Google Cloud Professional Cloud Developer — Question 168

Your company just experienced a Google Kubernetes Engine (GKE) API outage due to a zone failure. You want to deploy a highly available GKE architecture that minimizes service interruption to users in the event of a future zone failure. What should you do?

Answer options

Correct answer: B

Explanation

The correct answer is B, as deploying Regional clusters distributes your resources across multiple zones within a region, thereby providing high availability and reducing the risk of service interruption during a zone failure. Option A, Zonal clusters, are limited to a single zone and do not provide redundancy. Option C, Multi-Zone clusters, offer some level of availability but are still subject to limitations compared to Regional clusters. Option D, GKE on-premises clusters, does not address the issue of zone failures in the context of GKE services.
