VMware 2V0-620 Online Questions & Answers

• Question 131:

  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.
  A. Select a valid name.
  D. Select the virtual machine compatibility.

  ---

  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 132:

  Which two configurable options apply to both virtual machine CPU and memory allocation? (Choose two.)

  A. Reservation
  B. Shares
  C. Resource Pool
  D. Reserve All
  A. Reservation
  B. Shares

  ---

  Reservation and shares apply to virtual machine CPU and memory allocation. Reference: http://frankdenneman.nl/2010/06/08/reservations-and-cpu-scheduling/

• Question 133:

  Which vSphere 6.x feature will allow an organization to utilize native snapshots?

  A. Virtual Volumes
  B. Virtual SAN
  C. VMFS3
  D. VMFS5
  A. Virtual Volumes

  ---

  Virtual Volumes has the following characteristics:

  Virtual Volumes supports offloading a number of operations to storage hardware. These operations include snapshotting, cloning, and Storage DRS.

  With Virtual Volumes, you can use advanced storage services that include replication, encryption, deduplication, and compression on individual virtual disks.

  Virtual Volumes supports such vSphere features as vMotion, Storage vMotion, snapshots, linked clones, Flash Read Cache, and DRS.

  With Virtual Volumes, storage vendors can use native snapshot facilities to improve performance of vSphere snapshots.

  You can use Virtual Volumes with storage arrays that support vSphere APIs for Array Integration (VAAI).

  Virtual Volumes supports backup software that uses vSphere APIs for Data Protection (VADP).

• Question 134:

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

  ---

  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 135:

  What are two possible causes of Storage Distributed Resource Scheduler (SDRS) being disabled on one or more virtual machine disks in a datastore cluster? (Choose two.)

  A. The virtual machine has vSphere Fault Tolerance disabled.
  B. The virtual machine is a template.
  C. The virtual machine swap file is on a shared datastore.
  D. The disk is a CD-ROM/ISO file.
  B. The virtual machine is a template.
  D. The disk is a CD-ROM/ISO file.

  ---

  Possible causes of SDRS being disabled might be related to the fact that the virtual machine is a template or the disk is a CD-ROM or an ISO file.

• Question 136:

  An administrator needs to verify that vMotion operations can be performed in a vSphere data center.

  What round trip time (RTT) latency is the maximum value that will allow vMotion operations to succeed?

  A. 50ms RTT
  B. 100ms RTT
  C. 150ms RTT
  D. 200ms RTT
  C. 150ms RTT

• Question 137:

  A Fault Tolerance (FT) virtual machine with four vCPUs is experiencing high latency when performing ICMP and Application tests. What are three potential causes that may be attributing to this latency? (Choose three.)

  A. The FT network has insufficient bandwidth and is running on a 1GB Link.
  B. The FT network is on a particularly high latency link.
  C. The FT network has been configured with Network I/O Control.
  D. The FT virtual machine is running an e1000 network adapter.
  E. The FT virtual machine is running on poor performing network-based storage.
  A. The FT network has insufficient bandwidth and is running on a 1GB Link.
  B. The FT network is on a particularly high latency link.
  C. The FT network has been configured with Network I/O Control.

  ---

  The latency can be caused by FT network having insufficient bandwidth and is running on a 1 GB link or the network is on a particularly high latency risk. The other reason might be that the FT network has been configured with network I/O control.

• Question 138:

  Which two actions are required when enabling vFlash Read Cache for a virtual machine's virtual disk? (Choose two.)

  A. A value in the Virtual Flash Read Cache text box must be entered.
  B. A Flash Resource Pool for Cache size reservation must be entered.
  C. The Device backing and the block size must be configured.
  D. The Enable virtual flash host swap cache check box must be selected.
  A. A value in the Virtual Flash Read Cache text box must be entered.
  D. The Enable virtual flash host swap cache check box must be selected.

  ---

  To enable vFlash Read cache for VM virtual disk, enter a value in virtual flash read cache text box and enable virtual flash host swap ache check box. Reference: http://www.yellow-bricks.com/2013/08/26/introduction-to-vsphere-flash-read-cache-aka-vflash/

• Question 139:

  An administrator is installing a new network card in an ESXi 6.x host that is part of a vSphere cluster. When the host is placed into maintenance mode, the vSphere Web Client displays the progress bar at 2% for over 30 minutes. Which two are likely reasons for this occurrence? (Choose two.)

  A. Maintenance mode is unable to migrate all virtual machines from the host.
  B. There is a large number of virtual machines that must be migrated from the host.
  C. VMware High Availability is in the process of reconfiguring the cluster.
  D. Each virtual machine on the ESXi host must be reconfigured to recognize the new adapter.
  A. Maintenance mode is unable to migrate all virtual machines from the host.
  B. There is a large number of virtual machines that must be migrated from the host.

  ---

  The maintenance mode is unable to migrate all virtual machines from the host. There is a large number of VM s that must be migrated first. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=1005241

• Question 140:

  An organization has a number of virtual machines that would benefit from Fault Tolerance. These include: A single vCPU Apache Server A dual vCPU vCenter Server A quad vCPU SQL Server An eight vCPU Hadoop Server

  Which two virtual machines can be configured to use VMware Fault Tolerance? (Choose two.)

  A. Apache Server
  B. vCenter Server
  C. SQL Server
  D. Hadoop Server
  A. Apache Server
  C. SQL Server

  ---

  Apache server and SQL server can be configured to use VMware fault tolerance.
