Management traffic
vMotion traffic
iSCSI traffic
Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?
- A. Configure a dedicated TCP/IP stack for vMotion traffic.
- B. Combine vMotion and Management traffic to make use of four adapters.

NEW QUESTION 50
An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can be used to deliver a virtual desktop infrastructure (VDI) 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 (SDDC) has a monthly availability target of 99.5%, which includes all 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%.
Given the information from the customer, which two assumptions would the architect include in the design? (Choose two.)
- A. The existing management cluster has enough available capacity to host any VDI service management component
- B. The existing operations monitoring tools have sufficient capacity to monitor the new VDI services
