3V0-24.25: VMware Certified Advanced Professional - vSphere Kubernetes Service

The Istio release download endpoint supplies the release archive containing istioctl and the installation resources. The documented Linux/macOS bootstrap form is curl -L https://istio.io/downloadIstio | sh -; therefore the matching command is the curl -L https://istio.io/downloadIstio choice. istioctl is run directly after it is obtained, not as kubectl istioctl.
