Interview Questions
1. What is Azure Compute Gallery?
Azure Compute Gallery (Shared Image Gallery) is a service that helps you to build structure and distribution of the custom virtual hard disks (VHDs), templates, and more.
2. How many images can a Shared Image Gallery have?
A Shared Image Gallery can contain multiple image definitions, and each image definition can have multiple named versions of an image.
3. What are the three components of the Shared Image Gallery?
The three components of the Shared Image Gallery are the Shared Image Gallery itself, Image Definition, and Image Versions.
4. What is the purpose of Image Definition in Azure Compute Gallery?
Image Definition in Azure Compute Gallery is used to group versions of an image. Image definitions carry information about the image and requirements for using it like OS type, recommended VM size, and more.
5. What does the Image Version contain in Azure Compute Gallery?
Image Version contains an image and manages the distribution of an image. You can have multiple versions of an image per Image Definition.
6. Can you replicate Image Versions across multiple Azure regions?
Yes, you can replicate Image Versions across multiple Azure regions, and you can specify how many replicas you want in each region.
7. What can be the maximum number of replicas of an image version in a region?
The maximum number of replicas of an image version in a region is 10.
8. Can you use PowerShell to manage images in Azure Compute Gallery?
Yes, you can use PowerShell, Azure CLI, or SDKs to manage images in Azure Compute Gallery alongside the Azure portal.
9. How to create a Shared Image Gallery in Azure?
A Shared Image Gallery can be created using the Azure portal, Azure Powershell, Azure CLI, or SDKs. This process involves creating a resource group if it doesn’t already exist, and then using the appropriate commands or instructions to create the gallery.
10. Can you share a Shared Image Gallery with other subscriptions?
Yes, you can share a Shared Image Gallery with other subscriptions by assigning the appropriate role access at the Image Definition level.
11. What’s the minimum and maximum number of versions allowed per image in Shared Image Gallery?
In Shared Image Gallery, the minimum number of versions per image is 1, and the maximum number is 1,000.

To distribute images to Azure Government cloud or China regions, your shared Image must be created within that cloud.
13. What is the use of a replication count in Azure Compute Gallery?
The replication count signifies the number of copies of an image. A higher number of replicas helps in faster allocation of VM during deployment since Azure doesn’t need to copy the image before deploying the VM.
14. Can you update an existing image version in Shared Image Gallery?
No, you cannot update an existing image version in Shared Image Gallery. However, you can create a new image version with the updated content.
15. Can I move Shared Image Gallery, image definition, and image version resources across different resource groups or subscriptions?
