VMware 2V0-51.23 Exam With Confidence Using Practice Dumps

A Trusted Platform Module (vTPM) is a virtualized version of a physical TPM device that provides enhanced security for virtual machines. A vTPM device can be added to a virtual machine to enable features such as encryption, attestation, and key management. A vTPM device requires a Key Management Server (KMS) to store and manage the encryption keys.

To create instant clones VMs with a vTPM device, the vCenter Server user must have certain privileges in addition to those required for instant clones without a vTPM device. One of these privileges is Manage KMS, which allows the user to perform cryptographic operations on the vTPM device, such as cloning, decrypting, encrypting, migrating, and registering. The Manage KMS privilege is part of the Cryptographic operations privilege group on vCenter Server.

The other options are not required only for instant clones VMs with a vTPM device:

• Upgrade virtual machine compatibility: This privilege allows the user to upgrade the virtual hardware version of a virtual machine to support new features and capabilities. This privilege is required for instant clones VMs regardless of whether they have a vTPM device or not.
• Configure Host USB device: This privilege allows the user to configure USB devices on an ESXi host and attach them to a virtual machine. This privilege is not related to vTPM devices or instant clones VMs.
• Manage custom attributes: This privilege allows the user to create, edit, and delete custom attributes for vCenter Server objects. Custom attributes are user-defined fields that can store additional information about objects. This privilege is not related to vTPM devices or instant clones VMs.

On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent. The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12.

The other options are not correct for this scenario:

• Administrator provides this information in the “Add Pool” creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the “Add Pool” creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine. The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3.
• Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment. DNS SRV records are optional and can be configured by the administrator to simplify client connections4.
• Administrator provides this information in the Horizon Agent Installation Wizard on the master image. This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on. The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5.

Cloud Pod Architecture is a feature that allows administrators to link multiple Horizon pods across sites and data centers to form a single logical entity called a pod federation. Cloud Pod Architecture enables global entitlements, which allow users to access desktops and applications from any pod in the pod federation. Cloud Pod Architecture also provides load balancing, high availability, and disaster recovery capabilities for Horizon deployments.

However, Cloud Pod Architecture has some feature limitations that administrators should be aware of. Two of these limitations are:

• Cloud Pod Architecture does not support Active Directory two-way trusts between domains: This means that the domains that contain the Horizon pods in the pod federation must have a one-way trust relationship, where the domain that contains the Cloud Pod Architecture home site trusts all the other domains, but not vice versa. A two-way trust relationship, where each domain trusts and is trusted by all the other domains, is not supported by Cloud Pod Architecture and can cause authentication and entitlement issues.
• Kiosk mode clients are not supported unless a workaround has been implemented: This means that users who log in to Horizon Client in kiosk mode, which is a mode that allows users to access a single desktop or application without entering credentials, cannot access desktops or applications from a Cloud Pod Architecture implementation. Kiosk mode clients are not compatible with global entitlements and load balancing features of Cloud Pod Architecture. However, there is a workaround that involves creating a dedicated user account and a dedicated desktop pool for each kiosk mode client and using a script to launch Horizon Client with the appropriate parameters. For instructions, see VMware Knowledge Base (KB) article 21488881.

The other options are not limitations of Cloud Pod Architecture:

• Cloud Pod Architecture is supported with Unified Access Gateway appliances: Unified Access Gateway is a platform that provides secure edge services for Horizon deployments, such as secure remote access, load balancing, and authentication. Unified Access Gateway is compatible with Cloud Pod Architecture and can be configured to route user requests to the appropriate pod in the pod federation based on global entitlements and load balancing policies.
• Cloud Pod Architecture can span multiple sites and data centers simultaneously: This is one of the main benefits of Cloud Pod Architecture, as it allows administrators to scale up and out their Horizon deployments across different geographic locations and network boundaries. Cloud Pod Architecture can support up to 15 pods per pod federation and up to 5 sites per pod federation, with a maximum of 200,000 sessions per pod federation.
• The Cloud Pod Architecture feature is supported in an IPv6 environment: IPv6 is the latest version of the Internet Protocol that provides a larger address space and enhanced security features for network communication. Cloud Pod Architecture supports IPv6 environments and can operate in mixed IPv4 and IPv6 environments as well.
