Task 12: Configure Iterations in Project1 for Azure Boards

Step 1: Navigate to Project Settings

In your Azure DevOps Project (Project1), click on the Project settings gear icon in the lower-left corner.

Step 2: Manage Project Iterations (Sprints)

In the Boards section of the Project settings, click Project configuration .

In the left menu, click on Iterations .

Step 3: Add Iterations

Click on the + New child link to add a new iteration under the root node (e.g., Project1).

Enter the following details:

Name: Sprint 1

Leave the start and end dates empty (or set them as needed for your planning).

Click Save and close .

Repeat the process:

Click + New child again.

Name: Sprint 2

Leave the start and end dates empty.

Click Save and close .

Finally, create Sprint 3 with specific dates:

Click + New child .

Name: Sprint 3

Start date: January 1 of next year (e.g., 2026-01-01).

End date: January 31 of next year (e.g., 2026-01-31).

Click Save and close .

Step 4: Assign Iterations to Work Items

With these iterations created, you can now assign them to work items (e.g., tasks, bugs, features) using Azure Boards.

In Boards , click on Work items .

Open any work item.

In the Iteration Path field, select one of your newly created iterations (Sprint 1, Sprint 2, or Sprint 3).

This ensures that work items can be tracked under the appropriate sprint.

Step 1: Log in to the Azure Portal

Go to https://portal.azure.com .

Log in with your Azure account.

Step 2: Create an Azure App Configuration Instance

In the search bar at the top, type “App Configuration” and select App Configuration from the search results.

Click + Create .

Fill in the required fields:

Subscription: Your Azure subscription.

Resource Group: Create a new one or select an existing one.

Name: Provide a globally unique name (for example, myappconfig-instance).

Location: Choose a region close to your application.

Click Review + Create , then Create .

The instance will take a few seconds to deploy.

Step 3: Access the App Configuration Instance

Once the deployment is complete, click Go to resource .

You are now in the App Configuration resource.

Step 4: Enable Feature Management

In the left menu, click on Feature Manager (Preview) .

Click + Add to create a new feature flag.

Step 5: Create the Feature Flag

Provide the following details:

Feature flag name: feature1

Label: (optional)

Description: (optional)

State: Set to Enabled .

Click on the Add filters link if you want to add targeting filters (optional).

Click Save to create the feature flag.

Step 6: Set the Expiration Date for the Feature Flag

In the Feature Manager list, find the newly created feature1 flag.

Click on the three dots (context menu) next to feature1 and select Edit .

In the Edit feature pane, look for the Expiration date setting. If there is no direct UI for expiration date, you can store it as a custom key-value (metadata).

Here’s how to store expiration as metadata:

In the App Configuration left menu, click on Configuration Explorer .

Locate the key: .appconfig.featureflag/feature1.

Click on the key to edit.

Add a new label or add a custom key in the Content type or tags section to store expiration metadata:

Key: expiration

Value: yyyy-MM-dd (set to today + 7 days)

For example, if today is June 4, 2025, set the expiration as 2025-06-11.

Scenario: By default, all releases must remain available for 30 days, except for production releases, which must be kept for 60 days.

Box 1: Set the default retention policy to 30 days

The Global default retention policy sets the default retention values for all the build pipelines. Authors of build pipelines can override these values.

Box 2: Set the stage retention policy to 60 days

You may want to retain more releases that have been deployed to specific stages.

Box 1: A source control system

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.

Box 2: A hosted service

To build and deploy Xcode apps or Xamarin.iOS projects, you ' ll need at least one macOS agent. If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up a self-hosted macOS agent.

Scenario: The investment planning applications suite will include one multi-tier web application and two iOS mobile applications. One mobile application will be used by employees; the other will be used by customers.

Box 1: Get-AzResource

Use the following command to examine the access control mode for all workspaces in the subscription:

PowerShell

Get-Az Resource –Resource Type Microsoft. Operational Insights/workspaces –Expand Properties | for each {s.Name + " : " + $_.Properties.features.enableLogAccessUsingOnlyResourcePermissions

Box 2: -Resource Type

Box 1: rwx

The Log Analytics agent for Linux runs as the omsagent user. To grant > write permission to the omsagent user, run the command setfacl -m u:omsagent:rwx /tmp.

Box 2: /tmp

Deploying DSC to a Linux node uses the /tmp folder.

Unattended config:

The agent can be set up from a script with no human intervention. You must pass --unattended and the answers to all questions.

To configure an agent, it must know the URL to your organization or collection and credentials of someone authorized to set up agents. All other responses are optional.

Scenario: Visual Studio App Center must be used to centralize the reporting of mobile application crashes and device types in use.

In order to use App Center, you need to opt in to the service(s) that you want to use, meaning by default no services are started and you will have to explicitly call each of them when starting the SDK.

Insert the following line to start the SDK in your app ' s App Delete class in the didFinishLaunchingWithOptions method.

MSAppCenter.start( " {Your App Secret} " , withServices: [MSAnalytics.self, MSCrashes.self])

Every request made against a storage service must be authorized, unless the request is for a blob or container resource that has been made available for public or signed access. One option for authorizing a request is by using Shared Key.

Scenario: The mobile applications must be able to call the share pricing service of the existing retirement fund management system. Until the system is upgraded, the service will only support basic authentication over HTTPS.

The investment planning applications suite will include one multi-tier web application and two iOS mobile application. One mobile application will be used by employees; the other will be used by customers.
