- A
Create an Azure Compute Gallery
This provides a managed place to store, version, and share VM images across regions.
- B
Create an image definition and image version
These objects support versioned image publishing and controlled replication to target regions.
- C
Capture the VM as a single managed image and copy it manually to each region
Why wrong: A managed image is not the best fit for versioned, multi-region publishing with centralized lifecycle control.
- D
Use an availability set to preserve the image
Why wrong: Availability sets improve VM resiliency, but they do not store or distribute reusable images.
- E
Take a snapshot of the OS disk and deploy VMs directly from the snapshot
Why wrong: A snapshot is a disk point-in-time copy, not a versioned image distribution mechanism for multiple regions.
AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A platform team has a generalized VM image that must be published to East US and West Europe today and patched later without overwriting the original build. They want Azure to keep version history and replicate the image to both regions. Which two actions or resources should they use? Select two.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create an Azure Compute Gallery
Azure Compute Gallery (formerly Shared Image Gallery) allows you to store and manage VM image versions, including version history, and replicate them across multiple Azure regions. By creating an image definition and image version within the gallery, you can publish the generalized VM image to East US and West Europe today, and later create a new image version for patching without overwriting the original build, preserving the version history.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Capture the VM as a single managed image and copy it manually to each region
Why it's wrong here
A managed image is not the best fit for versioned, multi-region publishing with centralized lifecycle control.
- ✗
Use an availability set to preserve the image
Why it's wrong here
Availability sets improve VM resiliency, but they do not store or distribute reusable images.
When this WOULD be correct
In a question asking how to ensure high availability for a set of VMs running the same application, such as a web tier, where you need to protect against hardware failures and planned maintenance within a single region.
- ✗
Take a snapshot of the OS disk and deploy VMs directly from the snapshot
Why it's wrong here
A snapshot is a disk point-in-time copy, not a versioned image distribution mechanism for multiple regions.
When this WOULD be correct
A question asks for a quick, one-off backup of a single VM's OS disk to be used for disaster recovery in the same region, with no need for versioning or multi-region replication. The snapshot can be used to create a new VM in the same region.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Create an Azure Compute GalleryCorrect answer▾
Why this is correct
This provides a managed place to store, version, and share VM images across regions.
✗Use an availability set to preserve the imageWrong answer — click to see why▾
Why this is wrong here
An availability set is used to distribute VMs across fault domains and update domains for high availability, not for preserving or replicating VM images across regions.
★ When this WOULD be the correct answer
In a question asking how to ensure high availability for a set of VMs running the same application, such as a web tier, where you need to protect against hardware failures and planned maintenance within a single region.
Why candidates choose this
Candidates may confuse availability sets with image management or replication, thinking that 'preserving' an image relates to availability rather than versioning and distribution.
✗Take a snapshot of the OS disk and deploy VMs directly from the snapshotWrong answer — click to see why▾
Why this is wrong here
Snapshots capture a point-in-time copy of a disk but do not support versioning, replication across regions, or shared image management. Deploying VMs directly from snapshots lacks the centralized version history and automated replication provided by Azure Compute Gallery.
★ When this WOULD be the correct answer
A question asks for a quick, one-off backup of a single VM's OS disk to be used for disaster recovery in the same region, with no need for versioning or multi-region replication. The snapshot can be used to create a new VM in the same region.
Why candidates choose this
Candidates may think snapshots are a simple way to capture and reuse an image, but they overlook the need for version history and cross-region replication, which are not supported by snapshots.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a single managed image (Option C) with the Azure Compute Gallery’s image version, not realizing that a managed image lacks version history and automated multi-region replication, which are key requirements for this scenario.
Detailed technical explanation
How to think about this question
Azure Compute Gallery uses a hierarchical resource model: a gallery contains image definitions (which specify the OS type, publisher, offer, SKU, and regional replication settings), and each image definition contains multiple image versions (e.g., 1.0.0, 1.0.1). When you replicate an image version to multiple regions, Azure automatically copies the underlying managed image disks to each target region using Azure’s storage replication, ensuring low-latency deployment. A real-world scenario is a DevOps pipeline that creates a new image version for each patch cycle, allowing rollback to a previous version if needed, while the original build remains untouched.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
