IT Operations & Infrastructure

A practical guide to block, file, and object storage, SAN vs NAS, storage networking, performance, resilience, cloud platforms, and architecture decisions.

A customer wants a storage plan that supports file services, analytics, a hybrid-cloud footprint and rapid recovery after a security incident. Product…

A mid-sized enterprise wants to modernize a crowded storage estate without rewriting every application. One proposal promises faster arrays; another…

An operations manager is comparing storage proposals and hears unfamiliar acronyms: SAN, NAS, object storage, controllers and cloud tiering. Each vendor…

Microsoft 98-349 was the Microsoft Technology Associate Windows Operating System Fundamentals exam. Microsoft retired the entire MTA program, including Windows Operating System Fundamentals, on June 30, 2022. The ExamSnap Microsoft 98-349 page is therefore historical and should not be presented as an exam that new candidates can schedule today. The old syllabus still has educational value because it covered core client-operating-system concepts: editions and configuration, installation and upgrades, applications, file and share permissions, devices, maintenance, and basic Windows administration. Those foundations continue to matter, but the examples and product assumptions…

LPI 702-100 is the current version 1.0 exam for the LPI BSD Specialist certification. It covers practical administration across FreeBSD, NetBSD, and OpenBSD rather than treating BSD as a single interchangeable operating system. The ExamSnap LPI 702-100 page is the live exam destination, and the ExamSnap BSD Specialist page provides the certification-level route. Candidates need a solid Unix command-line foundation, but the exam goes further by asking how installation, software management, storage, system startup, users, processes, networking, and security differ across the three BSD families. The same command or file…

LPI 305-300 is the current version 3.0 exam for LPI LPIC-3 Virtualization and Containerization. It covers hypervisor concepts, Xen, QEMU/KVM, libvirt, disk-image management, Linux container internals, LXC/LXD, Docker, orchestration, and automated provisioning. The ExamSnap LPI 305-300 page is the live exam destination. The exam is strongest when virtual machines and containers are studied as different isolation models rather than as competing brands. Candidates should understand where hardware virtualization ends, where Linux namespaces and cgroups begin, how storage and networking are attached, and how orchestration and image provisioning change day-two operations….

LPI 300-300 is the current version 3.0 exam for LPI LPIC-3 Mixed Environments. It focuses on enterprise Linux integration with Samba, SMB, Microsoft Active Directory, Kerberos, LDAP, name resolution, identity mapping, file services, and cross-platform administration. The ExamSnap LPI 300-300 page is the live exam destination. This is not a basic file-sharing exam. Candidates are expected to understand how Linux systems participate in Windows-centered identity and resource environments, how Samba can operate in several roles, how authentication and name resolution interact, and how access behavior changes when Unix and Windows…

LPI 201-450 is the first current exam for LPI LPIC-2 version 4.5. It covers capacity planning, the Linux kernel, system startup, filesystems and devices, advanced storage administration, networking configuration, and system maintenance. The ExamSnap LPI 201-450 page is the live exam destination. This is a professional administrator exam, so candidates should already be comfortable with LPI LPIC-1 material. The challenge is no longer simply knowing commands; it is interpreting system state, planning capacity, recovering from failures, managing advanced storage, and troubleshooting networking across a small or medium environment. Build preparation…

LPI 102-500 is the second current exam required for LPI LPIC-1 version 5.0. It covers shells and shell scripting, user interfaces, administrative tasks, essential system services, networking fundamentals, and security. The ExamSnap LPI 102-500 page is the live exam destination. Where LPI 101-500 focuses heavily on architecture, packages, commands, and storage, this exam moves toward day-to-day administration. Candidates need to manage users, schedule tasks, configure locale and time, understand logging and mail basics, troubleshoot networking, secure remote access, and write useful shell scripts. The best study method is to build…

LPI 101-500 is the first of two current exams required for LPI LPIC-1 version 5.0. It focuses on system architecture, Linux installation and package management, GNU and Unix commands, devices, filesystems, and the Filesystem Hierarchy Standard. The ExamSnap LPI 101-500 page is the live exam destination. The exam rewards broad command-line literacy and a clear model of how Linux boots, discovers hardware, stores files, manages packages, and exposes devices. Candidates should expect both multiple-choice and fill-in-the-blank questions, so exact command names, files, and common options still matter alongside conceptual understanding….

LPI 050-100 is the current Open Source Essentials exam from the Linux Professional Institute. It is version 1.0 and covers software fundamentals, open source software licenses, open content licenses, open source business models, project management, and collaboration. The ExamSnap LPI 050-100 page is the current exam destination. This is not a Linux administration exam. Its value comes from understanding how open source software is built, licensed, governed, funded, released, and maintained across technical and business contexts. Developers, managers, legal professionals, product teams, and community contributors can all encounter the same…

LPI 010-160 is the current Linux Essentials exam, version 1.6, from the Linux Professional Institute. It is designed for candidates building foundational Linux and open source knowledge rather than experienced administrators pursuing the professional LPIC track. The ExamSnap LPI 010-160 page is the live exam destination. The certificate covers the Linux community and open source, basic command-line use, Linux operating-system concepts, security and permissions, and the practical skills needed to work with files, processes, scripts, and simple networks. The exam is approachable, but candidates still need to understand why commands…

Linux Foundation LFCS is the current hands-on Linux system administration credential from the Linux Foundation. The exam is distribution agnostic and tests practical administration across operations and deployment, networking, storage, essential commands, and users and groups. The ExamSnap Linux Foundation LFCS page is the current preparation target. Unlike a multiple-choice foundation exam, Linux Foundation LFCS rewards the ability to complete tasks under time pressure on a working system. Knowing that a feature exists is not enough. Candidates need repeatable command-line workflows for diagnosing processes, managing services, installing software, configuring storage…

Linux Foundation LFCA is the current entry-level Linux Foundation credential for broad modern IT knowledge. The exam was updated in September 2025 and now weights system administration fundamentals most heavily, followed by cloud computing, Linux, security, DevOps, and IT project management. The ExamSnap Linux Foundation LFCA page is the live exam destination. This breadth is the main challenge. A candidate may understand Linux commands but still lose points on cloud economics, security, disaster recovery, containers, Git, project concepts, or software architecture. The right preparation strategy is therefore to build connections…
