You need to set up a complex network infrastructure for your organization that will be reasonably easy to deploy, replicate, control, and track changes on. Which AWS service would be best to use to help you accomplish this?
Correct Answer:B
AWS CIoudFormation is a service that helps you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. You create a template that describes all the AWS resources that you want (like Amazon EC2 instances or Amazon RDS DB instances), and AWS CIoudFormation takes care of provisioning and configuring those resources for you. You don't need to indMdually create and configure AWS resources
and figure out what's dependent on what. AWS CIoudFormation handles all of that.

A user has created a CIoudFormation stack. The stack creates AWS services, such as EC2 instances, ELB, AutoScaIing, and RDS. While creating the stack it created EC2, ELB and AutoScaIing but failed to create RDS. What will C|oudFormation do in this scenario?
Correct Answer:A
AWS CIoudFormation is an application management tool which provides application modeling, deployment, configuration, management and related actMties. The AWS CIoudFormation stack is a collection of AWS resources which are created and managed as a single unit when AWS CIoudFormation instantiates a template. If any of the services fails to launch, C|oudFormation will rollback all the changes and terminate or delete all the created services.

A favored client needs you to quickly deploy a database that is a relational database service with minimal administration as he wants to spend the least amount of time administering it. Which database would be the best option?
Correct Answer:C
Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.
Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle, SQL Server, or PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery.
