An organization uses AWS CloudFormation to deploy resources across multiple AWS accounts. They need to manage a common set of resources in several accounts from a single template. Which CloudFormation feature should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
StackSets
StackSets allow deploying stacks across multiple accounts and regions. Change sets show changes before execution; Drift Detection detects configuration drift; Nested stacks are for reusability within a single account.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change sets
Why it's wrong here
Change sets preview how proposed stack modifications affect existing resources before execution; they do not span accounts. The option tempts because they manage template changes, but the requirement is deploying one template into several accounts, which needs StackSets with administrative and target accounts.
- ✗
Nested stacks
Why it's wrong here
Nested stacks compose multiple templates within one account and region; they cannot deploy the same template into separate AWS accounts. They are tempting because they do centralise shared resource definitions, but that reuse is intra-account, whereas cross-account deployment requires StackSets with target accounts and regions.
- ✗
Drift Detection
Why it's wrong here
Drift detection only reports where deployed stack resources diverge from their template; it cannot provision or share resources across accounts. It is tempting because it does compare templates against reality, but that is for auditing existing stacks, not for deploying one common template into several accounts.
- ✓
StackSets
Why this is correct
StackSets deploy a single CloudFormation template across multiple AWS accounts and regions from one administration account, satisfying the requirement to manage common resources in several accounts centrally. Stack policies, change sets, and nested stacks operate within one account, so they cannot span accounts.
