IBM AIX Test Quiz: Trivia!

The shell in the Unix system is responsible for providing a command-line interface for users to interact with the operating system. It acts as an intermediary between the user and the Unix system, allowing the user to input commands and receive output from the system. The shell also provides features such as command history, file redirection, and scripting capabilities through shell scripts, which allow users to automate tasks and execute multiple commands in sequence. Overall, the shell facilitates communication and interaction between the user and the Unix system.

AIX stands for Advanced Interactive eXecutive.

AIX comes with a backup utility called mksysb, which stands for "Make system backup". This utility is used to create backups of the entire system, including the operating system, applications, and data. It allows for easy restoration of the system in case of any failures or disasters.

PowerHA is a high availability software that provides continuous availability for critical applications. Unicast heart beating is a communication method used by PowerHA to exchange heartbeat messages between nodes in a cluster. This version of PowerHA, V7.1.3, supports unicast heart beating, allowing nodes to monitor each other's availability and ensure the continuity of services.

The different parts of the UNIX system include tools & apps and the kernel. Tools & apps refer to the various software programs and applications that are used in the UNIX system, such as text editors, compilers, and utilities. The kernel, on the other hand, is the core component of the UNIX system that manages the system's resources, controls hardware devices, and provides essential services to the user and other software programs. Shell scripts, although mentioned in the options, are not considered as separate parts of the UNIX system but rather a type of scripting language used to interact with the system.

The correct answer is to backup, delete, and recreate the filesystem to a new size. This involves creating a backup of the filesystem's data, deleting the existing filesystem, and then recreating it with the desired smaller size. This method allows for a more efficient use of disk space by reducing the size of the filesystem to match the actual data it contains.

The correct answer is "qdaemon:2:wait:/usr/bin/startsrc –sqdaemon" because this entry in the /etc/inittab file specifies that the qdaemon process should be started in the "wait" state. This means that the system will wait for the process to complete before moving on to the next entry in the file. The "/usr/bin/startsrc –sqdaemon" command is used to start the qdaemon process.

AIX is considered the premier UNIX platform today because it offers outstanding performance, improved efficiency through virtualization, and a strong, stable, non-disruptive roadmap. AIX excels in terms of performance, providing high-speed processing capabilities that can handle complex workloads efficiently. It also offers virtualization capabilities, allowing users to optimize resource utilization and improve overall efficiency. Additionally, AIX has a strong and stable roadmap, ensuring that users can rely on the platform for their long-term needs without disruptions.
