Which statement is true about the outcome of this command?

Examine the output of the asmcmd and srvct1 commands:

$ asmcmd showclustermode
ASM cluster : Flex mode enabled

$ srvctl status asm -detail
ASM is running on host01,host02,host03

ASM home: /u01/app/12.1.0/grid
Password file: +DATA/orapwASM
