A company plans to deploy a database on an Amazon Aurora MySQL DB cluster. The database will store data for a demonstration environment. The data must be reset on a daily basis.

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

  1. Create a manual snapshot of the DB cluster after the data has been populated. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the snapshot and then delete the previous DB cluster.
  2. Enable the Backtrack feature during the creation of the DB cluster. Specify a target backtrack window of 48 hours. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to perform a backtrack operation.
  3. Export a manual snapshot of the DB cluster to an Amazon S3 bucket after the data has been populated. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the snapshot from Amazon S3.
  4. Set the DB cluster backup retention period to 2 days. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster.

A SysOps administrator is setting up an automated process to recover an Amazon EC2 instance in the event of an underlying hardware failure. The recovered instance must have the same private IP address and the same Elastic IP address that the original instance had. The SysOps team must receive an email notification when the recovery process is initiated.

Which solution will meet these requirements?

  1. Create an Amazon CloudWatch alarm for the EC2 instance, and specify the StatusCheckFailed_Instance metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.
  2. Create an Amazon CloudWatch alarm for the EC2 instance, and specify the StatusCheckFailed_System metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.
  3. Create an Auto Scaling group across three different subnets in the same Availability Zone with a minimum, maximum, and desired size of 1. Configure the Auto Scaling group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to send an email message to the SysOps team through Amazon Simple Email Service (Amazon SES).
  4. Create an Auto Scaling group across three Availability Zones with a minimum, maximum, and desired size of 1. Configure the Auto Scaling group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.

Answer(s): B



A company has a public website that recently experienced problems. Some links led to missing webpages, and other links rendered incorrect webpages. The application infrastructure was running properly, and all the provisioned resources were healthy. Application logs and dashboards did not show any errors, and no monitoring alarms were raised. Systems administrators were not aware of any problems until end users reported the issues.

The company needs to proactively monitor the website for such issues in the future and must implement a solution as soon as possible.

Which solution will meet these requirements with the LEAST operational overhead?

  1. Rewrite the application to surface a custom error to the application log when issues occur. Automatically parse logs for errors. Create an Amazon CloudWatch alarm to provide alerts when issues are detected.
  2. Create an AWS Lambda function to test the website. Configure the Lambda function to emit an Amazon CloudWatch custom metric when errors are detected. Configure a CloudWatch alarm to provide alerts when issues are detected.
  3. Create an Amazon CloudWatch Synthetics canary. Use the CloudWatch Synthetics Recorder plugin to generate the script for the canary run. Configure the canary in line with requirements. Create an alarm to provide alerts when issues are detected.
  4. In the Amazon CloudWatch console, turn on Application Insights. Create a CloudWatch alarm to provide alerts when an issue is detected.

Answer(s): C



A SysOps administrator is responsible for a company’s security groups. The company wants to maintain a documented trail of any changes that are made to the security groups. The SysOps administrator must receive notification whenever the security groups change.

Which solution will meet these requirements?

  1. Set up Amazon Detective to record security group changes. Specify an Amazon CloudWatch Logs log group to store configuration history logs. Create an Amazon Simple Queue Service (Amazon SQS) queue for notifications about configuration changes. Subscribe the SysOps administrator’s email address to the SQS queue.
  2. Set up AWS Systems Manager Change Manager to record security group changes. Specify an Amazon CloudWatch Logs log group to store configuration history logs. Create an Amazon Simple Notification Service (Amazon SNS) topic for notifications about configuration changes. Subscribe the SysOps administrator’s email address to the SNS topic.
  3. Set up AWS Config to record security group changes. Specify an Amazon S3 bucket as the location for configuration snapshots and history files. Create an Amazon Simple Notification Service (Amazon SNS) topic for notifications about configuration changes. Subscribe the SysOps administrator’s email address to the SNS topic.
  4. Set up Amazon Detective to record security group changes. Specify an Amazon S3 bucket as the location for configuration snapshots and history files. Create an Amazon Simple Notification Service (Amazon SNS) topic for notifications about configuration changes. Subscribe the SysOps administrator’s email address to the SNS topic.

Answer(s): C

It's my first review so excuse me if I overlooked any etiquettes or etc. I had been studying off and on since Nov. I received a 790 a few hours ago and what I did was the following: Took the practice tests and got a passing score a couple times in a row Overall, I'd say that everything provided for reasonable price by along with the dumps helped me out the most. All of that plus just not psyching yourself out about the difficulty of the exam, picking a date and forcing yourself to be ready by that date should pretty much set you up for success.
