GCP Associate Cloud Engineer Practice Question

The gcloud compute instances list command returns all VM instances in the selected project. Using a filter string lets you narrow the results; the expression status=RUNNING restricts the list to running VMs, while zone:(europe-west1-b) limits the search to that specific zone. Adding --format=json produces machine-readable JSON output. Alternative commands shown either use invalid flags, use describe instead of list, omit the JSON format, or apply the filter incorrectly, so they would fail to meet one or more of the stated requirements.
