A large enterprise is evaluating Backstage as a developer portal. They want to understand how it can integrate with their existing internal tools and services, and how it can be extended to meet their specific needs. Which statement best describes Backstage's architecture in this context?

Backstage is a modular platform with a core app and backend, where plugins provide integrations and extensions.

Backstage is a monolithic application that must be used as-is without customization.

Backstage is a plugin that runs inside another developer portal.

Backstage is a cloud service that provides a fixed set of tools.

A company is customizing Backstage to match their internal workflows. They have a set of custom plugins and a heavily customized frontend. They are concerned about the effort required to upgrade Backstage to a new version. What is the best strategy to minimize upgrade friction?

Keep customizations in separate plugins and use configuration for theming, avoiding changes to core code.

Use a third-party fork of Backstage that includes the customizations.

Fork the Backstage repository and apply customizations directly.

Avoid using plugins and instead modify the core app to include custom features.

A company wants to standardize the creation of new microservices, ensuring that each new service follows the same repository structure, CI/CD pipeline, and catalog registration. They want developers to be able to initiate this process from the Backstage portal. What should they implement?

Write a script that developers run locally to create the service.

Manually create each service and add it to the catalog.

Create a Scaffolder template that defines the repository structure, CI/CD, and catalog info.

Use the Software Catalog's built-in 'create service' feature.

What is the primary role of the Software Catalog in Backstage?

To provide a real-time dashboard of application performance metrics.

To manage user permissions and access control for the Backstage portal.

To store and organize metadata about software components, such as services, libraries, and websites.

To store the source code of all software components.

A company is developing a Backstage plugin that will expose sensitive infrastructure data. They have strict security requirements: only authenticated users with a specific role can access the data, and the plugin must not leak data through other Backstage features like search. What should they implement?

Rely on the authentication provider to restrict access.

Hide the plugin from the sidebar for unauthorized users.

Use the Scaffolder to create the plugin with built-in security.

Define a permission policy for the plugin and ensure the plugin does not index sensitive data in search.
