How to tell if Apache 2 is using prefork or worker MPM?

Answer:

If you are running in Red Hat Linux/ Fedora/ CentOS

# httpd -V
....
Architecture:   64-bit
Server MPM:     Prefork
  threaded:     no
    forked:     yes (variable process count)
...

If you are running in Debian/ Ubuntu, you can use apache2 -V, which get the same output as above.
