Which two statements are true regarding the default service that is automatically created upon PDB creation in a RAC database environment? (Choose two.)
The two correct statements regarding the default service that is automatically created upon PDB creation in a RAC database environment are: it cannot be used to automate the opening of the PDB by the Clusterware, and it is not automatically registered in the OCR. The default service does not facilitate the PDB opening automation by Clusterware, hence option B is correct. Additionally, the default service requires manual registration in the Oracle Cluster Registry (OCR), thus making option E also correct.
Looks like B,E https://docs.oracle.com/en/database/oracle/oracle-database/23/multi/administering-pdbs-with-sql-plus.html#GUID-5A2471BC-8501-4E38-BD28-7EE182F3B3A7
A, B or B, E? I think A is wrong - in general I will say "It is uniformly available on all instances" for admin and policy managed databases B - is correct for sure E - default service is not registered - I vote E
