      3. You have deployed eight Amazon Elastic Compute Cloud (Amazon EC2) instances in the us-west-1a Availability Zone and two Amazon EC2 instances in us-west-1b Availability Zone. You noticed that the two Amazon EC2 instances in us-west-1b received the same amount of traffic that is load balanced between the other eight Amazon EC2 instances located in the us-west-1a Availability Zone. How can you fix this from the load balancer?

      A. Enable cross-load balancing on your load balancer.

      B. Create an Auto Scaling group, and configure it to balance out the instances between the Availability Zones.

      C. Create three instances in us-west-1b, and terminate three instances in us-west-1a.

      D. Migrate to an Application load balancer.

      4. You have launched an Amazon Relational Database Service (Amazon RDS) database instance running MySQL. When you created the Amazon RDS instance, you did not specify a maintenance window, and now you need to update the instance size from micro to large. If you request to have the update happen inside the maintenance window, what will occur?

      B. Amazon EBS gp2

      C. Amazon Simple Storage Service (Amazon S3)

      D. Amazon Elastic File System (Amazon EFS)

      7. You need storage for your production MySQL database. The database is 19 TB in size, and you will need to have approximately 10,000 IOPS – mostly writes. Without considering price, which storage option satisfies the requirements?

      A. Provisioned Amazon Elastic File System (Amazon EFS) 20 TB volume with 10,000 IOPS

      B. Two provisioned Amazon EFS 10 TB volumes with 5,000 IOPS per volume and RAID0 striping
