You are administering a multitenant container database (CDB) that has no startup triggers and contains three pluggable databases (PDBs)
You execute the command to start up the CDB:
SQL> STARTUP
Which statement is true?
A.
CDB$ROOT, PDB$SEED, and the PDBs are opened in read-only mode.
B.
CDB$ROOT and PDB$SEED are opened in read-only mode, but the PDBs are in closed mode.
C.
CDB$ROOT is opened in read/write mode, but PDB$SEED and the PDBs are in closed mode.
D.
CDB$ROOT is opened in read/write, PDB$SEED in read-only mode, and the PDBs in MOUNT state.
E.
CDB$ROOT, PDB$SEED, and the PDBs are opened in read/write mode.
D
To start up a CDB instance, the current user must have sufficient privileges and must bea common user whose current container is the root. When you open a CDB, its PDBs are by default mounted but not opened, but this can be changed with a trigger.
