A vSphere administrator enables and configures a Software iSCSI Initiator, and configures an

iSCSI vmkernel portgroup with Port Binding. The SAN administrator creates a few LUNs on an

iSCSI server. However, when the vSphere administrator adds the IP address of the iSCSI server

in the Dynamic Discovery list, no iSCSI targets are detected.

What condition would result in this behavior?


Options are :

  • A Software iSCSI Initiator cannot use Port Binding in conjunction with Dynamic Discovery.
  • The iSCSI server IP address should be entered in the Static Discovery instead of Dynamic Discovery list.
  • The iSCSI vmkernel portgroup and the iSCSI server are on different subnets. (Correct)
  • The network card bound to the iSCSI portgroup is 1Gbps Ethernet instead of 10Gbps

Answer : The iSCSI vmkernel portgroup and the iSCSI server are on different subnets.

A system administrator is deploying a Windows virtual machine from a template and needs the IP

  • Use the VMware Quickprep Tool.
  • Use the Microsoft Sysprep Tool. (Correct)

Answer : Use the Microsoft Sysprep Tool.

A Distributed Resource Scheduler (DRS) cluster is displaying a message that recommends the

migration of virtual machines, even though the cluster is currently balanced.

What is the likely reason for this?


Options are :

  • The DRS cluster does not satisfy the resource pool reservations. (Correct)

20GB. The datastore has 35GB of free space. The datastore is overcommitted by 95GB.

What is preventing the virtual machine from being built?


Options are :

  • Select a datacenter, create an HA Cluster, add resources to the cluster, configure HA-specific settings, and enable HA
  • Select a resource pool, create an HA Cluster in the resource pool, add resources to the cluster, configure HA-specific settings, and enable HA

Answer : Select a datacenter, create a cluster in the datacenter, add resources to the cluster, enable HA, and configure HA-specific settings

A vSphere administrator attempts to move a powered on virtual machine into a resource pool that

is configured in an HA/DRS cluster. The operation fails.

What condition would cause this behavior?


Options are :

  • The virtual machine was not powered off before being moved into the resource pool.
  • HA admission control prevented the movement of the virtual machine due to insufficient resources.
  • Resource pool admission control prevented the movement of the virtual machine due to insufficient resources. (Correct)

A SAN administrator recently installed a storage encryption switch on the Fibre Channel Fabric.

Shortly after the deployment, several new VMFS5 datastores recently created were dismounted.

Attempts to manually mount them fail. VMFS5 upgraded datastores are unaffected. All Storage

arrays in use support VASA and VAAI.

What is the root cause of this problem?


Options are :

  • All newly created VMFS5 datastores are tagged WRITE_SAME_Only. The storage encryption switch blocks the WRITE_SAME command.
  • All newly created VMFS5 datastores are tagged ATS_Only. The storage encryption switch blocks the ATS command. (Correct)
  • All newly created VMFS5 datastores were formatted with 1MB block size. The storage encryption switch does not support this block size.
  • All newly created VMFS5 datastores are tagged XCOPY_Only. The storage encryption switch blocks the XCOPY command.

Answer : All newly created VMFS5 datastores are tagged ATS_Only. The storage encryption switch blocks the ATS command.

An administrator removes a virtual machine from a resource pool and places it in the DRS root

resource pool. Users report the performance of the application running on the virtual machine has

improved. The virtual machine relocation was the only change that occurred.

What explains the change in application performance?


Options are :

  • The memory, storage, and/or CPU settings of the original resource pool restricted access to resources for the virtual machine. (Correct)
  • The configured memory, storage and/or CPU shares on the root resource pool are higher than the original resource pool.
  • The configured memory storage and/or CPU reservations on the root resource pool are higher than the original resource pool.
  • The memory, storage and/or CPU settings on the root resource pool restricted access to resources for the virtual machine

Answer : The memory, storage, and/or CPU settings of the original resource pool restricted access to resources for the virtual machine.

  • Decrease the memory allocation for the virtual machine.
  • Increase the share value for the resource pool.
  • Increase the memory resource allocation to the resource pool.
