QUESTION 1
DRAG DROP
You are configuring the settings of a new Git repository in Azure Repos.
You need to ensure that pull requests in a branch meet the following criteria before they are merged:
1.
Committed code must compile successfully.
2.
Pull requests must have a Quality Gate status of Passed in SonarCloud.
Which policy type should you configure for each requirement? To answer, drag the appropriate policy types to the
correct requirements. Each policy type may be used once, more than once, or not at all. You may need to drag the split
bar
between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Box 1: A check-in policy
Administrators of Team Foundation version control can add check-in policy requirements. These check-in policies
require the user to take actions when they conduct a check-in to source control.
By default, the following check-in policy types are available:
1.
Builds Requires that the last build was successful before a check-in.
2.
Code Analysis Requires that code analysis is run before check-in.
3.
Work Items Requires that one or more work items be associated with the check-in.

QUESTION 2
HOTSPOT
You need to deploy Azure Kubernetes Service (AKS) to host an application. The solution must meet the following
requirements:
1.
Containers must only be published internally.
2.
AKS clusters must be able to create and manage containers in Azure.
What should you use for each requirement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Box 1: Azure Container Registry Azure services like Azure Container Registry (ACR) and Azure Container Instances
(ACI) can be used and connected from independent container orchestrators like kubernetes (k8s). You can set up a
custom ACR and connect it to an existing k8s cluster to ensure images will be pulled from the private container registry
instead of the public docker hub.
Box 2: An Azure service principal When you\\’re using Azure Container Registry (ACR) with Azure Kubernetes Service
(AKS), an authentication mechanism needs to be established. You can set up AKS and ACR integration during the initial
creation of your AKS cluster. To allow an AKS cluster to interact with ACR, an Azure Active Directory service principal is
used.
