SC-300 Lab Tips:

Tenant Name vs Tenant’s unique name:

Tenant Name (a.k.a. Directory Name)
- This is the display name you assign to your Azure/Entra tenant.
- You can set or change this to something human-readable like "Marketing" or "MyCompany Directory".
- It’s shown in places like the Azure portal and Microsoft Entra admin center.
- e.g. Tenant Name: Bluewave Innovations

Tenant’s Unique Name (bluewave123)
- This is the automatically generated subdomain prefix used for your default .onmicrosoft.com domain.
- It’s globally unique and tied to your tenant forever.
- It’s often used behind the scenes (e.g., when no custom domain is set, during app registrations, etc.)
- You can’t change this once the tenant is created.

In your case: bluewave123.onmicrosoft.com

Term	Example	Editable?	Purpose/Use
Tenant Name	Bluewave Innovations	✅ Yes	Display name in UI, for organizing/admin use
Unique Tenant Name	bluewave123	❌ No	Part of your default domain, system-assigned
Tenant ID	a12b3456-...	❌ No	Globally unique identifier (GUID)

💡

You can use yourdomain.com as the tenant name — it’s allowed — but for a cleaner and more polished look, using just the organization name is more common.
