70.An architect is tasked with expanding an existing VMware software-defined data center ( ) solution so that it can be used to deliver a virtual desktop infrastructure ( ) service off-shore development activities.
The production environment is currently delivered across two geographically dispersed data centers. The two data centers are currently connected to each other through multiple diversely routed, high bandwidth and low latency links. The current operations management components are deployed to a dedicated management cluster that is configured with N+1 redundancy. The current VMware software-defined data center ( ) has a monthly availability target of 99.5%, which includes all management components.
The customer requires that the new solution scale to support the concurrent running of 500 persistent virtual desktops. The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed using the same VMware operations management components. Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business critical services and must have an availability target of 99.9%.

31.An architect is tasked with recommending a solution for a company that is running out of VLANs. Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license. In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.
What should the architect recommend as a potential solution to provide support for additional VLANs?

22.An architect is tasked with reviewing the design of a VMware software-defined data center ( ) 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 contention
--The benchmarking cluster host configuration is:
--8 ESXi hosts with 2 sockets × 8 cores
--256 GB RAM divided evenly between sockets
--There is no resource contention
--The 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?
