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. Answer: 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. 2. Total Hosts: - 4 hosts for production in the primary site. - 4 hosts for production in the secondary site. - 1 host for development in the secondary site. - 1 additional host for N + 1 resiliency in both sites. Total hosts required = 4 (primary production) + 4 (secondary production) + 1 (secondary development) + 2 (N + 1) = 12 hosts. 3.An architect is reviewing the information gathered from an initial requirements gathering workshop. The following requirements have been identified: REQ001 C The architecture must support tracking of administrative logons and actions. REQ002 C The architecture must support class three (three nines or 99.9%) system availability. REQ003 C The architecture must report on system usage in terms of CPU, memory, storage and network. REQ004 C The architecture must provide for system recovery point objective (RPO) of two hours. REQ005 C The architecture must provide access to a precision time protocol (PTP) for time synchronization. Which two of the listed requirements would be classified as business (formerly functional) requirements? (Choose two.) A. The architecture must provide access to a precision time protocol (PTP) for time synchronization. B. The architecture must report on system usage in terms of CPU, memory, storage and network. C. The architecture must support class three (Three nines or 99.9%) system availability. D. The architecture must support tracking of administrative logons and actions. E. The architecture must provide for system recovery point objective (RPO) of two hours. Answer: C, E Explanation: The architecture must support class three (three nines or 99.9%) system availability. This requirement focuses on the availability of the system, which is a business goal related to ensuring that the system is operational for a specified percentage of time (99.9% uptime). It is a high- level operational requirement that is tied to business continuity and meeting customer service expectations. The architecture must provide for system recovery point objective (RPO) of two hours. The RPO is a business requirement related to disaster recovery. It specifies how much data loss is acceptable in the event of a failure. This requirement ensures that business processes are protected by minimizing the potential impact of data loss, making it a key business consideration. 4.An architect is designing a new vSphere 8 environment and needs to plan the migration of virtual machines from the source vSphere 7 infrastructure. The following has been captured about the source infrastructure and project: All virtual machines operate supported versions of Microsoft Windows All virtual machines have VMware Tools 11 or higher installed vCenter Enhanced Linked Mode is configured VMware PowerCLI is available in the environment No budget is available for discovery tooling The architect must capture and review active services from inside running virtual machines to inform the migration design. Considering the information available, which method can the architect use to acquire the information required? A. Request and review the information via VMware vCenter B. Deploy and review the service information from VMware Aria Operations C. Deploy and review the service information from VMware Aria Operations for Applications D. Request and review the information via VMware Tools and VMware PowerCLI Answer: D Explanation: Given that VMware Tools 11 or higher is installed on all virtual machines and VMware PowerCLI is available in the environment, the architect can leverage PowerCLI to interact with VMware Tools and collect information about active services running inside the virtual machines. VMware PowerCLI allows you to query virtual machines for information about their services by accessing the guest operating system, provided VMware Tools is installed and running. You can use PowerCLI cmdlets to retrieve service data, such as which services are running on the VM, their statuses, and other details necessary for planning the migration. This option is cost-effective since there is no budget available for additional discovery tooling, and it aligns well with the existing tools and infrastructure already in place. 5.An architect is updating the design for a vSphere environment. During a workshop focused on security, the following has been identified: It has been determined that any configuration of ESXi hosts can only be completed via VMware vCenter The Direct Console User Interface (DCUI) service must be disabled on ESXi hosts The SSH service must be disabled on ESXi hosts Based on the information from the workshop, which element does the architect need to include in the design? A. Strict Lockdown Mode B. Normal Lockdown Mode C. Normal Lockdown Mode with a defined Exception User list D. Strict Lockdown Mode with a defined Exception User list Answer: A Explanation: Strict Lockdown Mode is the correct choice because it restricts all access to the ESXi host directly, ensuring that configuration can only be performed through VMware vCenter. This is in line with the requirement that configuration can only be done via vCenter. Strict Lockdown Mode disables the Direct Console User Interface (DCUI) and SSH services, which aligns with the customer's requirement to have these services disabled for security purposes. 6.An architect is documenting the logical design for a new vSphere solution. The following requirements have been provided to the architect by the customer for the design: The solution must be deployed in two locations: DC1 and DC2 The solution must limit the impact radius of accidental changes by administrators The solution must meet a recovery time objective (RTO) of four (4) hours and recovery point objective (RPO) of 24 hours The solution must allow workloads to run in both DC1 and DC2 during normal operations The solution must allow workloads to be moved bi-directionally between DC1 and DC2 The solution must use hyper-converged infrastructure for the virtual machine storage The customer has also confirmed that the network connection between DC1 and DC2 has a 10 Gbps bandwidth with a maximum round trip latency of 4 ms. The architect recommends the following design decision: Use separate clusters in DC1 and DC2 to form a multi-region design What should the architect include as justification for this design decision? A. Sufficient capacity must be deployed in both DC1 and DC2 to support all running virtual machines. B. Using separate clusters mitigates the risk of an accidental change at the cluster level in DC1 from impacting DC2. C. Using separate clusters is the only configuration available that supports the RTO of four (4) hours. D. The network connection between DC1 and DC2 does not support the use of stretched clusters. Answer: B Explanation: Separate clusters in DC1 and DC2 provide logical isolation between the two data centers. This means that an accidental change or misconfiguration in one cluster (e.g., DC1) will not affect the other cluster (e.g., DC2). This isolation meets the customer's requirement to limit the impact radius of accidental changes by administrators. By having separate clusters, the risk of cross-site or cross-cluster disruptions is minimized, ensuring better fault tolerance and administrative control. 7.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 B 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 spread 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 (Vendor A) servers will be deployed to the primary site and both the Intel-based and AMD- based servers (Vendor B) will be deployed to the secondary site. Which assumption should the architect make to support the lifecycle management of vSphere 8? A. The different processor architectures across both sites will remediate against a shared vSphere Lifecycle Manager baseline. B. The different processor architectures will be located in the same cluster to support vSphere Lifecycle Manager image-based remediation. C. The different processor architecture within a single site will remediate against a single vSphere Lifecycle Manager image. D. The different processor architectures across both sites will remediate against a single vSphere Lifecycle Manager image. Answer: C Explanation: vSphere Lifecycle Manager (vLCM) is used to manage ESXi host configurations and software versions in a consistent and streamlined manner. In this case, the architect needs to account for the heterogeneous hardware across two sites (Intel and AMD-based servers). Since Intel and AMD processors are incompatible for remediation with a single vSphere Lifecycle Manager image, the different processor architectures should be grouped by site (not across sites). Within each site, vLCM can manage a single image per processor architecture, ensuring that each site’s hosts with compatible processors are remediated consistently. Intel-based servers will be managed with one image and AMD-based servers with another image, but they can be managed in separate sites. This approach avoids the issue where heterogeneous hardware with different processor types would need separate images. By keeping them within the same site, the architecture simplifies the lifecycle management and meets the requirement for minimizing clusters and ensuring service availability during upgrades. 8.What are two valid use cases for VMware Cloud Foundation remote clusters? (Choose two.) A. Provide disaster recovery for an existing workload domain. B. Enable vSphere with Tanzu on a cluster deployed at a remote location. C. Provide resources for virtual machines at an edge location. D. Transform virtual machines to vSphere with Tanzu containers. E. Deploy a cluster within the same rack as the central VMware Cloud Foundation instance. Answer: B, C Explanation: Enable vSphere with Tanzu on a cluster deployed at a remote location. VMware Cloud Foundation remote clusters can be deployed to extend the functionality of vSphere with Tanzu to remote locations. This allows for containerized workloads to be managed and orchestrated using the same tools as the primary environment, providing consistent management of Tanzu clusters across multiple sites. Provide resources for virtual machines at an edge location. Remote clusters can be deployed at edge locations to provide computing resources for workloads that need to run close to the data source. This use case is particularly useful for applications that require low latency or need to process data locally before sending it to the central cloud infrastructure. 9. Host Calculation: Production Workloads (750 vCPUs per site): - 750 vCPUs for production divided by 240 vCPUs per host = 3.125 hosts (rounding up = 4 hosts per site for production). Development Workloads (200 vCPUs): - 200 vCPUs divided by 480 vCPUs per host = 0.416 hosts (rounding up = 1 host for development). 10.A company has a requirement that all production applications must have a maximum tolerable downtime (MTD) of one hour per month. Which statement would be included in the conceptual design to support this requirement? A. Production applications will run in a dedicated Tier 2 cluster. B. Server hardware has been allocated for the production applications. C. vSphere Fault Tolerance (FT) will not be enabled for the production applications. D. vSphere HA Host Failure Response will be set to Restart VMs. Answer: B Explanation: To meet the requirement of maximum tolerable downtime (MTD) of one hour per month, the system must ensure that in the event of a host failure, the production applications (virtual machines) are restarted as quickly as possible. Configuring vSphere HA Host Failure Response to Restart VMs ensures that VMs are automatically restarted on available hosts in the cluster if a host failure occurs. This setup minimizes downtime and ensures that the system can recover within the specified MTD of one hour per month. 11.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. Which three additional design decisions should the architect make to meet these requirements? (Choose three.) 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. Answer: 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. 12.An architect is designing a new vSphere solution. The solution will be used to host workloads that have multiple dependencies. The customer provides the following information regarding the workloads: Workload 1: Self-Service Portal Workload 2: Database Workload 3: Identity Broker Workload 4: Reporting Tool Workload 5: Management Tool Application A is formed of workloads 1 and 2 and has a dependency on workload 3 Application B is formed of workloads 2 and 4 and has a dependency on workload 3 Application C is formed of workload 5 and has a dependency on workload 4 How should the architect document the vSphere HA requirements to ensure that all of the applications can be recovered in the event of a host failure while observing the dependencies? A. Set vSphere HA to Restart VMs in response to a Host Failure Set the Restart Priority of workload 3 to High Set the Restart Priority of workload 4 to Medium Set the Restart Priority of workloads 1, 2 and 5 to Low B. Set vSphere HA to Shut Down and Restart VMs in response to a Host Isolation Set the Restart Priority of workloads 3 and 4 to High Set the Restart Priority of workload 5 to Medium Set the Restart Priority of workloads 1 and 2 to Low C. Set vSphere HA to Restart VMs in response to a Host Failure Set the Restart Priority of workloads 3 and 4 to High Set the Restart Priority of workload 5 to Medium Set the Restart Priority of workloads 1 and 2 to Low D. Set vSphere HA to Shut Down and Restart VMs in response to a Host Isolation Set the Restart Priority of workload 3 to High Set the Restart Priority of workloads 4 and 5 to Medium Set the Restart Priority of workloads 1 and 2 to Low Answer: C Explanation: The goal here is to ensure that, in the event of a host failure, the workloads are restarted in the correct order based on their dependencies: Workload 3 (Identity Broker) is required by both Application A and Application B as a dependency. It needs to be set to High Restart Priority, ensuring that it is restarted before the other dependent workloads. Workload 4 (Reporting Tool) is required by Application B and Application C, so it should be set to High Restart Priority to ensure it is available before the other dependent workloads (like Workload 5). Workload 5 (Management Tool) is required by Application C and should have a Medium Restart Priority, meaning it will be restarted after Workload 4. Workloads 1 and 2 (Self-Service Portal and Database) have Low Restart Priority because they are dependent on Workload 3 (and Workload 4), but they do not have further critical dependencies after Workload 3, so they should be restarted last in the event of a failure. This setup ensures that all applications can be recovered properly in the event of a host failure, with each workload restarting in the correct order to maintain the application dependencies. 13.An architect is documenting the design for a new multi-site vSphere solution. The customer has informed the architect that the workloads hosted on the solution are managed by application teams, who must perform a number of steps to return the application to service following a failover of the workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The customer has provided the architect with the following information about the workloads: Critical workloads have a WRT of 12 hours Production workloads have a WRT of 24 hours Development workloads have a WRT of 24 hours All workloads have an RPO of 4 hours Critical workloads have an RTO of 1 hour Production workloads have an RTO of 12 hours Development workloads have an RTO of 24 hours The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of the development workloads until all critical and production workloads have been recovered at the secondary site. What would the architect document as the maximum tolerable downtime (MTD) for each type of workload in the design? A. Critical Workloads: 13 hours Production Workloads: 36 hours Development Workloads: 48 hours B. Critical Workloads: 13 hours Production Workloads: 36 hours Development Workloads: 60 hours C. Critical Workloads: 12 hours Production Workloads: 24 hours Development Workloads: 24 hours D. Critical Workloads: 16 hours Production Workloads: 28 hours Development Workloads: 28 hours Answer: A Explanation: The Maximum Tolerable Downtime (MTD) is the maximum time that an application or system can be unavailable before it negatively impacts the business. The MTD is calculated by adding the Recovery Time Objective (RTO) to the Work Recovery Time (WRT). Here’s how it applies to each workload type: - Critical Workloads: - RTO: 1 hour (time to restore the system to a usable state after failure). - WRT: 12 hours (the time to get the application fully back to service). - MTD = RTO + WRT = 1 hour + 12 hours = 13 hours. - Production Workloads: - RTO: 12 hours (time to restore the system to a usable state after failure). - WRT: 24 hours (time to get the application fully back to service). - MTD = RTO + WRT = 12 hours + 24 hours = 36 hours. - Development Workloads: - RTO: 24 hours (time to restore the system to a usable state after failure). - WRT: 24 hours (time to get the application fully back to service). - MTD = RTO + WRT = 24 hours + 24 hours = 48 hours. 14.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 Answer: 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. 15.Refer to the exhibit. An architect is assigned a new project to design a VMware hybrid cloud solution. The project is following a proven design methodology following the V-Model of systems engineering and verification. The selected methodology follows these phases: Assess, Design, Deploy and Validate. Which activity would be conducted during the Design phase? A. The architect conducts a series of group interviews with stakeholders B. The architect helps stakeholders learn the mechanics of the solution C. The architect resolves configuration issues and addresses concerns D. The architect defines the scope of the project Answer: A Explanation: Design phase: The purpose of the Design phase is to define how the solution will meet the specific requirements. During this phase, the architect works closely with stakeholders to understand their needs and translate those needs into a technical design. A key activity in this phase often involves refining the solution details through interviews and discussions with key stakeholders to ensure that the design aligns with the business and technical requirements.
