NEW QUESTION # 34
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. 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.
- 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. The TCP buffers in the router gateway are exhausted. The source and target system are having TCP/IP communication problems.
- 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.

The administrator must perform a maintenance mode boot to diagnose the problem."
NEW QUESTION # 41
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 causes ssh connections to disconnect after 1 minute of no activity.
- B. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
- C. It reduces the failover time to the secondary name server when the first name server is not reachable.
- D. It reduces the failover time to the secondary NTP Server when the first NTP Server is unavailable.
Answer: A

NEW QUESTION # 44
Which user account is always UID 0 on AIX?
- A. admin
- B. bin
- C. root
- D. system
Answer: C
Explanation:
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 # 45
A SAN administrator increased the size of a LUN device (hdisk) that is being used by a AIX LPAR. However, the system administrator does not see the new size using the lsvg or Ispv commands.
Which command updates the system with the new size?
- A. chvg -g
- B. synclvodm
- C. extendpv
- D. cfgmgr
Answer: D
Explanation:
The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.
NEW QUESTION # 46
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. Check that the root user's .rhosts file has an entry for the NIM master, and that the file permissions are 600.
- B. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
- C. Flush the arp cache and then reboot the client system to ensure the network route table is correct.
- D. Check the firewall configuration and open port 1066 if required.
Answer: A
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.

The -A flag is used to list the microcode level and the active microcode level of the system. This command can be used to confirm the system firmware level which is required to use the IBM Fix Level Recommendation Tool (FLRT).
NEW QUESTION # 49
An administrator does not receive a console login prompt after booting a system (the HMC shows the system as running and there are no reference codes). What are two potential reasons for this?
- A. The disks have been rezoned to exclude this host.
- B. The file systems are full.
- C. The rootvg has been overwritten.
- D. inittab entries before the console login have not completed running.
- E. There is no console entry in inittab.
Answer: D,E
Explanation:
If an administrator does not receive a console login prompt after booting a system, two potential reasons could be:
* Inittab entries before the console login have not completed running. The/etc/inittabfile controls the initialization process, and if prior entries are hanging or taking a long time to complete, it can prevent the console login from appearing.
* There is no console entry in the/etc/inittab. The absence of a console entry means the system does not know to start a console login process, which would prevent the login prompt from appearing. Other reasons like full file systems, rezoned disks, or overwritten rootvg could cause system issues but would not specifically prevent the console login prompt from appearing if the system is running.References:= IBM AIX Documentation
NEW QUESTION # 50
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 mksysb to boot the server and perform the required maintenance tasks?
- A. Yes, but they may need to create a spot first.
- B. Yes, but they may need to create a machine resource first.
- C. No, because they need to use the original AIX installation media for that server.
- D. No, because mksysb is not bootable.
Answer: A
Explanation:
Yes, the administrator can use themksysbimage to boot the server and perform the required maintenance tasks, but they may need to create a SPOT (Shared Product Object Tree) first. A SPOT is required in the Network Installation Manager (NIM) environment to boot a client machine from amksysbimage. The SPOT provides the necessary resources, such as the boot image and other files needed for network boot and system maintenance.References:= IBM AIX NIM mksysb Backup and Recovery Documentation
NEW QUESTION # 51
An AIX administrator would like to create an account called adm. Which is the issue with creating this account?
- A. It is an RBAC role in AIX. Users can't be named after RBAC roles on AIX.
- B. There will be no problems. The root user can create any accounts.
- C. It is a standard AIX account and is delivered with AIX.
- D. It is a reserved word in AIX and cannot be used for accounts.
Answer: C
Explanation:
The account name "adm" is a standard account that comes pre-installed with AIX. It is used for system administration tasks and has specific roles and permissions associated with it. Attempting to create a new account with the same name would conflict with the existing standard account, hence it cannot be used for creating a new user account.References:= IBM AIX Documentation
NEW QUESTION # 52
What is a benefit of using mksysb to backup a system?
- A. The image contains a backup of all file systems.
- B. The image contains a backup of all application and user data.
- C. The image contains a backup of all volume groups and logical volumes.
- D. The image can be used to restore the rootvg volume group of the system.
