Tutorial / Cram Notes
Microsoft Azure Stack Hub is an extension of Microsoft Azure, bringing the agility and innovation of cloud computing to on-premises environments. In managing Azure Stack Hub, you may have a team with different responsibilities, and you might wish to delegate specific management tasks to certain users without giving them full administrative rights. To accommodate this kind of delegation, you can define custom roles in Azure Active Directory (Azure AD).
Custom roles in Azure AD let you grant precise permissions to users based on their job function or role within the organization. This ensures that users have the access they need to perform their tasks, without unnecessary access that could pose a security risk.
Steps to Define a Custom Role in Azure AD:
- Open Azure Portal:
- Start by logging into the Azure portal.
- Select Azure Active Directory:
- From the left navigation panel, select Azure Active Directory.
- Go to Roles and Administrators:
- Click on ‘Roles and administrators’ to view existing roles.
- Create a New Role:
- Choose ‘New custom role’ to start defining your custom role.
- Define Role Settings:
- Enter a name and description for the role that reflects the tasks the role is meant to perform.
- Assign Permissions:
- Permissions are grouped into categories. Expand a category and check the specific permissions you want to include in the custom role.
- Assignable Scopes:
- Define the scopes that this role can be assigned. Scopes can be specific resource groups or the entire subscription.
- Review and Create:
- Review the settings for your new custom role and click ‘Create’ to create the role.
Example of a Custom Role for Azure Stack Hub Management:
Suppose you want to create a custom role called “Stack Hub Operator” whose responsibilities include restarting VMs, reading resource logs, and managing network settings, but not deleting resources or managing users.
- Name: Stack Hub Operator
- Description: Can perform operational tasks on VMs and networks without deletions or user management.
Permissions could include:
- Microsoft.Compute/virtualMachines/start/action
- Microsoft.Compute/virtualMachines/restart/action
- Microsoft.Network/networkInterfaces/read
- Microsoft.Network/virtualNetworks/subnets/join/action
Assignable Scopes:
- /subscriptions/{subscription-id}/resourceGroups/{resource-group}
After defining the role in Azure AD, you can assign it to users or groups within your organization. This role can then be applied across your Azure Stack Hub environment, and the users assigned with this role will be able to perform the tasks as per the permissions granted.
Considerations for Custom Roles:
- Least Privilege Principle: Always adhere to the least privilege principle, giving users the minimum level of access necessary for their tasks.
- Role Testing: It’s important to test new custom roles to ensure they provide the correct access and do not impede the role assignee’s ability to carry out their tasks.
- Role Management: Keep track of who has been assigned custom roles, and regularly review and update the roles as necessary.
Custom roles provide the flexibility required for nuanced access control without compromising on security. In the context of Azure Stack Hub, administrators can leverage this feature to tailor access according to the operational needs of individuals and teams, enforcing appropriate boundaries and controls while enabling efficient cloud operations.
Practice Test with Explanation
True or False: Custom roles in Azure AD can be created only using Azure PowerShell.

- Description
- All of the above
Answer: All of the above
Explanation: Custom roles in Azure AD require permissions, assignable scopes, and a description as part of their definition.
True or False: Custom roles can be assigned at the subscription, resource group, and resource levels in Azure Stack Hub.
- True
- False
Answer: True
Explanation: Custom roles can be assigned at different levels, including subscription, resource group, and even at the individual resource level for fine-grained access control.
How are custom roles published in Azure AD for Azure Stack Hub?
- By creating a role assignment
- By submitting a request to Azure support
- By saving the role definition
- By deploying a template
Answer: By saving the role definition
Explanation: Custom roles are published when you save the role definition within Azure AD.
True or False: Once a custom role is defined in Azure AD, it can be used across multiple Azure Stack Hubs without redefinition.
- True
- False
Answer: True
Explanation: Custom roles, once defined, can be used across multiple Azure Stack Hubs as long as the role has been defined at the directory level and the scope of the assignment includes the relevant Azure Stack Hubs.
Which Azure component is used to define a custom role for delegating Azure Stack Hub management tasks?
- Azure Resource Manager
- Azure Service Fabric
- Azure Storage
- Azure Active Directory
Answer: Azure Resource Manager
Explanation: Azure Resource Manager is used for creating, updating, and managing custom roles for Azure resources, including Azure Stack Hub management tasks.
True or False: A maximum of 500 custom roles can be created in a single Azure tenant.
- True
- False
Answer: True
Explanation: An Azure AD tenant has a limit of 500 custom roles that can be defined and used for different purposes, including the management of Azure Stack Hub.
Which of the following can be specified when creating a custom role in Azure Active Directory?
- Application permissions
- Delegated permissions
- Resource actions
- A and C
- All of the above
Answer: All of the above
Explanation: When creating a custom role in Azure Active Directory, you can specify application permissions, delegated permissions, and resource actions that define the role’s capabilities.
True or False: Azure Stack Hub supports the use of built-in roles for management tasks without any customization.
- True
- False
Answer: True
Explanation: Azure Stack Hub does support using built-in roles for management tasks, thus not requiring customization for basic use cases. Custom roles are for more granular and specific management tasks.
In Azure Stack Hub, what is the effect of assigning a user a custom role with very limited permissions?
- The user can manage all aspects of Azure Stack Hub.
- The user has elevated privileges in Azure Stack Hub.
- The user has restricted access based on their specific assigned role.
- The user cannot interact with Azure Stack Hub at all.
Answer: The user has restricted access based on their specific assigned role.
Explanation: Assigning a custom role with limited permissions to a user in Azure Stack Hub will restrict their access and capabilities to only those defined by the role.
True or False: To create a custom role in Azure AD, one must be assigned the Owner or User Access Administrator role at the desired scope.
- True
- False
Answer: True
Explanation: To create a custom role, a user must have sufficient permissions, which typically requires being assigned the Owner or User Access Administrator role at the designated scope.
When should you consider using a custom role instead of a built-in role in Azure Stack Hub?
- When specific permissions are required that are not covered by built-in roles
- When you want to simplify management by using existing roles
- When built-in roles offer too much access
- A and C
- All of the above
Answer: A and C
Explanation: Custom roles should be used when specific permissions are needed that built-in roles do not cover or when built-in roles provide broader access than necessary.
