Locked In: Prep for Cloud+

CV0-004 study companion

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

All 6 CV0-004 domains in bite-sized lessons, with diagrams for service models, IaC, containers, IAM, and CI/CD, plus scenario PBQs and a full timed mock exam. Locked-In is a bite-sized study companion for the CompTIA Cloud+ (CV0-004) 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 6 CV0-004 exam domains, broken into bite-sized lessons • Visual diagrams for every key cloud concept (service and deployment models, shared responsibility, HA design, IaC, containers, autoscaling, IAM, encryption, CI/CD pipelines, GitOps, and more) • Inline quick-checks at the end of each lesson • A practice bank of 324 multiple-choice questions, organized by domain and difficulty • Scenario-based questions (PBQs) — drag-and-drop categorize, ordering, and matching • A full 60-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 Cloud+ alongside a day job • Students supplementing a course or boot camp • IT and ops staff moving toward cloud 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 CV0-004 objectives THE 6 DOMAINS 1.
