D.
CloudFormation templates are parsed in advance so stack creation is guaranteed to succeed.
Answers
Suggested answer: B

Explanation:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacks.htmlAWS CloudFormation ensures all stack resources are created or deleted as appropriate. Because AWSCloudFormation treats the stack resources as a single unit, they must all be created or deleted successfully for the stack to be created or deleted. If a resource cannot be created, AWSCloudFormation rolls the stack back and automatically deletes any resources that were created. If are source cannot be deleted, any remaining resources are retained until the stack can be successfully deleted.

E.
By default, all request are allowed
Answers
Suggested answer: A, C

Explanation:

https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.htmlBy default, all requests are implicitly denied. (Alternatively, by default, the AWS account root user has full access.) An explicit allow in an identity- based or resource-based policy overrides this default.

If a permissions boundary, Organizations SCP, or session policy is present, it might override the allow with an implicit deny. An explicit deny in any policy overrides any allows.
