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, and studying leaked ones ("brain dumps") violates the Microsoft Azure certification agreement and can get your certification revoked. These questions are written from scratch against the published AZ-900 exam guide to match its style, difficulty and domain weighting.

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
The delivery of computing services such as compute, storage, and networking over the internet on a pay-as-you-go basis Correct
This captures the core definition: on-demand delivery of compute, storage, and networking over the internet, paid as you use it.
b
Buying and installing physical servers in your own room and maintaining them yourself
This describes a traditional on-premises datacenter, which is what cloud computing replaces.
c
A single application that stores files only on a local hard drive
Local file storage on one device is not cloud computing, which delivers shared resources over the internet.
d
A high-speed internet connection sold by a telecommunications company
Connectivity alone is not cloud computing; the cloud provides compute, storage, and networking resources you rent on demand.

The concept

Cloud computing is the on-demand delivery of computing services over the internet.

Why that’s the answer

The correct answer names the three service categories (compute, storage, networking) delivered over the internet on a pay-as-you-go basis, which is the exam definition. Buying and running your own servers is on-premises, not cloud; a local-only app and an internet connection are neither the delivery of rentable resources nor pay-as-you-go.

How to reason it out

Recall that cloud computing means renting technology rather than owning it.
Check that the answer mentions delivery of resources over the internet.
Confirm it includes the pay-as-you-go idea, which separates it from on-premises.

Exam tip: Cloud computing is the on-demand delivery of compute, storage, and networking over the internet, paid for as you use it.

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
Availability zone Correct
An availability zone is one or more physically separate datacenters inside a region, each with its own power, cooling, and networking, so a single datacenter failure does not take down resources in another zone.
b
Region pair
A region pair joins two separate regions hundreds of miles apart for disaster recovery, not separate datacenters within one region.
c
Geography
A geography is a larger grouping of regions used for data-residency and compliance, not the separate datacenters inside a single region.
d
Resource group
A resource group is a logical container for resources; it has nothing to do with physical datacenter separation.

The concept

Availability zones are physically separate datacenters within one Azure region.

Why that’s the answer

An availability zone is defined as one or more physically separate datacenters in a region with independent power, cooling, and networking, so it protects against a single datacenter failing. A region pair is about two whole regions far apart, a geography is a broad grouping of regions, and a resource group is a logical (not physical) container, so none of those match the definition.

How to reason it out

Look for the trigger: physically separate datacenters inside one region.
Match that phrase to the availability zone definition.
Rule out region pair, geography, and resource group as different-scope concepts.

Exam tip: Physically separate datacenters within a region equals availability zones.

Question 3Describe Azure management and governance

Your team is planning a new solution and wants an estimated monthly cost of the Azure services before any resources are deployed. Which tool should you use?

Choose one.

a
The Azure Pricing Calculator Correct
The Pricing Calculator estimates the cost of Azure services you configure by hand, so it is the right tool for projecting cost before deployment.
b
Microsoft Cost Management
Cost Management reports on actual spend after resources are running; it cannot estimate a design that does not exist yet.
c
The Total Cost of Ownership (TCO) Calculator
The TCO Calculator compares an on-premises environment with Azure; it is not used to price a specific set of planned Azure services.
d
Azure Advisor
Azure Advisor gives recommendations on existing resources; it does not build a pre-deployment cost estimate.

The concept

The Azure Pricing Calculator projects the cost of a proposed workload before it is deployed.

Why that’s the answer

The Pricing Calculator lets you add services and settings and returns an estimated monthly total, which is exactly what pre-deployment planning needs. Cost Management only reports real spend after deployment, the TCO Calculator answers the on-premises-versus-Azure question, and Advisor gives optimization recommendations on live resources, so none of those fit an estimate for a design that does not exist yet.

How to reason it out

Note the key phrase: estimate cost before deploying.
Match a pre-deployment estimate to the Pricing Calculator.
Rule out tools that need live resources or answer a different question.

Exam tip: Estimate cost before deploying with the Azure Pricing Calculator.

Question 4Describe cloud concepts

A company can create a virtual machine in Microsoft Azure in minutes and switch it off when it is no longer needed. Which characteristic of cloud computing does this describe?

Choose one.

a
On-demand access to resources Correct
Requesting resources when needed and releasing them when done is exactly what on-demand access means.
b
A capital expense
A capital expense is a large up-front purchase of owned hardware, not the ability to turn resources on and off quickly.
c
A private deployment model
A private cloud describes who uses the hardware, not the speed of provisioning resources on demand.
d
Physical ownership of the datacenter
In the cloud the provider owns the datacenter; the customer does not own or house the hardware.

The concept

On-demand provisioning lets you start and stop resources quickly.

Why that’s the answer

Creating a resource in minutes and stopping it when done is the definition of on-demand access. A capital expense is about buying assets, a private model is about who shares the hardware, and datacenter ownership belongs to the provider, so none of those describe rapid provisioning.

How to reason it out

Identify the behavior: resources appear in minutes and stop when unused.
Match that behavior to on-demand access.
Eliminate options about cost type, deployment model, and ownership.

Exam tip: Turning resources on in minutes and off when done is on-demand access, a hallmark of cloud computing.

Question 5Describe Azure architecture and services

An organization wants two Azure regions that are hundreds of miles apart so it can recover if one entire region suffers a major outage. Which Azure concept provides this?

Choose one.

a
Region pair Correct
Region pairs join two regions in the same geography at least hundreds of miles apart, supporting disaster recovery and data replication if an entire region goes down.
b
Availability zone
Availability zones protect against a single datacenter failing inside one region, not against an entire region going down.
c
Subscription
A subscription is a billing and access boundary, not a mechanism for regional disaster recovery.
d
Management group
A management group organizes multiple subscriptions; it does not provide geographic resilience.

The concept

Region pairs provide disaster recovery across two distant regions.

Why that’s the answer

A region pair links two regions hundreds of miles apart so a single large event is unlikely to affect both, which is exactly the region-outage protection described. Availability zones only cover a datacenter failure inside one region, while subscriptions and management groups are logical billing and organization boundaries, not resilience features.

How to reason it out

Identify the need: recovery from an entire region failing.
Recall that region pairs sit hundreds of miles apart for disaster recovery.
Reject availability zones (within-region) and the logical boundaries.

Exam tip: Protection against a whole region failing points to region pairs.

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.
