                                              NEW QUESTION # 384
                                              Your company is building a new web application.
                                              You plan to collect feedback from pilot users on the features being delivered.
                                              All the pilot users have a corporate computer that has Google Chrome and the Microsoft Test & Feedback extension installed. The pilot users will test the application by using Chrome.
                                              You need to identify which access levels are required to ensure that developers can request and gather feedback from the pilot users. The solution must use the principle of least privilege.
                                              Which access levels in Azure DevOps should you identify? To answer, select the appropriate options in the answer area.
                                              NOTE: Each correct selection is worth one point.

                                              NEW QUESTION # 385
                                              You are implementing a package management solution for a Node.js application by using Azure Artifacts.
                                              You need to configure the development environment to connect to the package repository. The solution must minimize the likelihood that credentials will be leaked.
                                              Which file should you use to configure each connection? To answer, drag the appropriate files to the correct connections. Each file may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content NOTE: Each correct selection is worth one point.

                                              Answer:

                                              Explanation:

                                              Explanation:
                                              All Azure Artifacts feeds require authentication, so you'll need to store credentials for the feed before you can install or publish packages. npm uses .npmrc configuration files to store feed URLs and credentials. Azure DevOps Services recommends using two .npmrc files.
                                              Feed registry information: The .npmrc file in the project
                                              One .npmrc should live at the root of your git repo adjacent to your project's package.json. It should contain a "registry" line for your feed and it should not contain credentials since it will be checked into git.
                                              Credentials: The .npmrc file in the user's home folder
                                              On your development machine, you will also have a .npmrc in $home for Linux or Mac systems or $env.HOME for win systems. This .npmrc should contain credentials for all of the registries that you need to connect to. The NPM client will look at your project's .npmrc, discover the registry, and fetch matching credentials from $home/.npmrc or $env.HOME/.npmrc.

                                              NEW QUESTION # 386
                                              You have an Azure DevOps release pipeline named Pipeline1. You plan to use Pipelinel to deploy infrastructure as code (laC) resources to Azure. You need to create templates to define which resources to deploy. Which template formats should you use?

                                              Answer: C


                                              NEW QUESTION # 387
                                              You have a project in Azure DevOps named Project1 that references an Azure Artifacts feed named Feed1.
                                              You have a package named Package1 that has the versions shown in the following table.

                                              You need to perform a build of Project1. Which version of Package1 will be used?
