Task 3
You need to ensure that an Azure Web App named az400-38443478-matn supports rolling upgrades The solution must ensure that only 10 percent of users who connect to az400-38443478 main use updated versions of the app. The solution must minimize administrative effort.
To ensure that your Azure Web App named az400-38443478-main supports rolling upgrades and only 10 percent of users connect to the updated version of the app, you can use deployment slots with the following steps:
Create a Deployment Slot:
Navigate to the Azure Portal.
Go to your Web App az400-38443478-main.
Select Deployment slots in the menu.
Click on Add Slot.
Name the slot (e.g., staging) and if needed, clone settings from the production slot.
Configure the Traffic Percentage:
In the Deployment Slots menu, you will see a column for Traffic %.
Set the traffic percentage to 10% for the staging slot1.
This will route only 10% of the traffic to the updated version of the app in the staging slot.
Deploy the Updated App to the Staging Slot:
Deploy your updated application to the staging slot.
Test the application in the staging slot to ensure it's working as expected.
Complete the Rolling Upgrade:
Once you're satisfied with the performance and stability of the app in the staging slot, you can gradually increase the percentage of traffic until you're ready to swap with the production slot.
To swap slots, go to the Deployment slots menu and click on Swap with the production slot.
By using deployment slots, you can achieve rolling upgrades with minimal administrative effort, as it allows you to test the new version on a subset of users before fully releasing it. Remember to adjust the traffic percentage and monitor the application's performance throughout the process.

Task 4
You need to configure a virtual machine template in a DevTest Labs environment named az400-38443478-dtl1. The operating system must be based on Windows Server 2016 Datacenter. Virtual machines created from the DevTest Lab must include the Selenium tool and the Google Chrome browser.
To configure a virtual machine template in your DevTest Labs environment named az400-38443478-dtl1 with Windows Server 2016 Datacenter that includes the Selenium tool and the Google Chrome browser, follow these steps:
Create a Custom Image with Windows Server 2016 Datacenter:
In the Azure Portal, go to your DevTest Lab az400-38443478-dtl1.
Navigate to Configuration 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.
Generalize the VM:
Run the sysprep command to generalize the VM, which prepares it to be used as a template.
Shut down the VM after sysprep completes.
Capture the Generalized VM to Create a Template:
In the Azure Portal, navigate to the VM and select Capture.
Provide the required details and create the image.
Add Selenium and Google Chrome Artifacts to the Template:
Go back to the DevTest Lab az400-38443478-dtl1.
Select Artifacts and 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 you create 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.
