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?

1. A. The number of 10 GbE capable ports in the vSAN ReadyNode
2. B. The use of vSAN ReadyNodes
3. C. The existing network is 10 GbE capable
4. D. The use of NVMe drives for cache and capacity

Correct Answer: C

A Cloud Service Provider wants to introduce backup as a service for a customer’s vSphere-based virtual machines.
The following information is noted:

Which two recommendations should the architect make to help the customer incorporate the service? (Choose two.)

1. A. Enable and tag traffic on the backup distributed port group
2. B. Add a new two-port 10 GbE NIC per ESXi host
3. C. Replace the existing NIC with a two-port 25 GbE NIC per ESXi host
4. D. Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network
5. E. Create a new virtual switch using the 1 GbE uplinks

Correct Answer: AB

During a requirements gathering workshop, the customer provides the following information:

1. A. Use Route Based on Physical NIC Load.
2. B. Use Network I/O Control with Shares.
3. C. Use Network I/O Control with Reservation.
