During a requirements gathering workshop, the customer provides the following information: Each host has 2 × 10 GbE NIC EtherChannel is not currently configured No changes can be made to the physical network Network throughput must be prioritized for defined critical services Which two recommendations should the architect make with regard to virtual networking? (Choose two.)
An architect decides to separate virtual desktops and application servers into separate vSphere clusters to meet security and management requirements. What are two implications of this design decision? (Choose two.)
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.)
An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC). During the discovery phase, the following information is documented: Cluster One Six ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is enabled and set to automated Fully Automated vSphere DRS Transparent Page Sharing (TPS) is enabled Cluster Two Eight ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is disabled Partially Automated vSphere DRS Transparent Page Sharing (TPS) is disabled Cluster Three Three ESXi hosts vSphere HA with admission control is disabled Proactive HA is not supported Transparent Page Sharing (TPS) is disabled Virtual Machine Resource Profile 1 Memory sharing techniques should not be used Virtual machines should be automatically restarted in the event of host failure if resources are available Automated initial virtual machine placement Virtual Machine Resource Profile 2 Memory sharing techniques should not be used Virtual machines should be automatically restarted in the event of host failure regardless of available resources Automated initial virtual machine placement Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)
A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service (SaaS) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Proalhazi@1tocol (PTP) and a local stratum-1 network time server. Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux. Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? (Choose three.)
Which requirement would be classified as a functional requirement within the application design documentation?

(Choose two.)
During a requirements gathering workshop, the customer provides the following requirement (REQ) and constraints (CON): REQ01: The customer is looking for a way to limit database virtual machine (VM) placement to save on CPU licensing costs. CON01: There is a single cluster with no budget to scale. CON02: All virtual machines must run on the consolidated cluster. Which two design decisions should the architect make to meet the customer requirement? (Choose two.)

Question 78 - 3V0-21.21 discussion

Report
Export

A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.

Per the defined logical network configuration, there are two network adapters each used for:

Management traffic vMotion traffic iSCSI traffic Virtual machine traffic Which design decision should the architect make to meet the customer requirement?

A.
Use Network I/O Control to define a reservation for vMotion traffic.
Answers
A.
Use Network I/O Control to define a reservation for vMotion traffic.
B.
Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
Answers
B.
Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
C.
Configure a dedicated TCP/IP stack for vMotion traffic.
Answers
C.
Configure a dedicated TCP/IP stack for vMotion traffic.
D.
Combine vMotion and Management traffic to make use of four adapters.
Answers
D.
Combine vMotion and Management traffic to make use of four adapters.
Suggested answer: B

Explanation:

https://kb.vmware.com/s/article/2007467

https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-acrossmultiple-uplinks-on-distributed/td-p/491336

https://www.virtuallyboring.com/multi-nic-vmotion/

We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernelinterfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it forvMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
