• ✗

  gcloud functions call my-function --data '{"key":"value"}'

  Why it's wrong here

  Running `gcloud functions call` sends a test invocation payload to an already-deployed Cloud Function; it performs no deployment actions. The `--data` flag supplies the event data for that invocation, not deployment configuration. To deploy a function, you need `gcloud functions deploy` with a runtime, trigger, and source.

• ✗

  gcloud run deploy my-function --source . --platform managed

  Why it's wrong here

  This command deploys a container image to Cloud Run, which is Google's managed platform for containerized applications, not Cloud Functions. Cloud Functions are source-based and require a runtime (like python39) and a trigger flag; Cloud Run uses Docker containers and the `--platform managed` flag to select the fully managed service. Even if the function logic is identical, the deployment target and command syntax differ.

• ✓

  gcloud functions deploy my-function --runtime python39 --trigger-http

  Why this is correct

  This command correctly deploys an HTTP-triggered Cloud Function: `gcloud functions deploy` creates or updates a function resource, `--runtime python39` selects the Python 3.9 execution environment, and `--trigger-http` configures an HTTPS endpoint that invokes the function on web requests. No other trigger type is needed. The command will return a URL for the deployed function.

• ✗

  gcloud functions deploy my-function --runtime python39 --trigger-topic my-topic

  Why it's wrong here

  This command deploys a Cloud Function, but it uses `--trigger-topic my-topic` to subscribe the function to messages published on a Pub/Sub topic. It will not create an HTTP endpoint; instead, messages on the topic trigger the function asynchronously. Since the question asks for an HTTP trigger, this option is incorrect.
