The correct answer is passwordless authentication because it enables users to access corporate resources without passwords while leveraging cryptographic key pairs or biometric verification through methods like Windows Hello for Business, FIDO2 security keys, or the Microsoft Authenticator app, thereby eliminating phishing and credential theft risks while maintaining high security. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this scenario tests your understanding of how Microsoft Entra ID supports passwordless authentication as a core identity security feature, often appearing in questions about modern authentication policies or conditional access. A common trap is confusing passwordless with multi-factor authentication alone—remember that passwordless replaces the password entirely, whereas MFA still requires something you know. Memory tip: think “no password, no phish”—passwordless authentication removes the weakest link.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 uses Microsoft Entra ID for identity management. You need to ensure that users can access corporate resources without passwords while maintaining a high level of security. Which feature should you implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Passwordless authentication
Passwordless authentication (Option C) is correct because it allows users to access corporate resources without entering a password, using methods like Windows Hello for Business, FIDO2 security keys, or the Microsoft Authenticator app. This eliminates password-related risks (e.g., phishing, credential theft) while maintaining strong security through cryptographic key pairs or biometric verification, aligning with the requirement for both password-free access and high security.
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.
✗
Azure AD B2C
Why it's wrong here
Azure AD B2C is for external identities, not for eliminating passwords for internal users.
✗
Conditional Access policies
Why it's wrong here
Conditional Access enforces access controls but does not remove the need for passwords.
✓
Passwordless authentication
Why this is correct
Passwordless methods allow users to sign in without a password, using biometrics or FIDO2 keys.

✗
Multifactor authentication (MFA)
Why it's wrong here
MFA adds an extra layer but still requires a password as one factor.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'passwordless' with 'multifactor authentication' (MFA), assuming MFA alone removes the password requirement, but MFA still requires a password as the first factor unless explicitly combined with a passwordless method.
Detailed technical explanation
How to think about this question
Passwordless authentication in Microsoft Entra ID leverages WebAuthn (FIDO2) or key-based authentication (e.g., asymmetric key pairs stored in TPM hardware) to replace passwords entirely. Under the hood, the device generates a public-private key pair; the private key never leaves the device, and authentication is verified via a challenge-response protocol, making it resistant to replay attacks. In a real-world scenario, a user with a FIDO2 security key can sign in to Azure AD-joined Windows 10/11 devices or web apps without ever typing a password, even if the network is untrusted.

→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.
