VMware 2V0-620 Online Questions & Answers

• Question 41:

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

  ---

  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 43:

  When attempting to access a virtual machine, an administrator is unable to login using the vSphere credentials. What two options are probable causes of the authentication failure? (Choose two.)

  A. The vSphere credentials have not been granted permissions.
  B. The vSphere credentials are granted read-only permissions.
  C. The vSphere credentials are granted no-access permissions.
  D. The vSphere credentials are not a member of the local administrator group.
  A. The vSphere credentials have not been granted permissions.
  B. The vSphere credentials are granted read-only permissions.

  ---

  While the details of authentication and authorization differ between ESX/ESXi and vCenter Server, the model itself is the same for both system. It relies on privileges, roles, and permissions.

• Question 44:

  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.
  A. Directly from the template.
  B. From a compute resource.

  ---

  You can deploy a virtual machine directly from the template. A compute resource can also be used for deploying a VM.

• Question 45:

  An administrator is migrating a virtual machine from a Test cluster to a Production cluster. The two environments do not have any shared storage. What is the easiest way to accomplish this task?

  A. Perform a Storage vMotion.
  B. Perform a regular vMotion.
  C. Perform a Virtual to Virtual migration.
  D. Perform a backup and restore using VMware Data Protection.
  B. Perform a regular vMotion.

• Question 46:

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

  ---

  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 47:

  Refer to the Exhibit.

  

  An administrator has been given requirements to configure vMotion for a new virtual machine. The configuration should: Provide Network Redundancy Use VLAN 550 Be secured against anyone trying to spoof communication

  The vSwitch1 configuration is shown in the Exhibit.

  Which three changes should be made to meet the stated requirements? (Choose three.)

  A. The VLAN ID must be set appropriately.
  B. The default values for MAC Address Changes and Forged Transmits must be altered.
  C. The teaming and failover adapters must be set appropriately.
  D. The Traffic Shaping configuration must be altered.
  E. The Load Balancing Policy must be set appropriately.
  A. The VLAN ID must be set appropriately.
  B. The default values for MAC Address Changes and Forged Transmits must be altered.
  C. The teaming and failover adapters must be set appropriately.

  ---

  First, VLAN ID must be set appropriately. Default values for Mac address changes and forged transmits must be altered and the teaming and failover adapters must be set accordingly.

• Question 48:

  An attempt to enable vSphere Fault Tolerance for a powered-on virtual machine fails. Which two scenarios would result in this failure? (Choose two.)

  A. The virtual machine has three vCPUs configured.
  B. The host on which the virtual machine is running has insufficient memory resources.
  C. The virtual machine has insufficient resources to accommodate full reservation plus the overhead memory.
  D. VMware High Availability is enabled on the cluster of which this host is a member.
  B. The host on which the virtual machine is running has insufficient memory resources.
  C. The virtual machine has insufficient resources to accommodate full reservation plus the overhead memory.

  ---

  vSphere Fault Tolerance automatically tries to allocate a full memory reservation on the host for the VM. Overhead memory is required for fault tolerant VMs and can sometimes expand to 1 to 2 GB. If the powered-on VM is running on a host that has insufficient memory resources to accommodate the full reservation plus the overhead memory, trying to turn on Fault Tolerance fails. Subsequently, the Unknown error message is returned.

• Question 49:

  Which two networking connection types can be configured on a virtual switch? (Choose two.)

  A. Virtual machine portgroups
  B. VMkernel services (such as NFS, iSCSI, or vMotion) to the physical network
  C. Web services over the Management Network
  D. NFS and FCoE storage services
  A. Virtual machine portgroups
  B. VMkernel services (such as NFS, iSCSI, or vMotion) to the physical network

  ---

  Virtual machine portgroups and Vmkernel services can be configured on a virtual switch. Reference: https://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

• Question 50:

  An administrator is virtualizing a physical application server and adding it to an existing multi-tiered vApp. The application license is currently tied to the physical NIC's MAC address, so the administrator needs to ensure the license will function properly in the virtual machine.

  Which two actions can the administrator take to satisfy this task? (Choose two.)

  A. Set the MAC address for the vNIC in the guest operating system.
  B. Install the physical server's NIC into the ESXi host.
  C. Configure the MAC address for the vNIC using the vSphere Web Client.
  D. Assign the physical server NIC's MAC address in the vSphere Distributed Switch.
  A. Set the MAC address for the vNIC in the guest operating system.
  B. Install the physical server's NIC into the ESXi host.

  ---

  First set the MAC address for the vNIC in the guest operating system and install the physical server's NIC into the ESXi host. Reference: http://rickardandersson.com/manual-mac-address-for-a-vmware-guest
