This AZ-400 practice question tests your understanding of design and implement build and release pipelines. 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.
You have a multi-stage YAML pipeline that deploys to a Linux-based Azure App Service. The pipeline uses a 'Deploy to Azure App Service' task. You need to ensure that the deployment uses the Kudu REST API with ZIP deployment. Which value should you set for the 'packageForLinux' task input?
Set 'enableCustomDeployment' to true
Why wrong: This enables custom deployment scripts, not specifically ZIP deployment via Kudu for Linux.
Set 'useWebDeploy' to false
Why wrong: This disables Web Deploy, but does not enable ZIP deployment for Linux.
Set 'enableKuduDeploy' to true
Why wrong: There is no such input 'enableKuduDeploy' in the Azure Web App task.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Set 'packageForLinux' to true
The 'packageForLinux' input must be set to 'true' to force the 'Deploy to Azure App Service' task to use the Kudu REST API with ZIP deployment when targeting a Linux-based Azure App Service. This is required because Linux App Services do not support WebDeploy (MSDeploy) and rely on the Kudu endpoint for ZIP-based deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Set 'enableCustomDeployment' to true
Why it's wrong here
This enables custom deployment scripts, not specifically ZIP deployment via Kudu for Linux.
Set 'useWebDeploy' to false
Why it's wrong here
This disables Web Deploy, but does not enable ZIP deployment for Linux.
Set 'enableKuduDeploy' to true
Why it's wrong here
There is no such input 'enableKuduDeploy' in the Azure Web App task.
Option-by-option analysis
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-400 exam frequently reuses these exact scenarios with slightly different constraints.
Why this is wrong here
This enables custom deployment scripts, not specifically ZIP deployment via Kudu for Linux.
Why this is wrong here
This disables Web Deploy, but does not enable ZIP deployment for Linux.
Why this is wrong here
There is no such input 'enableKuduDeploy' in the Azure Web App task.

Common exam traps
The trap here is that candidates confuse the 'packageForLinux' input with a generic 'enableKudu' switch, not realizing that Kudu is the underlying mechanism for ZIP deployment on Linux and that this specific input is required to activate it.
Detailed technical explanation
Under the hood, when 'packageForLinux' is set to true, the task constructs a ZIP archive of the deployment package and sends it to the Kudu endpoint at 'https://<app-name>.scm.azurewebsites.net/api/zipdeploy' using HTTP PUT. This is distinct from the Windows App Service path, which defaults to WebDeploy (MSDeploy) and uses the 'msdeploy' protocol. A subtle behavior is that if you omit 'packageForLinux' or set it to false on a Linux App Service, the task may fall back to a slower, less reliable deployment method or fail entirely.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
