2V0-13.25 Exam Dumps : VMware Cloud Foundation 9.0 Architect

According to the VMware Cloud Foundation 9.0 Architecture Guide under the VMware Kubernetes Service (VKS) Lifecycle Management section, the management and orchestration of Kubernetes clusters within VCF occur through three controller layers. These are explicitly identified as the Virtual Machine Service, the Cluster API (CAPI), and the Cloud Provider Plugin (CPP).

The Virtual Machine Service (VMS) acts as the integration layer between vSphere and Kubernetes, enabling Kubernetes objects (such as clusters and machines) to be represented as vSphere resources. The Cluster API provides declarative lifecycle management for Kubernetes clusters, automating provisioning, upgrades, and scaling through Kubernetes-native APIs. The Cloud Provider Plugin integrates the cluster lifecycle with vSphere infrastructure management, ensuring alignment of networking, storage, and compute resource operations.

Together, these three controller layers deliver a fully automated, policy-driven, and API-centric approach to cluster provisioning, maintenance, and scaling in VCF-based environments, supporting consistent lifecycle operations across workload domains. This framework replaces traditional manual configuration and ensures full compliance with VCF’s software-defined architecture principles.

The VMware Cloud Foundation 9.0.2 Design Guide identifies Harbor as the enterprise-grade container registry integrated with vSphere with Tanzu and Supervisor Clusters. It states:

“Harbor provides a cloud-native registry that supports image scanning, replication, and image signing. It is the recommended solution for storing, securing, and distributing container images within VCF environments.”

Harbor integrates with vSphere Namespaces and supports content trust, vulnerability scanning, and image replication across multiple sites — capabilities not available with Docker Hub or Gitea, and only partially supported in Azure ACR.

Therefore, Harbor is the correct and VMware-recommended component for a Supervisor image store that requires enterprise security and replication capabilities.

Physical Switch MTU set to 9000 ensures optimal performance and reduced packet fragmentation for vSAN and NSX-T overlay networks—critical in HA scenarios.

vSAN Cache Tier Sizing at 800GB provides the necessary performance buffer to support high I/O operations and ensures continued service availability under failure or maintenance events.

Other options like DHCP lease time or NIC load-based routing do not directly influence availability SLA adherence.
