Which command would you use from the bash shell to determine the total amount of physical
memory installed in your Solaris system (x86 and SPARC)?

A.
uname –a

B.
prtconf | grep –i memory

C.
sysdef | grep –i memory

D.
vmstat

E.
prtdiag | grep –i memory

Explanation:
The prtconf command prints the system configuration information. The output includes the total amount of memory, and
the configuration of system peripherals formatted as a device tree.
If a device path is specified on the command line for those command options that can take a

device path, prtconf will only display information for that device node.
Reference: man prtconf
