VMware 2V0-620 Online Questions & Answers

• Question 81:

  Which scenario shows a reason for VMware Tools failing to install?

  A. Virtual machine has a CD-ROM configured.
  B. Guest OS Antivirus is blocking the VMware Tools installation.
  C. Guest OS has 64-bit ldd (list dynamic dependencies) utility installed.
  D. Virtual machine is powered on.
  B. Guest OS Antivirus is blocking the VMware Tools installation.

  ---

  One of the reasons for VMware tools to fail during installation is that the Guest OS antivirus is blocking the installation thinking it is a malware.

  A. Storage Distributed Resource Scheduling
  B. High Availability
  C. Fault Tolerance
  D. Distributed Resource Scheduling
  E. Virtual SAN
  B. High Availability
  D. Distributed Resource Scheduling
  E. Virtual SAN

  ---

  On a nw host cluster, high availability, distributed resource scheduling and virtual SAN can be enabled.

• Question 83:

  An administrator receives a report that no real time statistics are available for a virtual machine in the vCenter Server inventory. Which two statements indicate likely causes of the problem? (Choose two.)

  A. The virtual machine is powered off.
  B. The host containing the virtual machine is disconnected from vCenter Server.
  C. There is insufficient real time data to display the information.
  D. The vCenter Server service is not running.
  A. The virtual machine is powered off.
  B. The host containing the virtual machine is disconnected from vCenter Server.

  ---

  The most likely cause might be that the virtual machine is powered off or the host containing the VM is disconnected from the vCenter server. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=1003979

• Question 84:

  You are editing the management network configuration of an ESXi 6.x Host from the vSphere Web Client. You mistakenly put the incorrect VLAN in place for the management network. What action do you need to take to correct this?

  A. You need to manually edit the configuration on the host with command line utilities.
  B. No action is required. By default ESXi rolls back configuration changes that disconnect the host.
  C. The ESXi host system configuration will need to be restored to the factory configuration to fix the issue.
  D. The change can be reverted in the vSphere Web Client by simply editing the switch again.
  B. No action is required. By default ESXi rolls back configuration changes that disconnect the host.

  ---

  Host networking rollbacks occur when an invalid change is made to the host networking configuration. Every network change that disconnects a host also triggers a rollback. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=2032908

• Question 85:

  After installation of a host in your test environment, you need to move it to production. The only major change that needs to be made is that the hostname of the server needs to change. What are two ways that an administrator can change the host name without editing configuration files on the host directly? (Choose two.)

  A. Login to the Direct Console User Interface and change it from here.
  B. Edit the Default TCP/IP Configuration from the vSphere Web Client.
  C. Use the Ruby vSphere Client to send a script to the ESXi host that updates the hostname.
  D. Update the information in DNS and the ESXi host will automatically update with these changes.
  A. Login to the Direct Console User Interface and change it from here.
  B. Edit the Default TCP/IP Configuration from the vSphere Web Client.

  ---

  To change the host name without editing configuration files on the host, first, login to the direct console user interface and change the host name. Now edit the default TCP/IP configuration from the vSphere client. Reference: http://pubs.vmware.com/vsphere-60/index.jsp

• Question 86:

  What is true regarding datastores on ESXi 6.x?

  A. NFS 4.1 datastore does not support Fault Tolerance (FT)
  B. Both VMFS3 and VMFS5 datastores can be created
  C. NFS datastore can be mounted using NFS 4.1 on one ESXi host and NFS 3.0 on another
  D. NFS 3.0 datastore does not support Fault Tolerance (FT)
  A. NFS 4.1 datastore does not support Fault Tolerance (FT)

  ---

  VMs on NFS v4.1 support FT, as long as it is the new FT mechanism introduced in 6.0. VMs running on NFS v4.1 do not support the old, legacy FT mechanism.

  In vSphere 6.0, the newer Fault Tolerance mechanism can accommodate symmetric multiprocessor (SMP) virtual machines with up to four vCPUs. Earlier versions of vSphere used a different technology for Fault Tolerance (now known as legacy FT), with different requirements and characteristics (including a limitation of single vCPUs for legacy FT VMs). Reference: http://vsphere-land.com/news/nfs-4-1-support-in-vsphere-limitations-and-caveats.html

• Question 87:

  What may be a cause for failure to unmount an NFS datastore?

  A. It has active snapshot files.
  B. It is being used for High Availability (HA) heartbeat.
  C. It is part of a Cluster.
  D. It is managed by Distributed Resource Scheduler (DRS).
  B. It is being used for High Availability (HA) heartbeat.

  ---

  vSphere HA heartbeating does not prevent you from unmounting the datastore. If a datastore is used for heartbeating, unmounting it might cause the host to fail and restart any active virtual machine. If the heartbeating check fails, the vSphere Client displays a warning. Reference: https://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.storage.doc_50%2FGUID-1B56EF97-F60E-4F21-82A7-8F2A7294604D.html

• Question 88:

  An administrator has just completed performing an interactive installation of ESXi 6.x and is booting the host.

  How is the network initially configured?

  A. The network is configured by Automatic Private IP Addressing (APIPA).
  B. The network is configured based on the settings detected in DNS.
  C. The network is configured with the address as specified in the installer.
  D. The network is automatically configured by DHCP.
  D. The network is automatically configured by DHCP.

• Question 89:

  An administrator is configuring the Failover Order option on a vSphere Distributed Switch. Which two options should be used with IP-hash load balancing? (Choose two.)

  A. Active Uplinks
  B. Standby Uplinks
  C. Unused Uplinks
  D. Override Failover Order
  A. Active Uplinks
  C. Unused Uplinks

  ---

  Active Uplinks, and Unused adapter Uplinks are used with IP hash load balancing. Reference: https://books.google.com.pk/books?id=35TE4cSycNACandpg=PA201andlpg=PA201anddq=IP+hash+load+balancing+active+uplinks+unused+uplinksandsource=blandots=ggg8VOCpw4andsig=EaqvN49p2UWQ5b6V53SkFFmJhcandhl=enandsa=Xandved=0ahUKEwiv1ruEhMbNAhVGL48KHfXaBN4Q6AEIUzAJ#v=onepageandq=IP%20hash%20load%20balancing%20active%20uplinks%20unused%20uplinksandf=false

• Question 90:

  An administrator has configured an alarm to be notified when a virtual machine meets either of these conditions:

  High virtual CPU

  High active memory consumption.

  The alarm is only triggering when both of the conditions are met.

  What can be done to correct the alarm behavior?

  A. Edit the alarm and select Trigger if ANY of the following conditions are satisfied.
  B. Edit the alarm and select Trigger if ALL of the following conditions are satisfied.
  C. Create two separate alarms, one for CPU and one for memory and link them together with ESXCLI.
  D. Delete the existing alarm and create a new event based alarm.
  A. Edit the alarm and select Trigger if ANY of the following conditions are satisfied.

  ---

  Edit the alarm and select Trigger if All of the following conditions are satisfied.
