Tutorial / Cram Notes
Azure Stack Hub is an extension of Azure, bringing the agility and innovation of cloud computing to on-premises environments. When setting up Azure Stack Hub, it is crucial to validate that your identity provider and network configurations meet the necessary prerequisites for a successful deployment. The Azure Stack Hub Readiness Checker tool is designed to assist with this validation process.
Validating Identity Providers with Azure Stack Hub Readiness Checker
Before deploying Azure Stack Hub, you need to ensure that your identity provider is configured correctly. Azure Stack Hub supports two types of identity providers:
- Azure Active Directory (Azure AD)
- Active Directory Federation Services (AD FS)
The Readiness Checker tool helps verify that:
- A global admin account is available for Azure AD, or a domain admin account for AD FS.
- The Azure AD tenant is accessible and properly configured.
- The AD FS deployment is reachable and meets the necessary requirements.
Example: Validate Azure AD
To validate Azure AD, run the Readiness Checker tool with the following PowerShell commands:
$creds = Get-Credential
Test-AzureStackIdentity -IdentityProvider “AzureAD” -AzureADTenantName “yourdomain.onmicrosoft.com” -Credential $creds
Replace yourdomain.onmicrosoft.com with your actual Azure AD tenant name. The tool will check for connectivity and proper configuration with Azure AD.
Validating Network Configuration with Azure Stack Hub Readiness Checker
A properly configured network is vital for Azure Stack Hub to function. The Readiness Checker tool verifies:
- The network switch and router configurations comply with the necessary requirements.
- The required ports and URLs are open and reachable.
- Network Time Protocol (NTP) servers are accessible.
- DNS settings are properly configured.
Example: Check Network Prerequisites
To use the Readiness Checker for validating your network, run the following commands in PowerShell:
$region = “local”
$ipAddress = “192.168.100.101”
Test-AzureStackNetwork -Region $region -IPAddress $ipAddress
This example assumes that you have an IP address of 192.168.100.101 that needs to be tested. Provide your actual IP address and the appropriate region.
Results and Troubleshooting
The Azure Stack Hub Readiness Checker tool will provide detailed output regarding the validation process. This information includes:
- Pass/Fail status for each item checked.
- Descriptive error messages if issues are detected.
- Recommendations for how to fix the identified issues.
Here is a simplified example of output that you might see from the tool:
IdentityProvider : AzureAD
ValidationStatus : Passed
Network : Passed
RouterConfig : Passed
PortAvailability : Failed
NTPOpen : Passed
DNSResolution : Passed
In case of a failure, such as PortAvailability : Failed, the tool will suggest the ports that need to be opened and any other necessary actions.
The Azure Stack Hub Readiness Checker tool is essential for pre-deployment validation of identity providers and network configurations. By ensuring that all prerequisites are met, it helps to avoid common deployment issues and lays the groundwork for a successful Azure Stack Hub implementation.
For the most up-to-date information, guidance, and troubleshooting tips, refer to the official Microsoft documentation and make sure to keep the Azure Stack Hub Readiness Checker tool updated to its latest version.
Practice Test with Explanation

The Readiness Checker tool can validate the configuration of both Azure AD and AD FS as identity providers for Azure Stack Hub.
Which component does the Azure Stack Hub Readiness Checker NOT validate?
- A) Network infrastructure
- B) Identity provider
- C) Subscription quotas
- D) Hardware compatibility
C) Subscription quotas
The Azure Stack Hub Readiness Checker tool does not validate subscription quotas; it focuses on aspects like the identity provider, network setup, and hardware compatibility, among others.
T/F: The Azure Stack Hub Readiness Checker tool requires administrative privileges to be run on the system.
- True
To perform its checks effectively, the Azure Stack Hub Readiness Checker tool needs to be run with administrative privileges.
T/F: The Azure Stack Hub Readiness Checker tool is used after the deployment of Azure Stack Hub to ensure everything is running properly.
- False
The Readiness Checker tool is used before the deployment to ensure all prerequisites are met, not after deployment.
What is the purpose of the ‘Network’ check in the Azure Stack Hub Readiness Checker tool?
- A) To verify VM sizes
- B) To validate network infrastructure
- C) To check storage space
- D) To monitor runtime performance
B) To validate network infrastructure
The ‘Network’ check validates the network infrastructure, such as DNS, firewall settings, and ports required for Azure Stack Hub.
How is the Azure Stack Hub Readiness Checker tool executed?
- A) Through Azure Portal
- B) Using PowerShell
- C) Via a web interface
- D) Through Azure CLI
B) Using PowerShell
The Readiness Checker tool is executed using PowerShell scripts from a local machine.
T/F: The Azure Stack Hub Readiness Checker tool can only be run on an Azure Stack Hub integrated system.
- False
The tool can also be run on a local machine or environment that is being prepared for Azure Stack Hub, not just on an integrated system.
Before running the Azure Stack Hub Readiness Checker tool, you must:
