Question 44

What happens, by default, when one of the resources in a CloudFormation stack cannot be created?
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.
Question 45

Which of the following are correct statements with policy evaluation logic in AWS Identity and Access Management? Choose 2 answers
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.
