'The service ___ itself at startup.' Which verb is correct?
Services 'register themselves' with the service registry at startup, publishing their location (host/port) so other services can discover them.

What is a 'health check endpoint' in a service registry context?
A health check endpoint (e.g., /health or /ping) is polled by the registry to determine if the service instance is healthy and should receive traffic.

'The registry ___ unhealthy instances.' Which verb fits this sentence?
The registry 'deregisters' (removes) unhealthy instances so that clients don't route traffic to them. This happens automatically when health checks fail.
