An organization is planning to expand their existing VMware Cloud Foundation (VCF) environment to meet an increased demand for new user-facing applications. The physical host hardware proposed for the expansion is a different model compared to the existing hosts, although it has been confirmed that both sets of hardware are compatible. The expansion needs to provide capacity for management tooling workloads dedicated to the applications, and it has been decided to deploy a new cluster within the management domain to host the workloads.
What should the architect include within the logical design for this design decision?
- The design justification stating that the separate cluster provides flexibility for manageability and connectivity of the workloads
- The design assumption stating that the separate cluster will provide complete isolation for lifecycle management
- The design implication stating that the management tooling and the VCF management workloads have different purposes
- The design qualities affected by the decision listed as Availability and Performance
Answer(s): A
Explanation:
In VCF, the logical design documents how design decisions align with requirements, often through justifications, assumptions, or implications. Here, adding a new cluster within the management domain for dedicated management tooling workloads requires a rationale in the logical design. Option A, a justification that the separate cluster enhances "flexibility for manageability and connectivity," aligns with VCF's principles of workload segregation and operational efficiency. It explains why the decision was made--improving management tooling's flexibility--without assuming unstated outcomes (like B's "complete isolation," which isn't supported by the scenario) or merely stating effects (C and D). The management domain in VCF 5.2 can host additional clusters for such purposes, and this justification ties directly to the requirement for dedicated capacity.
