NEW QUESTION 14
When attempting to recover a corrupted file system an administrator runs the command fsck against the unmounted file system and receives the following error:
After confirming that the file system is not mounted, what should the administrator do next?
- A. Run logrcvr /dev/ulv14 .
- B. Convert the log to INLINE.
- C. Run fsck: with the -F (force) flag.
- D. Run logform /dev/u1v11.
Answer: C
Explanation:
When attempting to recover a corrupted file system, the administrator should first confirm that the file system is not mounted. If the file system is not mounted, then the administrator should run the fsck command with the -F (force) flag. 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 15

NEW QUESTION 17
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. No, because they need to use the original AIX installation media for that server.
- B. Yes, but they may need to create a machine resource first.
- C. Yes, but they may need to create a spot first.
- D. No, because mksysb is not bootable.
Answer: B
Explanation:
A mksysb image is a snapshot of the AIX operating system and its configuration, so it can be used to boot the server and perform the required maintenance tasks. However, in order to use the mksysb image, the administrator may need to create a machine resource in the NIM environment first. According to the IBM AIX v7 Administrator Specialty Study Guide (page 13-6), the mksysb image should be used in combination with a previously created machine resource, which defines the parameters for the installation.
NEW QUESTION 18
What are three states a device can have when connected to an AIX system?
- A. Running
- B. Defined
- C. Blocked
- D. Stopped
- E. Available
- F. Suspended
Answer: B,D,E
Explanation:
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.

This image contains a backup of the rootvg volume group of the system, which includes all the operating system files, configuration files and installed applications. 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.cmds3/mksysb.htm.
NEW QUESTION 20
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. Reference: IBM AIX v7 Administrator Specialty Study Guide.
NEW QUESTION 21

Answer: B
NEW QUESTION 24
Which user account is always UID 0 on AIX?
- A. admin
- B. system
- C. root
- D. bin
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.
