Which memory conservation technique allows the secure elimination of redundant copies of memory pages between virtual machines on the host?
A. VMkernel Swap
B. Memory Balloon Driver
C. RAM Overcommit
D. Transparent Page Sharing
What would cause the proportional share mechanism to be invoked?
A. there is resource contention
B. CPU ready time exceeds a threshold
C. More than 1 virtual machine is running
D. the sum of reservations exceeds the physical resources
A storage array containing a VMFS datastore must be taken offline for maintenance. What can be done to avoid virtual machine downtime on VMs running in this datastore?
A. Clone the virtual machines to a VMFS datastore on a different storage array.
B. Use Site Recovery Manager to failover the virtual machines on the storage array to the recovery site.
C. Use vSphere HA to failover the virtual machines to ESX Servers attached to a different storage array.
D. Use Storage VMotion to migrate the virtual machines to a VMFS datastore on a different storage array.
An administrator has a mixture of Intel-based ESX Hosts in a DRS cluster where the CPUs are compatible in every way except that some support the NX/XD feature and some do not. Which two actions will minimize the effect of these differences? (Choose two.)
A. Mask the NX/XD bit in the Processor section of the Configuration tab on the ESXi hosts
B. Mask the NX/XD bit on every virtual machine in the cluster
C. Enable Enhanced VMotion Compatibility
D. Enable Rapid Virtualization Indexing
An administrator determines that a virtual machine configured for the Development port group lost network connectivity when it was migrated with vMotion from one ESXi 5.x host to another. The administrator notices that machines configured for the Production port group are not experiencing the issue. The hosts have port groups with the following network configuration:
Production (VLAN 100)
Production (VLAN 100)
Development (VLAN 200)
Which two conditions would explain the loss of network connectivity for the virtual machine? (Choose two.)
A. The configured VLAN for Production on Host A is incorrect.
B. The configured VLAN for Development on Host B is incorrect.
C. An improper native VLAN is configured on the uplinks to Host A.
D. An improper native VLAN is configured on the uplinks to Host B.
What protocol is used by an ESXi host to communicate with NAS devices?
Which two conditions will cause a vMotion validation check to fail? (Choose two.)
A. An active connection that matches an existing port group label on the target host
B. Insufficient network bandwidth on the target virtual switch
C. Different security policies on the target virtual switch
D. An active connection to an internal virtual switch
Which condition produces a warning message but will allow a VMotion migration to proceed?
A. A virtual machine has an active connection to the ESXi host’s CD-ROM drive
B. A virtual machine has a CPU affinity set to run on a specific CPU.
C. A virtual machine is in an MSCS Cluster relationship with another virtual machine
D. A virtual machine is configured to use an internal virtual switch but is not connected to the switch
An administrator must perform maintenance on a fibre channel switch connected to vmhba2 on an ESXi host. The ESXi host has been configured with the Fixed policy, and the preferred path will be impacted by the maintenance event. Which procedure is the least disruptive option that can be taken to prepare for the maintenance event?
A. Change the policy on the ESXi host to MRU for the duration of the maintenance event
B. Use the vSphere Client to disable the path impacted by the maintenance event
C. Unplug the FC cable from vmhba2 for the duration of the maintenance event
D. Unplug the FC cable from the Storage Processor port on the FC array for the duration of the
which of these statements are true about vSwicth uplinks?
A. vSwitch can be configured without uplink
B. vswitch can not be configured without uplink
C. vswitch can be configured with multiple uplinks
D. vswitch can not be configured with multiple uplinks
