What do Service-Level Agreement (SLA) requirements define?

During the installation of ESXi, what is the minimum number of network interfaces required for management and vMotion traffic, respectively?

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.)

Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?

An architect is tasked with designing the vSphere cluster layout for a customer. The customer is NOT sure how many clusters are required or the number of hosts to use in any of the clusters.
The customer has provided the following requirements:
- The placement of Linux and Windows machines (end user virtual machines) needs to be controlled for license compliance.
- Access to virtual machines such as Active Directory and DHCP (infrastructure virtual machines) should be restricted to just the platform administration team.
- Infrastructure virtual machines should not prevent end user virtual machines from consuming their allocated resources.
- Utilization for the current infrastructure's virtual machines is less than end user virtual machines.
- The platform needs to provide the ability to lifecycle manage the hosts without impacting end user virtual machines.
- The platform needs to account for the predicted future growth of end user virtual machines being very high, while for infrastructure virtual machines being very low.
- There are a total of 15 physical servers for use across the platform.
Which of the proposed cluster layouts would meet the customer's requirements?
