質問 # 66
An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.
The architect decides to use vSAN ReadyNodes with the following configuration:
- Two disk groups with
- Write Intensive NVMe 800 GB drive for cache
- Four 3.84 TB Mixed Use NVMe for capacity Four 10 GbE ports.
Which element represents a risk that should be included in this design?

A. The existing network is 10 GbE capable
B. The use of NVMe drives for cache and capacity
C. The use of vSAN ReadyNodes

質問 # 67
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
- Management traffic
- vMotion traffic
- iSCSI traffic
- Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?

A. Use Network I/O Control to define a reservation for vMotion traffic.
B. Combine vMotion and Management traffic to make use of four adapters.
C. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
D. Configure a dedicated TCP/IP stack for vMotion traffic.

正解：C

解説：
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
