Exam 1z0-083 topic 1 question 107 discussion

Agree with ssseee - D is CORRECT. I launched installer and only OSOPER group is OPTIONAL.

A is correct https://docs.oracle.com/en/database/oracle/oracle-database/19/ssdbi/creating-operating-system-privileges-groups.html#GUID-164A7218-166D-4B58-9A86-88149E8FCB83

For an Oracle Database installation on a Linux or UNIX operating system, the operating system group that is NOT required is the asmdba group. Here’s a breakdown of the groups and their usual purposes in Oracle installations: dba: Required for database administrators to manage the Oracle Database instance. oper: Optional, often used to grant specific users limited access to database management tasks (e.g., shutting down and starting the database). backupdba: Optional, used for backup and recovery operations. dgdba: Optional, used for managing Data Guard. kmdba: Optional, used for managing Oracle Key Vault. asmdba: Required only if Oracle Automatic Storage Management (ASM) is used. If you aren’t using ASM, you don’t need to create the asmdba group.

A: There is a quiz in the official "Oracle Database: Deploy, Patch and Upgrade Workshop, Student Guide D105893GC10 / D106067", p.109/292: QUIZ Which one of the following groups is not required for Oracle Database installation? a. OSASM b. OSOPER c. OSDBA --- Answer: a

D is optional , yeah

The database software owner must also have the OSDBA group and (if you create them) the OSOPER, OSBACKUPDBA, OSDGDBA, OSRACDBA, and OSKMDBA groups as secondary groups.

A is correct. Here is result from Oracle DB 19c Fresh install. cat /etc/group | grep -i oracle oinstall:x:54321:oracle dba:x:54322:oracle oper:x:54323:oracle backupdba:x:54324:oracle dgdba:x:54325:oracle kmdba:x:54326:oracle racdba:x:54330:oracle

A system privileges group whose members are granted administrative system privileges, including OSDBA, OSASM, and other system privileges groups. Oracle Database has two standard administration groups: OSDBA, which is required, and OSOPER, which is optional. OSOPER grants the OPERATOR privilege to start up and shut down the database (the SYSOPER privilege). By default, members of the OSDBA group have all privileges granted by the SYSOPER privilege. Choose the best answer？lost on this question.

The OSOPER group is used for operating system operations and is not required for Oracle Database installation.

D (OSOPER) is the only optional. note for oracle 19c grid installation A is a must. else your installation will not have access to the disk group. see below document https://docs.oracle.com/en/database/oracle/oracle-database/19/cwsol/creating-osasm-group.html#GUID-B13FBFB6-0714-4696-B52D-6DAEFF54AC38

Bad question, but I thin OSOPER is optional. OSASM is created as asmadmin

A - see RinD

A is correct --> "The database software owner must also have the OSDBA group and (if you create them) the OSOPER, OSBACKUPDBA, OSDGDBA, OSRACDBA, and OSKMDBA groups as secondary groups."

A is correct - Pay attention to the word OSASM - there is nothing by this name or word . Its either OSDBA for ASM which is asmdba or OSOPER for ASM - which is asmoper

A is correct

I think A is correct because in fact we do not need to create OSOPER as well as OSRACDBA and OSKMDBA and all privileges assigns to OSDBA, right? The question is badly formed

A is correct. OSASM must use when installing Grid https://docs.oracle.com/en/database/oracle/oracle-database/19/cwsol/creating-osasm-group.html
