The answer is to use SAML-based federation with an identity provider that requires MFA. AWS Client VPN supports SAML 2.0-based identity federation, which allows the VPN endpoint to offload authentication to an external IdP; when that IdP is configured to enforce multi-factor authentication, every VPN connection inherently requires MFA before the client can establish the tunnel. This tests your understanding of how AWS Client VPN integrates with external identity sources rather than relying on its own certificate-based or directory-based authentication, which alone cannot enforce a second factor. On the ANS-C01 exam, a common trap is to confuse mutual authentication with client certificates or to assume that integrating with Active Directory automatically provides MFA—neither does unless the IdP itself enforces it. Remember the memory tip: “SAML shifts the MFA burden to the IdP; certificates and AD alone are single-factor.”
ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is using AWS Client VPN to allow remote employees to access resources in a VPC. The security team wants to enforce multi-factor authentication (MFA) for all VPN connections. Which configuration should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use SAML-based federation with an identity provider that requires MFA
AWS Client VPN supports mutual authentication and can use SAML-based identity federation with an IdP that requires MFA. Option A is wrong because client certificates alone do not enforce MFA. Option B is wrong because Active Directory alone does not enforce MFA. Option D is wrong because security groups do not enforce authentication.
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.
✗
Attach a security group to the Client VPN endpoint that only allows MFA-authenticated traffic
Use mutual authentication with client certificates
Why it's wrong here
Client certificates provide authentication but not MFA.
✓
Use SAML-based federation with an identity provider that requires MFA
Why this is correct
SAML federation allows integration with an IdP that can enforce MFA.

→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

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.
