    B. The average resource utilization of a virtual machine
    C. The size (CPU/RAM/storage) of the average virtual machine
    D. The guest operating system for each virtual machine
    E. The size (CPU/RAM/storage) of the vSphere hosts

  • Question 4:

    An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can be used to deliver a virtual desktop infrastructure (VDI) service off-shore development activities.

    The production environment is currently delivered across two geographically dispersed data centers. The two data centers are currently connected to each other through multiple diversely routed, high bandwidth and low latency links. The current operations management components are deployed to a dedicated management cluster that is configured with N+1 redundancy. The current VMware software-defined data center (SDDC) has a monthly availability target of 99.5%, which includes all management components.

    The customer requires that the new solution scale to support the concurrent running of 500 persistent virtual desktops. The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed using the same VMware operations management components. Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business critical services and must have an availability target of 99.9%.

    Given the information from the customer, which two assumptions would the architect include in the design? (Choose two.)

    A. The existing virtual infrastructure has sufficient capacity to host the new VDI workloads
    B. The existing operations monitoring tools have sufficient capacity to monitor the new VDI services
    C. The existing management cluster has enough available capacity to host any VDI service management component
    D. The management cluster has N+1 redundancy
    E. The VDI service has a higher service-level agreement (SLA) than the operations management SLA

  • Question 5:

    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.

  • Question 6:

    The Chief Information Security Officer (CISO) for an organization is concerned about the security posture of the operating system images that are used for the provisioning of their Software-as-a-Service (SaaS) applications. The organization

    is in a growth period. The organization is opening a new data center to launch its next phase of new SaaS-based solutions.

    The DevOps team currently creates encrypted virtual machine (VM) templates that are used for various operating systems and adds these to the vSphere inventory. The DevOps team already uses a published content library and has been

    granted a role with the ability to add and delete library items.

    The following requirements have been noted:

    Impacts to the DevOps team's operational processes must be kept to a minimum.

    The DevOps team must be able to regularly check out a copy of the image for updates and check in a new version of the image.

    Images must be synchronized from the primary data center to the new data center.

    Which three recommendations should the architect make to design a content library solution that will meet these requirements? (Choose three.)

    A. Clone virtual machines as VM templates to the published content library
