AI / Dependabot Interview questions
How does Dependabot handle private package registries/dependencies?
By default, Dependabot can only see and update dependencies from public registries (npmjs.org, PyPI,
Maven Central, and so on). For dependencies hosted on a private, authenticated registry (a company's internal
package feed, a private npm scope), Dependabot needs explicit registries configuration providing
the registry's URL and credentials so it can actually reach and query that private source.

Without this configuration, Dependabot simply can't see or propose updates for privately-hosted dependencies at all — it's not that it handles them poorly, it's that it has no visibility into them whatsoever until explicitly told where to look and given the credentials to authenticate.
Can Dependabot see private, authenticated registries by default?
What happens to privately-hosted dependencies without this registries configuration?
