NEW QUESTION # 45
A customer requests a review of its current vSphere platform design.
The following information is noted:
There are three different workload profiles for the virtual machines:
- Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
- Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.

NEW QUESTION # 56
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 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.
