A Backstage project uses Yarn workspaces. A developer needs to add a new plugin that will only be used during development and testing, not in the production build. Which section of the package.json should the plugin be added to, and what command should be used to install it?

Add to 'devDependencies' and run 'yarn add --dev '

Add to 'dependencies' and run 'yarn add '

Add to 'optionalDependencies' and run 'yarn add --optional '

Add to 'peerDependencies' and run 'yarn add '

In a Backstage monorepo using Yarn workspaces, where are dependencies typically hoisted?

To the system's global node_modules

To each package's own node_modules

To the root node_modules directory

After a failed yarn install, which step is recommended to ensure a clean state before retrying?

Delete the node_modules directory and re-run 'yarn install'.

Run 'yarn add' for each dependency manually.

Ignore the error and run 'yarn start'.

Run 'yarn upgrade' to fix the installation.
