What is the benefit of using Azure AD B2B collaboration?

Correct answer: To securely share applications with external partner organizations while maintaining identity control

Option C is correct because Azure AD B2B (Business-to-Business) collaboration allows an organization to invite external users from partner organizations to access internal applications and resources while the external users authenticate with their own identity provider, meaning the inviting organization retains control over what is shared without managing partner credentials. Option A is incorrect because data replication across Azure regions is handled by features like geo-redundant storage or Azure Site Recovery, not by B2B collaboration. Option B is incorrect because hosting or managing multiple Azure subscriptions is a billing and management scope concern addressed by Azure Management Groups and Enterprise Agreements, not B2B. Option D is incorrect because hybrid cloud deployments connecting on-premises infrastructure to Azure are managed by services such as Azure Arc or Azure VPN Gateway, not B2B collaboration.
