Accomplishing the LPIC-3 304-200 exam signifies your brilliance in enterprise-level high availability and virtualization. It means that you are adept at handling complex tasks related to Linux administration. This specific test is targeted to experienced Linux professionals who have an active LPIC-2 accreditation.
Main Details about the LPIC-3 Certificate
LPIâ€™s 304-200 exam is the main requirement for LPIC-3. This is actually the highest-tier of the Linux Professional certification program and is valid for up to 5 years. Having this kind of endorsement verifies your competence in technical enterprise aspects, particularly virtualization functionalities and high availability clusters.
Significant Exam Information
The LPIC-3 accreditation is rewarded to those who successfully pass 304-200 exam. This test runs for up to 90 minutes, with a total of 60 questions in a fill-in-the-black and multiple-choice format. As for the cost, it depends on your location, though the general fee is $200. To better understand what you are going to face, letâ€™s dive into core objectives.
Important Topics Covered in the Exam
The LPIC-3 304-200 exam topics are categorized into three primary domains. Each of them has a corresponding percentage that indicates the weight of a particular objective. Henceforth, ones with higher percentages come with more questions. The exact weighting values are thoroughly presented in the official blueprint. Nevertheless, itâ€™s still a must that you fully and equally understand each topic. Whatever training materials you use, always remember that the individual test objectives are the staple of your study plan.
The first major area is about virtualization. It commences with the concepts, theories, and basic terms such as hypervisor, HVM, PV, CPU flags, IaaS, SaaS, and PaaS. The pros and cons of virtualization, along with its migration and variations are explained as well. Next in line is Xen version 4.x. Some of the knowledge extents covered are Xen architecture, storage, networking, configuration, and utilities. You also need to study the tasks related to Xen installation and troubleshooting. In addition to that, there will be an elaboration on XAPI, Xen Boot Parameters, XenStore, and xm utility.
Another major facet of virtualization is the Kernel-based Virtual Machine, or commonly known as KVM. At this point, you have to learn more about its entire architecture and relevant features. For the terminologies, these include Kernel modules, KVM monitor, qemu-img, /etc/kvm/, and /dev/kvm. Virtualization solutions are also noteworthy topics incorporated in this domain. These speak about OpenVZ, LXC, VirtualBox, docker, together with other virtualization technologies and provisioning tools. And for the last two subdivisions of this module, these give focus on Libvirt and cloud management tools.
- High Availability (Cluster Management)
After virtualization, we have high availability. Letâ€™s kick off this area with some fundamental terms such as cluster, quorum, split brain, fencing, redundancy, replication, disaster recovery, session handling, MTBF, MTTR, and SLA. Moreover, itâ€™s a must to gain knowledge about cluster architectures and their reorganization mechanisms as well as high availability application and operational consideration.
The subsequent parts that also need your mastery are load balanced clusters and failover clusters. This subject matter provides you with comprehensive experience in installing, configuring, upholding, and troubleshooting the said high availability attributes. For load balanced clusters, the pivotal aspects covered are LVS, IPVS, VRRP, HAProxy, keepalived, Idirecord, and backend server. Failover clusters, on the other hand, take on the functionalities associated with the pacemaker architecture. This involves its key components such as CRMd, LRMd, CIB, DC, PEngine, and STONITHd, along with resource classes, features, rules, and constraints. Likewise, you need to mug up your comprehension in pacemaker cluster arrangement and management via pcs and crmsh.
The last scope is about high availability to be used in enterprise Linux distributions. This is where you obtain insights on Red Hat Enterprise Linux High Availability Add-On and SUSE Linux Enterprise High Availability Extension. In addition, this area demonstrates the distribution of specific config tools and amalgamation of load balancers, cluster engines, filesytems, and storage technology.
- High Availability (Cluster Storage)
Now, weâ€™ve reached the last domain of the exam and that is the cluster storage features of high availability. This domain is divided into two major sections â€• Distributed Replicated Block Device (DRBD)/ Clustered Logical Volume Manager (cLVM) and Cluster File Systems. The first part refines your skills in administering DRDB devices, particularly integrating with Pacemaker and configuring LVM. But before that, you need to understand the fundamental DRBD resources, devices, states, networking, and replication. With your basic skills, it will be much easier to configure, manage, and troubleshoot significant DRDB features.
The second part, which is clustered file systems, talks more about GFS2 and OCFS2. It walks you through the principles of cluster file systems so you can efficiently build, maintain, and troubleshoot GFS2 and OCFS2 file systems in a specific cluster. Integration of the said file systems with Pacemaker is considered as a key exam area as well. To complete the list, you must have a solid familiarity with the O2CB cluster stack and other clustered file systems in a Linux set-up.
Career Opportunities for Successful Passers
Linux professionals are well-acclaimed in the tech industry â€• much more if you are certified by the renowned Linux Professional Institute (LPI). With the LPIC-3 certificate, it opens up a chain of incredible career opportunities that ultimately make you an in-demand professional. In fact, LPIâ€™s certification program is considered a global standard for open source candidates.
Aside from better job security, your LPI accreditation boosts your salary range. For IT managers, they earn an average salary of $89k while IT directors get around $121k, as stated on PayScale. Lower-rank professionals like IT specialist receive $58k as wage. In general, LPIC-3 holders enjoy at least $85k.
Career Path after this Certification
As mentioned earlier, LPIC-3 is already the highest level for LPIâ€™s accrediting curriculum. Though there are no other advanced certifications, you can still branch out your specialty with Enterprise Virtualization and High Availability or Enterprise Security. Another option is to take one of the LPIâ€™s certifications related to the Open Technology category, choosing either DevOps Tools Engineer or BSD Specialist.
