Cloud Functions interview questions

1. A.server code that runs automatically in response to an event like a document write or a new user signing up
2. B.the added latency when a new instance must boot from scratch because no warm one is available to serve a request
3. C.a typed endpoint invoked from the client SDK that automatically forwards the user's auth context and handles serialization
4. D.a deployed handler invoked directly over a URL, used to build callable APIs and webhooks

Answer + AI explanation with Pro

1. A.HTTP function
2. B.Callable function
3. C.Cold start
4. D.Background trigger

Answer + AI explanation with Pro

1. A.Background trigger — a typed endpoint invoked from the client SDK that automatically forwards the user's auth context and handles serialization
2. B.Background trigger — the added latency when a new instance must boot from scratch because no warm one is available to serve a request
3. C.Background trigger — server code that runs automatically in response to an event like a document write or a new user signing up
4. D.Background trigger — the design rule that event handlers tolerate being delivered more than once, because the platform guarantees at-least-once execution
