You will deploy containerized workloads to AKS clusters distributed across four Azure regions. Which storage solution ensures that updated container images are automatically replicated to all regions hosting the AKS clusters?

Premium SKU Azure Container Registry (ACR) supports geo-replication, which automatically synchronizes container images across multiple Azure regions. This ensures that AKS clusters in different regions can pull images from a local registry replica, reducing latency and providing high availability. Geo-redundant storage (GRS) accounts replicate data but are not designed for container image distribution to AKS. Azure Content Delivery Network (CDN) is for caching web content, not container images for AKS. Azure Cache for Redis is an in-memory data store for caching application data, not container images.
