Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  gcloud container clusters create my-cluster --zone us-central1-a --num-nodes 3

  Why it's wrong here

  Using --zone creates a zonal cluster, not a regional one. The control plane and all nodes reside in a single zone, so the cluster lacks multi-zone redundancy. To meet the requirement of a regional cluster, you must use --region instead.

• ✓

  gcloud container clusters create my-cluster --region us-central1 --num-nodes 3

  Why this is correct

  This is the standard way to create a regional GKE cluster. The --region flag designates a regional cluster where the control plane is replicated across three zones in that region, and nodes are spread across those zones (3 nodes per zone by default with --num-nodes 3). This provides higher availability and is exactly what the engineer needs.

• ✗

  gcloud container clusters create my-cluster --region us-central1 --nodes 3

  Why it's wrong here

  The correct flag is --num-nodes, not --nodes. GKE's CLI does not recognize --nodes; it will fail with an error because the flag is unknown. Even if the flag were interpreted as node count, the number of nodes is per zone in a regional cluster, so using --nodes would be ambiguous. The proper syntax is --num-nodes.

• ✗

  gcloud compute clusters create my-cluster --region us-central1 --size 3

  Why it's wrong here

  The command should be gcloud container clusters, not gcloud compute clusters. gcloud compute is for Compute Engine resources like VM instances, not GKE clusters. Additionally, the flags are incorrect: GKE uses --num-nodes, not --size, and requires --region or --zone. This would fail because gcloud compute clusters is not a valid command.
