1. Question 1 · 1

   An architect is reviewing the information provided by a customer for a new vSphere solution design. The customer has stated that some of the virtual machines (VMs) that will be hosted on the new solution handle credit card information from their users as part of an online payment application, and that some of the information will need to be stored temporarily to allow transactions to be completed.
