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.
