VMware 2V0-21.23 Online Questions & Answers

• Question 1:

  An administrator creates a virtual machine that contains the latest company-approved software, tools and security updates. Company policy requires that only full clones are allowed for server workloads.

  A combination of which two tasks should the administrator complete to prepare for the deployment of this virtual machine for multiple users? (Choose two.)

  A. Set appropriate permissions on the virtual machine.
  B. Create a virtual machine customization specification.
  C. Upgrade the virtual hardware.
  D. Convert the virtual machine to a template.
  E. Take a snapshot of the virtual machine.
  B. Create a virtual machine customization specification.
  D. Convert the virtual machine to a template.

  explanation:

  Explanation/Reference:

  Option B and D are correct because they allow the administrator to create a virtual machine customization specification, which can be used to customize guest operating system settings for multiple virtual machines, and convert the virtual machine to a template, which can be used to create full clones of server workloads. Option A is incorrect because assigning appropriate permissions on the virtual machine does not prepare it for deployment for multiple users. Option C is incorrect because upgrading the virtual hardware does not prepare it for deployment for multiple users. Option E is incorrect because taking a snapshot of the virtual machine does not prepare it for deployment for multiple users.

  Explanation/Reference:

  The minimum network throughput in Gb/s for vSAN using the Express Storage Architecture (ESA) is 1 Gb/s, which is the minimum requirement for vSAN network adapters. However, VMware recommends using 10 Gb/s or higher for better performance and reliability. References: https://docs.vmware.com/en/VMware- vSphere/8.0/com.vmware.vsphere.vsan-planning.doc/GUID-9F1D4A3B-3392-4684-812C- DB8042C1FBCD.html https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID- 1E39EF05-1DD7-4E9B-B9FE-6F373AA81862.html https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID- 1E39EF05-1DD7-4E9B-B9FE-6F373AA81862.html

• Question 3:

  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:

  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 4:

  A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently, this VMkernel port is configured for supporting live virtual machine (VM) migrations.

  Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?

  A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.
  B. Remove PROD01 and create a new VMkernel port with the TCP/IP stack set to provisioning.
  C. Create a new VMkernel port and set the TCP/IP stack to provisioning.
  D. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.
  A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.

  ---

  explanation:

  Explanation/Reference:

  Select a TCP/IP stack from the list. Once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later. If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host. All VMkernel adapters for vMotion on the default TCP/IP stack are disabled for future vMotion sessions. If you set the Provisioning TCP/IP stack, VMkernel adapters on the default TCP/IP stack are disabled for operations that include Provisioning traffic, such as virtual machine cold migration, cloning, and snapshot migration.

  F. Replace the solution user certificates with trusted certificates generated from the VMware Certificate Authority (VMCA).
  B. Replace the machine SSL certificates with custom certificates generated from the Enterprise CA.
  D. Replace the VMware Certificate Authority (VMCA) certificate with a custom certificate generated from the Enterprise CA.
  E. Replace the solution user certificates wife custom certificates generated from the Enterprise CA.

  ---

  explanation:

  Explanation/Reference:

  Option B, D and E are correct because they allow the administrator to replace the machine SSL certificates, the VMware Certificate Authority (VMCA) certificate and the solution user certificates with custom certificates generated

  from the Enterprise CA, which will ensure that all certificates are trusted by the Enterprise CA and minimize the ongoing management overhead of replacing certificates. Option A is incorrect because replacing the VMCA certificate with a self-

  signed certificate generated from the VMCA will not ensure that the certificate is trusted by the Enterprise CA. Option C is incorrect because replacing the machine SSL certificates with trusted certificates generated from the VMCA will not

  ensure that the certificates are trusted by the Enterprise CA. Option F is incorrect because replacing the solution user certificates with trusted certificates generated from the VMCA will not ensure that the certificates are trusted by the

  Enterprise CA.
