Question 1

A Bicep template deployment fails with 'The resource already exists and was not created by this deployment.' Which property should you add to handle existing resources?

Accepted Answer

existing keyword in Bicep resource declaration

Answer

The `existing` keyword in Bicep allows you to reference a resource that already exists without attempting to create or update it.

Question 2

Your organization wants to enforce that all Azure resource groups created via IaC have required tags. Which combination achieves this with least effort?

Accepted Answer

Azure Policy with Append effect + Deny for missing required tags

Answer

Azure Policy with Append effect adds missing tags automatically and a Deny policy blocks deployments missing required tags, enforcing compliance at the platform level.

Question 3

Which Terraform command shows the execution plan without applying any changes?

Accepted Answer

terraform plan

Answer

`terraform plan` generates and displays an execution plan showing what actions Terraform will take without making any changes.

Question 4

A package in Azure Artifacts is marked as 'deprecated'. What effect does this have on pipeline builds?

Accepted Answer

Consumers see a warning but builds continue unless the feed blocks deprecated packages

Answer

Marking a package as deprecated generates a warning for consumers but does not block builds by itself; feed administrators must enable additional policies to block deprecated packages.

Question 5

You want to use the same Bicep module for both development and production deployments but with different parameter values. What is the recommended approach?

Accepted Answer

Use Bicep parameter files (.bicepparam) per environment

Answer

Bicep parameter files (.bicepparam) allow environment-specific parameter values to be stored separately and referenced during deployment without duplicating the module.
