A company runs an application on Amazon EC2 instances behind an Application Load Balancer. The EC2 instances are in an Auto Scaling group. The application sometimes becomes slow and unresponsive. Amazon CloudWatch metrics show that some EC2 instances are experiencing high CPU load.

A SysOps administrator needs to create a CloudWatch dashboard that can automatically display CPU metrics of all the EC2 instances. The metrics must include new instances that are launched as part of the Auto Scaling group.

What should the SysOps administrator do to meet these requirements in the MOST operationally efficient way?

A. Create a CloudWatch dashboard. Use activity notifications from the Auto Scaling group to invoke a custom AWS Lambda function. Use the Lambda function to update the CloudWatch dashboard to monitor the CPUUtilization metric for the new instance IDs.
B. Create a CloudWatch dashboard. Run a custom script on each EC2 instance to stream the CPU utilization to the dashboard.
C. Use CloudWatch metrics explorer to filter by the aws:autoscaling:groupName tag and to create a visualization for the CPUUtilization metric. Add the visualization to a CloudWatch dashboard.
D. Use CloudWatch metrics explorer to filter by instance state and to create a visualization for the CPUUtilization metric. Add the visualization to a CloudWatch dashboard.

A company is expanding its use of AWS services across its portfolios. The company wants to provision AWS accounts for each team to ensure a separation of business processes for security, compliance, and billing. Account creation and bootstrapping should be completed in a scalable and efficient way so new accounts are created with a defined baseline and governance guardrails in place. A SysOps administrator needs to design a provisioning process that saves time and resources.

Which action should be taken to meet these requirements?

A. Automate using AWS Elastic Beanstalk to provision the AWS accounts, set up infrastructure, and integrate with AWS Organizations.
B. Create bootstrapping scripts in AWS OpsWorks and combine them with AWS CloudFormation templates to provision accounts and infrastructure.
C. Use AWS Config to provision accounts and deploy instances using AWS Service Catalog.
D. Use AWS Control Tower to create a template in Account Factory and use the template to provision new accounts.

A company has a workload that is sending log data to Amazon CloudWatch Logs. One of the fields includes a measure of application latency. A SysOps administrator needs to monitor the p90 statistic of this field over time.

What should the SysOps administrator do to meet this requirement?

A. Create an Amazon CloudWatch Contributor Insights rule on the log data.
B. Create a metric filter on the log data.
C. Create a subscription filter on the log data.
D. Create an Amazon CloudWatch Application Insights rule for the workload.

A company uses AWS Organizations to manage multiple AWS accounts. The company’s SysOps team has been using a manual process to create and manage IAM roles. The team requires an automated solution to create and manage the necessary IAM roles for multiple AWS accounts.

What is the MOST operationally efficient solution that meets these requirements?

A. Create AWS CloudFormation templates. Reuse the templates to create the necessary IAM roles in each of the AWS accounts.
B. Use AWS Directory Service with AWS Organizations to automatically associate the necessary IAM roles with Microsoft Active Directory users.
C. Use AWS Resource Access Manager with AWS Organizations to deploy and manage shared resources across the AWS accounts.
D. Use AWS CloudFormation StackSets with AWS Organizations to deploy and manage IAM roles for the AWS accounts.

A SysOps administrator is creating an Amazon EC2 Auto Scaling group in a new AWS account. After adding some instances, the SysOps administrator notices that the group has not reached the minimum number of instances. The SysOps administrator receives the following error message:

Launching a new EC2 instance. Status Reason: Your quota allows for 0 more running instance(s).
You requested at least 1. Launching EC2 instance failed.

Which action will resolve this issue?

A. Adjust the account spending limits for Amazon EC2 on the AWS Billing and Cost Management console.
B. Modify the EC2 quota for that AWS Region in the EC2 Settings section of the EC2 console.
C. Request a quota increase for the instance type family by using Service Quotas on the AWS Management Console.
D. Use the Rebalance action in the Auto Scaling group on the AWS Management Console.

A company hosts a web application on Amazon EC2 instances behind an Application Load Balancer. The instances are in an Amazon EC2 Auto Scaling group. The application is accessed with a public URL.

A SysOps administrator needs to implement a monitoring solution that checks the availability of the application and follows the same routes and actions as a customer. The SysOps administrator must receive a notification if less than 95% of the monitoring runs find no errors.

Which solution will meet these requirements?

A. Create an Amazon CloudWatch Synthetics canary with a script that follows customer routes. Schedule the canary to run on a recurring schedule. Create a CloudWatch alarm that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic when the SuccessPercent metric is less than 95%.
B. Create Amazon Route 53 health checks that monitor the availability of the endpoint. Create Amazon CloudWatch alarms that publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when the HealthCheckPercentageHealthy metric is less than 95%.
C. Create a single AWS Lambda function to check whether the endpoints are available for each customer path. Schedule the Lambda function by using Amazon EventBridge (Amazon CloudWatch Events). Configure the Lambda function to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when an endpoint returns an error.
D. Create an AWS Lambda function for each customer path to check whether that specific endpoint is available. Schedule the Lambda functions by using Amazon EventBridge (Amazon CloudWatch Events). Configure each Lambda function to publish a custom metric to Amazon CloudWatch for the endpoint status. Create CloudWatch alarms based on each custom metric to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when an alarm is in the ALARM state.

A company’s customers are reporting increased latency while accessing static web content from Amazon S3. A SysOps administrator observed a very high rate of read operations on a particular S3 bucket.

What will minimize latency by reducing load on the S3 bucket?

A. Migrate the S3 bucket to a region that is closer to end users’ geographic locations.
B. Use cross-region replication to replicate all of the data to another region.
C. Create an Amazon CloudFront distribution with the S3 bucket as the origin.

A. Purchase Reserved Instances for the jobs.
B. Submit a request for a one-time Spot Instance for the jobs.
C. Submit a request for Spot Instances with a defined duration for the jobs.
D. Use a mixture of On-Demand Instances and Spot Instances for the jobs.
