The answer is Azure Marketplace VM images. This is the correct choice because these images are pre-configured virtual machine templates that bundle both an operating system and application software, enabling you to deploy pre-packaged applications from the Azure Marketplace with a single click. On the Microsoft Azure Fundamentals AZ-900 exam, this question tests your understanding of compute options for rapid deployment versus building from scratch—a common trap is confusing these images with Azure App Service, which runs code without full OS control, or with container services like AKS. Remember that “VM images” mean you get the whole virtual machine, OS and app together, ready to launch. A useful memory tip: think of a “pre-packaged meal” versus cooking from raw ingredients—Marketplace VM images are the microwave-ready meal for your Azure compute needs.
AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which Azure compute option lets you run pre-packaged applications from the Azure Marketplace with pre-configured OS and application software?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Marketplace VM images
Azure Marketplace VM images (Option B) are pre-configured virtual machine images that include both an operating system and application software, allowing you to deploy pre-packaged solutions quickly. These images are published by Microsoft, third-party vendors, and the community, and they are directly available from the Azure portal for one-click deployment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Custom Images from Compute Gallery
Why it's wrong here
Custom Images are organization-specific; Marketplace provides pre-configured third-party and Microsoft images.
✓
Azure Marketplace VM images
Why this is correct
Azure Marketplace provides pre-configured VM images with OS and applications ready to deploy.

Read the scenario before looking for a memorised answer.
✗
Azure DevTest Labs formulas
Why it's wrong here
DevTest Labs formulas create VMs from standard images with team configurations; Marketplace provides the pre-built images.
✗
Azure Container Registry base images
Why it's wrong here
Container Registry stores container images; Marketplace provides broader pre-configured VM and solution offerings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Azure Marketplace VM images (pre-packaged, ready-to-deploy) with custom images you create yourself, leading candidates to choose Azure Custom Images from Compute Gallery, which are not pre-packaged from the Marketplace.
Detailed technical explanation
How to think about this question
Azure Marketplace VM images are stored in the Azure Compute Gallery (formerly Shared Image Gallery) and are versioned, allowing you to replicate them across regions for disaster recovery and scale-out scenarios. Each image includes a specific SKU, publisher, and offer, which you can reference in ARM templates or Terraform scripts for automated deployments. A real-world scenario is deploying a pre-configured SQL Server on Windows Server image, which includes the OS, SQL Server binaries, and licensing, reducing setup time from hours to minutes.

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.
