What is a key consideration for configuring a highly available Cloud Pak for Business Automation...

The correct answer is C. Highly available Cloud Pak for Business Automation deployments require platform, workload, and storage resilience. IBM's high-availability guidance includes setting up storage with high-availability features, such as Red Hat OpenShift Data Foundation, along with distributing pods across worker nodes and deploying control planes and worker nodes across availability zones. Storage is critical because many CP4BA services are stateful: content repositories, databases, message/event infrastructure, indexes, and runtime state must remain consistent and recoverable after pod, node, or zone failure. Option A refers to WebSphere node-agent behavior, which applies to traditional application-server clustering rather than Kubernetes-native CP4BA operations. Option B concentrates infrastructure in one fault domain and therefore weakens availability. Option D is also traditional-topology oriented; containerized deployments use OpenShift or Kubernetes routing and service mechanisms for load balancing. A correct CP4BA HA design combines redundant pods, multi-zone topology, persistent volumes, storage replication, database HA, and Kubernetes health management.
