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
Correct Answer: B
Explanation/Reference:
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.

Correct answer is : B prtconf works for both SPARC & x86

root@test-lab:~# prtdiag | grep -i memory
Memory size: 16384 Megabytes
