VMware 3V0-21.21 Exam : Advanced Design VMware vSphere 7.x

Application owners require support of a Microsoft Windows Server Failover Cluster (WSFC).
Their current environment consists of the following components:
vSphere 7.0 and vSAN 7.0
External array supporting NFS 3.0/4.1, Server Message Block (SMB) 2.1
10 GbE storage connectivity for all devices
The solution architect is tasked with coming up with a solution to meet this requirement while utilizing their existing investments.
Which two recommendations could the architect make? (Choose two.)

• A. Use NFS 4.1 shares for quorum and shared disk
• B. Use vSAN native support for WSFC
• C. Use the SMB 2.1 protocol for sharing disks
• D. Use raw device mapping (RDM)
• E. Run WSFC on vSAN iSCSI Target Service

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.)

• A. Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.
• B. Add a precision clock virtual device to each virtual machine running the application.
• C. Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
• D. Use a Linux distribution as the guest operating system.
• E. Configure the chrony time-sync agent on each virtual machine guest operating system.
• F. Use Microsoft Windows Server as the guest operating system.

Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company's licenses will not be renewed for cost-savings related to the acquisition. All consumed vSphere licenses must have active support to support line-of-business operations. The merged environment must maintain 25% spare capacity. The architect has a small budget remaining unallocated for hardware.
The architect has calculated that the current vSphere environment can absorb the acquired company's virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.
Which design decision can the architect make to incorporate the new company's virtual machines into the combined vSphere environment?

• A. Use the current budget to add memory to the cluster to increase each ESXi host's capacity and add the new virtual machines.
• B. Purchase extra hosts to add to the cluster in anticipation of adding the acquired company's virtual machines.
• C. Purchase new licenses for some of the acquired company's ESXi hosts and add them to the cluster to hold the acquired company's virtual machines.
• D. Migrate the acquired company's virtual machines into the vSphere environment as it will currently fit.

A new vSphere platform is being created. The platform will host virtual machines that will run management services and line-of-business applications.
What should the architect consider when designing the number and type of clusters required?

• A. Maximum tolerable downtime
• B. Auditing requirements for the virtual machines
• C. The level of isolation required between virtual machine classifications
• D. Predicted platform growth

An architect is designing a VMware software-defined data center (SDDC) solution based on the following customer requirements:
The solution must initially support 1,000 virtual machines
The solution must scale to support the concurrent running of up to 5,000 virtual machines The production environment should be delivered across two data centers The solution should have a maximum tolerable downtime (MTD) of four hours The solution should have a monthly service availability target of 99.8% Which two assumptions could the architect make based on the information from the customer to help size the solution? (Choose two.)

• A. The number of vSphere hosts in a cluster
• B. The size (CPU/RAM/storage) of the vSphere hosts
• C. The average resource utilization of a virtual machine
• D. The guest operating system for each virtual machine
• E. The size (CPU/RAM/storage) of the average virtual machine
