Question 2

You have a multi-tier application. The front end of the application is hosted in Azure App Service.
You need to identify the average load times of the application pages. What should you use?

Accepted Answer

Application Insights will tell you about any performance issues and exceptions, and help you find and diagnose the root causes.
Application Insights can monitor both Java and ASP.NET web applications and services, WCF services. They can be hosted on-premises, on virtual machines, or
as Microsoft Azure websites.
On the client side, Application Insights can take telemetry from web pages and a wide variety of devices including iOS, Android, and Windows Store apps.

Question 3

Your company has a hybrid cloud between Azure and Azure Stack.
The company uses Azure DevOps for its CI/CD pipelines. Some applications are built by using Erlang and Hack.
You need to ensure that Erlang and Hack are supported as part of the build strategy across the hybrid cloud. The solution must minimize management overhead.
What should you use to execute the build pipeline?

Accepted Answer

Azure Stack offers virtual machines (VMs) as one type of an on-demand, scalable computing resource. You can choose a VM when you need more control over
the computing environment.

Question 5

DRAG DROP - (Topic 4)
You need to recommend project metrics for dashboards in Azure DevOps.
Which chart widgets should you recommend for each metric? To answer, drag the appropriate chart widgets to the correct metrics. Each chart widget 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.

Accepted Answer

Box 1: Lead time
Lead time measures the total time elapsed from the creation of work items to their completion.
Box 2: Cycle time
Cycle time measures the time it takes for your team to complete work items once they begin actively working on them.
Box 3: Burndown
Burndown charts focus on remaining work within a specific time period.

Your company has a project in Azure DevOps for a new web application. You need to ensure that when code is checked in, a build runs automatically.
Solution: From the Pre-deployment conditions settings of the release pipeline, you select Batch changes while a build is in progress.
Does this meet the goal?

Accepted Answer

Use a Pull request trigger.
Note: Batch changes
Select this check box if you have a lot of team members uploading changes often and you want to reduce the number of builds you are running. If you select this
option, when a build is running, the system waits until the build is completed and then queues another build of all changes that have not yet been built.

Question 10

You have a GitHub repository that contains workflows. The workflows contain steps that execute predefined actions. Each action has one or more versions.
You need to request the specific version of an action to execute.
Which three attributes can you use to identify the version? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

Accepted Answer

https://docs.github.com/en/actions/using-workflows/workflow-syntax-for- github-actions
"We strongly recommend that you include the version of the action you are using by specifying a Git ref, SHA, or Docker tag. If you don't specify a version, it could
break your workflows or cause unexpected behavior when the action owner publishes an update. Using the commit SHA of a released action version is the safest
for stability and security. If the action publishes major version tags, you should expect to receive critical fixes and security patches while still retaining compatibility.
Note that this behavior is at the discretion of the action's author. Using the default branch of an action may be convenient, but if someone releases a new major
version with a breaking change, your workflow could break."
