Interview Questions
What does an Event Hubs resource provider in Azure Stack Hub do?
An Event Hubs resource provider brings the fully managed, real-time data ingestion capabilities of Azure Event Hubs into Azure Stack Hub. It enables the development of hybrid event-based solutions using the same Azure SDKs.
What are some of the prerequisites for deploying an Event Hubs resource provider?
Some prerequisites include a Azure Stack Hub integrated system, PowerShell modules for Azure Stack Hub installed, and availability of a service principal in Azure AD.
Is it necessary to connect Azure Stack with public Azure to use Event Hubs?
No, with the Event Hubs resource provider deployed on your Azure Stack Hub, you can build applications that leverage Event Hubs functionality without the need to connect to Azure.
How do you verify the Event Hubs resource provider deployment?
You can verify the deployment from the Azure Stack Hub administrator portal. The deployment should show as successful in both Resource Providers and in the regional management scale unit.
What happens when you deploy the Event Hubs resource provider?
Deploying the Event Hubs resource provider creates a new hosting server and the Event Hubs service on the Azure Stack Hub.
How do you scale out the Event Hubs resource provider if more capacity is needed?
You can scale out the Event Hubs resource provider by deploying additional Event Hubs hosting servers on new virtual machines.
What is an Event Hubs namespace?
An Event Hubs namespace is a scoping container for all Event Hubs that you create. Each Event Hubs namespace corresponds to a single Azure Stack Hub service plan.
How can you manage Event Hubs namespaces after the resource provider is deployed?
Once the resource provider is deployed, you can manage Event Hubs namespaces the same way you manage other types of resources in Azure Stack Hub, using the Azure Stack Hub administrator portal, user portal, or the Azure Stack Hub API.
What is necessary to do before installing an Event Hubs resource provider?
Before installing an Event Hubs resource provider, you need to register an Azure Active Directory application and create a service principal for it.
How should the app secret for the Azure Active Directory app be saved?
The app secret should be saved in a SecureString PowerShell object, which is used when deploying the Event Hubs resource provider.
What is done as part of the post-deployment configuration for the Event Hubs resource provider?
The post-deployment configuration includes obtaining the Active Directory tenant Id, registering the resource provider with Azure Stack, and verifying the successful deployment of the resource provider.
What are the core components of the Event Hubs resource provider?
The core components of the Event Hubs resource provider are the resource provider VM, Event Hubs namespaces and the Event Hubs service.
How can you delete an Event Hubs resource provider?
You can delete the Event Hubs resource provider by running the uninstall script in PowerShell. However, make sure to first delete any resources that depend on the provider.
Can Event Hubs be used to ingest massive amounts of data into Azure Stack Hub?
Yes, Event Hubs is designed for the high-speed ingestion of big data, capable of handling millions of events per second, and can be used for analytics pipelines, IoT, telemetry and more.
Is it possible to replicate data across Event Hubs in different regions?
No, Azure Stack Hub’s Event Hubs does not support cross-region replication. You would need to manage any replication of data across regions yourself.
