Quick Answer
The answer is that apps in the same App Service plan share compute resources even when deployed across different resource groups. This is correct because the App Service plan itself defines the underlying virtual machines, memory, and CPU that all apps within it consume, regardless of which resource group contains each app. The resource group is merely a logical container for management and billing, not a boundary for compute allocation. On the AZ-104 exam, this concept tests your understanding that the plan is the unit of scale and cost, not the resource group—a common trap is assuming that separate resource groups imply separate infrastructure. Remember the mnemonic: “Plan pools power; resource groups just organize.”
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.
Which three of the following statements about Azure App Service plans are correct? (Choose three.)
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
Apps in the same App Service plan share the same compute resources, even if they are in different resource groups.
Apps in the same App Service plan share the same compute resources (VMs, memory, CPU) because the plan defines the underlying infrastructure. This is true even if the apps are in different resource groups, as the plan is the boundary for resource allocation, not the resource group.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume apps must be in the same resource group to share resources, but Azure App Service plans are resource-group-agnostic for compute sharing, and they also mistakenly think Free/Shared tiers include custom domains and SSL, which they do not.
Detailed technical explanation
How to think about this question
Under the hood, an App Service plan maps to a set of virtual machine instances (worker nodes) in a specific region. All apps in the plan are deployed to these same VMs, sharing memory and CPU. When you scale out the plan (increase instance count), all apps automatically benefit from the additional instances. However, scaling up (changing tier) may trigger a migration of the plan to a different VM SKU, which can cause a brief outage if the tier change requires a new deployment.
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
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
