   In the context of VxRail design, what is a reference workload?

   • AA workload that is defined by the VxRail administrator after the cluster is deployed
   • BA workload that is used only for benchmarking hardware components, not for sizing decisions
   • CA standardized workload profile that represents a typical or common application pattern, used as a baseline for sizing and configuration
   • DA workload that is generated by the customer's actual production applications to test the VxRail cluster

   A hospital is designing a VxRail cluster for a new electronic health record (EHR) system. The vendor's sizing tool shows a reference workload for 'OLTP database' with 50,000 IOPS, 2 ms latency, and 5 TB capacity. The hospital's actual EHR workload is expected to have 30,000 IOPS, 4 ms latency, and 12 TB capacity. The design team is about to order nodes based on the reference workload. What should the team do first?

   • AUse the reference workload as-is but add one extra node to compensate for the capacity difference.
   • BSelect a different reference workload that has a higher IOPS value, regardless of capacity.
   • COrder the nodes sized for the reference workload because it represents the vendor's validated configuration.
   • DAdjust the reference workload inputs to match the hospital's actual IOPS, latency, and capacity, then re-run the sizing tool.

   What is the primary role of a reference workload in VxRail design?

   • ATo provide a starting point for estimating the number and type of nodes needed for a cluster
   • BTo guarantee that the cluster will meet all performance requirements without further testing
   • CTo define the exact software versions that must be installed on the VxRail nodes
   • DTo replace the need for any customer input during the design process

   How do different reference workloads map to VxRail node types?

   • AWorkloads with high IOPS map to nodes with more CPU cores, not storage
   • BNode type is chosen based on the number of VMs, not workload characteristics
   • CAll reference workloads map to the same node type regardless of characteristics
   • DWorkloads with high storage capacity needs map to nodes with larger disk configurations

   A VxRail architect is designing a cluster for a customer that will run a mix of VDI and a small database workload. The reference workload for VDI specifies 15,000 IOPS and 5 TB capacity for 500 desktops. The database reference workload specifies 10,000 IOPS and 2 TB capacity. The customer expects 500 desktops and a database that requires 8,000 IOPS and 1 TB. The architect is considering using a single cluster for both workloads. What is the most appropriate approach to determine the total node requirements?

   • ASum the IOPS and capacity of both reference workloads (25,000 IOPS, 7 TB) and size the cluster for the combined total.
   • BUse the database reference workload only, because it is more critical to the business.
   • CUse the VDI reference workload only, because it has higher IOPS and capacity requirements.
   • DSize the cluster for the VDI workload and add one extra node for the database.
