A VI workload domain is configured with an NSX overlay. After a change, workloads on different segments cannot reach each other, but both can reach the default gateway. Which issue is the MOST likely cause?

A customer plans to deploy mission-critical workloads that require deterministic throughput and low latency. They also want to reduce operational complexity for storage across clusters. Which workload domain storage design is MOST appropriate?

An enterprise requires that management-plane services remain available even if one rack fails. The current design places all management domain hosts, NSX Edge nodes, and management appliances in the same rack. Which change best aligns with this requirement?

A VCF administrator needs to rotate certificates used by core management components while ensuring trust is maintained across services and automation does not break. Which approach is MOST appropriate?

An architect is designing VMware Cloud Foundation (VCF) for a regulated environment. Security policy requires that the management plane be isolated from tenant workload traffic and that access to management UIs be tightly controlled. Which design best aligns with VCF best practices?

A customer wants to standardize virtual machine networking across multiple workload domains and needs consistent micro-segmentation policy enforcement. Which VCF component provides this capability?

A team wants to reduce the risk of configuration drift when expanding a VI workload domain with additional hosts. Which approach is recommended in VMware Cloud Foundation?
