A company wants to reduce costs for jobs that can be completed at any time. The jobs currently run by using multiple Amazon EC2 On-Demand Instances and the jobs take slightly less than 2 hours to complete. If a job falls for any reason it must be restarted from the beginning.
Which solution will meet these requirements MOST cost-effectively?

  1. Purchase Reserved Instances for the jobs.
  2. Submit a request for a one-time Spot Instance for the jobs.
  3. Submit a request for Spot Instances with a defined duration for the jobs.
  4. Use a mixture of On-Demand Instances and Spot Instances for the jobs.

Answer(s): C



An environment consists of 100 Amazon EC2 Windows instances. The Amazon CloudWatch agent is deployed and running on all EC2 Instances with a baseline configuration file to capture log files. There is a new requirement to capture the DHCP log files that exist on 50 of the instances.
What is the MOST operationally efficient way to meet this new requirement?

  1. Create an additional CloudWatch agent configuration file to capture the DHCP logs. Use the AWS Systems Manager Run Command to restart the CloudWatch agent on each EC2 instance with the append-config option to apply the additional configuration file.
  2. Log in to each EC2 Instance with administrator rights. Create a PowerShell script to push the needed baseline log files and DHCP log files to CloudWatch.
  3. Run the CloudWatch agent configuration file wizard on each EC2 instance. Verify that the baseline log files are included and add the DHCP log files during the wizard creation process.
  4. Run the CloudWatch agent configuration file wizard on each EC2 instance and select the advanced detail level. This will capture the operating system log files.

Answer(s): A



A company has 10 Amazon EC2 instances in its production account. A SysOps administrator must ensure that email notifications are sent to administrators each time there is an EC2 instance state change.
Which solution will meet this requirements?

  1. Configure an Amazon Route 53 simple routing policy that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic when an EC2 instance state changes. This SNS topic then sends notifications to its email subscribers.
  2. Configure an Amazon Route 53 simple routing policy that publishes a message to an Amazon Simple Queue Service (Amazon SQS) queue when an EC2 instance state changes. This SQS queue then sends notifications to its email subscribers.
  3. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic when an EC2 instance state changes. This SNS topic then sends notifications to its email subscribers.
  4. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that publishes a message to an Amazon Simple Queue Service (Amazon SQS) queue when an EC2 instance state changes. This SQS queue then sends notifications to its email subscribers.

Answer(s): C



A company has an application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer. The instances run in an Auto Scaling group. The application's performance remains consistent throughout most of each day. However, an increase in user traffic slows the performance during the same 4-hour period of time each day.
What is the MOST operationally efficient solution that will resolve this issue?

  1. Configure a second Elastic Load Balancer in front of the Auto Scaling group with a weighted routing policy.
  2. Configure the fleet of EC2 instances to run on larger instance types to support the increase in user traffic.
  3. Create a scheduled scaling action to scale out the number of EC2 instances shortly before the increase in user traffic occurs.
  4. Manually add a few more EC2 instances to the Auto Scaling group to support the increase in user traffic.

Answer(s): C
