• Question 132:

  Which method provides the best performance for the lowest resource cost when building a virtual machine for a single-threaded Windows application?

  A. Deploy single-threaded applications on uniprocessor virtual machines.

  B. Deploy single-threaded applications on symmetric multi-processor virtual machines.

  C. Tune single-threaded applications to take advantage of symmetric multi-processor resources.

  D. Tune Single-threaded applications at the hypervisor level.

  Correct Answer: A

  Virtual processors are not supported. You have to deploy single threaded applications on uniprocessor virtual machines. Reference: http://support.theenterprisecloud.com/kb/default.asp?id=343

• Question 133:

  What is a limitation of this configuration?

  A. Devices must be reserved for PCI passthrough on at least one host on which the virtual machine will run.

  B. Snapshots are not supported with DirectPath I/O devices.

  C. A maximum of 18 PCI DirectPath I/O devices can be added to a virtual machine.

  D. Only one PCI controller can be presented to the virtual machine.

  Correct Answer: B

  Snapshots are not supported with PCI vSphere Direct Path I/O devices.

• Question 134:

  An ESXi 6.x host consists of 24 logical cores. Hyperthreading is enabled on the host.

  What is the maximum number of vCPUs that can be assigned to a virtual machine on this host?

  B. 48

  C. 64

  D. 128

  Correct Answer: A

  A total of 24 vCPUs can be assigned to a virtual machine if hyperthreading is enabled.

• Question 135:

  An administrator is deploying multiple Windows 2003 Virtual Machines from the same template.

  What two steps should be taken to avoid network conflicts? (Choose two.)

  A. Customize the guest operating system.

  B. Install VMware Tools into the new virtual machines.

  C. Copy the Microsoft Sysprep tools onto the vCenter Server system.

  D. Ensure the e1000 vmnic is selected for each new virtual machine.

  Correct Answer: AC

  To avoid such network or software conflicts, its recommended to customize the VM Guest during the deployment process. For Guest OS customization of virtual machines deployed from templates, vCenter requires the following:

  If the guest OS is Windows, you need VMware Tools and Sysprep utils to be installed within the templates: You will need to copy Sysprep tools to vCenter for Windows 2000, XP and 2003. Starting with Windows Vista onward, Sysprep tools are part of the base OS install.

• Question 136:

  From which two locations in the inventory hierarchy can you deploy a virtual machine using a template? (Choose two.)

  A. Directly from the template.

  B. From a compute resource.

  C. From an existing virtual machine.

  D. From a Datastore.

  Correct Answer: AB

  You can deploy a virtual machine directly from the template. A compute resource can also be used for deploying a VM. Reference: https://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenterserver-60-virtual-machine-admin-guide.pdf

• Question 137:

  You are creating a virtual machine in the Web Client using the New Virtual Machine wizard. Which two steps are required? (Choose two.)

  A. Select a valid name.

  B. Select a cluster for the compute resource.

  C. Select a network adapter.

  D. Select the virtual machine compatibility.

  Correct Answer: AD

  When you create a virtual machine, you provide a unique name for it. The unique name distinguishes it

  from existing virtual machines in the virtual machine folder or datacenter. The name can contain up to 80

  characters. You can select a datacenter or folder location for the virtual machine, depending on your

  organizational needs.

  You can accept the default ESXi host version for this virtual machine or select a different version,

  depending on the hosts in your environment.

• Question 138:

  Refer to the Exhibit.

  

  A vSphere 6.x Standard Switch is configured with 4 virtual machine portgroups, as shown in the exhibit. Which portgroup would be utilized by default when creating a new virtual machine?

  A. Access Network

  B. DMZ Network

  C. VM Network

  D. Virtual Machine Network

  Correct Answer: A

  Access network will be utilized by deault when creating a new virtual machine as can be seen in the exhibit.

• Question 139:

  When is it possible to place a VMFS5 datastore in maintenance mode?

  A. When it is a member of a Storage DRS cluster

  B. When it is a member of Virtual SAN cluster

  C. When it is a member of a multi-extent datastore

  D. When it is a member of a Virtual Volume

  Correct Answer: A

  Storage DRS introduced the feature Datastore Maintenance mode and this new feature can be compared to Host Maintenance Mode. When a datastore is placed in Maintenance Mode all registered virtual machines on that datastore, are migrated to the other datastores in the datastore cluster. Datastore maintenance mode can be used to safely migrate virtual machines out of the datastore for storage array related maintenance operations such as migrating a LUN to another RAID group, however it is also an excellent feature that can help you during a storage migration project migrating virtual machines from standalone VMFS3 datastores to VMFS5 datastores aggregated in a Storage DRS datastore cluster.

• Question 140:

  Which three conditions would prevent Storage I/O Control from being enabled on a group of datastores? (Choose three.)

  A. The datastores planned for the solution are used by different vSphere clusters.

  B. A datastore planned for the solution is configured as a Raw Device Mapping file.

  C. A datastore planned for the solution has three extents.

  D. A datastore planned for the solution is configured as NFS.

  E. The organization has an Enterprise license.

  Correct Answer: BCE

  Datastore planned for solution is configured as RDM file. When the datastore has three extents and the organization has an enterprise license, storage I/O control will not be enabled on a group of datastores.
