Your

mission is to create a lights-out datacenter environment, and you plan to use AWS OpsWorks to accomplish this. First you created a stack and added an App Server layer with an instance running in it. Next you added an application to the instance, and now yo

u need to deploy a MySQL RDS database instance.

Which of the following answers accurately describe how to add a backend database server to an OpsWorks stack? (Choose three.)

A. Add a new database layer and then add recipes to the deploy actions of the dat

abase and App Server layers.

B. Use OpsWorks -Clone Stack- feature to create a second RDS stack in another Availability Zone for redundancy in the event of a failure in the Primary AZ. To switch to the secondary RDS instance, set the [:database] attribute

s to values that are appropriate for your server which you can do by using custom JSON.

C. The variables that characterize the RDS database connection-”host, user, and so on-”are set using the corresponding values from the deploy JSONs [:depioy][:app_name][

:database] attributes.

D. Cookbook attributes are stored in a repository, so OpsWorks requires that the -password-: -your_password- attribute for the RDS instance must be encrypted using at least a 256-bit key.

E. Set up the connection between the app serv

er and the RDS layer by using a custom recipe. The recipe configures the app server as required, typically by creating a configuration file. The recipe gets the connection data such as the host and database name from a set of attributes in the stack config

uration and deployment JSON that AWS OpsWorks installs on every instance.
