Deploy a GKE microservices livestream app that must scale automatically, remain highly available, and be resilient to hardware failures. How should you configure the deployment? (Choose two.)

To ensure high availability and resilience against hardware failures, a multi-zonal node pool distributes your workload across multiple zones. This prevents a single zone outage from taking down your entire application. Using cluster autoscaler automatically adjusts the number of nodes based on resource demands, while Horizontal Pod Autoscaler scales the number of pod replicas based on metrics like CPU utilization, ensuring the application can handle varying loads efficiently. Multiple zonal node pools would require manual distribution and management across zones, which is less efficient than a single multi-zonal configuration. Managed instance groups are for Compute Engine VMs, not directly for GKE node pools, which have their own autoscaling mechanisms. Manually scaling based on alerts is reactive and inefficient, failing to meet the requirement for automatic scaling.
