deployed to the secondary site.
Which four additional design decisions should the architect make to ensure all requirements can be met? (Choose four.)

- E . The solution will use vSphere Lifecycle Manager baselines to perform patching and upgrading of
vSphere ESXi hosts in the secondary site. - F . The solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the primary site.
- G . The solution will ensure each vSphere cluster is configured with Distributed Power Management (DPM).
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
Which is a benefit of using vSAN stretched clusters in VMware Cloud Foundation?
- A . To enable high availability of virtual machines across different availability zones
- B . To reduce the cost by eliminating the need for additional hardware and software components

An architect is working on a security design for a shared storage environment. The storage array provides connectivity by the NFS protocol.
Which two design decisions could the architect include for this solution? (Choose two.)
- A . Create a dedicated storage network
- B . Create a dedicated VLAN
- C . Create a challenge handshake authentication protocol (CHAP) password to prevent unauthorized access
- D . Create dedicated volumes for sensitive data
- E . Create a dedicated Fibre Channel network
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.
An architect is creating a design for a new vSphere solution to meet the following business requirement:
REQ001 – Reduce operational expenditure
Which design decision could the architect include in the logical design to satisfy this requirement?
- A . Use vSphere Standard licenses on all clusters.
- B . Use heterogeneous hardware for the hosts in all clusters.
- C . Use vSphere Lifecycle Manager on all clusters.
- D . Use an N + 1 design to define the required capacity on all clusters.
An architect is tasked with updating the design of an existing vSphere-based solution for a pharmaceuticals customer. The update will include upgrade to VMware vCenter 8 and VMware vSphere 8 and the creation of a new cluster that will be used for ongoing research projects. The research project that is driving the need for an update includes a number of applications that are latency-sensitive.
The customer has confirmed the following information during the initial workshop:
The customer recently completed a right sizing exercise using VMware Aria Operations that resulted in a number of ESXi hosts becoming available for use.
Each of the VMware ESXi host servers is configured with:
— 2 x 20-core Intel Xeon CPU sockets
— 1024 GB RAM divided evenly between sockets There is no additional budget for purchasing hardware.
After confirming the existing hardware is still listed on the VMware Hardware Compatibility List (HCL), the architect makes the following design decisions with regard to the workload design:
The solution will support a maximum of 20 combined cores and sockets per virtual machine.
The solution will support a maximum of 512 GB RAM per virtual machine.
What should the architect document as justification for these design decisions?
- A . The maximum supported configuration will ensure efficient use of RAM by sharing memory pages between virtual machines.
- B . The maximum supported configuration will ensure the virtual machines will adhere to a single Non-Uniform Memory Access (NUMA) node boundary.
- C . The maximum supported configuration will ensure each virtual machine will exclusively consume a whole CPU socket.
- D . The maximum supported configuration will allow the creation of virtual machines that cross NUMA node boundaries resulting in improved overall performance.
