What is a benefit of using a scale-out method for handling vSphere cluster growth?

An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an online retail customer who has a primary and secondary data center as well as 10 distribution hubs.

The customer has provided the following business requirements to help inform the design:

• The solution must support the running of up to 1,000 concurrent virtual machines across the primary and secondary data center.
• The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.
• The solution must support the separation of management and lines-of-business application virtual machines.
• All management components (including directory services, backup, automation, operations and logging) must be deployed to the primary data center.
• All virtual infrastructure components must have redundancy of N+1.
• All sites are connected to each other using a wide area network that has multiple diversely routed links.
• The solution should support a monthly uptime target of 99.9%.
• The recovery time objective (RTO) for the solution must be four hours.
• The recovery point objective (RPO) for the solution must be 24 hours.

Given the information from the customer, which assumption should the architect include in the design?

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 Proalhazi@1tocol (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.)
