Microsoft 365 FundamentalsDescribe core Microsoft 365 services and conceptsMedium
A Microsoft 365 administrator is setting up a new tenant for an organization. They need to configure the default domain (e.g., contoso.onmicrosoft.com), add custom domains (e.g., contoso.com), and manage DNS records for email and other services. Which core Microsoft 365 component is responsible for handling these domain and identity-related configurations?
- AMicrosoft SharePoint Online
- BMicrosoft Teams
- CMicrosoft Exchange Online
- DAzure Active Directory
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Active Directory
Azure Active Directory (Azure AD) is the foundational identity and access management service in Microsoft 365. It manages user accounts, groups, domains, and authentication, including the configuration of custom domains and DNS records.
Why the other options are wrong
- A. SharePoint Online provides document management and team sites, but does not manage core identity or domains.
- B. Microsoft Teams is a collaboration platform and uses Azure AD for user identities and authentication.
- C. Exchange Online manages email services, mailboxes, and mail flow, but relies on Azure AD for domain management.
Azure Active Directory (Azure AD)
Microsoft's cloud-based identity and access management service, foundational for Microsoft 365.
- Manages user accounts, groups, and administrative roles.
- Handles domain management, including custom domains and DNS verification.
- Provides authentication and authorization for Microsoft 365 services and other cloud applications.
Memory trick: Azure AD is the 'Active Directory' for 'All' identities and domains.
