The answer is that the delegated administrator account lacks the required IAM permissions to manage IPAM. While AWS Organizations delegation authorizes the account to act on behalf of the organization for IPAM, it does not automatically grant the specific IAM actions needed to create IPAM pools, such as `ec2:CreateIpamPool`. This is a common point of confusion because delegation and IAM permissions are separate layers of access control—delegation enables organizational scope, but IAM policies still govern what API calls the account can make. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of how IPAM integrates with Organizations and the common trap of assuming delegation grants full permissions. Remember, delegation is like handing someone the keys to the building, but IAM is the key to each individual door. A useful memory tip: “Delegation opens the org, IAM opens the action.”
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 uses AWS Organizations with multiple accounts. The network team wants to centrally manage Amazon VPC IP addresses using Amazon VPC IP Address Manager (IPAM). They have enabled IPAM in the management account and delegated an administrator account. However, the delegated administrator account cannot create IPAM pools. What is the most likely cause?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The delegated administrator account does not have the required IAM permissions to manage IPAM
Option A is correct because when you delegate an administrator account for IPAM in AWS Organizations, that account still requires explicit IAM permissions to perform IPAM actions such as creating pools. The delegation only allows the account to manage IPAM resources on behalf of the organization; it does not automatically grant the necessary IAM permissions. Without a policy that allows actions like `ec2:CreateIpamPool`, the delegated administrator will receive an authorization error.
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.
✓
The delegated administrator account does not have the required IAM permissions to manage IPAM
Why this is correct
IAM permissions are necessary for the delegated account to perform IPAM actions.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
IPAM must be used only from the management account and cannot be delegated
Why it's wrong here
IPAM supports delegated administrators.
✗
IPAM is not supported in the AWS Region where the delegated administrator account operates
Why it's wrong here
IPAM is supported in most commercial regions.
✗
An SCP in the organization denies IPAM actions for all accounts
Why it's wrong here
If SCP denied IPAM, the management account would also be affected.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume delegation in AWS Organizations automatically grants full administrative permissions, but in reality, IAM policies are still required for the delegated account to perform specific actions.
Detailed technical explanation
How to think about this question
IPAM uses a hierarchical pool structure where top-level pools are created in the management account or delegated administrator, and child pools can be allocated to member accounts. The delegated administrator must have an IAM policy that includes `ec2:CreateIpamPool`, `ec2:ModifyIpamPool`, and related actions, along with permissions to view and allocate CIDRs. A common misconfiguration is granting only `IPAM` read permissions or forgetting that delegation does not bypass IAM—it only authorizes the account to act as the IPAM administrator.

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.
