The answer is to deactivate the user in the connected identity provider, such as Active Directory. This is the most efficient way to revoke all AWS access for a departing employee using SSO because the identity provider (IdP) is the authoritative source for authentication; deactivating the user there immediately invalidates all existing SSO sessions and prevents any new ones from being created across every linked AWS account. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your understanding of centralized identity management versus account-level fixes—a common trap is choosing to delete IAM users or roles in individual accounts, which is inefficient and can break access for others. The key insight is that SSO shifts access control upstream to the IdP, so you revoke at the source, not the destination. Memory tip: think "cut the root, not the branches"—deactivate in the IdP, and all AWS accounts lose access instantly.
SCS-C02 Identity and Access Management Practice Question
This SCS-C02 practice question tests your understanding of identity and access management. 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 SSO to manage access to multiple accounts. An employee leaves the company. What is the most efficient way to revoke all AWS access for that employee?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deactivate the user in the connected identity provider (e.g., Active Directory).
Option B is correct because deactivating the user in the identity provider (IdP) will invalidate all sessions and prevent new ones. Option A is wrong because deleting the IAM user in each account is inefficient. Option C is wrong because removing from groups in AWS SSO may not immediately revoke active sessions. Option D is wrong because deleting the IAM role would break access for other users.
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.
✓
Deactivate the user in the connected identity provider (e.g., Active Directory).
Why this is correct
This immediately revokes all access across accounts via AWS SSO.
Related concept
Read the scenario before looking for a memorised answer.
✗
Delete the corresponding IAM user in every AWS account.
Why it's wrong here
With AWS SSO, IAM users are not created; access is via roles.
✗
Remove the user from all groups in AWS SSO.
Why it's wrong here
This may not terminate existing sessions immediately.
✗
Delete the IAM role that the user assumes in each account.
Why it's wrong here
Roles are shared; deleting them affects other users.

TExam Day Tips
→Underline the problem statement mentally.
→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.
