   A solution summary for a VxRail cluster contains the following line items: 'Node Model: VxRail V670F', 'Memory per Node: 512 GB', 'vSAN Capacity Tier: 7.68 TB NVMe', and 'Design Assumption: 25% capacity overhead reserved for vSAN operations'. During a design review, the customer's storage administrator asks where the 25% overhead figure is documented so it can be audited. Which section of the solution summary should the consultant reference?

   • AThe node configuration section, which details the physical hardware specifications of each node model.
   • BThe resource allocation section, which shows how CPU and memory are assigned to specific workloads.
   • CThe executive summary section, which provides a high-level overview of the business case for the project.
   • DThe design assumptions section, which records the operational overhead and other sizing premises used in the design.

   In the VxRail design process, when is the solution summary typically used?

   • AOnly during the initial discovery call with the customer
   • BDuring the design phase to capture and share the proposed architecture
   • CAfter implementation to document the as-built environment
   • DAt the start of the project to define the project scope

   A solution summary for a VxRail cluster specifies 'vSAN FTT: 1' and 'Erasure Coding: Enabled' for a 4-node cluster. The customer's application team has a requirement for a maximum write latency of 2 ms under normal operations. The consultant is validating the design and finds that the solution summary does not include a performance validation section. What is the most appropriate action?

   • ARemove erasure coding from the design to eliminate the write overhead and meet the latency requirement.
   • BChange the design to FTT=2 to improve write performance and meet the latency requirement.
   • CFlag the missing performance validation as a gap in the solution summary and recommend a proof-of-concept or performance modeling to validate the latency requirement.
   • DAssume the design meets the latency requirement because FTT=1 and erasure coding are standard configurations.
