NEW QUESTION 29
You have a project in Azure DevOps that uses packages from multiple public feeds. Some of the feeds are unreliable.
You need to consolidate the packages into a single feed.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation

Step 1: Create a NuGet package.
NuGet and Maven are public package managers that support multiple feeds.
Step 2: Create an Azure Artifacts feed that uses upstream sources
If you want to use packages from multiple feeds, use upstream sources to bring packages from multiple feeds together into a single feed.
Step 3: Create a Micrtosoft Visual Studio project that includes all the packages Consume NuGet packages from upstream sources: Now you can open Visual Studio and install packages from the upstream sources you just configured.

Application Architecture
The company's primary application is a single monolithic retirement fund management system based on ASP.NET web forms that use logic written in VB.NET. Some new sections of the application are written in C#.
Variations of the application are created for individual customers. Currently, there are more than 80 live code branches in the application's code base.
The application was developed by using Microsoft Visual Studio. Source code is stored in Team Foundation Server (TFS) in the main office. The branch offices access the source code by using TFS proxy servers.
Architectural Issues
Litware focuses on writing new code for customers. No resources are provided to refactor or remove existing code. Changes to the code base take a long time, as dependencies are not obvious to individual developers.
Merge operations of the code often take months and involve many developers. Code merging frequently introduces bugs that are difficult to locate and resolve.
Customers report that ownership costs of the retirement fund management system increase continually.
The need to merge unrelated code makes even minor code changes expensive.
Customers report that bug reporting is overly complex.
Planned changes
Litware plans to develop a new suite of applications for investment planning. The investment planning applications will require only minor integration with the existing retirement fund management system.
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.
Litware plans to move to a more agile development methodology. Shared code will be extracted into a series of packages.
Litware has started an internal cloud transformation process and plans to use cloud-based services whenever suitable.
Litware wants to become proactive in detecting failures, rather than always waiting for customer bug reports.
Technical requirements
The company's investment planning applications suite must meet the following requirements:
New incoming connections through the firewall must be minimized.

Members of a group named Developers must be able to install packages.

The principle of least privilege must be used for all permission assignments.

A branching strategy that supports developing new functionality in isolation must be used.

Members of a group named Team Leaders must be able to create new packages and edit the

permissions of package feeds.
Visual Studio App Center must be used to centralize the reporting of mobile application crashes and

device types in use.
By default, all releases must remain available for 30 days, except for production releases, which must

be kept for 60 days.
Code quality and release quality are critical. During release, deployments must not proceed between

stages if any active bugs are logged against the release.
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 required operating system configuration for the test servers changes weekly. Azure Automation

State Configuration must be used to ensure that the operating system on each test server is configured the same way when the servers are created and checked periodically.
Current Technical Issue
The test servers are configured correctly when first deployed, but they experience configuration drift over time. Azure Automation State Configuration fails to correct the configurations.
Azure Automation State Configuration nodes are registered by using the following command.

Explanation:
SonarCloud is a cloud service offered by SonarSource and based on SonarQube. SonarQube is a widely
adopted open source platform to inspect continuously the quality of source code and detect bugs,
vulnerabilities and code smells in more than 20 different languages.
Note: The SonarCloud Azure DevOps extension brings everything you need to have your projects analyzed on SonarCloud very quickly.
Incorrect Answers:

NEW QUESTION 37
You have an Azure subscription that contains resources in several resource groups.
You need to design a monitoring strategy that will provide a consolidated view. The solution must support the following requirements:
* Support role-based access control (RBAC) by using Azure Active Directory (Azure AD) identities.
* Include visuals from Azure Monitor that are generated by using the Kusto query language.

* Use the latest data available for each visual.
What should you use to create the consolidated view?

A. Azure Monitor
B. Azure Data Explorer
C. Microsoft Power Bl
D. Azure dashboards

Answer: B

Explanation:
There are several tools available for running queries in Azure Data Explorer, including Kusto.
Kusto uses a role-based access control (RBAC) model, under which authenticated principals are mapped to roles, and get access according to the roles they're assigned.
Note: Azure Data Explorer is a highly scalable and secure analytics service that enables you to do rich exploration of structured and unstructured data for instant insights. Optimized for ad-hoc queries, Azure Data Explorer enables rich data exploration over raw, structured, and semi-structured data delivering fast time to insight.

NEW QUESTION 38
You need to recommend a solution for deploying charts by using Helm and Title to Azure Kubemets Service (AKS) in an RBAC-enabled cluster.
Which three commands should you recommend be run m sequence? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:
Step 1: Kubectl create
You can add a service account to Tiller using the --service-account <NAME> flag while you're configuring Helm (step 2 below). As a prerequisite, you'll have to create a role binding which specifies a role and a service account name that have been set up in advance.
Example: Service account with cluster-admin role
$ kubectl create -f rbac-config.yaml
serviceaccount "tiller" created
clusterrolebinding "tiller" created
$ helm init --service-account tiller
Step 2: helm init
To deploy a basic Tiller into an AKS cluster, use the helm init command.
Step 3: helm install
To install charts with Helm, use the helm install command and specify the name of the chart to install.

You need to recommend an integration strategy for the build process of a Java application. The solution must meet the following requirements:
* The builds must access an on-premises dependency management system.
* The build outputs must be stored as Server artifacts in Azure DevOps.
* The source code must be stored in a Git repository in Azure DevOps.
Solution: Configure an Octopus Tentacle on an on-premises machine. Use the Package Application task in the build pipeline.
Does this meet the goal?

A. No
B. Yes

Answer: B

Explanation:
Octopus Deploy is an automated deployment server that makes it easy to automate deployment of ASP.NET web applications, Java applications, NodeJS application and custom scripts to multiple environments.
Octopus can be installed on various platforms including Windows, Mac and Linux. It can also be integrated with most version control tools including VSTS and GIT.
When you deploy software to Windows servers, you need to install Tentacle, a lightweight agent service, on your Windows servers so they can communicate with the Octopus server.
When defining your deployment process, the most common step type will be a package step. This step deploys your packaged application onto one or more deployment targets.
When deploying a package you will need to select the machine role that the package will be deployed to.
