An administrator creates a tag for a virtual machine (VM) in VMware Cloud Foundation (VCF)...

In VMware Cloud Foundation 9.0 Operations,tags created inside VCF Operations do not automatically appear in vCenter. Tags must be explicitly synchronized ("pushed") to the selected vCenter instance before they become usable for VM tagging within vCenter. This is because VCF Operations maintains its own metadata store for tags, super metrics, groups, and policies.

The correct workflow is:

Create the tag in VCF Operations.

Push (synchronize) the tag to the appropriate vCenter instance.

The tag then appears in vCenter’sTags & Custom Attributessection.

Administrators can then assign the tag to VMs.

If the push step is skipped, the tag exists only inside VCF Operations and cannot be referenced by vCenter, which is exactly the symptom described:tag not found when attempting to assign it to a VM.

Option A is incorrect because Custom Groups do not affect vCenter tag visibility.

Option B is incorrect because tag synchronization is not tied to a specific vCenter version as long as the vCenter is officially supported by VCF 9.x.

Option D is irrelevant—VMware Tools has nothing to do with tag visibility.
