The correct answer is to set up a Systems Manager inventory in each account and grant the DevOps team IAM roles with AssumeRole permissions to each account. This works because it leverages AWS Security Token Service (STS) to allow the centralized team to assume a role in each target account, enabling cross-account Systems Manager centralized management without granting direct IAM access. The assumed role provides temporary credentials that authorize Systems Manager actions like Run Command or Patch Manager from a central account, while the inventory setup ensures visibility into managed instances. On the SAP-C02 exam, this scenario tests your understanding of how to combine AWS Organizations, IAM roles, and Systems Manager for secure, scalable operations—a common trap is trying to use VPC peering or direct IAM users in each account, which violates the “no direct access” constraint. Memory tip: “Assume to manage” — if the team cannot log in directly, they must assume a role to perform Systems Manager actions across accounts.
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 uses AWS Organizations with a multi-account strategy. They want to allow a centralized DevOps team to manage EC2 instances across all accounts using AWS Systems Manager. The DevOps team should not have direct IAM access to the target accounts. How can this be achieved?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up a Systems Manager inventory in each account and grant the DevOps team IAM roles with AssumeRole permissions to each account.
Option A is correct because it uses AWS Systems Manager's cross-account management capability combined with IAM roles. By setting up Systems Manager inventory in each target account and granting the DevOps team IAM roles with AssumeRole permissions, the team can centrally manage EC2 instances without having direct IAM access to those accounts. This leverages the AWS Security Token Service (STS) to assume a role in each target account, allowing Systems Manager actions like Run Command or Patch Manager to be executed from a central account.
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.
✓
Set up a Systems Manager inventory in each account and grant the DevOps team IAM roles with AssumeRole permissions to each account.
Why this is correct
Cross-account IAM roles allow centralized management without sharing credentials.
Related concept
Read the scenario before looking for a memorised answer.
✗
Install Systems Manager agent on all instances and manage them from a central account without any IAM roles.
Why it's wrong here
Systems Manager requires IAM roles for cross-account management.
✗
Create an SCP that allows Systems Manager actions in all accounts and assign it to the DevOps IAM role.
Why it's wrong here
SCPs do not grant permissions; they only restrict them.
✗
Share the EC2 console credentials of each account with the DevOps team.
Why it's wrong here
Sharing credentials is a security risk and not scalable.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Service Control Policies (SCPs) with IAM policies, thinking SCPs can grant permissions, when in fact SCPs only provide a guardrail by denying or allowing permissions that are then further restricted by IAM policies.
Detailed technical explanation
How to think about this question
Under the hood, this solution uses AWS Systems Manager's ability to assume an IAM role in a target account via the `sts:AssumeRole` API. The central DevOps account initiates a Systems Manager API call (e.g., `SendCommand`) that includes the ARN of the IAM role in the target account. Systems Manager then uses that role to interact with the SSM Agent on EC2 instances, which must have an instance profile with permissions to communicate with the Systems Manager service. A real-world scenario is a large enterprise with hundreds of accounts where a central operations team needs to apply patches or run scripts across all environments without granting them direct console access.

Key takeaway

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.
