Am I Ready for AZ-104? A Practical Readiness Checklist

The scariest moment in an AZ-104 journey is not the exam itself. It is the day before you book it, staring at the schedule button and wondering whether you are actually ready or just tired of studying. Those are very different things, and confusing them is how people either waste an exam fee or postpone forever.

This post is not about how hard AZ-104 is (we cover that separately) or about generic exam-readiness advice. It is the concrete, AZ-104-specific checklist: the measurable signals that tell you it is time to book the Azure Administrator exam, and a clear go / not-yet decision framework so you are not relying on a gut feeling.

Why 'I feel confident' is the wrong test for AZ-104

AZ-104 is graded on a scaled score of 700 out of 1000, not a raw percentage. That means the exam already accounts for question difficulty and domain weighting, so a comfortable feeling on easy topics does not offset weakness on the heavy ones. You need evidence that you are consistently strong where the exam actually spends its points, which is compute and networking.

The format compounds this. You get roughly 40 to 60 questions in about 100 to 120 minutes, and the mix can include multiple-response items, drag-and-drop, hotspot, and one or more case studies. Feeling confident on single-answer multiple choice tells you almost nothing about how you will handle a 'select all that apply' NSG question under a ticking clock. Readiness has to be tested in the same shape as the exam.

Signal 1: Your practice scores are consistent, not a single lucky run

One good practice score proves almost nothing. Question sets vary, and any single session can land on your strong topics by chance. What you are looking for is a stable pattern across several independent attempts, not a personal best you screenshot and never repeat.

A practical bar: your last three to four measured practice sessions (each a real block of 20 or more questions, not a five-question warm-up) should all sit comfortably above passing, with a small spread between your best and worst. If your scores swing from 62 to 88 percent depending on the day, you are not ready, you are volatile. Volatility usually means one or two domains are dragging you down and getting masked by strong domains on your good days.

• Ready signal: three or more recent sessions clustered above your target, low variance, and you can explain why the wrong answers were wrong without looking.
• Not-yet signal: one great score surrounded by mediocre ones, or a wide gap between attempts that depends on which topics happened to appear.
• Trap to avoid: retaking the same small question set until you have memorized it. That measures recall of those items, not readiness for new ones.

This is exactly the gap between a readiness estimate and a single average score, and it is worth understanding the distinction before you trust any number. A tool that blends your recent measured attempts into a single estimate is more honest than the high-water mark you remember.

Signal 2: You are ready domain by domain, especially networking and compute

AZ-104 covers five skill areas: identity and governance, storage, compute, networking, and monitoring. An overall practice average can hide a fatal weakness, because a strong identity and storage performance can carry a shaky networking score right up to a passing-looking total. On exam day, the weighting will not be so kind to you.

Networking and compute are the heaviest and hardest domains for most candidates, so treat them as gatekeepers. You should not book until you are individually solid in both, not merely surviving them on the strength of your easier domains. Look at your results per domain, not just the headline number.

• Networking: you can predict how an NSG evaluates rules by priority, reason about subnet-level versus NIC-level rules, choose between Azure Load Balancer and Application Gateway for a scenario, and explain VNet peering and private DNS behavior.
• Compute: you can distinguish availability sets, availability zones, and scale sets, read an ARM or Bicep snippet and predict what it deploys, and reason about autoscale rule logic.
• Identity, storage, monitoring: no single domain should be sitting well below passing, because the exam can draw more from a weak area than your average assumes.

Signal 3: You can do the labs, not just recognize the answers

AZ-104 rewards hands-on muscle memory. The single most common reason capable people fail is studying passively: watching a course or reading explanations until the correct answer looks familiar, without ever doing the task themselves. Recognition is not the same as ability, and the exam's scenario questions are designed to catch the difference.

The honest test is simple. Pick a task and do it in the portal from a blank start with no walkthrough open. If you can complete the core AZ-104 tasks unaided, you have real readiness. If you need to peek at a guide, that topic is not ready yet, however good it looks on a multiple-choice question.

• Create two VNets, peer them, and verify connectivity, then lock traffic down with an NSG and confirm a blocked port is genuinely blocked.
• Deploy a Virtual Machine Scale Set with a CPU-based autoscale rule and watch it scale, and deploy the same VM from an ARM or Bicep template.
• Assign RBAC roles at management group, subscription, resource group, and resource scope, and observe inheritance.
• Create a storage account, generate a SAS token, then restrict it with a firewall rule and a private endpoint.
• Stand up a Recovery Services vault, back up a VM, and perform a restore, and configure a metric alert with an action group.

If you can walk through that list without help, your practice scores mean far more, because they are backed by ability rather than pattern-matching. If you cannot, no practice percentage should convince you that you are ready.

Signal 4: You have passed a full-length, timed mock under real conditions

Short drills build knowledge, but they do not test stamina, pacing, or how you behave when a hard question eats four minutes. The real exam is a sustained 100-to-120-minute effort, and plenty of well-prepared candidates lose points late simply because they never rehearsed the endurance of it.

Before you book, complete at least one full-length timed mock in one sitting, in exam-style format, and pass it comfortably. Do it without pausing, without looking anything up, and without your notes open. A timed mock that mirrors the real exam's style is the closest rehearsal you can get, and it surfaces problems a quiz never will.

• Pacing: you finish with a sensible time buffer, rather than either racing or running out of clock.
• Focus: your accuracy in the final third holds up and does not collapse from fatigue.
• Recovery: when a question stumps you, you flag it and move on instead of burning ten minutes and derailing your rhythm.

If your timed full-length result is well above passing and your pacing held, that is one of the strongest single signals on this list. If you have only ever done untimed practice in small chunks, you have not yet tested the thing the exam actually measures.

Signal 5: You read multi-response and case-study questions cleanly

A surprising share of AZ-104 losses are reading errors, not knowledge gaps. Multiple-response questions ('select two', 'select all that apply') punish a right idea paired with one extra wrong pick, and case studies bury the decisive detail in a wall of background text. You can know the material and still bleed points if you process these formats poorly.

• On multiple-response items, you identify exactly how many answers are required and resist adding a plausible-but-wrong extra, because a single wrong selection can cost the whole question.
• On case studies, you read the scenario tabs first, extract the constraints that actually drive the answer, and remember you generally cannot return to a case study once you leave it.
• On any long stem, you spot the qualifier ('least privilege', 'lowest cost', 'least administrative effort', 'highest availability') that separates the technically-correct answer from the best answer.

Readiness here means you have practiced enough of these formats that they feel routine. If drag-and-drop, hotspot, and case-study questions still feel unfamiliar, spend a few sessions specifically on those before you book, so the format never surprises you on the day.

The go / not-yet decision framework

Put the signals together into a single decision. You do not need every box perfect, but the non-negotiables are the heavy domains and a passing timed mock. Book AZ-104 when all of the following are true.

1. Your last three or four measured practice sessions (20 or more questions each) are consistently and comfortably above passing, with low variance.
2. No individual domain is below passing, and networking and compute in particular are solidly above it, not merely scraping by.
3. You can complete the core hands-on lab tasks in the portal from scratch without a walkthrough.
4. You have passed at least one full-length timed mock in a single exam-style sitting, with your pacing and accuracy holding to the end.
5. Multiple-response, drag-and-drop, hotspot, and case-study formats feel routine rather than unfamiliar.

If all five are true, stop studying to feel safer and book the exam, ideally within a week or two so your peak does not go stale. Waiting longer once you are genuinely ready tends to add anxiety, not points.

If you are not ready yet, do this

A not-yet verdict is useful, because it tells you exactly where to aim. Do not restart your whole study plan. Target the specific gap the checklist exposed and re-test the same signal.

1. Find your weakest domain from your per-domain results and drill it directly, rather than re-reviewing topics you already score well on.
2. For every wrong answer, do the matching lab task by hand until you can do it unaided, so the fix sticks as ability, not recognition.
3. Rebuild consistency: take fresh measured sessions on new questions until three in a row clear passing, instead of retaking a set you have memorized.
4. Once your domains are level, do one more full-length timed mock and confirm your pacing holds to the end.
5. Then re-run the go / not-yet framework. When the five boxes are green, book with confidence.

CertGrid is built to make these signals visible. It scores you domain by domain against the exam blueprint and blends your recent measured attempts into a single readiness estimate, weak-domain drills let you target a low area like networking, and timed mock exams rehearse the real exam's style and pacing. The free plan lets you practice a fixed sample question pool for each exam to try the format, and full timed exams, the full AZ-104 question bank, full explanations, and domain analytics come with a Single Exam Pass (six months) or Pro. Note that these are original practice items for study, not official, real, or leaked exam questions, and no tool can guarantee a pass, but honest signals beat a hopeful guess every time.

Bottom line

You are ready for AZ-104 when the evidence says so, not when you are simply worn out from studying. Consistent scores across several real sessions, solid per-domain strength in networking and compute, hands-on lab ability, a passing full-length timed mock, and clean handling of the tricky question formats: hit all five and book without second-guessing. Fall short on a non-negotiable and you now know precisely what to fix. Either way, you are deciding on data instead of nerves.
