Most candidates prepare thoroughly for the questions and not at all for the exam. Then they sit down, discover the proctor wants the desk cleared and a 360-degree camera sweep of the room, and spend the first ten minutes rattled rather than reading question one. None of that is difficult - it is just unfamiliar, and unfamiliar costs you marks.
This is what the process actually looks like, what varies by vendor, and where it is worth booking a test centre instead. It is deliberately about the logistics rather than the content: for the content side, start with how to know you are ready.
Before you book: check the delivery options
Almost every major certification offers both online proctoring and a physical test centre, and the exam is identical either way. What differs is the environment you have to produce. Online means you supply a compliant room, a working machine and a stable connection; a test centre means someone else has already solved all three.
A handful of exams are not multiple choice at all, and that changes the calculation. A performance-based exam like CKA puts you in a live cluster with a terminal for two hours, so connection stability matters far more than it does on a standard question paper. If your home connection drops occasionally, that is the exam to sit in a test centre.
- Online proctored - cheaper in time, no travel, and you can usually book a slot within days. You own every technical risk.
- Test centre - fixed hardware, wired connection, an invigilator in the room, and no room scan. Fewer slots, and you have to travel.
- Either way the score, the passing mark and the question pool are the same. Choosing a test centre is not an easier exam.
The system check happens before exam day, and you should do it twice
Every online proctoring platform ships a pre-exam system test: it checks your camera, microphone, speakers, browser and bandwidth, and it usually installs a locked-down browser or a small client application. Run it as soon as you book, and run it again the day before on the actual machine, in the actual room, on the actual network you will use.
The reason for twice is that the failures are environmental rather than technical. A work laptop with a managed security agent, a VPN that reconnects automatically, a corporate firewall, a second monitor, a virtual camera left behind by a conferencing app - all of these pass a casual check and fail on the day. If you are sitting the exam on a work machine, assume it will be the problem until you have proved otherwise.
- Use a wired connection if you have one, and turn off anything that auto-updates or auto-reconnects.
- Disconnect second monitors physically, not just in display settings. Most platforms refuse to start with two displays attached.
- Close everything, including the things that live in the tray. The lockdown client will list what it wants killed, and it will not start until you comply.
- Know where your machine's camera and microphone permissions live, because you will be asked to grant them under time pressure.
Check-in: ID, room scan, and the desk
Check-in typically opens fifteen to thirty minutes before your slot, and it is worth using all of it. You will be asked for government-issued photo identification, held up to the camera, and the name on it has to match the name on your certification profile exactly. A middle name on one and not the other is the single most common reason a candidate is turned away, and it cannot be fixed on the day.
Then comes the room scan: you pick up the laptop or webcam and show the proctor the whole room, including under the desk and the walls behind you. This is the part people find intrusive and it is the part that goes fastest if the room is already clear. What they are looking for is other people, other screens, paper, and anything on the walls that could be notes.
- Photo ID whose name matches your certification profile character for character.
- A clear desk. No paper, no phone, no notebooks, no second keyboard, no smart watch.
- A room with a door you can close, and no one else in it for the duration.
- Water in a clear container is usually permitted; food usually is not. Check your confirmation.
- Physical whiteboards and scratch paper are generally not allowed online, which is a real difference from a test centre. Most platforms provide an on-screen notepad instead - find it during the tutorial, not during question forty.
What gets you flagged
Proctoring is part software, part human. The software watches for faces leaving frame, additional faces, audio, and window focus changes; a human reviews what it raises. Almost nobody is failed for cheating - people are failed for behaviour that looks like it, which is avoidable if you know what it is.
- Reading questions aloud, or muttering while you think. Very common, and it looks exactly like talking to someone.
- Looking away from the screen for long stretches. Thinking with your eyes on the ceiling is normal behaviour and abnormal exam behaviour.
- Anyone entering the room, including briefly. Lock the door and tell the household.
- Leaving the frame. Most exams have no scheduled break, and standing up without permission ends some sessions.
- A phone that rings, even face down and silent-but-vibrating on the desk. Put it in another room.
When the software fails mid-exam
It happens, and the important thing is that it is usually recoverable. Sessions are generally saved server-side rather than locally, so a dropped connection or a client crash typically drops you back into the same attempt at the same question once you reconnect. Do not close anything, do not restart the machine on instinct, and do not start a fresh attempt.
- Stay at the desk and in frame. Walking away during an interruption looks worse than the interruption.
- Use the platform's chat or support option if it is still responsive - that is the record that the failure happened.
- If the client has closed entirely, relaunch it and sign back in with the same booking. Most platforms will resume.
- If you cannot resume, raise a case with the certification vendor the same day, while the provider's logs still show the session. A same-day case is treated very differently from one opened a week later.
Formats differ more than the process does
The proctoring experience is broadly the same everywhere. What changes is what you are being asked to do inside it, and that is worth rehearsing beforehand rather than meeting cold.
- Standard multiple choice and multiple response - AZ-900, DP-900 and AWS CLF-C02 are the cleanest examples, and the least to go wrong.
- Multiple choice plus interactive item types - Microsoft role-based exams such as AZ-104 and PL-300 mix in drag-and-drop, ordering and case studies. Practise the mechanics, not just the content.
- Performance-based questions inside a question paper - Security+ SY0-701 opens with PBQs that take longer than they look. Leaving them for the end is a common and expensive habit.
- Simulations and configuration - CCNA 200-301 includes items where you configure rather than choose, and you cannot go back to a completed section.
- A live environment for the whole exam - CKA is a terminal and a real cluster. Speed with the tooling is a scored skill.
- Long adaptive-feeling papers - CISSP and AWS SAA-C03 are endurance events as much as knowledge tests, and fatigue is what actually ends most attempts.
If you are not sure which of these you are walking into, the certification roadmap shows how the tracks fit together, and each exam page lists the real format alongside the practice pool.
A short exam-day checklist
- Run the system check again on the real machine, in the real room, the day before.
- Clear the desk and the walls. Move the phone to another room.
- Photo ID out, name matching your profile exactly.
- Close the door, tell the household, and check in at the earliest permitted time.
- Read the tutorial screens instead of skipping them - that is where the on-screen notepad and the review flags are.
- Flag and move on rather than stalling. Time lost early is not recoverable late.
None of this substitutes for knowing the material. It just stops the twenty minutes around the exam from costing you the exam - which, for a surprising share of failed first attempts, is what happened.
