A company is performing deployments of an application at regular intervals. Users report that the application sometimes does not work properly. The company discovers that some users ' browsers are fetching previous versions of the JavaScript files. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB is the origin for an Amazon CloudFront distribution.
A SysOps administrator must implement a solution to ensure that CloudFront serves the latest version of the JavaScript files. The solution must not affect application server performance.
Which solution will meet these requirements?

• A.Remove CloudFront from the path of serving JavaScript files. Serve the JavaScript files directly through the ALB.
• B.Add a final step in the deployment process to invalidate all files in the CloudFront distribution.
• C.Add a final step in the deployment process to invalidate only the changed JavaScript files in the CloudFront distribution.
• D.Reduce the maximum TTL and default TTL of the CloudFront distribution behavior to 0.

A company needs to enforce tagging requirements for Amazon DynamoDB tables in its AWS accounts. A CloudOps engineer must implement a solution to identify and remediate all DynamoDB tables that do not have the appropriate tags.
Which solution will meet these requirements with the LEAST operational overhead?

• A.Use the required-tags AWS Config managed rule to evaluate all DynamoDB tables for the appropriate tags. Configure an automatic remediation action that uses an AWS Systems Manager Automation custom runbook.
• B.Create an Amazon EventBridge managed rule to evaluate all DynamoDB tables for the appropriate tags. Configure the EventBridge rule to run an AWS Systems Manager Automation custom runbook for remediation.
• C.Create a custom AWS Lambda function to evaluate and remediate all DynamoDB tables. Create an Amazon EventBridge scheduled rule to invoke the Lambda function.
• D.Create a custom AWS Lambda function to evaluate and remediate all DynamoDB tables. Create an AWS Config custom rule to invoke the Lambda function.

A company uses hundreds of Amazon EC2 On-Demand Instances and Spot Instances to run production and non-production workloads. The company installs and configures the AWS Systems Manager Agent (SSM Agent) on the EC2 instances.
During a recent instance patch operation, some instances were not patched because the instances were either busy or down. The company needs to generate a report that lists the current patch version of all instances.
Which solution will meet these requirements in the MOST operationally efficient way?

• A.Use AWS Config to track EC2 instance configuration changes by using output from the SSM Agents.
  Create a custom rule to check for patch versions. Generate a report of all unpatched instances.
• B.Use Systems Manager Inventory to collect patch versions. Generate a report of all instances.
• C.Use AWS Config to monitor the patch status of the EC2 instances by using output from the SSM Agents. Create a configuration compliance rule to check whether patches are installed. Generate a report of all instances.
• D.Use Systems Manager Run Command to remotely collect patch version information. Generate a report of all instances.

A company has users that deploy Amazon EC2 instances that have more volume performance capacity than is required. A CloudOps engineer needs to review all Amazon Elastic Block Store (Amazon EBS) volumes that are associated with the instances and create cost optimization recommendations based on IOPS and throughput.
What should the CloudOps engineer do to meet these requirements in the MOST operationally efficient way?

• A.Install the fio tool onto the EC2 instances and create a .cfg file to approximate the required workloads.Use the benchmark results to gauge whether the provisioned EBS volumes are of the most appropriate type.
• B.Use the monitoring graphs in the EC2 console to view metrics for EBS volumes. Review the consumed space against the provisioned space on each volume. Identify any volumes that have low utilization.
• C.Stop the EC2 instances from the EC2 console. Change the EC2 instance type to Amazon EBS- optimized. Start the EC2 instances.
• D.Opt in to AWS Compute Optimizer. Allow sufficient time for metrics to be gathered. Review the Compute Optimizer findings for EBS volumes.

A company runs databases on Amazon RDS for MySQL DB instances. The company must generate database backups every 12 hours for all the DB instances. The company must retain the backups for 5 years.
A CloudOps engineer needs to develop an automated solution to generate and retain the database backups.
Which solution will meet these requirements with the LEAST operational overhead?

• A.Configure an Amazon EventBridge rule to call the RDS CreateDBSnapshot API operation. Set the backup frequency to 12 hours. Set the retention period to 5 years.
• B.Use AWS Backup to create an automated backup job in Amazon RDS. Set the backup frequency to 12 hours. Set the retention period to 5 years.
• C.Enable RDS automated backups. Set the backup frequency to 12 hours. Set the retention period to 5 years.
• D.Configure an AWS Lambda function to call the RDS CreateDBSnapshot API operation every 12 hours.
  Copy the snapshots to Amazon S3. Set up an S3 Lifecycle policy to retain the snapshots for 5 years.
