Your company hosts a web application in Azure, and makes use of Azure Pipelines for managing the build and release of the application.
When stakeholders report that system performance has been adversely affected by the most recent releases, you configure alerts in Azure Monitor.
You are informed that new releases must satisfy specified performance baseline conditions in the staging environment before they can be deployed to production.
You need to make sure that releases not satisfying the performance baseline are prevented from being deployed.
Which of the following actions should you take?

  1. You should make use of a branch control check.
  2. You should make use of an alert trigger.
  3. You should make use of a gate.
  4. You should make use of an approval check.

Answer(s): C

Explanation:

Scenarios and use cases for gates include:
Quality validation. Query metrics from tests on the build artifacts such as pass rate or code coverage and deploy only if they are within required thresholds.
Use Quality Gates to integrate monitoring into your pre-deployment or post-deployment. This ensures that you are meeting the key health/performance metrics (KPIs) as your applications move from dev to production and any differences in the infrastructure environment or scale is not negatively impacting your KPIs.
Note: Gates allow automatic collection of health signals from external services, and then promote the release when all the signals are successful at the same time or stop the deployment on timeout. Typically, gates are used in connection with incident management, problem management, change management, monitoring, and external approval systems.

You need to consider the underlined segment to establish whether it is accurate.
To deploy an application to a number of Azure virtual machines, you should create a universal group. Select ‘No adjustment required’ if the underlined segment is accurate. If the underlined segment is inaccurate, select the accurate option.

  1. No adjustment required.
  2. security
  3. deployment
  4. resource

Answer(s): C

Explanation:

When authoring an Azure Pipelines or TFS Release pipeline, you can specify the deployment targets for a job using a deployment group.
If the target machines are Azure VMs, you can quickly and easily prepare them by installing the Azure Pipelines Agent Azure VM extension on each of the VMs, or by using the Azure Resource Group Deployment task in your release pipeline to create a deployment group dynamically.

DRAG DROP (Drag and Drop is not supported)
You are preparing to deploy an Azure resource group via Terraform.
To achieve your goal, you have to install the necessary frameworks.
Which of the following are the frameworks you should use? Answer by dragging the correct options from the list to the answer area.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



You can use the combination of Terraform and Yeoman. Terraform is a tool for creating infrastructure on Azure. Yeoman makes it easy to create Terraform modules.

Terratest provides a collection of helper functions and patterns for common infrastructure testing tasks, like making HTTP requests and using SSH to access a specific virtual machine. The following list describes some of the major advantages of using Terratest:
-Convenient helpers to check infrastructure - This feature is useful when you want to verify your real infrastructure in the real environment.
-Organized folder structure - Your test cases are organized clearly and follow the standard Terraform module folder structure.

Test cases are written in Go - Many developers who use Terraform are Go developers. If you're a Go developer, you don't have to learn another programming
-language to use Terratest.
-Extensible infrastructure - You can extend additional functions on top of Terratest, including Azure-specific features.

You intend to make use of Azure Artifacts to share packages that you wrote, tested, validated, and deployed. You want to use a solitary feed to release several builds of each package. You have to make sure that the release of packages that are in development is restricted.
Which of the following actions should you take?

  1. You should make use of static code analysis.
  2. You should make use of views.
  3. You should make use of dynamic code analysis.
  4. You should make use of upstream sources.

Answer(s): B
