Question1: To meet new security requirements, it has been decided that telnet will no longer be allowed in the development environment. The administrator of the AIX development server needs to prevent users from being able to access this server using telnet.
When checking /etc/inetd.conf, the administrator sees the following line:
telnet stream tcp6 nowait root /usr/sbin/telnetd telnetd -a
What would stop the telnet daemon from running and restarting after reboot?

Question2: The lspv and Iquerypv commands show a different PVID for an hdisk. How is this possible?

After confirming that the file system is not mounted, what should the administrator do next?

Question4: When the system boots it stops and displays reference code 551. This reference code means the rootvg will not varyon. What is the best way for the administrator to proceed?

Question5: A customer wants to install an open source file, but finds that the rpm command is not installed. With which program can they install rpm?

Question6: While trying to extend a file system named /work an administrator receives the following error. 0516-787 extendlv: Maximum allocation for logical volume fslv00 is 256.
What must be done to allow the file system to be extended?

Question7: Which AIX command lists the implementation and defined resources of an LPAR?

Question8: When a user logs in, the session hangs after entering the password. What is the most likely cause of the problem?

Question9: A security auditor requires the administrator to disable direct root login to an AIX system. Where should the administrator check to see if the root login has been disabled?

Question10: An administrator is responsible for managing some AIX partitions. Which command would the administrator run to retrieve the configuration of a running partition, including configured devices?

Question11: An administrator encountered a problem creating a mksysb backup image on a system.
To investigate the problem further, the following information was collected


Based on this information, why has the creation of the mksysb backup image failed?

Question12: A customer checks their paging space on an AIX LPAR and sees the following output:
Page SpacePhysical VolumeVolume GroupSize%UsedActiveAutoTypeChksum
pagingOOhdisk2pgvg4576MB12yesnoIv0
hd6hdisklrootvg512MB99yesyesIv0
They want to have pagingOO be active after the next reboot. Which command should be issued to accomplish this?

Question13: 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?

Question14: 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?

Question15: A client is running multiple AIX, IBM i and Linux partitions on an IBM Power E980 system. Which command allows the administrator to check the number of processors, amount of memory, and list the devices on the AIX partition?

Question16: 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:

The tool asks for their current system firmware level. How can the administrator confirm what it is?

Question24: Which statement is true regarding Ethernet adapter MTU size settings?

Question25: Which configuration will provide an LPAR network resilience and better performance with two ethernet adapters?

Question26: A customer calls to complain about slow workload performance but offers no additional details. What should the administrator do next?

Question27: Which statement is true regarding the snap command?

Question28: 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?

Question29: An administrator starts an AIX LPAR and wants to monitor the boot process using the HMC console.
Which command in HMC SSH session lists all managed systems, LPARs on them and offers an easy way to open a console window to an AIX LPAR?
