Are these real AZ-900 exam questions?

No — and you should be wary of any site that says its questions are. Real exam items are confidential. These questions are written from scratch against the published AZ-900 exam guide to match its style, difficulty and domain weighting.

Should I use AZ-900 dumps?

No. A dump is a collection of leaked or memorised real exam items, and using one breaks the Microsoft Azure certification agreement — the vendor can revoke your certification and ban you from future exams. Dumps also tend to fail on their own terms: their answer keys are unverified, they drift out of date as the exam changes, and memorising answers leaves you stuck the moment a question is reworded. Original practice questions with an explanation on every option teach the reasoning the AZ-900 actually tests, which is what carries over to questions you have never seen.

Do the AZ-900 questions come with explanations?

Every option carries its own explanation — not just the correct one. You find out why the answer you nearly picked was wrong, which is where most of the learning actually happens. Each question also links back to the revision lesson that teaches the concept.

How many practice questions should I do before the AZ-900 exam?

Volume matters less than what you do with the misses. A useful signal is consistency rather than a total: when you can hold a comfortable margin above the 700 pass mark on questions you have never seen before, across every domain rather than just your strong ones, you are ready.

Can I retry the questions I got wrong?

Yes. Wrong answers and flagged questions go into a review pool you can drill on their own, so you can grind exactly the material that is costing you marks instead of re-answering the ones you already know.

Question 1Describe cloud concepts

Which statement best defines cloud computing?

Choose one.

a
Running computing workloads on servers your own IT team buys, houses, and maintains
This is a traditional on-premises datacenter: you buy and own the hardware up front, which is what cloud computing replaces.
b
Renting compute, storage, and networking over the internet and paying for what you use Correct
Cloud computing is the delivery of computing services over the internet, rented on demand and billed for what you consume.
c
Leasing dedicated servers on a multi-year contract that is billed whether used or not
A fixed multi-year lease charges for capacity regardless of use, so it lacks the on-demand, pay-for-use character of cloud computing.
d
Sharing computing resources between branch offices over a private wide area network
A private WAN only connects your own sites; it does not deliver rentable compute, storage, and networking services from a provider.

The concept

Cloud computing is the on-demand delivery of computing services over the internet, paid for as you use them.

Why that’s the answer

The definition has two parts: the services (compute, storage, networking) are delivered over the internet by a provider, and you rent them on demand rather than owning them, paying for what you use. Running your own servers is on-premises; a multi-year lease bills you whether or not you use the capacity; and a private WAN between your own offices delivers no provider services at all.

How to reason it out

Look for both halves of the definition: delivered over the internet, and rented rather than owned.
Reject anything where you buy and own the hardware (on-premises).
Reject arrangements billed regardless of use, which are not pay-as-you-go.
Choose the option that rents compute, storage, and networking and bills for use.

Exam tip: Cloud computing = renting compute, storage, and networking over the internet, paying only for what you use.

Question 2Describe Azure architecture and services

Which term describes one or more physically separate datacenters within a single Azure region, each with independent power, cooling, and networking?

Choose one.

a
Region pair
A region pair links two whole regions (usually in the same geography) for geo-replication and recovery sequencing; it is not a set of datacenters inside one region.
b
Availability set
An availability set spreads virtual machines across fault and update domains (racks) inside a datacenter; it does not describe separate datacenters with their own power and cooling.
c
Sovereign region
A sovereign region is an isolated instance of Azure, such as Azure Government, kept apart from the global cloud for compliance; it is a whole cloud, not a datacenter grouping inside a region.
d
Availability zone Correct
An availability zone is one or more physically separate datacenters inside a region, each with independent power, cooling, and networking, so one datacenter failing does not take down resources in another zone.

The concept

Availability zones are physically separate datacenters within one Azure region.

Why that’s the answer

The defining facts of an availability zone are: inside one region, physically separate, and independent power, cooling, and networking. An availability set is the tempting near-twin, but it only separates racks (fault and update domains) inside a datacenter. A region pair spans two regions, and a sovereign region is an entire isolated Azure cloud.

How to reason it out

Note the scope: separate datacenters, but still inside a single region.
Match that scope to availability zones.
Separate it from availability sets (racks inside a datacenter), region pairs (two regions) and sovereign regions (isolated clouds).

Exam tip: Separate datacenters inside one region, each with its own power, cooling and network: availability zones.

Question 3Describe Azure management and governance

Your team is designing a new web solution and needs an estimated monthly cost of the Azure services it will use before anything is created in the subscription. Which tool should you use?

Choose one.

a
Cost analysis in Microsoft Cost Management
Cost analysis reports on spend that has already happened in a subscription; a design that has not been deployed has no costs to analyze.
b
An Azure Migrate business case
An Azure Migrate business case is built from discovered on-premises servers you plan to migrate, not from a new design with no existing workload.
c
Azure Advisor cost recommendations
Advisor recommends savings on resources that are already running; it does not price a solution that does not exist yet.
d
The Azure pricing calculator Correct
The pricing calculator lets you add the planned services, choose sizes, regions and hours, and returns an estimated monthly total without provisioning anything.

The concept

The Azure pricing calculator estimates the cost of a planned configuration before deployment.

Why that’s the answer

The pricing calculator is a modelling tool: you add the services you intend to use, set options such as size, region, tier and hours, and it returns an estimate. Nothing is provisioned and nothing is charged. Cost analysis and Advisor both work from resources that already exist, and an Azure Migrate business case starts from on-premises servers that are being migrated, so neither fits a brand-new design with nothing deployed.

How to reason it out

Note that nothing exists in the subscription yet.
Rule out tools that read real usage (cost analysis, Advisor).
Rule out migration tooling, which starts from existing on-premises servers.
Pick the pricing calculator for a pre-deployment estimate.

Exam tip: No resources yet and you need a price? Use the pricing calculator.

Question 4Describe cloud concepts

A developer needs a test server. In the Azure portal she creates a virtual machine in a few minutes, with no purchase order or wait for hardware, and deletes it when testing ends. Which cloud computing characteristic does this show?

Choose one.

a
On-demand provisioning and release of resources Correct
Creating a resource in minutes when needed and removing it when finished is on-demand provisioning, a defining trait of cloud computing.
b
Shared responsibility for securing the resources
Shared responsibility describes who secures which layer; the scenario is about how quickly the server was obtained and released.
c
Dedicated single-tenant hardware for each customer
Dedicated single-tenant hardware describes a private cloud, and nothing in the scenario says the VM runs on dedicated hardware.
d
Capital expenditure on server capacity in advance
Capital expenditure means buying hardware up front; the developer bought nothing and raised no purchase order.

The concept

On-demand provisioning lets you obtain resources in minutes and release them when you no longer need them.

Why that’s the answer

The deciding details are speed and reversibility: the VM existed within minutes without buying hardware, and it was removed when the work ended. That is on-demand provisioning and release. Shared responsibility is about security duties, dedicated hardware is a private-cloud trait, and capital expenditure is the up-front purchase the developer avoided.

How to reason it out

Note what happened: a server appeared in minutes and was deleted afterwards.
Ask which characteristic is about getting and releasing resources when needed.
Rule out the security split, the deployment-model trait, and the up-front spending type.

Exam tip: Get it in minutes, give it back when done: that is on-demand provisioning in the cloud.

Question 5Describe Azure architecture and services

A company in Canada Central wants Azure to copy its storage account data automatically to a second region in the same geography, so that a disaster affecting the whole primary region does not destroy the only copy. Which configuration meets this need?

Choose one.

a
Zone-redundant storage across Canada Central's zones
Zone-redundant storage spreads copies across the availability zones of Canada Central, but every zone is inside that one region, so a region-wide disaster affects every copy.
b
Geo-redundant storage that replicates to East US
Geo-redundant storage replicates only to the primary region's pair, and East US is in the United States geography, not Canada, so this configuration does not exist and would break the same-geography requirement.
c
Geo-redundant storage that replicates to Canada East Correct
Canada Central is paired with Canada East in the Canada geography, and geo-redundant storage replicates asynchronously to the paired region, so a copy survives a region-wide disaster.
d
Geo-redundant storage to a region the company picks
Geo-redundant storage does not let you choose the secondary region; the secondary is always the primary region's pair (Canada East for Canada Central).

The concept

Geo-redundant storage replicates to the primary region's pair, which for most regions is a second region in the same geography.

Why that’s the answer

The requirement is an automatic copy in a different region that is still in the same geography. Geo-redundant storage (GRS) copies data to the primary region's paired region, and Canada Central's pair is Canada East. Zone-redundant storage is tempting because it adds resilience, but it never leaves the region. GRS cannot target an arbitrary region: the secondary is fixed by the pairing, so neither East US nor a region of your choosing is possible.

How to reason it out

Spot the scope of failure: the whole primary region.
Rule out anything that stays inside the region, such as zone-redundant storage.
Recall that GRS always replicates to the region pair, which you cannot choose.
Canada Central's pair is Canada East, in the same geography.

Exam tip: GRS copies to the region pair, fixed by Azure; zone-redundant storage never leaves the region.

How AZ-900 questions are worded

Most AZ-900 questions are not asking whether you can recall a definition. They describe a situation and ask which option satisfies it — so the skill being tested is reading the requirement precisely and eliminating options that fail it.

Single-response vs multiple-response

A single-response question has exactly one right answer. A multiple-response question tells you how many to pick ("Choose TWO") and there is no partial credit — getting one of the two right scores nothing. Read that instruction before you read the options.

Read the last line first

The final sentence is the actual question; everything before it is scenario. Read it first, then read the scenario knowing what you are looking for. It stops you from building an answer in your head that the question never asked for.

Hunt for the qualifier

Most scenarios turn on one word — MOST cost-effective, LEAST operational overhead, with the LEAST latency, without changing application code. Two options are frequently both technically correct, and the qualifier is the only thing separating them.

Eliminate, then choose

Distractors are almost always real Microsoft Azure services doing a real job — just not this job. Rule out the ones that break a stated constraint before you compare what's left. On a question you truly don't know, eliminating two options turns a guess into a coin flip.
