Take the courses for the theory, then switch to measurement: the MS-101 practice questions from TestKingsIT — with auto-graded mock tests — show you what is actually sticking.

You're looking at 40–60 questions in 120 minutes. Do the math early, not in the exam room: decide your per-question pace, practice skipping hard items without panic, and finish at least two full timed mock tests — the TestKingsIT engine grades them automatically in about a minute, so you get instant feedback on where your time goes.

Delivery is the easy part: pay, click the email link that arrives within a minute, and the MS-101 files download in about a minute — no extra software, no installation limits. If 2 hours pass with nothing, our support team will fix it. The refund side runs on clear rules: take the corresponding MS-101 exam within 60 days of purchase, and if you fail, submit a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam for a 100% refund, processed within 7 days. Exams sat within 3 days of purchase don't qualify, candidate and payer names must match, and free or expired products are excluded. Prefer an exchange? Take two equal-value exam products free of charge and keep your original updates.

You need 700 / 1000 to pass, and registration costs $165 USD at the official rate. One uncomfortable truth: the fee is per attempt, so a fail means paying it again. Candidates who self-test first — with auto-graded mock exams built from the 408 questions at TestKingsIT — tend to pay that fee exactly once.

The vendor's blueprint for the Microsoft 365 Mobility and Security has 3 domains, led by Manage security and threats by using Microsoft 365 Defender (25–30%), Manage Microsoft 365 compliance (30–35%), Plan and implement device services (35–40%). The weighting is a study plan in disguise — heavy domains deserve heavy hours. You'll find every domain and subtopic in the complete outline above.

Passing the MS-101 exam earns the Microsoft 365 Certified: Enterprise Administrator Expert certification — a Expert-level credential — issued directly by Microsoft. It is proof of ability that travels well across employers and borders. The credential also links to MS-100 Microsoft 365 Identity and Services, so it can be a first step rather than a final destination.

Yes — the free PDF demo shows the real question quality before any payment. And the value continues after purchase: 365 days of free updates come standard, with a 50% renewal discount if your update period ever expires.

Requires passing MS-100; plus one Microsoft 365 workload certification or MCSE: Productivity to earn Expert certification These rules do get revised, so before you book, double-check the current requirements on the official MS-101 exam page — what the vendor publishes is what counts.
