NEW QUESTION # 169
You have an Azure Resource Manager template that deploys a multi-tier application.
You need to prevent the user who performs the deployment from viewing the account credentials and connection strings used by the application.
What should you use?

A. an Azure Storage table
B. a Web.config file
C. an Azure Resource Manager parameter file
D. an Appsettings.json files
E. Azure Key Vault

Answer: E

Explanation:
When you need to pass a secure value (like a password) as a parameter during deployment, you can retrieve the value from an Azure Key Vault. You retrieve the value by referencing the key vault and secret in your parameter file. The value is never exposed because you only reference its key vault ID. The key vault can exist in a different subscription than the resource group you are deploying to.

You need to analyze and monitor the code quality of the Java solution.
Which task types should you add to the build pipeline?

A. Gulp
B. Octopus
C. Gradle
D. Chef

Answer: C

Explanation:
SonarQube is a set of static analyzers that can be used to identify areas of improvement in your code. It allows you to analyze the technical debt in your project and keep track of it in the future. With Maven and Gradle build tasks, you can run SonarQube analysis with minimal setup in a new or existing Azure DevOps Services build task.
