S1000-007 IBM AIX v7 Administrator Specialty Free Practice Exam Questions (2025 Updated)

The commandvmstat -vis used to review the cumulative count of blocked I/Os. This command provides various virtual memory statistics, including information about blocked I/Os, which helps indiagnosing performance issues related to input/output operations.References:= IBM AIX vmstat Command Documentation

The logical volumedatalvhas 30 Logical Partitions (LPs), each of 1024 megabytes (MB), or 1 gigabyte (GB). Therefore, the total usable size of the logical volume is 30 LPs * 1 GB per LP = 30 GB.References:= IBM AIX Documentation

Thesmit.scriptfile records all commands executed through SMIT (System Management Interface Tool). By checking this file, the administrator can find the exact command that was run previously. This log file is useful for auditing and replicating commands executed via SMIT.References:= IBM AIX Documentation

Therpmcommand is used to install, update, and manage packages from the AIX Toolbox for Linux Applications. This toolbox provides GNU and open source tools for AIX, and therpmcommand handles the package management of these tools.References:= IBM AIX Toolbox for Linux Applications

The/etc/motd(Message of the Day) file is used to display a message to all users upon logging in to the server. When configured, this file ensures that the specified message is shown to users who access the server via SSH or other login methods.References:= IBM AIX Documentation

Mirror pools in AIX allow administrators to define specific sets of disks that can be used for mirroring logical volumes. This feature provides greater control over the allocation of mirror copies, ensuring that each copy is placed on separate, specified disks to improve data redundancy and reliability. This setup helps in managing disk utilization and performance more efficiently. The other options do not accurately describe the primary benefit of mirror pools.References:= IBM AIX Documentation

Theprintqaccount is associated with printing capabilities in AIX. If the new system does not require any printing capabilities, theprintqaccount can be safely removed from the system.References:= IBM AIX User Account Management Documentation

Theimportvgcommand in AIX reads the Volume Group Descriptor Area (VGDA) and the Physical Volume ID (PVID) of the disks to identify and import volume group members. The VGDA contains metadata about the volume group, including information about logical volumes and physical volumes. The PVID is a unique identifier assigned to each physical volume, helping the system recognize and manage the disks within a volume group. The other elements, such as LVID, UUID, and UDID, are not used by theimportvgcommand for this purpose.References:= IBM AIX Documentation

AIX allows for the management of subsystems on remote systems through the System Resource Controller (SRC). This means that an administrator can issue commands to start, stop, or restart subsystems on remote AIX systems. Thesrcmstrprocess does not need to be halted to restart subsystems, and not all subsystems can be restarted using therefreshcommand.References:= IBM AIX Documentation

To upgrade from one release of AIX to another (such as from AIX 7.1 to AIX 7.2), the recommended method is a Migration Install. This method allows the administrator to upgrade the operating system while preserving existing data and settings. It updates the existing AIX installation to the new version, ensuring compatibility and continuity of system configurations and installed applications. The other methods, such as Preservation Install, New and Complete Overwrite Install, and Update Install, are either not suitable for upgrading to a new release or would result in data loss or incomplete updates.References:= IBM AIX Documentation

To prevent the telnet daemon from running and restarting after a reboot, the administrator should comment out the line related to telnet in the/etc/inetd.conffile by inserting a#at the beginning of the line. After making this change, running therefresh -s inetdcommand will apply the changes to theinetdservice without requiring a system reboot. This effectively disables the telnet service.References:= IBM AIX Documentation

When a file system corruption error is reported in the system error log, the appropriate action is to check the error log for specific details, unmount the affected file system, and run thefsck(file system check) command. This command checks and repairs inconsistencies and errors in the file system, which can help resolve the corruption issue. It is essential to unmount the file system before runningfsckto avoid further data corruption.References:= IBM AIX Documentation

The commandprtconfprovides detailed information about the configuration of a running partition, including the configured devices. This command outputs the current state of the system, making it useful for administrators to retrieve configuration details.References:= IBM AIX prtconf Command Documentation

In the/etc/exportsfile, the absence of specific permissions next to the/tmpdirectory implies that it is exported with the default read-write permissions. The/datadirectory has-rospecified, indicating read-only permissions, and/usr/manhas-root=client1, giving root access toclient1with default read-write permissions. Since no special permissions are indicated for/tmp, it retains the default read-write permissions.References: IBM AIX NFS Documentation

 Theyumtool can be used to simplify the installation of RPM packages by automatically resolving and installing prerequisite dependencies.yumis a package manager that handles the retrieval and installation of packages from repositories, making it easier to manage dependencies compared to manually using therpmcommand.References: IBM AIX Documentation – yum

When a customer calls with a complaint about slow workload performance, it is important to ask for additional details to help pinpoint the source of the issue. This could include details such as which application or process is running slowly, what errors are appearing, how long the issue has been occurring, etc. Having this information will help the administrator to determine the cause of the problem and determine the best course of action. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 5-29).

When a customer reports slow workload performance without additional details, the first step should be to gather more information. This includes asking specific questions about the nature of the workload, when the slowdown occurs, any recent changes to the system, and other pertinent details. This information is crucial for diagnosing the issue accurately and determining the appropriate course of action. Arbitrarily increasing resources like CPU or memory without understanding the root cause may not resolve the issue and can lead to inefficient resource usage.References: IBM AIX Performance Tuning Guide

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.

Themlcvtermcommand is used to open a console to an AIX virtual machine that is controlled by a Hardware Management Console (HMC). According to the IBM AIX v7 Administrator Specialty Study Guide, themlcvtermcommand allows you to open a terminal window to the console of a logical partition (LPAR) running AIX.

The superstrict mirror write consistency policy is the most reliable policy for achieving data consistency between mirrors in AIX V7.2. This policy will maintain the data consistency between mirrors by writing the data to both mirrors before the write operation is acknowledged as complete.
