Azure Fundamentals AZ-900: 45 Minutes for 50 Questions Needs a Different Order

Forty-five minutes is short. It is short enough that a candidate who reads every option carefully on every question runs out of time before question 40. The candidates who pass are not the ones who know more; they are the ones who triage.

The clock is the real constraint

Those are averages, and the exam is not a fixed 14/20/16 split. But they are a reasonable allocation to practise against, and they tell you where the time goes.

How to read the questions fast

Almost every AZ-900 item is a short scenario and a list of options where the distractors are things that sound Azure-ish but belong elsewhere. The triage is:

Read the requirement, not the scenario

The scenario is often two sentences of context you do not need. The requirement is a clause. Candidates who read the whole paragraph before starting to hunt for the answer lose thirty seconds per question. Find the clause that states what is required, then match it.

Match on the function, not the name

AZ-900 asks which service does a job. It does not ask you to configure one. "What service would you use to store unstructured files with tiered access?" is an Azure Storage question and you do not need to know whether it is Hot, Cool or Archive to answer it.

Use the elimination you already have

With three or four options, one is clearly not an Azure service at all, one is the wrong Azure service, and one is right. You only need real knowledge for the last comparison.

The three services that appear in nearly every version

Not the whole exam, but the recurring anchors that make Domain 2 feel manageable once you know them:

Domain 3 is heavier than it sounds

A third of the exam is management and governance, and it is the domain where non-technical candidates lose points, because the items are not about Azure at all — they are about what a governance tool does. Azure Policy for enforcement, management groups for organisational structure, Azure Monitor for telemetry, Cost Management for spend, and Microsoft Purview for data governance.

Note also that the AZ-900 blueprint explicitly names cost management, governance and compliance, and management and monitoring tools as assessed areas. Cost management appears in more than one form, and the Total Cost of Ownership calculator is the one specific artefact named in the objectives. That is a free mark if you know it exists.

Practising to the clock

Set a 45-minute timer on a full practice set. Not 45 minutes per domain. The whole thing. Most candidates who would pass with more time discover that they do not have it, which is exactly what you want to discover at home rather than at the testing centre.

The Azure Fundamentals certification page has the official objectives broken down, the AZ-900 question bank with explanations is weighted to the same three domains, and the difficulty breakdown shows where the question bank itself is hardest — which is not necessarily the domain with the most questions.
