A VMware Cloud Foundation (VCF) architect is planning for the expansion of an existing VCF instance.
The existing VCF instance is deployed with a single workload domain. The number of ESXi hosts has
grown to the maximum number the existing vCenter can support.
Which design decision would the architect need to make to allow the existing VCF Instance to add more
ESXi hosts?
Answer
- A. Deploy a second vCenter server appliance within the existing workload domain
- B. Deploy a second workload domain within the existing VCF Instance Correct
- C. Deploy a second cluster within the existing vCenter
- D. Deploy a second VCF Instance within the existing VCF Fleet
Explanation
A single workload domain in VCF maps to a single vCenter instance. When the host limit for that vCenteris reached (typically ~1000 hosts per vCenter), the correct and supported scale-out design is to deploy a
second VI workload domain, which comes with its own dedicated vCenter instance, allowing continued
expansion without affecting the existing domain.
