Network+ · N10-009 Domain 1.4 · Subnetting & IP Foundational

A company is allocated 192.168.10.0/26 for a small department. How many usable host addresses are in this subnet?

Pick an answer. The explanation is instant.
Correct.

Why B is correct

A /26 leaves 6 host bits, so 2⁶ = 64 addresses. Drop the network and broadcast addresses and 62 are usable for hosts.

What you'll actually use

One adaptive question engine, the same across every cert we cover.

The engine · adaptive
AI questions that adapt to you

Every session generates fresh questions across the full blueprint, each with an explanation that teaches the reasoning behind the right answer. The more you practise, the harder it leans on your weak spots.

In every workspace
Readiness score

One number tracks your coverage and accuracy across the blueprint. When it reads green, you book.

Full Exam Simulator Pro

A 90-question, 90-minute exam scored 100-900, built to mirror the real exam-day sitting.

Weak-spots + spaced repetition

Your weak objectives resurface on a spaced-repetition schedule until they hold.

The Pro drills

The exam has two tricks. Now you have two drills.

Real exams beat question-bank grinders two ways: they re-word everything you practised, and they make every wrong answer look right. One drill trains each.

Built from how people actually fail: the wording flips, and the look-alike options.

See Pro plans → Both drills are Pro, and run on every cert in the library. Start free with the baseline diagnostic; Pro drills unlock at launch.
Why CertAnvil

Walk in knowing.Not hoping.

Most people book the exam on a gut feeling. CertAnvil tracks every objective on the blueprint until it's closed, then gives you one honest readiness score. You sit the test when it reads green, not when nerves say maybe.

Built by someone who sat N10-009 and passed at 767/900, then built the prep they wish they'd had.

No guesswork. The blueprint, closed.
How it's built

Why it holds up under a real exam.

Four things most prep tools skip. Each one is why a high score here means you're ready for the exam room, not just good at one question bank.

01
Mapped to the real exam blueprint

Every question maps to a published objective on the exam blueprint, weighted the way the real test weights them. You study what the exam covers, not what a generic study app guesses you'll need.

02
You'll never see the same question twice

Most tools recycle one fixed bank, where a high score can just mean you memorised the answers. CertAnvil writes fresh questions every session. To score well, you have to know the material.

03
Questions get checked before you see them

AI alone makes mistakes. Every question clears seven checks first, including a second AI pass and a factual-correctness gate. Wrong answers never ship.

04
Know when you're ready

Feeling ready and being ready are different things. Your readiness score is one number, recalculated after every quiz and weighted to the exam blueprint. When it turns green, book the exam.

And the same engine sits behind every cert. Eight certs live today, with more on the anvil.

How is this different from other cert prep tools?

Most cert prep is a fixed bank someone wrote years ago. You churn through it, memorise the answers, and end up confident on the bank but shaky on the exam. CertAnvil writes fresh questions every time you study, so you can't shortcut it.

A static bank isn't a bad thing. Some people prefer working a fixed set linearly, and plenty of our users keep one for breadth and use CertAnvil to drill the weak spots. Whatever works for how you study.

Can I really study for free?

Yes, properly free, not a 7-day trial. You get 15 fresh AI-generated questions, 5 spaced-review cards, and 1 Reword Gauntlet run every day (the Gauntlet sits on top of the 15, it never spends them), plus the diagnostic, your Pass Plan, your streak tracker, and your analytics. Enough to keep a real daily habit going.

Unlimited questions, unlimited Reword Gauntlet, the Why-Not drill, the Full Exam Simulator, and advanced analytics are Pro. When 15 a day stops being enough, or you want unlimited drilling and full timed mock exams, that's when most people upgrade.

What's the difference between Free and Pro?

Two tiers, both paid for forever. No annual nonsense, no hidden quotas inside Pro.

Pro is $9.99/mo or $89/yr (saves ~26%) and covers every cert in the lineup, not just one.

What's a Performance-Based Question (PBQ)?

PBQs are the hands-on parts of the exam: configuring a topology, typing CLI commands, sorting items into the right place. They're worth roughly 40% of your score. They're the next thing we're building, a CLI sim, a topology builder, and an ACL builder, all landing in Pro. For now, the question engine and its explanations cover the concepts each PBQ tests.

How do I know when I'm actually ready for the exam?

Your readiness score tracks coverage and accuracy across every exam objective, including a full timed mock exam. When it reads green you've shown consistent mastery of the whole blueprint. That's your signal to book, instead of guessing. If Pro isn't right for you, there's a 14-day money-back guarantee.

Do I need my own AI key or anything?

Nope. The AI cost is on us, Free and Pro both. You don't need to set anything up, paste any keys, or know what an API is. Just sign up and study.

What if my exam isn't on the list?

Hit "Notify me" on the cert tile and we'll email you the day it goes live: no marketing list, just that one email. Network+ and Security+ are live now; AZ-900, CCNA, AWS SAA, and AZ-104 are next in the queue.

Can I cancel anytime?

Yes, from your account in two clicks. Monthly plans stop at the end of the current month; annual plans stop renewing but you keep Pro for the rest of the year you paid for. No cancellation form, no "are you sure" nonsense.

How do you keep the questions original?

Every question is generated from scratch, then put through seven separate checks before you see it. The reference set the AI learns from is 320+ exemplars we wrote ourselves from the public exam blueprint. We don't train on or scrape questions from any paid prep company. It's clean, original, and tied directly to the exam objectives.
