VMware VMware Certifications 2V0-51.23 Questions & Answers

• Question 11:

  A VMware Horizon on-premises environment's Senior Administrator's team is attempting to update the golden image for an Instant Clone desktop pool which an administrator created a month before. The Senior Administrator's team is a

  member of the AD group "Horizon View Operators".

  The team states that they cannot login to the vCenter Server where the golden image resides to update the golden image.

  What must the Senior Administrator do to enable the team to connect to vCenter and update the VM that is the source of desktop pools for their on-premises VMware Horizon solution?

  A. Go to vSphere Client, add permissions for "Horizon View Operators".

  B. Connect to each desktop pool in Horizon, and add entitlements for "Horizon View Operators".

  C. Go to DEM (Dynamic Environment Manager) and add permissions for "Horizon View Operators" to update the golden image.

  D. Go to Horizon Console, add permissions for "Horizon View Operators".

  Correct Answer: A

  To enable the Senior Administrator's team, which is part of the "Horizon View Operators" AD group, to connect to vCenter and update the golden image, the Senior Administrator needs to assign the appropriate permissions in the vSphere Client. By adding the group to the vCenter Server with the necessary roles and privileges, members of the "Horizon View Operators" group will be able to access and modify the VMs required for maintaining the desktop pools in the VMware Horizon environment.

• Question 12:

  Which are the required permissions an administrator must assign to the user account for instant-clone operations in Active Directory before creating instant-clone desktop pools? (Choose three.)

  A. Create and Delete Child objects

  B. Read and Write All Properties

  C. Modify Owner

  D. Write to service principal names

  E. List contents

  F. Create and Delete Computer Objects

  Correct Answer: ABF

  For instant-clone operations in Active Directory, the user account used by VMware Horizon needs specific permissions to manage computer objects effectively. These include the ability to create and delete child objects and computer objects, as well as read and write all properties of those objects. These permissions ensure that Horizon can create, modify, and clean up computer accounts associated with instant clones, facilitating seamless desktop provisioning and management.

• Question 13:

  An administrator configured a virtual machine to use an NVIDIA card but the virtual machine is not starting up. What could be the cause of the issue? (Choose two.)

  A. 3D graphics cannot be used with local storage.

  B. The Desktop Pool doesn't support 3D cards.

  C. No suitable host could be found.

  D. Not all memory has been reserved on the VM.

  E. Not all CPU has been reserved on the VM.

  Correct Answer: CD

  When configuring a virtual machine to use an NVIDIA graphics card, issues such as the VM not starting can occur if there is no suitable host available that meets the requirements for 3D graphics, or if not all memory required by the 3D graphics card has been reserved for the VM. Ensuring that the host has the necessary 3D graphics capabilities and that the VM is configured with reserved memory can resolve these issues.

• Question 14:

  A Horizon administrator does not see the health status for the Unified Access Gateways (UAG) they configured in the Horizon Console. What two options could be causing the issue? (Choose two.)

  A. The Connection Server needs to be rebooted.

  B. The firewall hasn't been configured properly to allow traffic on port 443.

  C. Another license is needed for UAG health overview.

  D. The pod needs to be added to the Cloud Pod Federation.

  E. The name entered in the Horizon console doesn't match up with the system name in UAG.

  Correct Answer: BE

  If the Horizon Console does not display the health status of configured Unified Access Gateways (UAGs), it could be due to improper firewall configuration blocking traffic on port 443, which is essential for secure communication. Additionally, a discrepancy between the system name in UAG and the name entered in the Horizon Console can also prevent the console from correctly retrieving and displaying the UAG's health status.

• Question 15:

  An administrator needs to upgrade a Unified Access Gateway (UAG) appliance. The UAG is connected to a load balancer with other UAGs and has existing sessions. Which option provided allows minimal downtime for maintenance?

  A. Enable Quiesce Mode in the UAG Admin UI.

  B. Remove the Horizon Connection Server thumbprint in the UAG Admin UI.

  C. Suspend the UAG appliance.

  D. Power off the UAG appliance.

  Correct Answer: A

  Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

• Question 16:

  A senior Horizon administrator is tasked with enabling two-factor authentication for other Horizon administrators to login to the Horizon Console. Which option will the administrator use that supports two-factor authentication?

  A. Smart Card Authentication

  B. RSA SecureID

  C. SAML

  D. RADIUS

  Correct Answer: D

  RADIUS (Remote Authentication Dial-In User Service) supports two-factor authentication and can be integrated with VMware Horizon to secure administrative access to the Horizon Console. RADIUS servers authenticate users based on a combination of something they know (a password) and something they have (a token or mobile app-generated code), providing an added layer of security for administrative logins.

• Question 17:

  After a disaster recovery failure which left the data center unavailable, a company's VMware Horizon Administration Team has decided to increase the capacity of their VMware Horizon desktop pools and their resiliency. Which two deployment options would support the requirement? (Choose two.)

  A. VMware Horizon deployed in the same local data center.

  B. VMware Horizon Desktop deployed as a Service on vCloud Air.

  C. VMware Horizon deployed on VMware Cloud on VMware.

  D. VMware Horizon deployed on VMware Cloud on AWS.

  E. VMware Horizon deployed in a remote data center.

  Correct Answer: DE

  To increase the capacity and resiliency of VMware Horizon desktop pools, deploying Horizon on VMware Cloud on AWS or in a remote data center are viable options. VMware Cloud on AWS provides a scalable and secure cloud platform, allowing for quick expansion and disaster recovery capabilities. Similarly, deploying Horizon in a remote data center can provide geographical diversity, reducing the impact of localized disasters and improving overall resilience.

• Question 18:

  A VMware Horizon administrator is tasked with deployment of a desktop pool, which should fulfill these requirements:

  1.

  End-users should always get the same desktop VM.

  2.

  Backups with the existing VMware image-based backup tool should be supported.

  3.

  Desktop VMs will be cloned on a weekly basis per vSphere API. Which desktop solution can accomplish this requirement?

  A. Automated Desktop Pool, based on Dedicated Full Clone Virtual Machines.

  B. Automated Desktop Pool, based on Floating Full Clone Virtual Machines.

  C. Automated Desktop Pool, based on floating Instant Clones.

  D. Automated Desktop Pool, based on dedicated Instant Clones.

  Correct Answer: A

  An Automated Desktop Pool using Dedicated Full Clone Virtual Machines best meets the requirements because it ensures end-users always receive the same desktop VM, supports backups with VMware's image-based backup tools, and allows for cloning via the vSphere API on a weekly basis. Full clones are standalone VMs that don't depend on a parent VM after being created, making them suitable for image-based backups and consistent user experience.

• Question 19:

  Which two steps must be completed in order to expand a Writable Volume? (Choose two.)

  A. Select Volumes > Writables > Select Volume > Update Writable.

  B. Specify a size which is at least 1MB larger than the current size of the volume.

  C. Select Volumes > Writables > Select Volume > Expand.

  D. Specify a size which is at least 1GB larger than the current size of the volume.

  E. Modify the snapvol.cfg to reflect the new size.

  Correct Answer: AD

  To expand a Writable Volume in VMware Horizon, the administrator needs to navigate to the Volumes > Writables section in the Horizon Console, select the specific volume, and choose the option to update or expand the writable volume. The new size specified must be at least 1GB larger than the current size to ensure there is enough space for the expansion process and to accommodate the growth of user data.

• Question 20:

  Which two of the following are predefined Roles in Horizon Console? (Choose two.)

  A. Inventory Administrators

  B. Instant Clone Administrators

  C. Desktop Pool Administrators

  D. Server Administrators

  E. Local Administrators

  Correct Answer: AC

  In VMware Horizon, predefined roles such as Inventory Administrators and Desktop Pool Administrators are designed to provide granular access control within the Horizon Console. Inventory Administrators typically have permissions related to managing the overall inventory of virtual desktops and applications, whereas Desktop Pool Administrators are specifically focused on managing and configuring desktop pools, including their settings, assignments, and provisioning.
