NEW QUESTION # 23
Which user account is always UID 0 on AIX?
- A. system
- B. root
- C. bin
- D. admin
Answer: B
Explanation:
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.

NEW QUESTION # 24
A system administrator includes the values RES TIMEOUT=1 and RES_RETRY=1 in the /etc/environment file. What is the effect of this change?
- A. It reduces the failover time to the secondary NTP Server when the first NTP Server is unavailable.
- B. It reduces the failover time to the secondary name server when the first name server is not reachable.
- C. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
- D. It causes ssh connections to disconnect after 1 minute of no activity.
Answer: D
Explanation:
The RESTIMEOUT and RESRETRY parameters in the /etc/environment file control how long the system will wait for a response from the DNS server when making name resolution requests. By setting these values to 1, the system will wait no longer than 1 second for a response, which will result in ssh connections disconnecting after 1 minute of inactivity. 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/ssh_config_timeout.htm.

Answer: C
Explanation:
"The command to limit root user access to only members of the group called system is chadmin group=system root. This command will set the primary group of the root user to the system group, thereby limiting root user access to only members of that group. This command can be used to set any user's primary group, not just root." The source of this information is the IBM AIX v7 Administrator Specialty Study Guide.

NEW QUESTION # 40
A system administrator has noticed that static routes are missing after rebooting a system. What is the most likely reason for this?
- A. The administrator has failed to configure the routes in the inet0 device with the chdev command.
- B. The administrator has failed to run the cfgmgr command before rebooting the systems.
- C. The administrator has failed to configure the routes with the route add command.
- D. The administrator has failed to configure the routes in the lo0 device with the chdev command.
Answer: B
Explanation:
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.
