi-AZ DB instances with an AWS CloudFormation template that sets allocated storage to 120 GiB, creates the databases every Tuesday at 08:00 UTC and deletes them the following Saturday at 20:00 UTC, and occasionally a heavy batch load causes FreeStorageSpace to drop below 10 GiB and trigger an Amazon CloudWatch alarm; to prevent the databases from running low on storage in the future with the fewest changes to the application, what should a SysOps administrator do?
