The answer is to delegate an administrator account for IPAM and then use AWS Resource Access Manager (RAM) to share the IPAM pool with member accounts. This is required because IPAM operates at the organization level, and only a delegated administrator can centrally manage IP address space without granting full access to the management account. RAM then enables cross-account sharing of the IPAM pool, allowing member accounts to allocate CIDRs from the centrally managed pool while maintaining account isolation. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of how to combine AWS Organizations, IPAM, and RAM for scalable network governance—a common trap is assuming the management account must perform all actions directly. Remember the mnemonic: **DARE**—Delegate an Admin, then RAM to Enable sharing.
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 and wants to centralize Amazon VPC IP Address Manager (IPAM) across multiple accounts. Which TWO steps are required to enable cross-account IPAM?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Share the IPAM pool using AWS Resource Access Manager (RAM).
Option C is correct because AWS Resource Access Manager (RAM) is the service used to share IPAM pools across accounts in an AWS Organization. Sharing the pool allows member accounts to allocate CIDRs from the centrally managed pool without needing direct access to the management account. This enables centralized IP address management while maintaining account isolation.
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.
✗
Create a PrivateLink endpoint for IPAM.
Why it's wrong here
PrivateLink is not needed for IPAM.
✗
Enable VPC sharing in each member account.
Why it's wrong here
VPC sharing is for sharing subnets, not IPAM.
✓
Share the IPAM pool using AWS Resource Access Manager (RAM).
Why this is correct
RAM enables sharing IPAM pools across accounts.

✗
Set up AWS Direct Connect between accounts.
Why it's wrong here
Direct Connect is for dedicated network connections, not for IPAM.
✓
Delegate an administrator account for IPAM.
Why this is correct
IPAM requires a delegated administrator account.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse IPAM pool sharing (which uses RAM) with VPC sharing or network connectivity services like Direct Connect, leading them to select irrelevant options that address different aspects of multi-account networking.
Detailed technical explanation
How to think about this question
IPAM uses a hierarchical pool structure where a top-level pool is created in the management account, and sub-pools can be shared via RAM to member accounts. When a member account allocates a CIDR from a shared pool, IPAM automatically tracks utilization and enforces CIDR allocation rules (e.g., avoiding overlaps) across the entire organization. This is particularly useful in large multi-account environments where consistent IP address planning is critical, such as in mergers or when using overlapping CIDRs for non-production environments.

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.
