Firstly of all, it's not XPN testing, but testing the new options under gcp.platform. The issue is, the expected "*.apps.<cluster name>.<base domain>" record-set is not created in the specified public DNS zone.

Always

1. create install-config
2. edit the install-config.yaml, to insert valid publicDNSZone and privateDNSZone settings
3. create cluster
4. check the DNS record-sets in the public zone and the private zone 

There's no "*.apps.<cluster name>.<base domain>" record-set in the public DNS zone.

There should be the "*.apps.<cluster name>.<base domain>" record-set in the public DNS zone.

1. the DNS record-sets created in the public zone and the private zone respectively:
