A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service (SaaS) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Protocol (PTP) and a local stratum-1 network time server.
Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux.
Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? (Choose three.)

• A.Use Microsoft Windows Server as the guest operating system.
• B.Configure the chrony time-sync agent on each virtual machine guest operating system.
• C.Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.
• D.Add a precision clock virtual device to each virtual machine running the application.
• E.Use a Linux distribution as the guest operating system.
• F.Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
