NEW QUESTION # 22
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 # 24
An AIX administrator is struggling with installing RPM packages. When they try to install a package, errors appear that there are prerequisite RPMs that also need to be installed. Which tool can be used to simplify resolving these dependencies?
- A. rpm
- B. dpkg
- C. yum
- D. installp
Answer: D
Explanation:
Installp is a command-line package management tool that is used in the AIX operating system to install, remove, and manage software packages. It simplifies the installation of RPM packages by automatically resolving any prerequisite dependencies and installing them before the main RPM package. This ensures that any prerequisites are installed and configured correctly before the main package is installed, reducing the time it takes to resolve installation issues. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 9-10).
NEW QUESTION # 25
While a system administrator is checking the TCP/IP connectivity between two systems with the traceroute command, the administrator found Fragmentation required messages in the traceroute output.
What is the likely reason for these messages?
- A. The TCP buffers in the router gateway are exhausted. The source and target system are having TCP/IP communication problems.
- B. Different MTU sizes between the source and target systems. The source system is using Jumbo Frames and the target is using the default MTU size.
- C. Same MTU sizes between the source and target systems. The source and target systems are using Jumbo Frames. The LPARs are using the same Virtual Switch (vSwitch) Network.
- D. The TCP buffers between the source and the target systems are exhausted. The source and target systems are using virtual ethernet adapters.
Answer: B
Explanation:
The source system is using Jumbo Frames and the target is using the default MTU size. Fragmentation required messages can appear in traceroute output when the Maximum Transmission Unit (MTU) size of the source and target systems are different. In this case, the source system is using a larger MTU size (Jumbo Frames) than the target system (default MTU size). As a result, the router gateway must fragment the data packets in order for them to reach their destination. This is why the fragmentation required messages appear in the traceroute output.

This will force the fsck command to check the file system for errors and attempt to fix them. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 8-23).
NEW QUESTION # 33
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 /etc/hosts after mktcpip was run.
- B. They didn't update the DNS entry.
- C. They used an incorrect gateway address.
- D. They didn't reboot the server.
Answer: A
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".
NEW QUESTION # 34
