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.)

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

Answer(s): A,B



Following a company merger, there are two data centers running vSphere environments. Both data centers are leveraging separate Layer 3 vMotion networks.

Which requirement must be met in order to enable vMotion migration between these locations?

  1. The vMotion service must be configured on the Management VMkernel adapter
  2. A dedicated TCP/IP stack for vMotion with a dedicated gateway must be configured
  3. A stretched vMotion network must be configured between data centers
  4. Virtual machines must be powered off in order to migrate them between data centers

Answer(s): B



An architect is designing a solution based on the following information:
-Each ESXi host has a single physical NIC with two 10 Gbps ports.
-There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times.
-There is no budget to purchase additional hardware.
-The hardware replacement SLA is based on a delivery agreement of two business days.

Which recommendation for the configuration of vSphere High Availability (HA) should the architect include in the design?

  1. Configure vSphere HA
    Configure % based admission control
    Configure two isolation addresses
    Consider an OEM with NIC failure conditions in their Proactive HA plugin
  2. Configure vSphere HA
    Set das.IgnoreRedundantNetWarning to true
    Consider an OEM with NIC failure conditions in their Proactive HA plugin
  3. Configure vSphere HA
    Configure two existing data stores for heartbeat
    Consider an OEM with NIC failure conditions in their Proactive HA plugin
  4. Configure Proactive HA
    Automation Level: Automated
    Remediation: Maintenance mode for all failures
    Consider an OEM with NIC failure conditions in their Proactive HA plugin

Answer(s): A



An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster. The development cluster host configuration is:

-4 ESXi hosts with 2 sockets × 16 cores
-512 GB RAM divided evenly between sockets
-There is no resource contention

The benchmarking cluster host configuration is:
-8 ESXi hosts with 2 sockets × 8 cores
-256 GB RAM divided evenly between sockets
-There is no resource contention

The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster.
Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.

What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

  1. The database tier breaches a single NUMA node boundary for the benchmarking cluster
  2. The database tier breaches a single NUMA node boundary for the development cluster
  3. The development cluster can support a lower %Ready time per vCPU
  4. The development cluster has more available RAM per host

Answer(s): C
