Tests All the questions in the book are provided in the form of review questions that are located at the end of each chapter. There is a 25-question assessment at the end of this introductory section. In addition, there are two practice exams with 50 questions each. Use these questions to test your knowledge of the study guide material. The online test bank runs on multiple devices.
Flashcards The online test banks include 100 flashcards specifically written to quiz your knowledge of operations on AWS. After completing all of the exercises, review questions, practice exams, and flashcards, you should be more than ready to take the exam. The flashcard questions are provided in a digital flashcard format (a question followed by a single correct answer with URL links for additional information). You can use the flashcards to reinforce your learning and provide last-minute test prep before the exam.

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?
A. Nothing. The command will be ignored until you create and apply a maintenance window.
B. Nothing. It is not possible to change the DB size using Amazon RDS.
C. AWS will select and use a default maintenance window if one is not provided.
D. AWS will prompt you to provide a maintenance window when you make the request.

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
