Choosing who maintains an application's operating system is one of the first cloud decisions. Cloud computing supplies processing power, storage, networking, and other computing services without requiring every customer to operate the underlying datacenter. The service selected determines which jobs remain with the customer.
Microsoft Azure Fundamentals, assessed by exam AZ-900, focuses on understanding these choices at a foundational level. It connects general cloud concepts with Azure architecture and services, then considers how resources are managed and governed. This knowledge helps a learner distinguish a suitable service from one that solves a different problem, even before learning detailed deployment procedures.
The division of operating responsibility is central to the three cloud service models.
| Service model | What the customer receives | Typical customer responsibility |
|---|---|---|
| Infrastructure as a service (IaaS) | Virtual infrastructure, such as Azure Virtual Machines | Manage the guest operating system and application software, including patching. |
| Platform as a service (PaaS) | An application platform with a provider-managed operating system and runtime for executing code | Deploy and maintain application code and configure the application appropriately. |
| Software as a service (SaaS) | A finished, provider-operated application | Manage users, access decisions, data, and the settings under customer control. |
More control brings more maintenance. A custom operating-system requirement may favor IaaS, while a team that only needs to deploy application code may prefer PaaS. Across these models, moving infrastructure work to a provider does not remove the customer's responsibility for its data and identities.
Public, private, and hybrid cloud describe deployment models rather than the same responsibility split. A public cloud offers services to multiple customers through a provider. A private cloud is reserved for one organization, and a hybrid cloud connects private and public environments. A workload can therefore combine a hybrid deployment with several service models. Calling a workload hybrid does not establish who patches each operating system.
Capacity and availability also need different reasoning. Horizontal scaling changes the number of instances, adding or removing them. Vertical scaling changes an individual instance's capacity, increasing or decreasing it. High availability concerns keeping a service usable despite disruptions. Adding more instances can meet rising demand, but their placement and configuration still determine how they respond to a failure.
These choices also affect cost. Consumption-based pricing links charges to measured use rather than promising an identical monthly bill. Increasing compute capacity or retaining associated storage changes what is consumed, so a service choice needs both an operating model and realistic usage assumptions. Cloud capacity can be reduced when demand falls, but unused resources must actually be released or reduced to change the relevant charges.
For AZ-900 study, explaining why an answer fits the stated requirement is more useful than remembering a product name in isolation. Read-only access, configuration compliance, and protection from accidental deletion are different requirements, even when they concern the same resource. Answering short questions can reveal misunderstandings about those distinctions, but it does not establish the ability to deploy or secure a production environment. Foundational preparation also needs the full exam objectives and hands-on learning.
How to Use This Tool:
This unofficial practice uses independently authored questions and is not affiliated with or endorsed by Microsoft. A fresh setup starts with five mixed-domain questions and feedback after each answer. Practice is untimed, so choose immediate explanations for learning or delayed corrections for an uninterrupted attempt.
- Choose Domain / practice focus and Question count. All domains offers 2, 5, 10, 20, or 36 questions and defaults to five. Focused domains offer smaller menus up to their full pool. Changing focus resets an unavailable count to five.
- Choose Feedback timing. Learn — feedback after each answer reveals the correction and explanation immediately. Review — feedback at completion records the answer without revealing whether it is correct until you view the completed results.
- Enter an optional Replay seed under Advanced when you need repeatable questions and option order. Leaving it blank uses a stable default, not a fresh random draw. Spaces at the beginning and end are ignored. Reproducibility requires the same practice content, focus, count, feedback mode, and seed.
The seed is limited to 128 UTF-16 units; many emoji use two units. Long entries are shortened to the limit. If seed validation prevents starting, replace the entry with a short label using ordinary letters and numbers.
- Select Start exam practice and answer each question by choosing one of four options. Selecting an option submits and locks it immediately; there is no separate confirmation or opportunity to change that answer. Use Next question to continue.
End round clears the attempt and returns to setup. It does not submit an unfinished round for a final score.
- Select View results after answering every question. Check the correct-answer total, Missed answer review when present, and the explanations and source links in the Answer ledger.
If Domain performance cannot load its chart, use Retry chart. The written domain counts and answer ledger still provide the review information.
- Choose a follow-up round. Retry missed starts a new attempt containing only the missed questions. Replay same seed repeats the completed round's questions and option order. Try a new seed requests another seeded round, but familiar questions can recur. Select Change setup to choose a different focus or round length.
Interpreting Results:
During a round, the headline and progress bar describe how many questions you have answered, not how many you have answered correctly. After completion, the headline changes to the number correct out of the total. Perfect round means that none of these selected questions was missed. It is not an exam-readiness rating.
Domain performance shows counts of correct and missed answers, not a percentage score for each domain. A larger bar may simply mean that more questions came from that domain. A domain marked Not sampled in this round, or absent from the chart, has not been tested. Use the specific mistakes and their explanations to choose further study rather than treating a short mixed round as a balanced assessment.
The Answer ledger records the selected answer, the authored correct answer, and the explanation for every question. Compare the reasoning with the linked documentation, especially when two services have similar names. Repeated success on familiar questions can reflect recognition rather than the ability to solve an unfamiliar scenario.
Microsoft reports technical exam results on a scale of 1 to 1,000 and requires at least 700 to pass AZ-900. A scaled score of 700 is not equivalent to answering 70% of these practice questions correctly. No practice percentage here converts to a Microsoft score, pass prediction, certification, or proof of professional competence.
Technical Details:
A raw practice score measures agreement with an authored answer key across a selected group of questions. Its meaning depends on which questions were included and how they were scored. Domain weights, difficulty calibration, and demonstrated practical skills cannot be inferred from that count.
Scoring each answer state
Every question contributes one possible point. Accuracy divides correct answers by all questions in the round, while progress divides recorded answers by that same total.
Here, C is the correct-answer count, A is the answered-question count, and N is the positive total number of questions in the round. All three are whole-number counts. The point total equals C, the maximum possible points equal N, and accuracy ranges from 0% to 100%. There is no partial credit, negative marking, or extra weighting for a particular domain.
| Answer state | Points | Counts as answered | Counts as missed |
|---|---|---|---|
| Correct selection | 1 | Yes | No |
| Incorrect selection | 0 | Yes | Yes |
| Not answered | 0 | No | No |
Completion requires an answer to every question. Unanswered questions remain in the accuracy denominator without becoming incorrect answers. For example, one correct answer in a two-question round gives 50% calculated accuracy and 50% progress, with no misses yet. The final review is not available until the second question is answered. Raw accuracy and underlying progress are unrounded. Visible progress text rounds to the nearest whole percent, with half-percent ties upward; the bar width and accessible progress value retain the raw percentage. Correct-answer totals and domain counts remain exact.
Exam scope and question sampling
The practice content targets the English AZ-900 skills measured as of July 20, 2026. The skills-measured date identifies an objective edition, not an exam launch date or exact live question composition. The independently authored bank is dated September 11, 2026 and contains 36 English single-choice questions. The official percentages below describe exam emphasis, while the question counts describe this smaller practice bank.
| Domain | Official share | Practice questions | Selected practice topics |
|---|---|---|---|
| Cloud concepts | 25% to 30% | 10 | Shared responsibility, deployment and service models, consumption, scaling, and serverless concepts |
| Azure architecture and services | 35% to 40% | 14 | Resource organization, availability zones, compute, networking, storage, and identity |
| Azure management and governance | 30% to 35% | 12 | Cost estimates and budgets, tags, policy, locks, deployment, governance, and monitoring |
Questions are sampled uniformly without replacement from the chosen set. A question cannot appear twice within one round, but the selection does not enforce the official domain percentages. Short mixed rounds can omit a domain entirely. The seed controls the repeatable question selection and option order, and different seeds can select overlapping questions.
Completing all 36 questions exhausts this bank, not the official objectives. Storage tiers, Azure Migrate, and Microsoft Defender for Cloud are examples of topics that require additional study. The questions include concepts and short scenarios, but their difficulty has not been calibrated to Microsoft's exam. The official proctored assessment allows 45 minutes and may include interactive components; untimed four-option practice does not reproduce that experience. Localized exam editions may update after the English edition, so check the outline relevant to the language and date of your exam.
Resource organization, permissions, and protection
Azure management scopes explain how widely a rule or permission applies. Management groups organize subscriptions, subscriptions contain resource groups, and resource groups organize related resources. Assignments such as roles and policies can apply to resources beneath the selected scope. This management hierarchy does not create physical separation between workloads.
Availability zones concern physical fault isolation within a region. A zone-redundant deployment distributes supported resources across zones, whereas putting resources into different resource groups does not protect them from a zone failure. Support depends on the service, region, and configuration. Protection against a zone failure is also not protection against the loss of the entire region.
For access questions, Azure role-based access control (Azure RBAC) combines a principal, such as a user or group, a role defining permitted actions, and a scope. Configuration rules and deletion protection address different requirements.
| Requirement | Relevant mechanism | Important boundary |
|---|---|---|
| View resources in one resource group | Assign the Azure RBAC Reader role at that scope. | The role grants read-only management access. It does not cancel broader permissions from other role assignments. |
| Audit configuration or deny a noncompliant deployment | Assign an appropriate Azure Policy definition. | The definition, effect, supported resource properties, and assignment scope determine what is evaluated or blocked. |
| Prevent accidental deletion while permitting authorized updates | Apply a CanNotDelete resource lock. |
Locks restrict resource-management requests, called control-plane operations, not all operations on stored data. A ReadOnly lock also restricts modifications. |
Privacy and Saved Attempts:
Answers are scored in your browser, but the attempt is not private merely because scoring is local. The address carries enough information to restore the round, including its seed and recorded choices, without encryption. Anyone receiving that link can reopen those choices. The URL can remain in browser history and reach the site when opened or reloaded. Do not include credentials or personal information in a replay seed, and share attempt links or exported answer ledgers only intentionally.
Page loading, chart and document support files, and opened reference links can use the network. Local scoring therefore does not establish fully offline operation or a guarantee that nothing leaves the device.
A saved attempt must remain compatible with the current practice content. If Saved attempt unavailable appears for an invalid or outdated link, start a new round. If a warning says the attempt could not be saved to the URL, the answers remain on the current page, but reloading will lose that attempt. Returning to setup starts over rather than repairing the saved link.
Worked Examples:
One missed budget question
Suppose a five-question Azure management and governance round includes the spending-notification question. Selecting A resource deletion lock is incorrect; the authored answer is Cost Management budget alerts. With the other four answers correct, the completed headline is 4/5, equivalent to 80% accuracy, and the domain result contains four correct answers and one miss. Retry missed creates a one-question round even though the ordinary setup menu starts at two. The correction matters beyond the score: a budget alert sends a notification, but it does not by itself cap spending or stop resources.
A perfect architecture round
Select all 14 Azure architecture and services questions and answer every one correctly. The result is 14/14 and Perfect round, while the cloud-concepts and management-and-governance domains were not sampled. A new seed cannot supply unseen architecture questions after this full-domain round because the pool still contains the same 14 items; it can change their ordering and the option order. Switch to another focus or study objectives outside the bank rather than interpreting this result as complete AZ-900 preparation.
