Exam AWS Certified SysOps Administrator - Associate topic 1 question 129 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 129
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

A SysOps administrator is creating two AWS CloudFormation templates. The first template will create a VPC with associated resources, such as subnets, route tables, and an internet gateway. The second template will deploy application resources within the VPC that was created by the first template. The second template should refer to the resources created by the first template.

How can this be accomplished with the LEAST amount of administrative effort?

  • A. Add an export field to the outputs of the first template and import the values in the second template.
  • B. Create a custom resource that queries the stack created by the first template and retrieves the required values.
  • C. Create a mapping in the first template that is referenced by the second template.
  • D. Input the names of resources in the first template and refer to those names in the second template as a parameter.

Selected Answer: A
Note: To reference a resource in another AWS CloudFormation stack, you must first create cross-stack references. To create a cross-stack reference, use the export field to flag the value of a resource output for export.

here are some old comments A is correct! The optional Mappings section matches a key to a corresponding set of named values. For example, if you want to set values based on a region, you can create a mapping that uses the region name as a key and contains the values you want to specify for each specific region. You use the Fn::FindInMap intrinsic function to retrieve values in a map. You can't include parameters, pseudo parameters, or intrinsic functions in the Mappings section. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/mappings-section-structure.html A is correct, mappings have nothing to do in referencing from one stack to the other
