Which command should be used to perform a graceful shutdown and reboot of an AIX LPAR?

What are three states a device can have when connected to an AIX system?
- A . Available
- B . Defined
- C . Stopped
- D . Blocked
- E . Running
- F . Suspended
A,B,C
Explanation:
Devices that are connected to the system can be in one of four states.
Devices that are connected to the system can be in one of the following states:
Item
Description
Undefined
The device is unknown to the system.
Defined
Specific information about the device is recorded in the customized database, but it is unavailable to the system.
Available
A defined device is coupled to the operating system, or the defined device is configured.
Stopped
The device is unavailable but remains known by its device driver.
If a tty device and a printer alternately use the same tty connector, both a tty device and a printer are defined on the same parent and port in the device configuration database. Only one of these devices can be configured at a time. When the tty connector is configured, the printer specific setup information is retained until it is configured again. The device is not removed; it is in the defined state. Maintaining adevice in defined state retains customized information for a device that is not currently in use, either before it is first made available or while it is temporarily removed from the system.
If a device driver exists for a device, the device can be made available through the device driver.

What AIX feature will allow data to be mirrored to a remote site?
- A . Remote Volume Groups
- B . Geographic Logical Volume Manager
- C . Asynchronous Dispersed Logical Volumes
- D . Mirror Pools
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?
- A . Perform a debug boot of AIX and diagnose/fix the problem.
- B . Perform a maintenance mode boot of AIX and diagnose/fix the problem.
- C . Reinstall AIX or restore from a mksysb.
- D . Restart the system.
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 used an incorrect gateway address.
- C . They didn’t update the DNS entry.
- D . They didn’t reboot the server.
Which command lists filesets that are below AIX V7.2 technology level 4?
- A . oslevel -r -1 7200-04
- B . lslpp -s -1 7200-04
- C . lppchk: -L -F "fileset level" I grep -v "7200-04"
- D . instfix -i I grep -v 7200-04
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 name server when the first name server is not reachable.
- B . It causes ssh connections to disconnect after 1 minute of no activity.
- C . It reduces the failover time to the secondary NTP Server when the first NTP Server is unavailable.
- D . It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
The administrator of an AIX NIM client system has accidentally removed the /etc/niminfo file.
Which method is used to rebuild the /etc/niminfo file?
- A . Use the nimclient command to restore the /etc/niminfo file from the most recent mksysb backup image.
- B . Use the rep command on the AIX client system to copy the /etc/niminfo file from the NIM master.
- C . Use the nimclient command on the AIX client system to rebuild the /etc/niminfo file.
- D . Use the niminit command on the AIX client system to rebuild the /etc/niminfo file.
When configuring an LPAR profile, what is the meaning of CPU Entitlement?
- A . the count of virtual CPUs configured on an LPAR
- B . the number of logical CPUs allocated to an LPAR
- C . Simultaneous Multi Threading setting of an LPAR
- D . the amount of guaranteed CPU time allocated to an LPAR
What is a benefit of using mksysb to backup a system?
- A . The image contains a backup of all file systems.
- B . The image can be used to restore the rootvg volume group of the system.
- C . The image contains a backup of all application and user data.
- D . The image contains a backup of all volume groups and logical volumes.
