Elaborate about SELinux?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Talking about SELinux, it is a Linux program with enhanced security features. SELinux keeps the server protected from compromise and misconfiguration. This is sued to access the control implementation for the Linux Kernel. It puts a limit and then instructs the servers to only access the particular files and security policies.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"15_While_installing_Apache_what_is_the_web_port_used_to_serve_web_pages\"><\/span><span class=\"s1\">15. While installing Apache, what is the web port used to serve web pages?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Well, most of the web servers operate on Port 80. So, while installing Apache, it automatically defaults to Port 80. However, users can use some alternative ports. But this will force them to type a port into a browser to get access to the website. You can also use Port 8080 for this.\u00a0<\/span><\/p>\n<blockquote><p>Linux Blogs are the good source to learn about the latest Linux news, updates, trends, strategies etc. Here is the list of 20 <a href=\"https:\/\/www.whizlabs.com\/blog\/best-linux-blogs\/\" target=\"_blank\" rel=\"noopener noreferrer\">best Linux Blogs and websites<\/a>!<\/p><\/blockquote>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"16_Explain_about_rgmanager_and_CMA\"><\/span><span class=\"s1\">16. Explain about rgmanager and CMA?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: This is one of the most complex\u00a0Red Hat Linux System Administrator interview questions.\u00a0So, while answering it, remember to tell transparently. In the Red Hat cluster, Cman works as a cluster manager, especially a distributed cluster manager. It operates in a cluster node. Talking about its functions, it effectively tacks the cluster quorum by observing the cluster nodes. Cman is responsible for a quorum, voting, communication, and monitoring between clusters.\u00a0<\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Coming to the rgmanager, it is a resource group manager. Rgmanager is responsible for collecting cluster resources defined as resource trees, resource groups, and services. This dramatically helps a Red Hat administrator to define, monitor, and configure the cluster services. When a node fails to work, it will locate that particular clustered service to other nodes without affecting the services.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"17_Explain_the_runs_levels_and_how_to_alter_them\"><\/span><span class=\"s1\">17. Explain the runs levels and how to alter them?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In Linux, a run level is a stage of initialization that effectively defines what types of system services are functioning. They are generally defined by numbers. In general, there are a total of 7 run levels in the Linux system, and they serve a different purpose. They are:<\/span><\/p>\n<ul class=\"ul1\" style=\"text-align: justify;\">\n<li class=\"li1\"><span class=\"s1\">Halt system (Sued to turn off the system)<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Basis multi-user mode but there will be no NFS<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Single users mode<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Full multi-user mode (based on the text)<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Multi-user mode (graphical UI)<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Unused<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\">Reboot system<\/span><\/li>\n<\/ul>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Now talking about the process for changing the level, one needs to change the file &#8211; \/etc\/inittab. Alter the initdefault entry (id:5: initdefault:). If the users want to alter the run level on the fly, they can do it through the \u2018init\u2019 command. Let\u2019s take an example.\u00a0<\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">When a user types Init 3 in the command line, this will shift the system to run level 3 from run level. To list the current level, the users can use the command \u201cWho -r.\u201d\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"18_Can_you_explain_DAS\"><\/span><span class=\"s1\">18. Can you explain DAS?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: This is one of the common\u00a0Red Hat Linux System Administrator interview questions\u00a0that every employer asks. However, the answer is quite simple. It is, generally, a block device physically connected to the host machine. It comes with a filesystem. Only certain servers can access the device. You can find such storage devices, near-dedicated resources, and server storage. The DAS is inexpensive and easy to use. It covers SATA and SCSI technologies.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"19_Tell_me_about_the_load_balancing_cluster\"><\/span><span class=\"s1\">19. Tell me about the load balancing cluster?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: As the name suggests, the load balancing cluster utilized to balance the load throughout the cluster nodes. It works when the cluster dispatches the service request to a different cluster node. This cluster offers inexpensive scalability as multiple nodes can be configured considering the load requirements. In this cluster, if a node is not working correctly, it will then detect the failure and then assign required requests to available nodes. Here the collapse of the node will not be visible outside the cluster.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"20_What_do_you_mean_by_LVM\"><\/span><span class=\"s1\">20. What do you mean by LVM?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In Red Hat Linux, LVM refers to Logical Volume Mangere. It is the storage management solution that lets the Red Hat Linux System Administrators split the space of hard drive into PV- Physical Volumes. After that, PV is combined into VG- Volume Groups. The VG can be further divided into LV- Logical Volumes.\u00a0<\/span><\/p>\n<p><a href=\"https:\/\/www.whizlabs.com\/red-hat-certified-engineer-rhce\/\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2019\/02\/RHCE-Online-Course.gif\" alt=\"RHCE Online Course\" \/><\/a><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"21_Elaborate_the_process_for_creating_LVM\"><\/span><span class=\"s1\">21. Elaborate the process for creating LVM?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: When talking about\u00a0Red Hat Linux System Administrator interview questions,\u00a0we can\u2019t ignore this question. You need to elaborate it steps by steps. First, users need to create physical volumes. For this, they can use the command \u201cpvcreate\u201d (#pvcreate \/dev\/sda2). After establishing that, they need to add the physical volume to the volume group. Here \u201cvgcreate\u201d command can be used (#vgcreate VLG0 \/dev\/sda2). Now, from the volume group, create a logical volume. Use the \u201clvcreate\u201d command (#lvcreate -L 1G -n LVM1 VLG0). In the last step, the users need to use the \u201cmke2f\u201d command to make a file system on Sda2 (#mke2fs -j \/dev\/VLG0\/LVM1).\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"22_Clearly_explain_the_Indoes_and_their_uses_in_Red_Hat_Linux\"><\/span><span class=\"s1\">22. Clearly explain the Indoes and their uses in Red Hat Linux?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: It refers to a data structure of a file system found in Unix like OS. It stores all the necessary information about the file. However, it doesn\u2019t use the actual name. The inode helps in the process of recovering the files systems, which are damages. If there is any lost inode, you can locate it in \u201clocate + found\u201d directory. Remember that this question comes under the most frequently asked\u00a0Red Hat Linux System Administrator interview questions.\u00a0So, keep the answer in your mind.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"23_Tell_us_about_SAN_and_NAS\"><\/span><span class=\"s1\">23. Tell us about SAN and NAS?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In Red Hat Linux, NAS runs an embedded OS on the basic hardware, for example, keyboard and monitor. Its primary purpose is to verify the clients and offer to share with the multiple systems or users to a particular network that needs dedicated IP to work. On the other side, SAN is a perfect storage solution at the block-level. It is primarily developed to handle high volume data transfer. In terms of performance and capacity, this is perfectly scalable.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"24_Elaborate_about_sgid_and_suid_terms\"><\/span><span class=\"s1\">24. Elaborate about sgid and suid terms?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Talking about suid, it offers the same level of ownership permissions while a user executes a file. Coming to the sgid, it comes with a group of privileges of a completed file. It inherits the ownerships while developing the directory.\u00a0<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"25_Can_you_tell_me_about_the_bootloader_Give_us_a_short_description\"><\/span><span class=\"s1\">25. Can you tell me about the bootloader? Give us a short description.<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: One of the easiest\u00a0Red Hat Linux System Administrator interview questions\u00a0in the interview. The answer is very simple. Just tell the recruiter that bootloader boots the operating system. Besides, it takes the decision about the kernel from which the operating system will boot.<\/span><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"26_Do_you_know_what_is_%E2%80%9Cparted%E2%80%9D_Command_If_yes_then_tell_why_it_is_used\"><\/span><span class=\"s1\">26. Do you know what is \u201cparted\u201d Command? If yes, then tell why it is used?\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In Red Hat Linux, parted is a popular command, or you can say a tool that lets the users manage the hard disk partitions easily. This can help you in deleting, adding, extending, and shrinking hard disk partitions and file systems. However, with time it has gone through several changes. Some of its old features are now replaced with new ones.<\/span><\/p>\n<blockquote><p><span class=\"s1\">Aspired to become Red Hat Certified Engineer?
