This MS-900 practice question tests your understanding of describe cloud concepts. 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.
Exhibit
{"policyAssignment":{"properties":{"displayName":"Require MFA for all users","policyDefinitionId":"/providers/Microsoft.Authorization/policyDefinitions/1f7f9b2c-3a4b-5c6d-7e8f-9a0b1c2d3e4f","parameters":{"effect":{"value":"Deny"}}}}}
Refer to the exhibit. The policy assignment JSON shows an Azure Policy that requires MFA for all users. What is the effect of this policy?
{"policyAssignment":{"properties":{"displayName":"Require MFA for all users","policyDefinitionId":"/providers/Microsoft.Authorization/policyDefinitions/1f7f9b2c-3a4b-5c6d-7e8f-9a0b1c2d3e4f","parameters":{"effect":{"value":"Deny"}}}}}
A
Allow access temporarily for non-compliant users
Why wrong: 'Deny' blocks access, not allows.
B
Audit non-compliant users and log to Azure Monitor
Why wrong: The effect is 'Deny', not 'Audit'.
C
Block the creation or modification of resources that do not have MFA enabled
'Deny' effect prevents non-compliant actions from being completed.
D
Automatically create a support ticket for non-compliant users
Why wrong: No automatic ticket creation is defined.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Block the creation or modification of resources that do not have MFA enabled
Option D is correct because the effect is set to 'Deny', which blocks non-compliant requests. Option A is wrong because 'Audit' is not present. Option B is wrong because 'Deny' does not allow; it blocks. Option C is wrong because 'Deny' does not create a support ticket.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
