Microsoft Designing and Implementing Microsoft DevOps Solutions Sample Questions (Q150-Q155):

NEW QUESTION # 150
You have an Azure subscription that uses Azure Monitor and contains a Log Analytics workspace.
You have an encryption key.
You need to configure Azure Monitor to use the key to encrypt log data

Answer:

Explanation:

1 - Create an Azure key vault and store the key.
2 - Configure the key vault properties for the cluster.
3 - Grant the system-assigned managed identity Key permissions for the key vault.
4 - Create an Azure Monitor Logs dedicated...
5 - Link the Log Analytics workspace to the cluster...

NEW QUESTION # 151
You plan to deploy a website that will be hosted in two Azure regions.
You need to create an Azure Traffic Manager profile named az40011566895n1-tm in a resource group named RG1lod11566895. The solution must ensure that users will always connect to a copy of the website that is in the same country.
To complete this task, sign in to the Microsoft Azure portal.

Answer:

Explanation:
See solution below.
Explanation:
1. Go to the Azure portal, navigate to Traffic Manager profiles and click on the Add button to create a routing profile.

2. In the Create Traffic Manager profile, enter, or select these settings:Name: az40011566895n1-tmRouting method: GeographicResource group: RG1lod11566895 Note: Traffic Manager profiles can be configured to use the Geographic routing method so that users are directed to specific endpoints (Azure, External or Nested) based on which geographic location their DNS query originates from. This empowers Traffic Manager customers to enable scenarios where knowing a user's geographic region and routing them based on that is important.

NEW QUESTION # 152
You are developing a full Microsoft .NET Framework solution that includes unit tests.
You need to configure SonarQube to perform a code quality validation of the C# code as part of the build pipelines.
Which four tasks should you perform in sequence? To answer, move the appropriate tasks from the list of tasks to the answer area and arrange them in the correct order.

Answer:

Explanation:

References: https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Extension+for+VSTS-TFS

NEW QUESTION # 153
You are configuring Azure Pipelines for three projects in Azure DevOps as shown in the following table.

Which version control system should you recommend for each project? To answer, drag the appropriate version control systems to the correct projects. Each version control system 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.

Answer:

Explanation:

Explanation:
Project1:Git in Azure Repos
Project2: Github Enterprise
GitHub Enterprise is the on-premises version of GitHub.com. GitHub Enterprise includes the same great set of features as GitHub.com but packaged for running on your organization's local network. All repository data is stored on machines that you control, and access is integrated with your organization's authentication system (LDAP, SAML, or CAS).
Project3: Bitbucket cloud
One downside, however, is that Bitubucket does not include support for SVN but this can be easily amended migrating the SVN repos to Git with tools such as SVN Mirror for Bitbucket .
Note: SVN is a centralized version control system.
Incorrect Answers:
Bitbucket:
Bitbucket comes as a distributed version control system based on Git.
Note: A source control system, also called a version control system, allows developers to collaborate on code and track changes. Source control is an essential tool for multi-developer projects.
Our systems support two types of source control: Git (distributed) and Team Foundation Version Control (TFVC). TFVC is a centralized, client-server system. In both Git and TFVC, you can check in files and organize files in folders, branches, and repositories.
