  • Question 4:

    As part of designing a greenfield vSphere-based hosting solution, an architect is responsible for defining a patch management solution for the virtual infrastructure.

    During initial meetings with the customer, the following information is provided:

    There are two geographically dispersed physical sites (primary and secondary) in scope for the solution.

    The inter-site connectivity has been classified as low bandwidth and high latency.

    The customer has the following requirements:

    REQ001 - Only IT Security Team-approved versions of VMware Tools should be installed across all workloads within the infrastructure.

    REQ002 - The solution should minimize traffic across the inter-site link.

    REQ003 - Upgrades to the virtual infrastructure should continue in the event of a failure with either site.

    A combination of which three design decisions could the architect make to ensure the requirements are met? (Choose three.)

    A. The solution will set the UserVars.ToolsRamdisk advanced system setting on each VMware ESXi host to "1" (enabled).
    B. The solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.
    C. The solution will use VMware Autodeploy to ensure the latest version of VMware Tools is deployed to each workload.
    D. The solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared Repository
    E. The solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.
    F. The solution will create a shared repository on a VMFS datastore within the primary site that contains all approved versions of VMwareTools.

  • Question 5:

    During the creation of a vSphere-based design solution, an architect identifies the following assumption:

    The customer will be responsible for providing all licensing for the vSphere platform.

    The storage hardware has sufficient capacity for future workload scale.

    The data center offers sufficient power, cooling and rack space for workload scale.

    When documenting each assumption within the design, which two corresponding pieces of information must the architect also define? (Choose two.)

    A. The data center does not have sufficient capacity to meet the requirements for workload scale.
    B. The storage hardware may not have capacity for future workload scale.
    C. Additional data center locations have been identified. Contracts will be signed to bring the capacity online within 12 months.
    D. The project sponsor is responsible for the data center capacity. The administrator is accountable and the architect is informed.
    E. Additional storage capacity can be procured to expand the solution in the future as needed.

  • Question 6:

    An architect is designing a vSphere-based private cloud solution to support the following customer requirements:

    The solution should support running 5,000 concurrent production compute workloads across the primary and secondary sites.

    The solution should support running 1,000 development compute workloads within the secondary site.

    The solution should support up to 50 management workloads across the primary and secondary site.

    The solution must ensure the isolation of virtual infrastructure management operations between management and compute workloads.

    The solution must ensure that the hosting of any virtual infrastructure management workloads does not impact the amount of capacity available for compute workloads.

    The solution must ensure that all production compute workloads are physically isolated from development compute workloads.

    The solution must ensure that the operational management of compute workloads in the secondary site is possible in the event of a disaster affecting the primary site.

    How many VMware vCenter instances will the architect need to include in the design to meet these requirements?

    A. 5
    B. 3
    C. 2
    D. 4

  • Question 7:

    An architect is reviewing the information provided by a customer for a new vSphere solution design. The customer requests that the solution use multiple network connections for the ESXi management network to increase resilience.

    A. Availability
    B. Manageability
    C. Performance
    D. Recoverability

  • Question 8:

    An architect is responsible for extending the hosting design for a customer. The customer has a mission-critical 3-node application which is load balanced in an active/active/passive configuration. The application administrator requests that

    the virtual infrastructure team be responsible for maintaining platform level availability. An organizational policy exists to mandate the highest possible availability for mission-critical applications.

    Based on the resource requirements, the architect has made the following design decision:

    The target vSphere cluster contains three VMware ESXi host servers

    A combination of which additional four physical design decisions should the architect make to maximize availability of the application? (Choose four.)

    A. The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.
    B. The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.
    C. The solution will create a VM-VM Affinity rule to keep virtual machines separate.
    D. The solution will create a host DRS group containing all hosts within the cluster.
    E. The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.

    G. The solution will create a VM-VM Affinity rule to keep virtual machines together.

  • Question 9:

    An architect is discussing the design of a vSphere solution with a customer. The following requirements have been defined for the solution:

    The solution must provide data encryption at rest

    The solution must provide the ability to reduce the amount of storage consumed from duplicate data

    The solution must minimize the amount of resources consumed by the encryption process.

    The architect has made a design decision that VM Encryption will be used to meet these requirements.

    Which two implications should the architect include in the design in relation to this design decision? (Choose two.)

    A. Encryption is a CPU-intensive feature. Resource Pools should be used to assign shares to the encrypted VMs.
    B. When data is encrypted by the storage device, the effectiveness of de-duplication on the storage will be unaffected.
    C. Encryption is a CPU-intensive feature. The ESXi hosts should use the AES-NI BIOS setting to improve the performance of encryption and reduce CPU utilization.
    D. Encryption is a memory-intensive feature. The ESXi hosts should use the AES-NI BIOS setting to improve the performance of encryption and reduce memory utilization.
    E. When data is encrypted by the ESXi host, the effectiveness of de-duplication on the storage may be reduced.

  • Question 10:

    An architect is tasked with designing the implementation of the VMware Validated Solutions in an existing VMware Cloud Foundation environment that includes:
