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?

An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.

Which ESXi deployment method should the architect use?

Stateless cached vSphere Auto Deploy

Stateless vSphere Auto Deploy

Manual install of each ESXi host with an image from USB

Stateful vSphere Auto Deploy

Question 5

An architect is designing a new VMware solution for a customer that has a number of different resource profiles.

The following are the business requirements for the design:

The solution must support virtual machines with the following storage profiles:

- Write-intensive

- Backup

- Write-Once-Read-Many (WORM) archive

The solution must support migration of virtual machine disks between storage profiles.

The WORM archive data must be located at an isolated secure site.

The backup storage array must only be connected to a backup media server.

All data should be recoverable from backup.

Which design decision should the architect make to meet the business requirements?

The solution will leverage a single storage array for the WORM archive and write-intensive storage profiles

The solution will leverage the same array for the backup and write-intensive storage profiles

The solution will leverage a different array for each storage profile

Question 6

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.

REQ02 The infrastructure must initially run 100 virtual machines.

REQ03 Ten of the virtual machines must be compliant with internal security standard.
