Amazon Exam DVA-C02 Topic 1 Question 35 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 35
Topic #: 1

A developer needs to build an AWS CloudFormation template that self-populates the AWS Region variable that deploys the CloudFormation template

What is the MOST operationally efficient way to determine the Region in which the template is being deployed?

AUse the AWS:.Region pseudo parameter

BRequire the Region as a CloudFormation parameter

CFind the Region from the AWS::Stackld pseudo parameter by using the Fn::Split intrinsic function

DDynamically import the Region by referencing the relevant parameter in AWS Systems Manager Parameter Store

Show Suggested Answer

Suggested Answer: A

Pseudo Parameters:CloudFormation provides pseudo parameters that reference runtime context, including the current AWS Region.

Operational Efficiency:TheAWS::Regionpseudo parameter offers the most direct and self-contained way to obtain the Region dynamically within the template.

Haha, this question is a real brainteaser. I'm just picturing the developer trying to figure out the Region by reading tea leaves or something.

C'mon, guys, using Fn::Split on the AWS::StackId is just too much work. Why not keep it simple with the AWS::Region pseudo parameter?

I think dynamically importing the Region by referencing the relevant parameter in AWS Systems Manager Parameter Store is the best option.

Ooh, I'd go with option D. Dynamically importing the Region from AWS Systems Manager Parameter Store seems like a really flexible and future-proof solution.

I personally prefer finding the Region from the AWS::StackId pseudo parameter using the Fn::Split intrinsic function.

I think the most efficient way is to use the AWS::Region pseudo parameter. That way, the Region is automatically detected and doesn't need to be manually set as a parameter.
