VMware 2V0-21.23 Online Questions & Answers

• Question 151:

  A vSphere environment is experiencing intermittent short bursts of CPU contention, causing brief production outages for some of the virtual machines (VMs). To understand the cause of the issue, the administrator wants to observe near real-time statistics for all VMs.

  Which two vSphere reporting tools could the administrator use? (Choose two.)

  A. Advanced Performance Charts
  B. esxcli
  C. resxtop
  D. Overview Performance Charts
  E. esxtop
  A. Advanced Performance Charts
  E. esxtop

  ---

  Explanation/Reference:

  Advanced Performance Charts and esxtop are both vSphere reporting tools that can be used to observe near real-time statistics for all VMs. Advanced Performance Charts provides a graphical view of performance data, while esxtop is a command-line tool that provides more detailed information.

• Question 152:

  An administrator has a host profile named Standard-Config. The administrator wants to change the other host profiles to use only the storage configuration settings that are defined in the Standard-Config host profile.

  What should the administrator do to make this change?

  A. Export host customizations and import them to the other host profiles.
  B. Copy the storage settings from Standard-Config to all other host profiles.
  C. Duplicate the Standard-Config host profile and only modify the storage configuration settings.
  D. Export the Standard-Config host profile and attach it to the other hosts.
  B. Copy the storage settings from Standard-Config to all other host profiles.

  ---

  Explanation/Reference:

  Option B is correct because it allows the administrator to copy the storage settings from Standard-Config host profile to all other host profiles without affecting other settings. Option A is incorrect because it only exports host customizations and not host profile settings. Option C is incorrect because it creates a new host profile instead of modifying the existing ones. Option D is incorrect because it attaches the Standard-Config host profile to the other hosts instead of changing their host profiles.

  A. The external Platform Services Controller needs to be converged into an embedded vCenter Server Appliance.
  B. The external Platform Services Controller needs to be decommissioned following the deployment of the new vCenter Server Appliance.
  C. The external Platform Services Controller backup can be restored to a new embedded vCenter Server Appliance.
  D. The external Platform Services Controller needs to be upgraded after the vCenter Server Appliance.
  E. The external Platform Services Controller needs to be powered down while a new vCenter Server Appliance is deployed.
  C. The external Platform Services Controller backup can be restored to a new embedded vCenter Server Appliance.
  E. The external Platform Services Controller needs to be powered down while a new vCenter Server Appliance is deployed.

• Question 155:

  Refer to the exhibit.

  

  An administrator repeatedly encounters this error message while attempting to connect to vCenter Server.

  What should the administrator do to address this error message? (Choose the best answer.)

  A. Use a different browser.
  B. Trust the VMware certificate authority (CA) root certificate.
  C. Restart the vCenter Server Appliance.
  D. Reissue a new, unexpired certificate.
  D. Reissue a new, unexpired certificate.

• Question 156:

  An administrator notices a Fibre Channel adapter in an ESXi host has been experiencing inconsistent connectivity states.

  Which trigger can be used to quickly identify the issue and alert the administrator so that the issue can be resolved?

  A. Host Connection Lost
  B. Lost Network Path Redundancy
  C. Lost Network Connectivity
  D. Lost Storage Connectivity
  D. Lost Storage Connectivity

  ---

  Explanation/Reference:

  https://kb.vmware.com/s/article/2014553 Book course: 6-23 Fibre Channel SAN Components Using SAN switches, you can set up path redundancy to address any path failures from host server to switch, or from storage array to switch. 6-25 Multipathing with Fibre Channel By default, ESXi hosts use only one path from a host to a given LUN at any one time. If the path actively being used by the ESXi host fails, the server selects another available path. The trigger that can be used to quickly identify the issue and alert the administrator so that the issue can be resolved is: Lost Storage Connectivity This alert is triggered when an ESXi host loses connectivity to storage devices. In this case, it would alert the administrator to the inconsistent connectivity states of the Fibre Channel adapter12.

• Question 157:

  An administrator is NOT able to enable ESXi secure boot.

  What is a possible cause of this issue? (Choose the best answer.)

  A. The vCenter Server version is 7.0.
  B. ESXi is using Trusted Platform Module version 1.2.
  C. The ESXi version is 7.0
  D. ESXi is using Unified Extensible Firmware Interface (UEFI).
  C. The ESXi version is 7.0

• Question 158:

  Which two statements are true regarding the use of firmware update packages in vSphere Lifecycle Manager? (Choose two.)

  A. A hardware support manager must be registered as a vCenter Server extension.
  B. The firmware and drivers add-on are distributed through the official VMware online depot.
  C. The firmware and drivers add-on can be used on clusters that are managed with baselines.
  D. The firmware and drivers add-on can add or remove components from the ESXi base image.
  E. The firmware and drivers add-on is provided by a third-party vendor.
  A. A hardware support manager must be registered as a vCenter Server extension.
  D. The firmware and drivers add-on can add or remove components from the ESXi base image.

• Question 159:

  An administrator receives an escalation to investigate a low disk space alarm on a datastore. The administrator discovers that a snapshot has been accidentally taken on a production, write-intensive database server. The snapshot has grown to nearly 1 TB in size in less than an hour and continues growing every second.

  Which behavior should the administrator expect while deleting the snapshot? (Choose the best answer.)

  A. ESXi will create a virtual RAM disk to cache ongoing database write activity; performance impact will be limited.
  B. ESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result in long stun times.
  C. ESXi will merge the snapshot delta disk into the base disk; the virtual machine will be briefly stunned.
  D. ESXi will instantly switch from the base disk to the snapshot delta disk with no performance impact.
  B. ESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result in long stun times.
