Free AND-402: Android Security Essentials Exam Questions and Answers
Android Security Essentials is exam AND-402, part of Android ATC's certification programme. Android ATC is a private training company in Ontario, and its own about page states plainly that it is independent and not affiliated with Google — worth knowing, because the credential names invite the opposite assumption. It writes its own AND- codes, its own syllabus and its own exams, and names no independent accreditation anywhere on its site. The exams themselves are uniform: 45 questions in 90 minutes, 70% to pass, $150, online proctored. They do not expire, but each is tied to the Android version it was written against, which dates them in practice.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
