Which two are true about accounts, groups, and roles in the Solaris user database?
A.
All Solaris user accounts must have a unique UID number.
B.
A Solaris account name may be any alphanumeric string, and can have a maximum length of 8
characters.
C.
Account UID numbers 0-09 are system-reserved.
D.
The GID for an account determines the default group ownership of new files created by that
account.
E.
The groups that an account is a member of are determined by the entries in the /etc/group file.
Explanation:
A: Solaris uses a UID (User ID) to identify each user account. The UID is a unique
number assigned to each user. It is usually assigned by the operating system when the account is
created.
B: In Solaris the account name can include any alphanumeric string (and . _ -). The maximum
length is 8 characters.

A and B
I don’t think “A” is correct, check the “-o” option in useradd. Answer B + D ??
Hi Paul, A is correct. Users cannot have the same UID, you can try it yourself even, it will give you an ERROR: uid is already in use. Choose another.
Honestly, I can’t really see a wrong answer here.
Except for C, unless that was a typo error, and should be 0-99
A,B
D and E
useradd command accepts usernames up to 32 characters. OS may warn beyond 8 characters – simply ignore if more than 8 characters is a requirement.
eg.,
# useradd guyfawkes
UX: useradd: guyfawkes name too long.
# su guyfawkes
# id guyfawkes
uid=110(guyfawkes) gid=10(staff)
A & D
B incorrect with test
#useradd test123456789
UX: useradd: test123456789 name too long.
# cat /etc/passwd | grep test
test123456789:x:1002:1::xxxxx:/usr/bin/bash
A, D & E are correct
sorry A is incorrect with test:
useradd -u 101 -o test2 (uid 101 exist with user test1) and the command pass
so the correct answer are D, E
