Which three statements are true about administering user accounts and groups for an Oracle
Linux server in preparation for installing the Oracle Database server?
A.
The Oracle software owner must be a Linux user called oracle.
B.
The Oracle software owner must not be the root user.
C.
The owner of the Oracle httpd daemon process must be the Linux user called nobody.
D.
A Linux user who is a member of the OSDBA group may start an Oracle database instance.
E.
The /etc/sudoers file must specify that the Oracle software owner be allowed to run commands
as root.
F.
The OINSTALL group owns the Oracle Inventory.
Explanation:
A: The Oracle software owner user (typically, oracle)
You must create this user the first time you install Oracle software on the system. This user owns
all of the software installed during the installation. This user must have the Oracle Inventory group
as its primary group. It must also have the OSDBA and OSOPER groups as secondary groups.
D: The OSDBA group (dba)
You must create this group the first time you install Oracle Database software on the system. It
identifies operating system user accounts that have database administrative privileges (theSYSDBA privilege). The default name for this group is dba.
F: The Oracle Inventory Group (typically, oinstall)
You must create this group the first time you install Oracle software on the system. The default
name chosen for this group is oinstall. This group owns the Oracle inventory that is a catalog of all
Oracle software installed on the system.
A is wrong, Oracle software owner user may be called different than oracle
B is right. root can not be software owner
B,D,F
The answer is A,D,F
===================
A) Right
The Oracle software owner user (oracle)
You must create this user the first time you install Oracle software on the system. This user owns all of the software installed during the installation. The usual name chosen for this user is oracle. This user must have the Oracle Inventory group as its primary group.

Answer : A, B and D
ORAINVENTORY and OSDBA are not real names of operating system groups. They are some sort of logical notion of groups (meta groups?).
The oracle software account, usually called “oracle”, owns Oracle software and should be part of the ORAINVENTORY group (called “oinstall”), for the common inventory. OSDBA group(called “dba”) is for granting SYSDBA privilege/s to os user, via os authentication.
Not F, because ORAINVENTORY owns the Oracle Inventory represented in OS in Oracle documentation by group name “oinstall”.
B,D,F
F: You must create this group the first time you install Oracle software on the system. The default name chosen for this group is oinstall. This group owns the Oracle inventory that is a catalog of all Oracle software installed on the system.

Not A: The Oracle Software Owner User (typically, oracle). So not must be oracle… You can use user for that.
* you can use another user for that.
B D F
Correct will be
B, D, F,

The Oracle Software Owner User (typically, oracle)
You must create this user the first time you install Oracle software on the system. This user owns all of the software installed during the installation. This user must have the Oracle Inventory group as its primary group.
Note:
In Oracle documentation, this user is referred to as the oracle user.
A single Oracle Inventory group is required for all installations of Oracle software on the system. After the first installation of Oracle software, you must use the same Oracle Inventory group for all subsequent Oracle software installations on that system. However, you can choose to create different Oracle software owner users, OSDBA groups, and OSOPER groups (other than oracle, dba, and oper) for separate installations. By using different groups for different installations, members of these different groups have DBA privileges only on the associated databases rather than on all databases on the system.
The option A, indicate “software owner must be a Linux user called oracle.”, and this it’s optional
