Which three statements are true concerning the multitenant architecture?
A.
Each pluggable database (PDB) has its own set of background processes.
B.
A PDB can have a private temp tablespace.
C.
PDBs can share the sysaux tablespace.
D.
Log switches occur only at the multitenant container database (CDB) level.
E.
Different PDBs can have different default block sizes.
F.
PDBs share a common system tablespace.
G.
Instance recovery is always performed at the CDB level.
Explanation:
B: A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces.It can also
contains other user created tablespaces in it.*
Incorrect:
Not A: High consolidation density. The many pluggable databases in a single
container database share its memory and background processes, letting you operate
many more pluggable databases on a particular platform than you can single databases
that use the old architecture.
Not C, Not F: Oracle Database creates both the SYSTEM and SYSAUX tablespaces as part of
every database.
Correct option is – BDG. E is not correct.
Log switch occurs only at CDB level.
BDG
BDG
BDG
BDG should be correct answer .
Log switches occur only at the multitenant container database (CDB) level. –> that is 100% correct
Different PDBs can have different default block sizes. –> that is 200% wrong
BDG
