See the solution below in explanation.
Explanation:
To configure a virtual machine template in your DevTest Labs environment namedaz400-38443478-dtl1with Windows Server 2016 Datacenter that includes the Selenium tooland the Google Chrome browser, follow these steps:
* Create a Custom Image with Windows Server 2016 Datacenter:
* In the Azure Portal, go to your DevTest Labaz400-38443478-dtl1.
* Navigate toConfiguration and policies>Custom images.
* Use an existing VM or create a new one with Windows Server 2016 Datacenter.
* After setting up the VM, capture it to create a custom image1.
* Install Selenium and Google Chrome on the VM:
* Connect to the VM via RDP.
* Download and install the Selenium WebDriver for your preferred programming language from the official Selenium website2.
* For Google Chrome, download the offline installer from the official website and install it on the VM3.
* Generalize the VM:
* Run thesysprepcommand to generalize the VM, which prepares it to be used as a template.
* Shutdown the VM aftersysprepcompletes.
* Capture the Generalized VM to Create a Template:
* In the Azure Portal, navigate to the VM and selectCapture.
* Provide the required details and create the image.
* Add Selenium and Google Chrome Artifacts to the Template:
* Go back to the DevTest Labaz400-38443478-dtl1.
* SelectArtifactsand add Selenium and Google Chrome artifacts to the template.
* Ensure these artifacts are configured to install during the VM creation process.
* Create VMs from the Template:
* Now, when youcreate a new VM in the DevTest Lab, select the custom image you created.
* The VM will be provisioned with Windows Server 2016 Datacenter, and the Selenium tool and Google Chrome browser will be installed automatically.
By following these steps, you can ensure that all virtual machines created from this template in your DevTest Lab will have the required operating system, tools, and browser installed. Remember to replace placeholder names with the actual names of your resources where necessary.

Squash merging is a merge option that allows you to condense the Git history of topic branches when you complete a pull request. Instead of each commit on the topic branchbeing added to the history of the defaultbranch, a squash merge takes all the file changes and adds them to a single new commit on the default branch.
A simple way to think about this is that squash merge gives you just the file changes, and a regular merge gives you the file changes and the commit history.
Note: Squash merging keeps your default branch histories clean and easy to follow without demanding any workflow changes on your team. Contributors to the topic branch work how they want in the topic branch, and the default branches keep a linear history through the use of squash merges. The commit history of a master branch updated with squash merges will have one commit for each merged branch. You can step through this history commit by commit to find out exactly when work was done.
