The answer is to enable GuardDuty in the management account and designate a delegated administrator to centralize findings across all accounts. This is the most efficient approach because AWS Organizations allows you to enable GuardDuty at the organizational level with a single click, automatically provisioning the service in every member account. The delegated administrator account then receives all findings from the entire organization, providing a single pane of glass for threat detection without manual per-account setup. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding of multi-account security architecture and the distinction between GuardDuty’s native organization-wide enablement versus Security Hub’s aggregation role. A common trap is choosing Security Hub, which aggregates findings but does not enable GuardDuty itself, or EventBridge, which handles automation but not provisioning. Memory tip: think “Org-level enablement first, then delegate the dashboard” — GuardDuty does the heavy lifting, not the aggregator.
SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. 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 multiple accounts. The security team wants to centralize threat detection and automatically remediate high-severity GuardDuty findings across all accounts. What is the MOST efficient way to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable GuardDuty in the management account and designate a delegated administrator to manage findings across all accounts
Option A is correct because GuardDuty can be enabled at the organization level, and findings are sent to a delegated administrator account. Option B is wrong because enabling manually in each account is inefficient. Option C is wrong because Security Hub aggregates findings but does not enable GuardDuty automatically. Option D is wrong because EventBridge alone does not enable GuardDuty across accounts.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable GuardDuty in the management account and designate a delegated administrator to manage findings across all accounts
Why this is correct
GuardDuty organization-level management automates enablement and centralizes findings.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a Lambda function that enables GuardDuty in each account using cross-account IAM roles
Why it's wrong here
This is manual and less efficient than organization-level management.
✗
Configure Amazon EventBridge to forward findings from each account to a central account
Why it's wrong here
EventBridge forwards events but does not automate enablement.
✗
Use AWS Security Hub and enable GuardDuty in each account separately
Why it's wrong here
Security Hub aggregates but does not automate GuardDuty enablement.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SCS-C02 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Enable GuardDuty in the management account and designate a delegated administrator to manage findings across all accounts — Option A is correct because GuardDuty can be enabled at the organization level, and findings are sent to a delegated administrator account. Option B is wrong because enabling manually in each account is inefficient. Option C is wrong because Security Hub aggregates findings but does not enable GuardDuty automatically. Option D is wrong because EventBridge alone does not enable GuardDuty across accounts.
