- A
Each machine in a deployment group must have the Azure Pipelines agent installed.
Agent is required to receive tasks.
- B
Deployment groups can only be used with Windows-based machines.
Why wrong: Deployment groups support multiple OS.
- C
Deployment groups allow you to deploy an application to multiple machines in a rolling fashion.
Rolling deployments are a key use case.
- D
Deployment groups can be used in classic release pipelines.
Classic release pipelines support deployment groups.
- E
Deployment groups are tied to a specific environment.
Why wrong: Deployment groups are separate from environments.
Question 580 of 928
Deployment Groups in Azure Pipelines
This AZ-400 practice question tests your understanding of design and implement build and release pipelines. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 are true about using deployment groups in Azure Pipelines? (Choose 3)
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
✓
Each machine in a deployment group must have the Azure Pipelines agent installed.
Option A is correct because each target machine in a deployment group requires the Azure Pipelines agent (either the Windows or Linux agent) to be installed and configured. The agent is responsible for executing the deployment tasks on that machine, and without it, the deployment group cannot communicate with or deploy to the machine.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse deployment groups with environments, assuming they are the same concept, but deployment groups are a legacy feature for multi-machine deployments while environments are a newer, more flexible abstraction that supports Kubernetes, virtual machines, and other resources.
Detailed technical explanation
How to think about this question
Deployment groups use a registration script that installs the Azure Pipelines agent on each machine and registers it with the group via a personal access token (PAT). The agent then listens for deployment jobs, allowing rolling deployments by targeting a subset of machines in the group using tags and parallelism settings. This mechanism is distinct from environment-level approvals and checks, which are applied at the environment scope, not the deployment group scope.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
