C. Maximum tolerable downtime
D. The level of isolation required between virtual machine classifications
正解：D

質問 2：
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, supporting all management services.
All network traffic is via distributed virtual switches (DVS).
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 machine network traffic must be routed via NSX-T.
B. The vSphere hosting platform and all PCI application virtual machines must be monitored using the vRealize Operations Compliance Pack for Payment Card Industry.
C. The vSphere hosting platform and all PCI application virtual machines must be assessed for SOX compliance.
D. The vSphere hosting platform and all PCI application virtual machines must be assessed against Payment Card Industry (PCI) Data Security Standard compliance.

質問 3：
A Cloud Service Provider wants to introduce backup as a service for a customer's vSphere-based virtual machines.
The following information is noted:
They have a single four-port (2 × 10 GbE and 2 × 1 GbE) NIC per ESXi host All top-of-rack (ToR) switches are 10 GbE and fully populated The backup traffic must not impact existing services Which two recommendations should the architect make to help the customer incorporate the service? (Choose two.)
A. Add a new two-port 10 GbE NIC per ESXi host
B. Replace the existing NIC with a two-port 25 GbE NIC per ESXi host
C. Create a new virtual switch using the 1 GbE uplinks
D. Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network
E. Enable and tag traffic on the backup distributed port group

質問 4：
An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.
During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:
The solution must support the concurrent running of 1,000 virtual machines The production environment must be delivered across two geographically dispersed data centers All virtual machines must be capable of running in either data center.
The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.
The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes The service owner has stated that it is critical to ensure the availability target of 99.9% All virtual machine backups must be completed using the existing backup service The recovery time objective (RTO) for the service is five minutes The recovery point objective (RPO) of the service is four hours Which two elements represent risks to the successful delivery of this solution? (Choose two.)
A. The use of only two data centers
B. The RTT on the link between the two data centers
C. The use of vSAN ReadyNodes
D. The use of the existing backup service
E. The network connectivity between data center sites

質問 6：
An architect is designing a new vSphere platform for a customer to meet the following requirements:
The platform must be deployed into five physically separate sites.
The sites are spread across multiple regions.
Some sites require more than one vCenter Server.
The platform must provide an administrator with the ability to access virtual infrastructure components across all sites from a single management tool instance.
Which single sign-on (SSO) design recommendation will meet these requirements?
A. Use an SSO domain per region
B. Use an SSO domain per vCenter Server instance
C. Use an SSO domain per site
D. Use an SSO domain across all vCenter Server instances
