VMware VMware Certifications 2V0-620 Questions & Answers

• Question 111:

  What are three goals of resource management within a cluster? (Choose three.)

  A. To prevent virtual machines from monopolizing resources and to guarantee predictable service rates.

  B. To exploit undercommitted resources and overcommit with graceful degradation.

  C. To provide solutions to potential problems that you might encounter when using vCenter Server.

  D. To control the relative importance of virtual machines and provide flexible dynamic partitioning.

  E. To provide additional network administration capabilities.

  Correct Answer: ABD

  When managing your resources, you should be aware of what your goals are.

  In addition to resolving resource overcommitment, resource management can help you accomplish the

  following:

  Performance Isolation--prevent virtual machines from monopolizing resources and guarantee predictable

  service rates.

  Efficient Utilization--exploit undercommitted resources and overcommit with graceful degradation.

  Easy Administration--control the relative importance of virtual machines, provide flexible dynamic

  partitioning, and meet absolute service-level agreements.

• Question 113:

  Which two statements are correct when turning off a Distributed Resource Scheduler (DRS) Cluster? (Choose two.)

  A. The resource pool hierarchy of the DRS cluster is maintained.

  B. The resource pool hierarchy of the DRS cluster is removed.

  C. The affinity settings of the DRS cluster are removed and not maintained when DRS is re-enabled.

  D. The affinity settings of the DRS cluster are maintained when DRS is re-enabled.

  Correct Answer: BC

  When DRS is disabled, the cluster's resource pool hierarchy and affinity rules are not reestablished when DRS is turned back on. So if you disable DRS, the resource pools are removed from the cluster. Reference: http://www.vladan.fr/vcp6-dcv-objective-9-2-configure-advanced-vsphere-drs-features/

• Question 114:

  An administrator creates a DRS cluster of eight ESXi 6.x hosts. There are 10 virtual machines balanced across the hosts. An attempt to place the first host into maintenance mode fails.

  What are two reasons that the host failed to enter maintenance mode? (Choose two.)

  A. The DRS cluster Automation Level is set to Partially Automated mode.

  B. One of the virtual machines on the ESXi Host entering maintenance mode is configured with a DRS Host affinity rule Should run on hosts in group.

  C. One of the virtual machines on the ESXi Host entering maintenance mode is configured with a DRS Host affinity rule Must run on hosts in group.

  D. One of the virtual machines on the ESXi Host entering maintenance mode is configured with an individual Automation Level set to Partially Automated.

  Correct Answer: AD

  When considering an automation level, it is usually best to choose Fully Automated and let DRS handle everything. However, when first enabling DRS, you might want to set the automation level to Manual or Partially Automated so that you can observe its recommendations for a while before turning it loose on Fully Automated. Even when selecting Fully Automated, you can still configure individual VM automation levels, so you can specify certain VMs to not be migrated at all (disabled) or to be set to Manual or Partially Automated. To configure individual VM automation levels, click on Virtual Machine Options, located under DRS. Usually, the default three-star level is a good starting point and works well for most environments. You should be careful when choosing more aggressive levels, as you could have VMs moving very frequently between hosts (i.e., VM pong), which can create performance issues because of the constant VMotions which cause an entire LUN to be locked during the operation (i.e., SCSI reservations).

• Question 115:

  When you add an ESXi 6.x host to a new Cluster, which vSphere object owns the CPU and Memory resources of the hosts?

  A. vCenter Server

  B. Datacenter

  C. Cluster

  D. Host

  Correct Answer: C

  Cluster owns the CPU and memory resources of the hosts when you add an ESXi 6.x host to a new cluster. Reference: https://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenterserver-60-resource-management-guide.pdf

• Question 116:

  A vApp template recently added to a Content Library is not displayed.

  Which two actions could correct this problem? (Choose two.)

  A. Manually synchronize the library

  B. Select the Download all library content immediately option

  C. Select the Sync subscribed library option

  D. Manually download the vApp template

  Correct Answer: AB

  If the vApp template is not displayed in the content library, select the download all library content immediately option and manually synchronize the library.

• Question 117:

  An administrator wants to deploy a vApp and dynamically assign IP addresses without a DHCP server on the network.

  Which action would you take to accomplish this task?

  A. Enable IP pools.

  B. Configure a local DHCP server in the vApp.

  C. Enable NAT on the vApp router.

  D. Configure the guest OS for workgroup and WINS.

  Correct Answer: A

  IP pools were first introduced with vSphere 4, but they're not necessarily used by everyone. IP pools are necessary if you want create or deploy a vApp. They provide a network identity to vApps. IP pool gives a network config to VMs that run in the vApp. So you'll also need to have an IP pool configured if you want to test vCloud Automation Center (VCAC) or Horizon Workspace.

  When you configure an IP Pool you specify a range of either IPv4 or IPv6 addresses, DNS and proxy settings, and select which vSwitch port groups that the pool will be available to. Usually you'll want to do a static IP for server VMs, but you might want to have a test VLAN for developments and you need DHCP there.

• Question 118:

  A vApp is running out of compute resources when overall activity is high within the resource pool. At other times, everything is fine.

  What should be done to resolve this issue?

  A. Increase the size of the resource pool Shares.

  B. Set the vApp's CPU and Memory Reservation Type to Expandable.

  C. Set the vApp's CPU and Memory Limit to Unlimited.

  D. Create a new resource pool with the existing hardware configuration.

  Correct Answer: B

  For the problem, set the vApp CPU and memory reservation type to expandable.

• Question 119:

  An administrator has a virtual machine that requires four times the compute resources than other virtual machines on the same ESXi 6.x host.

  How should the administrator configure the virtual machine settings, in order to be prepared for any resource contention?

  A. Set the shares of the priority virtual machine to High and the rest to Low.

  B. Set the shares of the priority virtual machine to High.

  C. Set the shares of the priority virtual machine to High and the rest to Normal.

  D. Set the shares of the priority virtual machine to Normal and the rest to Low.

  Correct Answer: A

  For the virtual machine that requires more resources, you can set the shares of the priority VM to high and

  set the rest to medium or low.

• Question 120:

  Which two options would allow a database administrator, with no access to the vSphere infrastructure, to connect to a virtual machine? (Choose two.)

  A. Use the Virtual Machine Remote Console (VMRC).

  B. Use Remote Desktop Protocol (RDP) to connect.

  C. Ask the administrator to grant permission to access the console through vCenter Server.

  D. Ask the administrator to grant permission to access with the Horizon View Direct Connect Client.

  Correct Answer: BC

  Accessing a virtual machine with no access to vSphere environment is tricky. You can use virtual machine

  remote console to remotely access the VM by asking the admin to grant permission to access the console

  through vcenter server.
