You plan to share packages that you wrote, tested, validated, and deployed by using Azure Artifacts.
You need to release multiple builds of each package by using a single feed. The solution must limit the release of packages that are in development.
What should you use?
A. local symbols
B. views
C. global symbols
D. upstream sources
Correct Answer: D
Explanation/Reference:
Upstream sources enable you to manage all of your product’s dependencies in a single feed. We recommend publishing all of the packages for a given product to that product’s feed, and managing that product’s dependencies from remote feeds in the same feed, via upstream sources. This setup has a few benefits:
Simplicity: your NuGet.config, .npmrc, or settings.xml contains exactly one feed (your feed).
Determinism: your feed resolves package requests in order, so rebuilding the same codebase at the same commit or changeset uses the same set of packages
Provenance: your feed knows the provenance of packages it saved via upstream sources, so you can verify that you’re using the original package, not a custom or malicious copy published to your feed
Peace of mind: packages used via upstream sources are guaranteed to be saved in the feed on first use; if the upstream source is disabled/removed, or the remote feed goes down or deletes a package you depend on, you can continue to develop and build

Should be view
Answer is B. Views
Views enable you to share subsets of the NuGet, npm, Maven, Python and Universal Packages package-versions in your feed with consumers. A common use for views is to share package versions that have been tested, validated, or deployed but hold back packages still under development and packages that didn’t meet a quality bar.
