Which background process of a database instance, using Automatic Storage Management (ASM),
connects as a foreground process into the ASM instance?

A.
ASMB

B.
PMON

C.
RBAL

D.
SMON

Explanation:
The ASMB process of a database instance, using ASM, connects as a foreground process into the
ASM instance. This ASMB process is responsible for the communication between the database
and the ASM instance. The process monitor (PMON) process does not connect as a foreground
process into the ASM instance. The PMON process cleans up failed user processes and frees up

all the resources used by the failed processes. The RBAL process does not connect as a
foreground process into the ASM instance. The RBAL process is new background process of an
ASM instance, and this process coordinates rebalancing activity for disk groups. The system
monitor (SMON) process does not connect as a foreground process into the ASM instance. The
SMON process performs instance recovery at database start up by using the online redo log files.
