How to Automate Unique Naming and Domain Joining for New Windows VMs in vSphere
Question
A vSphere administrator wants to ensure standardization of any new deployments of Widows VMs.
In order to accomplish this, the administrator creates a new Windows VM with all of the required settings.
What vSphere feature can the administrator leverage to ensure that each new Windows VM receives a unique name and is automatically joined to the domain after creation?

https://pubs.vmware.com/vsphere-4-esx-vcenter/index.jsp?topic=/com.vmware.vsphere.vmadmin.doc_41/vsp_vm_guide/The vSphere administrator can leverage the "Guest Operating System Customization" feature to ensure that each new Windows VM receives a unique name and is automatically joined to the domain after creation.
Guest Operating System Customization is a feature in vSphere that automates the process of customizing a guest operating system during deployment. It enables administrators to create a template or a master virtual machine with a pre-configured operating system and applications, and then deploy multiple virtual machines from that template or master with the same configuration.
To use this feature, the administrator can create a Windows VM with all the required settings, including the operating system, applications, and domain membership. Then, the administrator can run the Guest OS Customization Wizard to specify the customization options, such as the unique name, network settings, domain membership, and so on.
During the deployment of a new virtual machine from the template or master, the Guest OS Customization feature applies the customization settings to the new virtual machine, including assigning a unique name and joining it to the domain automatically.
Therefore, by using the Guest Operating System Customization feature, the vSphere administrator can ensure standardization of any new deployments of Windows VMs while also ensuring that each new Windows VM receives a unique name and is automatically joined to the domain after creation.
Option B (vRealize Orchestrator) is a workflow automation tool that can be used to automate complex tasks or processes in vSphere environments. However, it is not specifically designed for guest operating system customization.
Option C (Host Profiles) is a feature in vSphere that enables administrators to create a profile or a blueprint of an ESXi host's configuration and apply it to other hosts to ensure consistent configuration. While it can help ensure standardization of ESXi host configurations, it is not designed for guest operating system customization.
Option D (Sysprep) is a Microsoft tool that prepares a Windows operating system for cloning or imaging by removing unique system information, such as the computer name, security identifier (SID), and other settings that are specific to the source computer. While it can be used for guest operating system customization, it is not a vSphere feature, and it requires additional configuration and scripting to automate the process of joining a new VM to the domain.
