    A major TV network has a web application running on eight Amazon T3 EC2 instances. The number of requests that the application processes are consistent and do not experience spikes. To ensure that eight instances are running at all times, the Solutions Architect should create an Auto Scaling group and distribute the load evenly between all instances.

    Which of the following options can satisfy the given requirements?

    1. Deploy two EC2 instances with Auto Scaling in four regions behind an Amazon Elastic Load Balancer.

    2. Deploy four EC2 instances with Auto Scaling in one Availability Zone and four in another availability zone in the same region behind an Amazon Elastic Load Balancer.

    3. Deploy four EC2 instances with Auto Scaling in one region and four in another region behind an Amazon Elastic Load Balancer.

    4. Deploy eight EC2 instances with Auto Scaling in one Availability Zone behind an Amazon Elastic Load Balancer.

    While the system says that the correct answer is option 2, I might be completely crazy here, but none of these options are correct. The explicitly says that 8 instances MUST be running >>>> all the times <<<< …. how is option 2 correct? if you lose one AZ, you will have only 4 instances running. The only viable option would be 8 instances in one AZ, and another 8 instances in another AZ…. thoughts?

    Hello andre,

    Thanks for bringing this item to our attention. We appreciate it.

    Yes, you’re right. The condition should be “to ensure the application is running at all times” and not the instances themselves. I’ve already made the necessary changes, and they should be reflected once our admin has reviewed them.

    Let me know if you have further questions.
