A company hosts an internal application on Amazon EC2 On-Demand Instances behind an Application Load Balancer (ALB).The instances are in an Amazon EC2 Auto Scaling group.Employees use the application to provide product prices to potential customers.The Auto Scaling group is configured with a dynamic scaling policy and tracks average CPU utilization of the instances.Employees have noticed that sometimes the application becomes slow or unresponsive.A SysOps administrator finds that some instances are experiencing a high CPU load.The Auto Scaling group cannot scale out because the company is reaching the EC2 instance service quota.The SysOps administrator needs to implement a solution that provides a notification when the company reaches 70% or more of the EC2 instance service quota.Which solution will meet these requirements in the MOST operationally efficient manner?Read More →
A DevOps engineer is tasked with creating a more stable deployment solution for a web application in AWS.Previous deployments have resulted in user-facing bugs, premature user traffic, and inconsistencies between web servers running behind an Application Load Balancer.The current strategy uses AWS CodeCommit to store the code for the application.When developers push to the main branch of the repository, CodeCommit triggers an AWS Lambda deploy function, which invokes an AWS Systems Manager run command to build and deploy the new code to all Amazon EC2 instances.Which combination of actions should be taken to implement a more stable deployment solution? (Choose two.)Read More →

A manufacturer is operating a large number of factories with a complex supply chain relationship where unexpected downtime of a machine can cause production to stop at several factories.A data scientist wants to analyze sensor data from the factories to identify equipment in need of preemptive maintenance and then dispatch a service team to prevent unplanned downtime.The sensor readings from a single machine can include up to 200 data points including temperatures, voltages, vibrations, RPMs, and pressure readings.To collect this sensor data, the manufacturer deployed Wi-Fi and LANs across the factories.Even though many factory locations do not have reliable or high- speed internet connectivity, the manufacturer would like to maintain near-real-time inference capabilities.Which deployment architecture for the model will address these business requirements?Read More →
