AZ-400 Infrastructure as Code 2

Question 1

In Azure Bicep, what is the purpose of the `@description` decorator?

Accepted Answer

Adds human-readable documentation to parameters and outputs

Answer

The `@description` decorator adds metadata documentation strings to parameters, variables, and outputs in Bicep files.

Question 2

Which Terraform command is used to preview infrastructure changes without applying them?

Accepted Answer

terraform plan

Answer

`terraform plan` generates an execution plan showing what changes Terraform will make without actually applying them.

Question 3

When using Azure Resource Manager (ARM) templates, what does the `dependsOn` property control?

Accepted Answer

Explicit resource deployment ordering when implicit dependencies are insufficient

Answer

`dependsOn` explicitly defines deployment dependencies so ARM waits for specified resources to finish before deploying the dependent resource.

Question 4

What is the primary benefit of using Terraform workspaces in a multi-environment IaC strategy?

Accepted Answer

They enable managing multiple distinct state files from the same configuration

Answer

Terraform workspaces maintain separate state files for each workspace, letting the same configuration manage dev, staging, and prod environments independently.

Question 5

In Azure DevOps pipelines, which built-in variable contains the source branch name that triggered the pipeline?

Accepted Answer

$(Build.SourceBranchName)

Answer

`$(Build.SourceBranchName)` contains the branch or tag name (without refs/heads/) that triggered the current pipeline run.
