DOP-C02 SDLC Automation Practice Question

This DOP-C02 practice question tests your understanding of sdlc automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company has a multi-account AWS environment using AWS Organizations. The DevOps team wants to deploy a CloudFormation stack set to all accounts in the organization. Which IAM permissions are REQUIRED for the stack set execution role?

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

✓

iam:PassRole

The stack set execution role requires the `iam:PassRole` permission because CloudFormation uses this role to create, update, or delete stacks in target accounts. When deploying a stack set, the service passes the execution role ARN to the target accounts, and the calling principal must have `iam:PassRole` on that role to authorize the delegation. Without this permission, CloudFormation cannot assume the role in the target accounts to perform stack operations.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    iam:PassRole

    Why this is correct

    The execution role must pass the stack set admin role to CloudFormation.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    sts:AssumeRole

    Why it's wrong here

    While assumed, alone it does not allow CloudFormation to create resources.

  • ✗

    cloudformation:CreateStackSet

    Why it's wrong here

    This is an administrative action, not needed by the execution role.

  • ✗

    iam:*

    Why it's wrong here

    This is overly broad and not a best practice.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse the permissions needed for the calling principal (e.g., `cloudformation:CreateStackSet`) with the permissions required for the execution role itself, or mistakenly think `sts:AssumeRole` is needed on the caller side instead of on the role's trust policy.

Detailed technical explanation

How to think about this question

Under the hood, when CloudFormation deploys a stack set, it uses the execution role's ARN to call `sts:AssumeRole` in each target account, which returns temporary credentials scoped to that account. The `iam:PassRole` permission must be granted to the CloudFormation service principal (or the delegated administrator) on the execution role resource, and the role's trust policy must allow `sts:AssumeRole` from the CloudFormation service. In a real-world scenario, if the execution role is in a different account (e.g., a central security account), the `iam:PassRole` permission must be explicitly allowed across accounts using a resource-based policy.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
