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)? 

Answer options:

A. uname –a
B. prtconf | grep –i memory
C. sysdef | grep –i memory
D. vmstat
E. prtdiag | grep –i memory

B

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.
