S1000-007 Exam Dumps : IBM AIX v7 Administrator Specialty

The account name "adm" is a standard account that comes pre-installed with AIX. It is used for system administration tasks and has specific roles and permissions associated with it. Attempting to create a new account with the same name would conflict with the existing standard account, hence it cannot be used for creating a new user account.References:= IBM AIX Documentation

The root account is the special user in the /etc/passwd file with the user ID (UID) of 0 and is commonly given the user name, root. It is not the user name that makes the root account so special, but the UID value of 0. This means that any user that has a UID of 0 also has the same privileges as the root user. Also, the root account is always authenticated by means of the local security files.

Themount -acommand in AIX mounts all file systems that are specified in the/etc/filesystemsfile and have the attributemount=true. This ensures that only those file systems that are configured to be automatically mounted are actually mounted when this command is executed. It does not mount all defined file systems, only those marked for automatic mounting.References: IBM AIX Documentation – mount
