Tutorial / Cram Notes
Understanding the correct Azure Stack Hub environment to set up is crucial when preparing for the AZ-600: Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam. This certification test assesses your ability to operate a hybrid cloud environment using Azure Stack Hub, which includes planning, deployment, package management, and maintenance tasks. When studying for the exam, it becomes necessary to familiarize oneself with various scenarios that could dictate the type of environment to deploy.
Scenario 1: Disconnected Environment
In some situations, you may need to operate Azure Stack Hub in a disconnected or partially connected environment. This is typical for scenarios where network connectivity is limited due to security requirements or infrastructural limitations.
Example:
- A military site has no consistent connectivity to the Azure public cloud due to security policies.
- A research station in a remote location with limited internet bandwidth.
For these environments, you would use the Azure Stack Hub in a disconnected mode. In this mode, you must manually download and import marketplace items, updates, and hotfixes to the Azure Stack Hub.
Azure Stack Hub Disconnected Mode:
| Feature | Operation in Disconnected Mode |
|---|---|
| MarketPlace Syndication | Manually import items |
| Usage Data | Manual upload process (if desired) |
| Updates | Download externally, transfer, and apply manually |
Scenario 2: ADFS Environment
Another scenario is when an organization wants to use Active Directory Federation Services (ADFS) for identity management instead of Azure Active Directory (Azure AD).
Example:
- A company with stringent control over identities and authentication, preferring on-premises identity management.
For this type of environment, Azure Stack Hub needs to be configured with ADFS. This provides an environment where the organization maintains control over identities.
Azure Stack Hub ADFS vs. Azure AD Environment:
| Feature | Azure AD Environment | ADFS Environment |
|---|---|---|
| Identity Source | Azure AD | On-Premises AD |
| Federated Apps | Supported | Supported |
| Multi-Tenancy | Supported | Limited |
Scenario 3: Multi-Tenant Environment
Some enterprises and service providers require a multi-tenant environment to support multiple organizations or departments within a single Azure Stack Hub deployment.
Example:
- Hosting providers offering services to various small businesses.
- A large enterprise hosting internal departments or subdivisions.
For this, you would need to configure Azure Stack Hub to support multi-tenancy, which includes setting up offers, plans, quotas, and delegated providers.
Multi-Tenant Configuration:
| Element | Consideration When Configuring |
|---|---|
| Offers | Creation of offers tailored to tenant needs |
| Plans | Packages of services defining what resources are available |
| Quotas | Limits set per tenant to avoid resource monopolization |
| Delegated Providers | Enable service providers to manage resources for tenants |
Scenario 4: Development Environment
In circumstances where Azure Stack Hub is being used for development and testing, the approach might be lightweight compared to a full production deployment.
Example:
- A development team building Azure hybrid applications.
- A test lab for validating hybrid cloud deployments.
Azure Stack Development Kit (ASDK) can be used here, which is a free, single-node instance of Azure Stack Hub that can be used for development and testing purposes.
Azure Stack Development Kit (ASDK):
| Component | ASDK Characteristics |
|---|---|
| Scale | Single-node only |
| Usage | Non-production, testing, and development |
| Cost | Free to install and use |
| Availability | Requires internet connection during the setup |
When it comes to the AZ-600 exam, it’s important to understand the differences between these environments, the decision points that guide their selection, and how they impact overall system configuration and operation. Familiarity with the configuration specifics, based on the given scenario, is key to accomplishing daily tasks as an Azure Stack Hub operator and successfully passing the certification exam.
Practice Test with Explanation

- d) Pricing consistency
a) API consistency
Explanation: Azure Stack Hub offers API consistency with Azure, ensuring that cloud services and applications can run seamlessly across both Azure and Azure Stack Hub environments.
Single Select: In the context of Azure Stack Hub, what does the acronym WAG stand for?
- a) Windows Application Gateway
- b) Web Application Gateway
- c) Wide Area Gateway
- d) Web Application Gateway
d) Web Application Gateway
Explanation: In Azure Stack Hub, WAG stands for Web Application Gateway, which is a service that provides application layer load balancing and security features.
Multiple Select: Which of the following services can be offered on an Azure Stack Hub integrated system?
- a) SQL Database services
- b) Machine Learning services
- c) Kubernetes services
- d) Virtual Network services
a) SQL Database services, c) Kubernetes services, d) Virtual Network services
Explanation: Azure Stack Hub supports offering various services, including SQL Database services through SQL resource providers, Kubernetes services with Azure Kubernetes Service (AKS) on Azure Stack Hub, and Virtual Network services for networking capabilities. Machine Learning services are not natively supported as of the knowledge cutoff date.
True/False: It is mandatory to use Azure Active Directory (Azure AD) for identity management on Azure Stack Hub.
False
Explanation: While Azure AD is a common choice for identity management, Azure Stack Hub also supports the use of Active Directory Federation Services (AD FS) for scenarios where Azure AD cannot be used.
Single Select: Azure Stack Hub supports which deployment model for creating resources?
- a) Classic
- b) ARM (Azure Resource Manager)
- c) Both Classic and ARM
- d) None of the above
b) ARM (Azure Resource Manager)
Explanation: Azure Stack Hub only supports the ARM (Azure Resource Manager) deployment model for creating and managing resources. The Classic model is not supported.
