Câu 11: 3V0-2121: Advanced Design VMware vSphere 7.x

An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications. The platform has recently commissioned new hosts to update the development cluster. The development cluster host configuration is: ✑ 4 ESXi hosts with 2 sockets ֳ— 16 cores ✑ 512 GB RAM divided evenly between sockets ✑ There is no resource contentionThe benchmarking cluster host configuration is: ✑ 8 ESXi hosts with 2 sockets ֳ— 8 cores ✑ 256 GB RAM divided evenly between sockets ✑ There is no resource contentionThe customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data. What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

1. A. The database tier breaches a single NUMA node boundary for the benchmarking cluster — đáp án hiện tại
2. B. The database tier breaches a single NUMA node boundary for the development cluster
3. C. The development cluster can support a lower %Ready time per vCPU
4. D. The development cluster has more available RAM per host
