In Backstage, what is the primary responsibility of a frontend plugin?

To execute business logic and access external data sources

To manage database schemas and migrations

To render user interface components and handle user interactions

To authenticate users and manage authorization tokens

A Backstage plugin fetches data from an external CI system and displays the build status on a component page. How should this plugin be classified?

Both frontend and backend plugins

Neither frontend nor backend plugin

A plugin only adds a new tab to the catalog entity page that displays information already available from the Backstage catalog API. What type of plugin is this?

Both frontend and backend plugin

A Backstage frontend plugin needs to display a list of cloud resources from AWS. The AWS credentials are stored in the backend. Which approach should be used to get the data to the frontend?

The backend plugin writes the data to a file that the frontend reads

The frontend plugin uses the AWS SDK directly with the stored credentials

The frontend plugin asks the user to provide AWS credentials

The backend plugin fetches the data from AWS and exposes it via an API endpoint

An organization wants to create a plugin that enforces a policy: when a user requests to create a new component, the plugin must check the component's name against a list of restricted words stored in a database. If the name is restricted, the creation request must be rejected. Where should this logic be implemented?

In the backend plugin, because it enforces business rules and accesses the database

In the frontend plugin, using a client-side database

In the frontend plugin, because it handles user input

In both frontend and backend, with the frontend doing the final check
