A company runs Backstage in production. They have set up monitoring and logging. After a recent upgrade, they notice that the backend logs are missing some entries that were present before the upgrade. What is the most likely cause?

The log level configuration was changed during the upgrade, filtering out lower-level logs.

The log aggregation system has a new retention policy that deletes logs after a shorter period.

The monitoring stack is no longer scraping the backend.

The backend is running fewer replicas, so less log output is generated.

Which practice is essential for securing a production Backstage deployment?

Using HTTP to simplify configuration

Enabling HTTPS for all external traffic

Disabling the backend health check endpoint

Storing secrets in the frontend bundle

What is the purpose of running database migrations in a Backstage deployment?

To update the database schema to match the application version

A company is deploying Backstage to production. They have built the frontend bundle and want to serve it from a CDN. The backend is deployed separately. What must they configure to ensure the frontend can communicate with the backend?

Set the `backend.baseUrl` in the frontend build configuration to the public HTTPS URL of the backend.

Set the `app.baseUrl` to the CDN URL and the `backend.baseUrl` to the CDN URL as well.

Place the frontend bundle in the backend's static directory.

Configure the CDN to proxy API requests to the backend.

A company is planning to deploy Backstage to production. They have a small team and want to minimize operational overhead. They expect moderate, steady usage. Which deployment approach is most appropriate?

Deploy the backend as a container on a managed container service and serve the frontend from a CDN.

Deploy the backend to a Kubernetes cluster with multiple replicas and use an ingress controller.

Run the backend on a single VM and serve the frontend from the same VM.

Use a serverless function for the backend and a CDN for the frontend.
