How to Pass the Amazon Web Services SOA-C01 Exam: Comprehensive AWS Certified SysOps Administrator - Associate Guide and Tips

An application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Auto Scaling group across multiple Availability Zones. The Information Security team wants to track application requests by the originating IP and the EC2 instance that processes the request.

Which of the following tools or services provides this information?

A SysOps Administrator working on an Amazon EC2 instance has misconfigured the clock by one hour. The EC2 instance is sending data to Amazon CloudWatch through the CloudWatch agent. The timestamps on the logs are 45 minutes in the future.

What will be the result of this configuration?

A company runs an Amazon RDS MySQL DB instance. Corporate policy requires that a daily backup of the database must be copied to a separate security account.

What is the MOST cost-effective way to meet this requirement?

A company relies on a fleet of Amazon EC2 instances to support an application. One of the EC2 instances was scheduled for hardware maintenance by AWS. An operations team did not remove the EC2 instance from the fleet in advance of the scheduled maintenance, and an unplanned outage resulted. A SysOps administrator must configure notifications to let the operations team know about scheduled maintenance in the future.

An application running on Amazon EC2 allows users to launch batch jobs for data analysis. The jobs are run asynchronously, and the user is notified when they are complete. While multiple jobs can run concurrently, a user’s request need not be fulfilled for up to 24 hours. To run a job, the application launches an additional EC2 instance that performs all the analytics calculations. A job takes between 75 and 110 minutes to complete and cannot be interrupted.

What is the MOST cost-effective way to run this workload?
