Features & Capabilities

All 5 N10-009 domains in bite-sized lessons, with diagrams for OSI, subnetting, VLANs, routing, and Wi-Fi, plus PBQs and a full timed mock exam.

Locked-In is a bite-sized study companion for the Network+ (N10-009) exam. Built for people who study in 10-minute windows — on the train, on lunch, or between calls. Every lesson is short, focused, and ends with a quick-check so you know what stuck.

WHAT'S INSIDE • All 5 N10-009 exam domains, broken into bite-sized lessons • Visual diagrams for every key networking concept (OSI, subnetting, VLANs, STP, OSPF, DHCP, DNS, NAT, wireless topologies, PoE classes, and more) • Inline quick-checks at the end of each lesson • A practice bank of 90+ multiple-choice questions, organized by domain and difficulty • Performance-based questions (PBQs) — drag-and-drop categorize, ordering, and matching • A full 90-question, 90-minute timed mock exam with flag-for-review and a final review screen • Flashcard deck of must-know terms with SM-2 spaced repetition • Searchable glossary covering every acronym you'll see on test day • Progress tracking, streaks, bookmarks, and personal notes • Weak-spot review that surfaces the topics you keep missing

WHO IT'S FOR • Career changers studying Network+ alongside a day job • Students supplementing a course or boot camp • Help-desk and ops staff moving toward networking roles • Anyone who learns better in short, focused sessions than long lectures

WHY LOCKED-IN • Works fully offline — no account, no tracking, no ads • One-time unlock, no subscription • Built by an indie developer, not a content mill • Content aligned with the current N10-009 objectives
