There is a dedicated ESXi cluster for all line-of-business applications.

  • Network traffic is serviced by NSX-T.

There is a dedicated ESXi cluster for virtual desktop infrastructure (VDI).

  • Network traffic is serviced by NSX-T.

The application owner is requesting approval to install a new service that must be protected as per the Payment Card Industry (PCI) Data Security Standard.

Which additional non-functional requirement should the architect include in the design to support the new service?

Options:

A.  

The vSphere hosting platform and all PCI application virtual machines must be assessed against Payment Card Industry (PCI) Data Security Standard compliance.

B.  

The vSphere hosting platform and all PCI application virtual machines must be assessed for SOX compliance.

C.  

The vSphere hosting platform and all PCI application virtual machine network traffic must be routed via NSX-T.

D.  

The vSphere hosting platform and all PCI application virtual machines must be monitored using the vRealize Operations Compliance Pack for Payment Card Industry.

Options:

A.  

%Ready

B.  

Disk Write latency

C.  

CPU

D.  

Ballooned memory

E.  

IOPS

The virtual infrastructure environment must connect application virtual machines and management services to new physical network switches

B.  

The virtual infrastructure environment must connect application virtual machines and management services to separate distributed virtual switches (DVS)
