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?

An architect is finalizing the design for a new vSphere platform based on the following information: All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes. All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes. All management virtual machines will be hosted on a dedicated cluster. A total of ten physical sites will be used to host virtual machines. In the event of one physical datacenter becoming unavailable, the manageability of the virtual infrastructure in the remaining data centers should not be impacted. Access to configure the management virtual machines via vCenter Server must be controlled through the management Active Directory domain. Access to configure the Windows and Linux virtual machines must be controlled through the resource Active Directory domain. The management and resource Active Directory domains are part of separate Active Directory forests and do not have any trusts between them. The design will use Active Directory with Integrated Windows Authentication. How should the architect document the vCenter Server configuration for this design?

Which two of the listed requirements would be classified as manageability non-functional requirements? (Choose two.)

Question 72

An architect is designing a new vSphere cluster. The requirement is to provide a total of 96 CPU cores and 1.5 TB RAM across all hosts.

The following information has been provided:

Two different physical hardware profiles are available for the ESXi hosts in the cluster.

- Profile 1: 16 CPU cores and 256 GB RAM

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?

All business application virtual machines can be deployed into a single cluster within the primary data center.

Each distribution hub should be configured with a backup device.

The wide area network has sufficient bandwidth to support centralized management.

Each cluster will have a minimum of four hosts.
