- A
Microsoft Entra Connect Health, Microsoft Entra ID with cloud sync, and Azure AD Identity Protection.
Why wrong: Connect Health is for monitoring; cloud sync is for synchronization but does not provide MFA enforcement.
- B
Microsoft Entra Connect Sync, Microsoft Entra ID, and Conditional Access policies with MFA.
Connect Sync syncs identities; Entra ID provides authentication and conditional access can require MFA via Authenticator.
- C
Active Directory Federation Services (AD FS), Web Application Proxy, and Azure AD Conditional Access.
Why wrong: AD FS is on-premises, not necessary; adds complexity.
- D
Azure AD Pass-through Authentication, Azure AD Application Proxy, and Azure AD Identity Protection.
Why wrong: Pass-through Authentication does not support MFA via Authenticator; Identity Protection is not for MFA enforcement.
Quick Answer
The correct answer is Microsoft Entra Connect Sync, Microsoft Entra ID, and Conditional Access policies with MFA. This combination works because Entra Connect Sync bridges your on-premises Active Directory with the cloud, replicating user credentials so that authentication occurs against Entra ID while still honoring on-premises password policies. Conditional Access policies then evaluate the sign-in risk and enforce MFA via the Microsoft Authenticator app, which requires a cloud-based authentication method rather than a pass-through or federated flow. On the AZ-305 exam, this scenario tests your understanding of how hybrid identity components layer together for security and compliance; a common trap is choosing Pass-Through Authentication, which cannot natively support the Authenticator app’s push notifications, or adding AD FS unnecessarily. Remember the memory tip: “Sync, Sign, and Secure”—Entra Connect Sync for identity, Entra ID for sign-in, and Conditional Access for securing with MFA.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure solutions. 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.
Your company has a hybrid identity environment using Microsoft Entra ID (formerly Azure AD) and on-premises Active Directory. You need to design a solution that allows users to authenticate to Azure services using their on-premises credentials and enforce conditional access policies for sensitive applications. The solution must support multi-factor authentication (MFA) using the Microsoft Authenticator app. Which components should you include?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Entra Connect Sync, Microsoft Entra ID, and Conditional Access policies with MFA.
Option C is correct because Microsoft Entra Connect Sync synchronizes identities, Entra ID provides authentication, and conditional access policies enforce MFA. Option A is wrong because Pass-through Authentication does not support MFA via Authenticator app. Option B is wrong because AD FS is an additional component that adds complexity. Option D is wrong because Microsoft Entra Connect Health is for monitoring, not authentication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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.

Variation 1. Your company is designing a hybrid identity solution that will allow users to authenticate to Azure resources using their on-premises Active Directory credentials. The solution must support multi-factor authentication (MFA) and conditional access policies. Which TWO components should you include?
medium- ✓ A.Microsoft Entra Connect
- B.Active Directory Federation Services (AD FS)
- ✓ C.Microsoft Entra ID
- D.Azure AD Application Proxy
- E.Microsoft Intune
Why A: Options A and D are correct. Microsoft Entra Connect syncs identities to the cloud, and Microsoft Entra ID provides the authentication and policy enforcement. Option B is wrong because ADFS is not required if using password hash sync or pass-through authentication with MFA. Option C is wrong because Intune is for device management, not authentication. Option E is wrong because Azure AD Application Proxy is for publishing on-prem apps.
