NEW QUESTION # 54
An administrator has a test server (my host) that uses local name resolution. The administrator arrives late one morning and finds that their co-worker was asked to make some changes to the IP address of the server.
The co-worker used SMIT from the console, but then when testing from the console, the following command fails:
ping my_host
Why did the ping fail?
- A. They didn't update the DNS entry.
- B. They didn't update /etc/hosts after mktcpip was run.
- C. They didn't reboot the server.
- D. They used an incorrect gateway address.
Answer: B
Explanation:
The /etc/hosts file is used by the system for local name resolution on the server, so if the IP address of the server has been changed, but the /etc/hosts entry has not been updated, the ping command will fail. This is explained in the IBM AIX v7 Administrator Specialty Study Guide, under the topic "Using the mktcpip Command".

When a user logs in, the session hangs after entering the password. What is the most likely cause of the problem?
- A. The file systems are full.
- B. There was a network failure.
- C. The /usr/sbin/passwd demon is not running.
- D. There are problems with the authentication mechanism.
Answer: D
Explanation:
If a session hangs after entering the password, it is most likely due to problems with the authentication mechanism. This could be due to issues with the configuration of authentication services, network delays in authentication if using network-based authentication (such as LDAP), or misconfigurations in the PAM (Pluggable Authentication Module) settings. The other options, such as thepasswddaemon, full file systems, or network failures, are less likely to cause a login hang at this stage.References:= IBM AIX Documentation

NEW QUESTION # 64
An administrator finds that their development server has crashed and an error code 554 is displayed. They know that this error is typically associated with a problem executing varyon rootvg and they should boot from AIX Media to be able to perform maintenance tasks. When the administrator checks the crontab of the NIM server, they find that a mksysb image is created each night.
Can the administrator use this mlcsysb to boot the server and perform the required maintenance tasks?
- A. Yes, but they may need to create a spot first.
- B. No, because they need to use the original AIX installation media for that server.
- C. Yes, but they may need to create a machine resource first.
- D. No, because mksysb is not bootable.
Answer: A
Explanation:
Amksysbimage can be used to boot an AIX system and perform maintenance tasks. However, when using Network Installation Management (NIM), the administrator may need to create a SPOT (Shared Product Object Tree) resource from themksysbimage. The SPOT resource provides the necessary boot files and maintenance environment to boot the client system and perform the required tasks, such as varying on therootvgand troubleshooting the issue.References: IBM AIX NIM Documentation
NEW QUESTION # 65

Which command will accomplish this?
- A. cruiser sugroups=system root
- B. chadmin user=root system
- C. chadmin group=system root
- D. chgroup admin=root system
Answer: A
Explanation:
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
NEW QUESTION # 66
A customer runs smit on the AIX command line and receives the message below:
1800-005 SMIT requires a minimum of 24 line by 80 column output display.
What can be done to resolve the error?
- A. Set the TERM variable to smit.
- B. Make sure they are running as the root user.
- C. Resize their window.
- D. Change their DISPLAY environment variable.
Answer: C
Explanation:
The root user is not required to run SMIT, and the size of the window is the only factor that determines the minimum output display requirements. According to the IBM AIX v7 Administrator Specialty Study Guide (page 9-3), SMIT requires 24 lines and 80 columns for the output display for successful execution.
NEW QUESTION # 67
An AIX system is defined as a NIM client with -a connect=shell. The client system is up and running. The client can ping the NIM master, and the master can ping the client. The administrator of the NIM master system attempts to use NIM to install software updates on the NIM client, but receives the error message Permission denied.
What can the administrator of the AIX NIM client do to help resolve the problem?
- A. Flush the arp cache and then reboot the client system to ensure the network route table is correct.
- B. Check that the root user's .rhosts file has an entry for the NIM master, and that the file permissions are
600. - C. Check the firewall configuration and open port 1066 if required.
- D. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
Answer: B
Explanation:
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.
NEW QUESTION # 68
While executing the following extendvg command, the system administrator receives the following error:
The administrator used the chvg -t command to fix the error.
What is the implication of running this command?
- A. It reduces the maximum number of files allowed within that volume group.
- B. It reduces the maximum number of physical volumes allowed within that volume group.
- C. It reduces the maximum file size allowed within that volume group.
- D. It reduces the maximum number of logical volumes allowed within that volume group.
Answer: B
Explanation:
The chvg command with the -t option is used to reduce the maximum number of physical volumes (PVs) allowed in a volume group (VG). This is necessary when the number of PVs in a VG exceeds the maximum allowed. Reference: IBM AIX v7 Administration Specialty Study Guide (section 10.3.3, pp. 641-642).
Thechvg -tcommand in AIX is used to change the factor by which the maximum number of physical partitions (PPs) per physical volume (PV) is increased. When this command is used to increase the maximum PPs, it allows more physical partitions on a physical volume, but it reduces the maximum number of physical volumes that can be included in the volume group. This is necessary when the required PPs exceed the current limit due to large disk sizes or large numbers of partitions.References: IBM AIX Documentation - chvg
