    AZ-400 dumps exhibit

      Answer:

      Explanation:
      Box 1: Reader
      Members of the Reader role can view the organization agent pool as well as agents. You typically use this to add operators that are responsible for monitoring the agents and their health.
      Box 2: Service account
      Members of the Service account role can use the organization agent pool to create a project agent pool in a project. If you follow the guidelines above for creating new project agent pools,
      you typically do not have to add any members here. Incorrect Answers:
      In addition to all the permissions given the Reader and the Service Account role, members of the administrator role can register or unregister agents from the organization agent pool. They can also refer to the organization agent pool when creating a project agent pool in a project. Finally, they can also manage membership for all roles of the organization agent pool. The user that created the organization agent pool is automatically added to the Administrator role for that pool.

      AZ-400 dumps exhibit

        Answer:

        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.

        NEW QUESTION 7
        Your company . concerned that when developers introduce open source Libraries, it creates licensing compliance issues.
        You need to add an automated process to the build pipeline to detect when common open source libraries are added to the code base.
        What should you use?

        • A. Code Style
        • B. Microsoft Visual SourceSafe
        • C. Black Duck
        • D. Jenkins

        Answer: C

        Explanation: Secure and Manage Open Source Software
        Black Duck helps organizations identify and mitigate open source security, license compliance and code-quality risks across application and container portfolios. Black Duck Hub and its plugin for Team Foundation Server (TFS) allows you to automatically find and fix open source security vulnerabilities during the build process, so you can proactively manage risk. The integration allows you to receive alerts and fail builds when any Black Duck Hub policy violations are met.
        Note: WhiteSource would also be a good answer, but it is not an option here. References:

          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.

            Explanation: Case Study: 1 Overview
            Existing Environment
            Litware, Inc. e an independent software vendor (ISV) Litware has a main office and five branch offices.
            Application Architecture
            The company¡¦ s primary application is a single monolithic retirement fund management system based on ASP.NE T web forms that use logic written in V8.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 have 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 of 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.
            Requirements 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 easting 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 package.
            Litware has started an internal cloud transformation process and plans to use cloud based services whenever suitable.
            Litware wants to become proactive m detecting failures, rather than always waning for customer bug reports.
            Technical Requirements
            The company's investment planning applications suite must meet the following technical requirements:
            ¡E New incoming connections through the firewall must be minimized.
            ¡E Members of a group named Developers must be able to install packages.
            ¡E The principle of least privilege must be used for all permission assignments
            ¡E A branching strategy that supports developing new functionality in isolation must be used.
            ¡E Members of a group named Team leaders must be able to create new packages and edit the permissions of package feeds
            ¡E Visual Studio App Center must be used to centralize the reporting of mobile application crashes and device types in use.
            ¡E By default, all App Center must be used to centralize the reporting of mobile application crashes and device types in use.
            ¡E Code quality and release quality are critical. During release, deployments must not proceed between stages if any active bugs are logged against the release.
            ¡E 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 HUPS.
            ¡E The required operating system configuration tor the test servers changes weekly. Azure Automation State Configuration must be used to ensure that the operating system on each test servers configured the same way when the servers are created and checked periodically.
            Current Technical
            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.
