S1000-007 Exam Dumps - IBM AIX v7 Administrator Specialty Questions and Answers

To prevent the telnet daemon from running and restarting after a reboot, the administrator should comment out the line related to telnet in the/etc/inetd.conffile by inserting a#at the beginning of the line. After making this change, running therefresh -s inetdcommand will apply the changes to theinetdservice without requiring a system reboot. This effectively disables the telnet service.References:= IBM AIX Documentation

When using the connect=shell option, a successful NIM operation requires that the root user on the NIM client has an entry in its .rhosts file for the NIM master, and that the file permissions are set to 600. This is documented in the IBM AIX v7 Administrator Specialty Study Guide. More information on this can be found at https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/com.ibm.aix.security/nim_security.htm.

The administrator has failed to run the cfgmgr command before rebooting the systems. Running the cfgmgr command before rebooting a system is important, as it ensures that any changes made to the configuration are written to the system, otherwise the changes may be lost when the system is rebooted. Other commands such as chdev and route add are not related to this issue and will not solve the problem.

For more information on the cfgmgr command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 10-7. The guide can be found here:https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/cfgmgmt/cfgmgr_command.htm.

The two additional commands that an AIX V7.2 administrator should run after mirroring the rootvg with the mirrorvg command are 'bosboot' and 'bootlist'. The bosboot command is used to update the boot image on all disks in the volume group, and the bootlist command is used to set the boot order for the system. These commands are available on IBM AIX v7 systems and are documented in the IBM AIX v7 Administrator Specialty Study Guide. For more information, please see the IBM documentation at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/bosboot.htm  and https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/bootlist.htm.

Devices that are connected to the system can be in one of four states.

Devices that are connected to the system can be in one of the following states:

Item

Description

Undefined

The device is unknown to the system.

Defined

Specific information about the device is recorded in the customized database, but it is unavailable to the system.

Available

A defined device is coupled to the operating system, or the defined device is configured.

Stopped

The device is unavailable but remains known by its device driver.

If a tty device and a printer alternately use the same tty connector, both a tty device and a printer are defined on the same parent and port in the device configuration database. Only one of these devices can be configured at a time. When the tty connector is configured, the printer specific setup information is retained until it isconfigured again. The device is not removed; it is in the defined state. Maintaining a device in defined state retains customized information for a device that is not currently in use, either before it is first made available or while it is temporarily removed from the system.

If a device driver exists for a device, the device can be made available through the device driver.

In AIX, when creating a new user account without specifying a group, the default group assigned isstaff. This is a predefined group in AIX systems that is typically used for regular user accounts. It provides basic permissions and access suitable for non-administrative users.References: IBM AIX Documentation - User Management

Thecrusuer sugroups=system rootcommand limits root user access to only members of the group calledsystem. This command sets the secondary groups (sugroups) for the root user to include only thesystemgroup, thereby restricting root access to users within that group.References:= IBM AIX Security Documentation
