Only a Fabric admin can create top-level domains; domain admin handles subdomains

Configure security and governance
Answer Correct answer: D — Only a Fabric admin can create a new top-level domain; domain admin and domain contributor cannot create the domain itself.

Your company has a sales department that uses two Fabric workspaces named Workspace1 and Workspace2. The company decides to implement a domain strategy to organize the workspaces. You need to ensure that a user can perform the following tasks: Create a new domain for the sales department. Create two subdomains: one for the east region and one for the west region. Assign Workspace1 to the east region subdomain. Assign Workspace2 to the west region subdomain. The solution must follow the principle of least privilege. Which role should you assign to the user?

  1. workspace Admin
  2. domain admin
  3. domain contributor
  4. Fabric admin Correct Answer

Community Insight

Domain creation is a Fabric-admin-only capability; the principle of least privilege here still requires Fabric admin because no lower role can create a domain at all.

Creating a new top-level domain in Microsoft Fabric requires the Fabric admin role. A domain admin can create and manage subdomains and assign workspaces within an existing domain, but cannot create the parent domain itself.

Assigning domain admin and assuming it covers creating the top-level domain; domain admin authority begins after a Fabric admin creates the domain.

The Domain Contributor role provides the exact permissions needed to create subdomains and assign workspaces, without granting excessive privileges. Therefore, C is the best choices

The question states that user should be able to create Domains. Hence, answer should be D. https://learn.microsoft.com/en-us/fabric/onelake/onelake-shortcuts

Domain Admin Domain contributors are workspace Admins (will only be relevant to one workspace) https://learn.microsoft.com/en-us/fabric/governance/domains#domain-roles

Given answer is correct since the domain admin can create a new subdomain but a domain contributor cannot.
IshtarSQL 👍 1 Selected: C
Not B because: Domain Admin: While this role provides higher-level control over domains and subdomains, it exceeds the principle of least privilege for this scenario.

Why the Answer Is Correct

Fabric domain documentation states that only Fabric admins (or higher) can create and edit domains. The scenario requires creating a brand-new domain for the sales department, which is exclusively a Fabric admin capability. Although the same user must later create subdomains and assign workspaces, those tasks can be performed by a domain admin, but the initial domain creation cannot be done without Fabric admin.

Why the Other Options Are Wrong

Option B (domain admin) can create subdomains and assign workspaces but cannot create the top-level domain. Option C (domain contributor) has even narrower rights and cannot create domains or subdomains. Option A (workspace admin) governs a single workspace and has no domain-creation authority.

Community Comment Notes

Community voting strongly favors D (79 vs 15). Multiple comments (neo_20, MDWPartners, benni_ale) confirm only a Fabric admin can create domains, with several noting a domain admin could handle the subdomains once the domain exists.
