Locked In: Prep for Cloud+

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
