A container database, CDB1, contains a pluggable database PDB1.
Another container database is called CDB2.
You want to relocate PDB1 from CDB1 to CDB2 with near-zero down time.
Which three are required? (Choose three.)

To relocate a pluggable database (PDB) with near-zero downtime, certain conditions must be met. First, both the source container database (CDB1) and the target container database (CDB2) need to be in local UNDO mode to ensure proper management of undo data across shared environments. Additionally, both CDB1 and CDB2 must be in archivelog mode to ensure that all necessary transactions are logged and can be recovered in case of any issues during the relocation process. Therefore, options A, B, and E are required to successfully relocate PDB1 with near-zero downtime.
abe in my opinion
https://oracle-base.com/articles/12c/multitenant-relocate-pdb-12cr2 source and target CDBs need to have local undo mode so C,D,F is false Agree with A,B,E
Target CDB in Shared Mode: The target CDB doesn't need to be in Local Undo mode. In that case the new PDB being relocated will be converted to "Shared Undo". But you could have an issue here, if your source PDB is receiving several DMLs you could have some issues when you try to open the new PDB in read-write you will get a message saying "unrecovered txns found". In that case you must clear those unrecovered transactions by yourself and then re-execute "alter pluggable database open".
just because the others are surely wrong
A,B,E correct
