- B . In response to datastore accessibility failures, vSphere HA restarts VMs on unaffected hosts.
- C . vSphere HA performs load balancing across the hosts in a cluster to prevent resources contention
- D . By Keeping a secondary VM running at all times, vSphere HA protects VMs from data loss.
- E . When vCenter Server experiences downtime, vSphere HA restarts VMs on unaffected hosts.
Which file system protocol is supported by vSphere?

An operator must deploy three virtual machines from a template named Win10-Template, and all three VMs must be configured with unique computer names.
Which action must the operator take to achieve this goal?
- A . Clone Win10-Template three times, and then change the computer name in each clone.
- B . Export Win10-Template to the local filesystem, and then change the computer name.
- C . Use a Windows 10 customization specification when deploying the virtual machines.
- D . Create the virtual machines using the New virtual Machine wizard.
Which virtual machine (VM) problem is solved using vSphere Storage vmotion?
- A . The ESXi host on which a VM is running requires to enter maintenance mode.
- B . The storage array on which a VM is running requires to enter maintenance mode.
- C . VMs are running on one ESXi host that presents high CPU resource contention.
- D . The vSphere Client shows that a VM needs to be consolidated.
An administrator has been tasked with associating multiple uplink adapters with a single switch that will share the load traffic.
Which networking feature should the administrator configure?
- A . Distributed Port Group
- B . Host Proxy Switch
- C . NIC Teaming
- D . VLAN
A system administrator is preparing a host In a vSphere DRS cluster in partially automated mode for firmware patching and puts a host into maintenance mode. After several minutes, the host still has not entered maintenance mode.
How should the system administrator resolve this problem?
- A . The system administrator needs to schedule DRS to run again.
- B . vSphere Lifecycle Manager and DRS integration need to be configured.
- C . vSphere HA admission control needs to be enabled on the cluster.
- D . The system administrator needs to migrate virtual machines using vSphere vMotion.
Which piece of information does vSphere DRS consider when making decisions about which host to place a virtual machine?
- A . Network bandwidth on the host
- B . Disk usage by the virtual machine
- C . Storage bandwidth on the host
- D . Network usage by the virtual machine
