Exam Professional Cloud Developer topic 1 question 156 discussion

Regional Clusters - Span multiple zones within a region. - May not guarantee that all zones within the region are always available. - Can provide some level of redundancy, but might not be as resilient as multi-zone clusters in the event of a zone failure. Multi-Zone Clusters - Distribute your workload across multiple zones within a region. - Ensure that your application remains highly available and resilient to zone failures. - Automatically move your workloads to the remaining healthy zones if one zone fails. - Provide the highest level of availability among the GKE deployment options. In summary, while both regional and multi-zone clusters can provide redundancy, multi-zone clusters offer a higher level of availability by distributing your workload across multiple zones, ensuring minimal service disruption in the event of a zone failure.

B is correct.

Regional cluster with master plane to be in multiple zones is a correct option.

B is the answer. https://cloud.google.com/kubernetes-engine/docs/concepts/types-of-clusters#regional_clusters A regional cluster has multiple replicas of the control plane, running in multiple zones within a given region. Nodes in a regional cluster can run in multiple zones or a single zone depending on the configured node locations. By default, GKE replicates each node pool across three zones of the control plane's region. When you create a cluster or when you add a new node pool, you can change the default configuration by specifying the zone(s) in which the cluster's nodes run. All zones must be within the same region as the control plane.
