Question 8

Single choice

An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.

Which ESXi deployment method should the architect use?

A
Stateless cached vSphere Auto Deploy
B
Stateless vSphere Auto Deploy
C
Manual install of each ESXi host with an image from USB
D
Stateful vSphere Auto Deploy

The following are the business requirements for the design: The solution must support virtual machines with the following storage profiles:
- Write-intensive
- Backup
- Write-Once-Read-Many (WORM) archive
The solution must support migration of virtual machine disks between storage profiles.
The WORM archive data must be located at an isolated secure site.
The backup storage array must only be connected to a backup media server.
All data should be recoverable from backup.

Question 10

Single choice

There is a request for approved virtual machine applications through a new vSphere platform's integrated automation portal. The platform was built following all provided company security guidelines and has been assessed against Sarbanes-Oxley Act of 2002 (SOX) regulations.

The platform has the following characteristics: vRealize Operations is being used to monitor all clusters.

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?

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.
