An architect is reviewing the information provided by a customer for a new vSphere solution design. The customer has stated that some of the virtual machines (VMs) that will be hosted on the new solution handle credit card information from their users as part of an online payment application, and that some of the information will need to be stored temporarily to allow transactions to be completed. Therefore, the solution must be designed to be able to mask or hash the stored information as they will need to show compliance against common industry standards that contain references to the requirements for handling sensitive information.
Which design quality is being requested by the customer?
- A . Manageability
- B . Performance
- C . Security
- D . Recoverability
C
Explanation:
The customer is requesting that the solution meet security requirements, specifically around handling sensitive information (such as credit card data). The need to mask or hash stored information for compliance with industry standards (e.g., PCI-DSS) is a security-focused design requirement. This ensures that sensitive data is protected and compliant with regulations, making security the primary design quality being requested.
An architect is designing a vSphere-based private cloud solution to support the following customer requirements:
The solution should support running 5,000 concurrent production compute workloads across the primary and secondary sites.
The solution should support running 1,000 development compute workloads within the secondary site.
The solution should support up to 50 management workloads across the primary and secondary site.
The solution must ensure the isolation of virtual infrastructure management operations between management and compute workloads.
The solution must ensure that the hosting of any virtual infrastructure management workloads does not impact the amount of capacity available for compute workloads.
The solution must ensure that all production compute workloads are physically isolated from development compute workloads.
The solution must ensure that the operational management of compute workloads in the secondary site is possible in the event of a disaster affecting the primary site.
How many VMware vCenter instances will the architect need to include in the design to meet these requirements?
- A . 5
- B . 3
- C . 2
- D . 4
B
Explanation:
To meet the requirements outlined, the architect will need to design a solution with three VMware vCenter instances.
Here’s why:
Isolation of Virtual Infrastructure Management Operations: The management workloads (such as vCenter itself, along with other virtual infrastructure management tools) should be isolated from compute workloads. This suggests the need for a separate vCenter instance to manage the infrastructure without impacting compute workloads.
Physical Isolation of Production and Development Workloads: Production workloads and development workloads need to be physically isolated, which suggests the need for different vCenter instances to maintain separation.
Support for Operational Management in the Event of a Disaster: In the event of a disaster affecting the primary site, the secondary site should still be able to manage compute workloads. This could be achieved by having a vCenter instance in each site (primary and secondary) to ensure continued management in the event of a failure.
Breakdown of the three vCenter instances:
vCenter 1: Manages production workloads across both primary and secondary sites.
vCenter 2: Manages development workloads in the secondary site, ensuring isolation from production.
vCenter 3: Manages the virtual infrastructure management workloads, ensuring isolation from compute workloads.
An architect is designing the virtual networking components of a vSphere-based solution that will provide an environment for the development of a new latency sensitive stock trading application.
The following information was identified within the initial meeting with the customer:
The customer has vCenter Standard and vSphere Standard licenses left over from a previous project.
The customer’s CFO has approved budget for additional purchases, if required.
The following requirements were also identified during the meeting:
The solution must support 500 development workloads concurrently running in the secondary site.
The solution must support the ability to complete all vSphere Operational Management centrally.
The solution must ensure business-critical applications are not impacted by vSphere system-level operations.
Given the requirements, the architect has decided on a single 20-node cluster for development.

- A . The solution will configure Traffic Shaping policies to restrict network bandwidth on ingress and egress.
- B . The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.
- C . The solution will deploy VMware vSphere Standard on all hosts within the cluster.
- D . The solution will deploy a single VMware Standard Switch that will be configured identically on each host.
- E . The solution will deploy a single vSphere Distributed Switch with each host connected to it.
- F . The solution will configure Network I/O control to ensure that system-level bandwidth does not impact workload network traffic.
B, E, F
Explanation:
The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.
VMware vSphere Enterprise Plus offers advanced networking and storage features that will support the required high availability, performance, and management capabilities. Features such as Distributed Switches and Network I/O Control (NIOC) are critical to meeting the business-critical application and performance requirements for the latency-sensitive stock trading application.
The solution will deploy a single vSphere Distributed Switch with each host connected to it.
A vSphere Distributed Switch (VDS) is ideal for managing network configurations centrally across multiple hosts, which meets the requirement for centralized vSphere operational management. It also ensures consistent network configurations and simplifies network management at scale.
The solution will configure Network I/O control to ensure that system-level bandwidth does not impact workload network traffic.
Network I/O Control (NIOC) is essential for prioritizing network traffic, ensuring that latency-sensitive workloads are not impacted by other system-level or less critical traffic. This is crucial for the performance requirements of the stock trading application.
A company is expanding and will be deploying new vSphere environments in multiple new locations.
All environments use datastores backed by multiple storage technologies and vendors.
How can the architect create a design to efficiently and repeatedly distribute existing company virtual machine (VM) templates to multiple new locations?
- A . Use storage array replication tools to replicate the storage volume holding the company VM templates to each remote site.
- B . Upload company templates to a cloud provider and download to each new location.
- C . Create a published content library and have the new locations subscribe to it.
- D . Create a local content library at each site and manually copy only needed templates.
C
Explanation:
This option allows for a centralized repository of VM templates that can be efficiently and repeatedly distributed to multiple locations. By creating a published content library, you enable the new locations to subscribe to this library, ensuring that the templates are synchronized and easily accessible. This approach minimizes manual effort and ensures consistency across all sites.
What is a benefit of using workload domains in VMware Cloud Foundation?
- A . Workload domains require separate instances of vCenter, decreasinq complexity and manaqement overhead.
- B . Workload domains allow for manual provisioninq of vSphere clusters usinq the SDDC Manaqer.
- C . Workload domains are pre-configured and automatically deployed according to industry best practices for SDDC implementation.
- D . Each workload domain can only support a maximum of three ESXi hosts, makinq it easy to manaqe small workloads.
C
Explanation:
Workload domains in VMware Cloud Foundation provide a way to logically organize and manage resources within the software-defined data center (SDDC). They are pre-configured and automatically deployed by SDDC Manager, which follows VMware’s industry best practices for architecture and configuration. This reduces manual effort and complexity, ensuring that the implementation is aligned with VMware’s recommended configurations.
Which four factors should an architect consider when calculating the number of hosts required for a new multi-site vSphere-based solution that utilizes external storage? (Choose four.)
- A . The workload profile (CPU and memory) of each workload
- B . The amount of resources required for virtual machine (VM) swap and VM snapshots
- C . The number of existinq workloads that will be decommissioned prior to the completion of project
- D . The number of existinq workloads that will be miqrated onto the new solution
- E . The number of network connections per physical host server
- F . The future physical location of any workloads
- G . The hardware specification of the underlying infrastructure
A, B, D, G
Explanation:
The workload profile (CPU and memory) of each workload
Understanding the CPU and memory requirements for each workload is crucial for determining the capacity needed on each host. This helps ensure that each host has sufficient resources to run the virtual machines (VMs) efficiently.
The amount of resources required for virtual machine (VM) swap and VM snapshots
VM swap files and snapshots require additional storage and compute resources. It’s important to account for these resource requirements to avoid overloading the hosts or running into resource bottlenecks.
The number of existing workloads that will be migrated onto the new solution
Knowing how many workloads will be migrated allows the architect to estimate the total resource demand and determine the number of hosts required to support the migrated workloads effectively.
The hardware specification of the underlying infrastructure
The hardware specifications of the hosts, including the CPU, memory, storage, and network interfaces, play a significant role in determining how many hosts are needed to support the workloads. More powerful hardware may reduce the number of hosts required, while less capable hardware might increase the number needed.
An architect is working on the design documentation for a new vSphere solution. The architect has completed a conceptual model based on the following requirement:
REQ001 C The solution must use shared storage
What could the architect include in the logical design to meet this requirement?
- A . The use of an NFS mount point, including the IP address of the NFS server it is hosted on
- B . The use of an all flash vSAN datastore
- C . The use of an HCI solution for a datastore
- D . The use of File Based Storage, including the list of permissions applied to the share
A
Explanation:
The requirement specifies that the solution must use shared storage, which refers to a storage solution that can be accessed by multiple ESXi hosts simultaneously. NFS (Network File System) is a widely used method for providing shared storage in a vSphere environment. By including the NFS mount point and the IP address of the NFS server, the architect can specify how the shared storage will be configured and accessed by the ESXi hosts, meeting the requirement for shared storage.
An architect is working on a new VMware vSphere design and notes the following information during interviews with stakeholders:
The company has previously worked with multiple VMware partners
The company has an internal security policy that is referenced in long running contracts
The company has an Enterprise License Agreement (ELA) with VMware
The company has a multi-year cloud subscription agreement
Which of these is a business factor that will impact this design?
- A . The company has previously worked with multiple VMware partners.
- B . The company has an Enterprise License Agreement (ELA) with VMware.
- C . The company has an internal security policy that is referenced in long running contracts.
- D . The company has a multi-year cloud subscription agreement.
B
Explanation:
The Enterprise License Agreement (ELA) is a business factor that will impact the design because it defines the licensing structure, which directly influences the solution’s cost, scalability, and use of VMware products. The ELA could provide benefits such as discounted licensing costs, a predefined set of VMware products, or specific terms and conditions that must be adhered to in the design.
An architect is tasked with designing the implementation of the VMware Validated Solutions in an existing VMware Cloud Foundation environment that includes:
Intelligent Operations Management
Intelligent Logging and Analytics
Which two design elements must the architect include in the design to be able to accomplish the deployment of these two solutions? (Choose two.)
- A . vSphere Lifecycle Manager
- B . Application Virtual Network (AVN)
- C . NSX Edge Cluster
- D . vSAN Stretched Cluster
- E . NSX Federation
A, C
Explanation:
vSphere Lifecycle Manager:
vSphere Lifecycle Manager (vLCM) is essential for ensuring that the VMware Cloud Foundation (VCF) environment is consistently managed and updated. Intelligent Operations Management and Intelligent Logging and Analytics require a well-integrated and managed infrastructure. vLCM automates the lifecycle management of vSphere clusters, ensuring that all components are compliant and correctly configured, which is critical for the deployment of VMware Validated Solutions.
NSX Edge Cluster:
An NSX Edge Cluster is necessary to provide networking services, including routing and firewalling, for the VMware Cloud Foundation environment. These solutions, especially those focusing on Intelligent Operations Management and Intelligent Logging and Analytics, typically rely on NSX for network segmentation, security, and operational insights. The NSX Edge Cluster is required for these networking functionalities to integrate properly into the architecture.
An architect is responsible for the lifecycle management design for a brownfield vSphere-based solution.
The following information has been provided during initial meetings around the new solution:
Existing heterogeneous server hardware will be used to provide the hosting platform.
The available hardware is:
— 10 servers that contain 2 x 20-Core Intel Xeon processors and 512 GB RAM from Vendor A
— 10 servers that contain 2 x 24-Core Intel Xeon processors and 768 GB RAM from Vendor A
— 20 servers that contain 2 x 16-Core AMD EPYC processors and 512 GB RAM from Vendor B
— 10 servers that contain 1 x 24-Core AMD EPYC processors and 256 GB RAM from Vendor C All of the hardware is currently listed on the VMware Hardware Compatibility List (HCL).
All existing server hardware has 36 months vendor support remaining. The requirements from the customer are:
REQ001 – The solution must support the hosting of 5,000 workloads across two physical sites. REQ002 – The solution should minimize the number of clusters.
REQ003 – The solution must ensure that there is no impact to service when completing upgrades.
Given the resource requirements needed for the solution, the architect has calculated that all of the existing servers will be required to provide sufficient resources for the new environment. The Intel-based servers will be deployed to the primary site and the AMD-based servers will be
deployed to the secondary site.
Which four additional design decisions should the architect make to ensure all requirements can be met? (Choose four.)
- A . The solution will create an Intel-based 20-node vSphere cluster in the primary site and an AMD-based 30-node vSphere cluster in the secondary site.
- B . The solution will use VMware SDDC Manager to perform lifecycle management of the solution.
- C . The solution will ensure each vSphere cluster supports a minimum of N + 1 redundancy.
- D . The solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the secondary site.
- 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).
B, C, D, F
Explanation:
The solution will use VMware SDDC Manager to perform lifecycle management of the solution.
VMware SDDC Manager provides centralized lifecycle management for a vSphere-based environment, especially in VMware Cloud Foundation. This is crucial for automating and streamlining updates, upgrades, and patches, ensuring that the solution remains operational during lifecycle events and that there is no service impact during these processes.
The solution will ensure each vSphere cluster supports a minimum of N + 1 redundancy.
Ensuring N + 1 redundancy within each cluster will provide high availability and fault tolerance. This means that each cluster will have enough capacity to continue operating even if one host fails, meeting the requirement to avoid service disruption during host failures or maintenance activities.
The solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the secondary site.
vSphere Lifecycle Manager (vLCM) images allow for consistent and automated management of ESXi host configurations and upgrades. By using images, the architect ensures that all hosts in the secondary site are aligned with the required configuration for upgrades, thus simplifying the process and minimizing downtime during upgrades.
The solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the primary site.
Just like for the secondary site, using vLCM images in the primary site ensures that the Intel-based servers are configured consistently and updated seamlessly. This approach minimizes service disruption and ensures smooth upgrades for all hosts in the primary site.
