The answer is the `aws:MultiFactorAuthPresent` condition key. This key is correct because it evaluates to a Boolean value of `true` when the user has authenticated using MFA, and `false` when they have not. By placing this condition in a `Deny` effect statement within an IAM policy, the administrator can block all AWS Management Console actions unless MFA is present, directly enforcing the security team’s requirement. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of IAM policy condition keys for enforcing MFA, a common security scenario. A frequent trap is confusing this key with `aws:MultiFactorAuthAge`, which checks how long ago MFA was used, not whether it is present. For a quick memory tip, think of the key as a simple “MFA present? Yes or no?” switch—if the answer is no, the policy denies access.
SOA-C02 Security and Compliance Practice Question
This SOA-C02 practice question tests your understanding of security and compliance. 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's security team requires that all IAM users must use multi-factor authentication (MFA) to access the AWS Management Console. The SysOps administrator needs to create an IAM policy that denies all console actions if the user has not authenticated with MFA. Which IAM condition key should the administrator use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
aws:MultiFactorAuthPresent
Option A is correct because the `aws:MultiFactorAuthPresent` condition key evaluates to `true` when the user has authenticated using MFA. By using this key in a `Deny` statement, the policy can block all console actions unless MFA is present, enforcing the security team's requirement.
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.
✓
aws:MultiFactorAuthPresent
Why this is correct
This condition key returns true if the user authenticated with MFA. It is the correct key to use in an IAM policy to require MFA for console access.
Related concept
Read the scenario before looking for a memorised answer.
✗
aws:SourceIp
Why it's wrong here
The aws:SourceIp condition key restricts access based on the IP address of the requester. It is not related to MFA status.
✗
iam:PassedToService
Why it's wrong here
The iam:PassedToService condition key is used when passing roles to AWS services. It does not check MFA usage.
✗
aws:RequestedRegion
Why it's wrong here
The aws:RequestedRegion condition key restricts access to specific AWS Regions. It does not relate to MFA authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `aws:MultiFactorAuthPresent` with `aws:MultiFactorAuthAge` (which checks how long ago MFA was used) or assume `SourceIp` can enforce MFA, but only the `MultiFactorAuthPresent` key directly evaluates MFA status for console access.
Detailed technical explanation
How to think about this question
The `aws:MultiFactorAuthPresent` key is a boolean condition key that returns `true` only if the user authenticated with a valid MFA device (e.g., hardware TOTP token or virtual MFA). In a policy, you combine it with `Deny` and `aws:SecureTransport` to also enforce MFA for API calls; note that the key is not present for long-term credentials used without MFA, so you must check for `false` or use `Null` condition to block unauthenticated sessions.

→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.
