VMware 2V0-21.23 Online Questions & Answers

• Question 1:

  The vCenter inventory contains a virtual machine (VM) template called Linux-01. The administrator wants to install a software patch into Linux-01 while allowing users to continue to access Linux-01 to deploy VMs. Which series of steps should the administrator take to accomplish this task?

  A. 1. Verify that Linux-01 is in a content library 2. Clone Linux-01 3. Convert the clone to a VM 4. Install the software patch.
  B. 1. Convert Linux-01 to a VM 2 Install the software patch 3 Convert the VM back to a VM template 4 Add Linux-01 to the content library.
  C. 1. Verify that Linux-01 is in a content library 2. Checkout Linux-01 3. Install the software patch 4.Check in Linux-01
  D. 1. Clone Linux-01. 2. Convert the clone to a VM 3. Install the software patch. 4. Convert the VM back to a template.
  C. 1. Verify that Linux-01 is in a content library 2. Checkout Linux-01 3. Install the software patch 4.Check in Linux-01

  ---

  Explanation/Reference:

  The administrator should clone Linux-01, which creates a copy of the virtual machine template. The administrator should then convert the clone to a VM, which allows the administrator to power on and modify the virtual machine. The administrator should then install the software patch on the VM, which updates the application. The administrator should then convert the VM back to a template, which preserves the changes made to the VM and allows users to deploy VMs from it.

• Question 2:

  After adding a new vSphere ESXi host with identical hardware configuration to an existing vSphere cluster, which task would an administrator complete prior to checking the compliance with an existing host profile?

  A. Attach the host profile to the new host
  B. Duplicate the host profile
  C. Copy the host settings from the new host
  D. Import the host profile
  A. Attach the host profile to the new host

  ---

  Explanation/Reference:

  The task that should be completed prior to checking the compliance with an existing host profile is to attach the host profile to the new host, which allows applying the configuration template of the reference host to the new host.

• Question 3:

  An administrator is attempting to configure Storage I/O Control (SIOC) on five datastores within a vSphere environment. The administrator is being asked to determine why SIOC configuration completed successfully on only four of the datastores.

  What are two possible reasons why the configuration was not successful? (Choose two.)

  A. The datastore contains Raw Device Mappings (RDMs).
  B. SAS disks are used for the datastore.
  C. The datastore has multiple extents.
  D. The datastore is using ISCSI.
  E. The administrator is using NFS storage.
  A. The datastore contains Raw Device Mappings (RDMs).
  C. The datastore has multiple extents.

  ---

  Explanation/Reference:

  SIOC configuration may fail if the datastore contains RDMs or has multiple extents, as these are not supported by SIOC.

  References: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-FB3F5C5C-D3F6-4D6F-B1A2- C8C6A2D3A3F9.html

  Storage I/O Control is supported on Fibre Channel-connected, iSCSI-connected, and NFS- connected storage. Raw Device Mapping (RDM) is not supported. Storage I/O Control does not support datastores with multiple extents.

• Question 4:

  Exhibit switch

  

  An administrator configures a distributed switch and adds the first VMware ESXi server to it.

  The administrator also performs the following activities:

  The administrator assigns two uplinks to the distributed switch.

  The administrator enables uplink teaming.

  When attempting to perform a health check of the teaming policy, the health status of the Teaming and Failover reports as ' Unknown?, as seen in the exhibit.

  What can the administrator changes in the distributed switch for the health status to report correctly?

  A. Add a minimum of three hosts with two uplinks each
  B. Add a minimum of two hosts with two uplinks each
  C. Add a minimum of three hosts with four uplinks each
  D. Add a minimum of two hosts with one uplink each
  B. Add a minimum of two hosts with two uplinks each

• Question 5:

  Refer to the exhibit.

  

  After removing an ESXi host from a cluster for maintenance, a number of virtual machines have encountered the warning seen in the exhibit. After re-adding the ESXi, the issue is resolved. Which step should the administrator take to move the triggered alarm to its normal state?

  A. Ignore
  B. Reset to Green
  C. Acknowledge
  D. Disable
  B. Reset to Green

• Question 6:

  What are two functions of vSphere Lifecycle Manager? (Choose two.)

  A. Update ESXi hosts in a cluster using baselines
  B. Upgrade VMware Tools and virtual machine hardware
  C. Run vCenter Server interoperability reports
  D. Run vCenter Server upgrade pre-checks
  E. Update standalone ESXi hosts using images
  B. Upgrade VMware Tools and virtual machine hardware
  E. Update standalone ESXi hosts using images

• Question 7:

  An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA).

  What is the minimum supported network throughput in Gb/s for each host?

  A. 50
  B. 10
  C. 25
  D. 1
  B. 10

  ---

  Explanation/Reference:

  The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10. References: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan- planning.doc/GUID-FCEA0CDD-F40F-45EB-A27F-F24005BA0749.html

  vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

• Question 8:

  Which feature can an administrator configure to have a copy of critical virtual machines in another cluster? (Choose the best answer.)

  A. vSphere Storage vMotion
  B. vSphere Fault Tolerance
  C. vSphere Replication
  D. Instant Clone
  D. Instant Clone

• Question 9:

  An administrator needs to create affinity rules for the following vSphere cluster setup:

  The cluster contains two virtual machines (VMs) named app01 and app02.

  The cluster contains six hosts named esx11 through esx16.

  The app01 and app02 VMs run software that is licensed to run only on esx11, esx12, or esx13.

  vSphere Distributed Resource Scheduler (DRS) is configured

  Which set of steps must the administrator perform to ensure that the licensing requirements are met for app01 and app02?

  A. 1. Add all the hosts to a host group. 2. Create a VM-VM anti-affinity rule for app01 and app02
  B. 1. Add the esx11 - esx13 hosts to a host group 2. Create a VM-VM affinity rule for app01 and app02
  C. 1 Add the VMs to a VM group and the esx11 - esx13 hosts to a host group. 2 Create a VM-Host required rule between the VM group and the host group.
  D. 1. Add the VMs to a VM group and the esx11 - esx13 hosts to a host group. 2. Create a VM-Host preferential rule between the VM group and the host group
  C. 1 Add the VMs to a VM group and the esx11 - esx13 hosts to a host group. 2 Create a VM-Host required rule between the VM group and the host group.

  ---

  Explanation/Reference:

  Add the VMs to a VM group and the esx11 - esx13 hosts to a host group, which allows the administrator to group together virtual machines or hosts that share common characteristics or requirements. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-0591F865-91B5-4311-ABA6- 84FBA5AAFB59.html

• Question 10:

  If a distributed switch uses the "Route based on physical NIC load" load balancing algorithm, what does the mean send or receive utilization of an uplink need to exceed for the flow of traffic to move to the second uplink?

  A. 75 percent of the capacity over a 30 second period
  B. 60 percent of the capacity over a 30 second period
  C. 60 percent of the capacity over a 40 second period
  D. 75 percent of the capacity over a 40 second period
  A. 75 percent of the capacity over a 30 second period

  ---

  Explanation/Reference:

  The distributed switch calculates uplinks for virtual machines by taking their port ID and the number of uplinks in the NIC team. The distributed switch tests the uplinks every 30 seconds, and if their load exceeds 75 percent of usage, the port ID of the virtual machine with the highest I/O is moved to a different uplink. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-959E1CFE- 2AE4-4A67-B4D4-2D2E13765715.html
