Microsoft AB-100 is the current Agentic AI Business Solutions Architect exam and a requirement for the Microsoft Certified: Agentic AI Business Solutions Architect Expert credential, together with an eligible prerequisite Associate certification. The ExamSnap Microsoft AB-100 page is the live exam destination, while the ExamSnap Agentic AI credential page provides certification-level context. Microsoft’s study guide specifies skills measured for the English-language AB-100 exam as of October 14, 2026. The published weighting is 25–30% planning AI-powered business solutions, 25–30% design, and 40–45% deployment. Candidates should consult the dated Microsoft study guide,…

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…

Microsoft Exam 77-728 still presents an unusual 2026 status. Microsoft Learn currently lists Exam 77-728: Microsoft Excel Expert (Office 2016) with “retirement date: none” and a scheduling option. At the same time, Microsoft’s MOS 2016 Master credential page states that the Master qualification stopped being awarded after June 30, 2026 as the qualifying exam structure was discontinued. The safest interpretation is not to call 77-728 simply “retired.” Treat the individual exam page and the discontinued MOS 2016 Master qualification as separate facts, verify live scheduling before paying for preparation, and…

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 701-200 is the current version 2.0 exam for the LPI DevOps Tools Engineer certification. LPI released it after the version 1.0 exam ended in 2026, with updated emphasis on modern software development, CI/CD, GitOps, containers, automation, and operating reliable services. The ExamSnap LPI 701-200 page is the live exam destination. The certification sits between development and operations. Candidates are expected to understand how source code becomes a deployable artifact, how software is packaged for modern runtime environments, how infrastructure and configuration are automated, and how feedback from production affects…

LPI 701-100 was version 1.0 of the LPI DevOps Tools Engineer exam. LPI ended availability on June 30, 2026 and replaced it with version 2.0, LPI 701-200. The ExamSnap LPI 701-100 page should therefore be read as historical material, while the ExamSnap LPI 701-200 page is the current exam destination. The older exam remains useful for understanding the foundations of DevOps tooling: software engineering practices, containers, machine deployment, configuration management, and service operations. The mistake would be to treat its exact tool emphasis as the current blueprint, because version 2.0…

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 303-300 is the LPIC-3 Security exam, version 3.0. It tests the ability to administer and protect Linux systems across an enterprise, not simply to recall the names of security tools. The current LPI outline covers cryptography, host protection, access control, network security, and threats and vulnerability assessment. Candidates must hold an active LPIC-2 certification to receive LPIC-3 Security, so check that prerequisite as well as the exam objectives before booking. The ExamSnap LPI 303-300 page is a supplementary study destination, not a replacement for LPI’s own objectives. The breadth…
