SC-900 Practice Question: Describe the concepts of security, compliance, and identity
Which TWO of the following are identity-related security best practices recommended by Microsoft? (Choose two.)
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
✓
Implement Conditional Access policies
The correct answers are B and E. Implementing Conditional Access policies allows organizations to enforce access controls based on conditions, which is a best practice for identity security. Enabling multi-factor authentication (MFA) adds an extra layer of security beyond passwords. Option A is incorrect because sharing passwords violates security best practices. Option C is incorrect because SSO without MFA does not provide adequate protection. Option D is incorrect because disabling sign-in logs reduces visibility and hinders security monitoring.
