An architect will be updating an existing vSphere data center design.
The following information has been provided:
The new design must carry over existing VLANs for workloads.
The networking for storage must not share the data path with workload traffic.
The new design must be able to add additional VLANS.
The new design must reduce management overhead.
The new replacement servers have two 100 GB network cards.
Which design will meet the requirements for existing workload networks and allow scaling of additional networks?
- A . One vSphere standard switch (VSS) configuration Workload and storage traffic on separate uplinks
- B . One vSphere standard switch (VSS) configuration Workload and storage traffic on separate uplinks
- C . Two vSphere distributed switches (VDS)
Each VDS uses one uplink as active and the other uplink as passive
Existing and new workload traffic on one VDS and storage traffic on the other VDS - D . One vSphere distributed switch (VDS) configuration
The VDS uses aggregated uplinks
Workload and storage traffic on the aggregated uplinks
D
Explanation:
The customer’s requirements include the following:
Carry over existing VLANs for workloads: This can be easily achieved with a vSphere distributed switch (VDS), as it supports the configuration of VLANs and ensures that they can be applied to multiple ESXi hosts across the data center.
Networking for storage must not share the data path with workload traffic: By using aggregated uplinks in the VDS configuration, the architect can easily separate workload traffic and storage traffic by using different uplinks or VLANs. Aggregated uplinks ensure that there is sufficient bandwidth for both workloads and storage, while keeping them logically separated in terms of traffic management.
Add additional VLANs: A VDS supports the dynamic addition of VLANs. New VLANs can be added and managed centrally, reducing the complexity and management overhead when scaling the network.
Reduce management overhead: The use of a single VDS significantly reduces management
complexity compared to managing multiple vSphere standard switches (VSS). With VDS, network configuration and management are centralized and simplified across all ESXi hosts.
Given that the new replacement servers have two 100 GB network cards, the aggregated uplinks in a VDS configuration will provide the required network capacity while ensuring that traffic is properly segmented and scalable.
An architect is tasked with designing a repeatable edge hosting solution using VMware technologies that can be deployed to existing hotels across the world and operate independently of other locations.
During interviews with stakeholders, the architect notes the following information:
There are 123 hotels in total.
All hotels have a minimum of two 1 Gbps connections for guest Internet access.
The company operates hotels in four countries: Canada, USA, Cuba and Mexico.
The company is rebranding the hotels located in Mexico.
Which of these is a business factor that will impact this design?
- A . The company is rebranding the hotels located in Mexico.
- B . The company operates hotels in four countries: Canada, USA, Cuba and Mexico.
- C . There are 123 hotels in total
- D . All hotels have a minimum of two 1 Gbps connections for guest Internet access.
A
Explanation:
This is a business factor that will impact the design because rebranding the hotels in Mexico could lead to changes in the company’s requirements, such as the need for new branding, updated infrastructure, or integration of new services. These factors will influence the design decisions related to the edge hosting solution, potentially requiring special configurations or considerations for these locations.
An architect is responsible for extending the hosting design for a customer. The customer has a mission-critical 3-node application which is load balanced in an active/active/passive configuration. The application administrator requests that the virtual infrastructure team be responsible for maintaining platform level availability. An organizational policy exists to mandate the highest possible availability for mission-critical applications.
Based on the resource requirements, the architect has made the following design decision:
The target vSphere cluster contains three VMware ESXi host servers
A combination of which additional four physical design decisions should the architect make to maximize availability of the application? (Choose four.)
- A . The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.
- B . The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.
- C . The solution will create a VM-VM Affinity rule to keep virtual machines separate.
- D . The solution will create a host DRS group containing all hosts within the cluster.
- E . The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.
- F . The solution will create a virtual machine DRS group that contains all of the critical application workloads.
- G . The solution will create a VM-VM Affinity rule to keep virtual machines together.
A, B, E, F
Explanation:
The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.
Creating a VM-Host Affinity rule ensures that specific workloads are restricted to certain hosts, which can be useful to avoid placing critical applications on hosts that may not meet their availability requirements.
The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.
Enabling vSphere HA ensures that virtual machines are automatically restarted on other hosts in the event of a host failure. Setting the restart priority to "Highest" for mission-critical VMs ensures that these VMs will have the highest priority for restart if any issues arise.
The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.
Enabling vSphere Fault Tolerance (FT) ensures that the application VMs are fully protected by creating a live shadow VM that runs in lockstep with the primary VM. In the event of a host failure, the shadow VM will take over instantly, providing continuous availability for the application.
The solution will create a virtual machine DRS group that contains all of the critical application workloads.
Creating a virtual machine DRS (Distributed Resource Scheduler) group for critical workloads ensures that these VMs are placed and migrated to the optimal hosts based on the cluster’s resource requirements, improving availability and performance.
An architect is responsible for designing the upgrade of a brownfield vSphere-based solution for a financial services customer. The customer has a requirement to host a mission critical, latency sensitive stock trading application.
During initial meetings with the customer, the following information is provided:
The solution is currently running vSphere 7.0 U3
All vSphere distributed switches (VDS) are at version 7.0.0
The customer has provisioned new hardware with dedicated AMD Data Processing Units (DPU)
The mission critical applications must not be adversely affected by other workloads running in the environment
The architect has made the following design decisions:
The solution will upgrade the existing VMware vCenter Server to version 8.0
The solution will upgrade all existing VMware ESXi hosts to version 8.0
The solution will deploy VMware ESXi 8.0 for all new host servers
Which three additional design decisions should the architect make to ensure that the new hardware can be used to support the latency-sensitive application? (Choose three.)
- A . The solution will deploy new vSphere distributed switches (7.0.3) and connect the new DPU-enabled hosts.
- B . The solution will configure the hosts to use Network Time protocol (NTP).
- C . The solution will deploy all DPU-enabled VMware ESXi hosts into a dedicated VMware vSphere cluster.
- D . The solution will configure network offloads compatibility to support DPUs.
- E . The solution will deploy new vSphere distributed switches (8.0.0) and connect the new DPU-enabled hosts.
- F . The solution will upgrade all existing vSphere distributed switches to version 8.0.0.
C, D, E
Explanation:
Deploy all DPU-enabled VMware ESXi hosts into a dedicated VMware vSphere cluster:
Since the customer has a mission-critical, latency-sensitive stock trading application, it is essential to dedicate resources to these workloads to avoid contention with other less critical workloads. By placing DPU-enabled ESXi hosts in a dedicated cluster, the architect ensures that the hardware acceleration provided by the DPUs can be fully utilized by the latency-sensitive application without interference from other workloads.
Configure network offloads compatibility to support DPUs:
DPUs can offload network-related tasks from the CPU, such as network packet processing, and ensure better performance and lower latency. By configuring network offload compatibility in VMware ESXi, the system will leverage the DPU’s capabilities to offload network traffic processing, reducing the CPU burden and improving network performance for latency-sensitive applications.
Deploy new vSphere distributed switches (8.0.0) and connect the new DPU-enabled hosts:
For optimal support and performance with DPU-enabled hosts, the architect should deploy vSphere distributed switches (VDS) version 8.0.0. The newer version will be optimized for the hardware and provide better integration with DPUs, ensuring the latest features, improvements, and support for DPUs, thus maximizing the performance and minimizing latency for mission-critical applications.

Monitoring, logging and analytic tooling to provide visibility and troubleshooting of the whole solution
Support deployment via infrastructure-as-code methods for the additional management components
The customer also requests that the solution be as cost-effective as possible while still delivering a fast time to value for the organization.
Which design approach should the architect recommend to meet these requirements?
- A . Use VMware Validated Designs for the vSphere solution and VMware Validated Solutions for the additional components
- B . Use VMware Cloud Foundation for the vSphere solution and VMware Validated Solutions for the additional components
- C . Use VMware Cloud Foundation for the vSphere solution and a custom design for the additional components
- D . Use a custom design for the vSphere solution and VMware Validated Solutions for the additional components
B
Explanation:
The customer has outlined the following requirements:
Automated deployment and lifecycle management of the vSphere platform: This requires a solution that provides automated provisioning, management, and updates. VMware Cloud Foundation (VCF) is an integrated platform that provides automation for the lifecycle of the vSphere platform, including updates and patch management.
Self-Service deployment of virtual machines and other objects from a central catalog: VMware Cloud Foundation includes tools like vRealize Automation (part of VCF) that enable self-service provisioning of virtual machines and other resources. Additionally, VCF provides centralized management for provisioning and orchestration.
Monitoring, logging, and analytic tooling for visibility and troubleshooting: VMware Cloud Foundation integrates with vRealize Operations and vRealize Log Insight, which provides visibility, monitoring, and logging capabilities for the entire solution. These tools help in analytics and troubleshooting across the entire infrastructure.
Support deployment via infrastructure-as-code methods for additional management components: VMware Validated Solutions (such as vRealize Automation or vRealize Orchestrator) provide infrastructure-as-code capabilities, ensuring that the solution can be deployed in a consistent, repeatable manner, automating deployments of not just vSphere but also additional management components.
Cost-effectiveness with a fast time to value: VMware Cloud Foundation offers an integrated solution that is pre-configured and validated, which speeds up deployment and reduces operational complexity. By using VMware Validated Solutions for additional management components, the customer can leverage existing, tested solutions that are optimized for use with VCF, ensuring cost-effectiveness while meeting requirements.

What is a use case for a VMware Cloud Foundation consolidated architecture model?
- A . Run customer workloads in separate virtual infrastructure workload domains for scalability and autonomous licensing.
- B . Deploy an SDDC for a small-scale environment that can be extended later.
- C . Implement a dedicated management domain for high availability of management workloads.
- D . Deploy a large-scale environment with multiple vCenter instances for workload isolation.
B
Explanation:
The VMware Cloud Foundation consolidated architecture model is designed to support small-scale environments with the ability to scale as needed. In this model, management and workload domains are deployed on the same hardware, which is suitable for environments that start small but may need to expand later. It provides a simplified, cost-effective setup for organizations that want to implement a software-defined data center (SDDC) with flexibility to grow in the future.
An architect is designing the datastore configuration of a new vSphere-based solution.
The following information was obtained during the initial meeting with the customer:
There is currently 500 production and DMZ virtual machine workloads spread evenly across the primary and secondary site.
The profile of the workloads (per site) is as follows:
– DMZ:
— 75 x Small: 1 vCPU, 2GB RAM, 200 GB disk
– Production:
— 50 x Small: 1 vCPU, 2 GB RAM, 200 GB disk
— 100 x Medium: 2 vCPU, 4 GB RAM, 200 GB disk
— 25 x Large: 4 vCPU, 8 GB RAM, 500 GB disk
The average IO Profile per workload is 70/30 read/write.
The solution should cater to 10% storage growth in the first year.
The solution should cater to 15% virtual machine snapshot overhead.
The storage team has confirmed:
– A scalable external storage array has been deployed per site to support the storage requirements.
– The storage array will connect to all hosts using a dedicated Fibre Channel storage area network fabric.
– Usable storage capacity is available in 10 TB LUNs.
– As many LUNs as required can be provided.
– Every effort should be made to ensure the number of required LUNs is minimized.
The security team has stated that all DMZ and production workloads must remain logically isolated from each other.
Given the information provided, which three design decisions should the architect make to meet the requirements? (Choose three.)
- A . Six 10TB VMFS datastores will be configured on each site for all production workloads.
- B . Four 10TB VMFS datastores will be configured on each site for all production workloads.
- C . Each 10TB LUN will be configured as a VMFS datastore.
- D . Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.
- E . Each 10TB LUN will be configured as an NFS datastore.
- F . Seven 10TB VMFS datastores will be configured on each site for all workloads.
A, C, D
Explanation:
Six 10TB VMFS datastores will be configured on each site for all production workloads.
This choice is based on the need to distribute production workloads across multiple datastores while ensuring that each datastore is large enough to accommodate the space required by the workloads. Given the average sizes of the virtual machines and the growth and snapshot overhead, six 10TB VMFS datastores would be appropriate for production workloads, ensuring scalability while minimizing the number of LUNs.
Each 10TB LUN will be configured as a VMFS datastore.
VMFS (Virtual Machine File System) is the standard choice for vSphere environments when using Fibre Channel LUNs. It provides the necessary features, such as concurrency and high-performance access, for production workloads. This option is appropriate given that the storage array uses Fibre Channel for connection and VMFS is the standard file system for such configurations.
Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.
The DMZ workloads are smaller in number and storage requirements compared to the production workloads, so configuring two 10TB VMFS datastores for DMZ workloads will provide enough capacity while maintaining logical isolation. This approach also minimizes the number of LUNs required to meet the storage growth needs.
