   (npmjs.com, NuGet.org, Maven Central, and PyPI) Upstream sources enable you to use a single feed to store both the packages you produce and the packages you consume from "remote feeds": both public feeds (for example, npmjs.com, NuGet.org, Maven Central, and PyPI) and authenticated feeds (that is, other Azure DevOps Services feeds in your organization or in organizations in your Azure Active Directory (Azure AD) tenant).

5. Question 455 · 540 in bank

   Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You use Azure Pipelines to build and test a React.js application. You have a pipeline that has a single job. You discover that installing JavaScript packages from npm takes approximately five minutes each time you run the pipeline. You need to recommend a solution to reduce the pipeline execution time. Solution: You recommend using pipeline artifacts. Does this meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: B

   Explanation

   ==>Answer "B" / "No" [When to use artifacts versus caching] Pipeline caching and pipeline artifacts perform similar functions but are designed for different scenarios and shouldn't be used interchangeably. [Use pipeline artifacts] when you need to take specific files produced in one job and share them with other jobs (and these other jobs will likely fail without them). [Use pipeline caching] when you want to improve {build time} by reusing files from previous runs (and not having these files won't impact the job's ability to run).
