Their knowledge base should also include the information about the hard and symbolic links as well as the creation, changing, and finding processes related to system files and their placement in the correct location. Also, this objective evaluates one’s ability to understand the correct locations of files under FHS, use links to support system administration tasks, create links, and skills in managing the access permissions on regular files, special files, as well as directories. It is important to have the expertise in using the group field to grant file access to group members, using labels and UUIDs for identifying and mounting file systems, repairing simple filesystem problems, and managing MBR and GPT partition tables.
- Linux Installation & Package Management: To cover the questions of this subject area, the candidates have to demonstrate their understanding of Linux as a virtualization guest, knowledge of installing the boot manager, designing hard disk layout, managing shared libraries, as well as knowledge of the Debian package management as well as RPM and YUM package management. They have to know how to backup boot options and provide alternative boot locations, install the boot loader and configure it, as well as install, upgrade and uninstall Debian binary packages. Also, you should know how to obtain information on the RPM packages, including version, dependencies, status, integrity, and signatures. In addition, the professionals need to have an understanding of the general concepts of virtual machines and containers as well as common elements of virtual machines in IaaS Cloud. It includes block storage and networking, computing instances, unique properties of a Linux system, which have to change when a system is cloned or used as a template, and Linux extensions that integrate Linux with a virtualization product.
- Unix Commands & GNU: This topic evaluate the learners’ proficiency in working on the command line, using streams, redirects, and pipes, processing text streams with the help of filters, as well as creating processes, monitoring them, and killing if needed. Their skill set should include the knowledge of modifying process execution priorities, basic file editing, and searching text files with the use of regular expressions. The test takers should also perform their skills in using single shell commands and one-line command sequences in order to perform basic tasks on the command line, as well as invoking commands inside and outside the defined path. It also includes the process of sending output streams and text files through the text utility filters in order to modify the output with the use of the standard UNIX commands that are found in the GNU textutils package. It is also required to have knowledge of how to copy, move, and also remove the directories and files individually, use simple/advanced wildcard specifications in commands, as well as use the output of one command as arguments to another command. A potential candidate has to be able to select and sort processes for display, run a program with higher or lower priority than the default, create simple regular expressions that contain several notational elements, configure the standard editor, and more.
