Question 1Cloud Concepts
A retail company runs its e-commerce platform in its own datacentre. During holiday sales, traffic increases tenfold, requiring servers that sit idle the rest of the year. Which cloud benefit would MOST directly address this problem?
A ✓Elasticity — automatically scaling resources up during peaks and down afterwards
BDisaster recovery — replicating workloads to a second region
CHigh availability — ensuring services remain accessible during failures
DPredictive maintenance — using AI to anticipate hardware failures
Explanation: Elasticity is the ability to automatically scale resources to match demand — exactly the holiday-peak problem. The company pays for extra capacity only when needed, instead of owning idle servers year-round. High availability and disaster recovery address different concerns (uptime and recovery), not fluctuating demand.
Question 2Cloud Concepts
Your CFO wants to stop large upfront hardware purchases and instead pay monthly based on actual usage. Which financial model shift does moving to the cloud provide?
A ✓CapEx to OpEx — capital expenditure becomes operational expenditure
BOpEx to CapEx — operational expenditure becomes capital expenditure
CFixed cost to sunk cost accounting
DDepreciation-based to amortisation-based accounting
Explanation: Cloud computing shifts spending from capital expenditure (CapEx — large upfront purchases of hardware that depreciate) to operational expenditure (OpEx — ongoing pay-as-you-go costs). This improves cash flow and removes the risk of over-provisioning hardware.
Question 3Cloud Concepts
A hospital must keep patient records on servers it physically controls due to regulation, but wants to run its public website and appointment booking system in Azure. Which cloud model fits?
APublic cloud only
BPrivate cloud only
C ✓Hybrid cloud
DCommunity cloud
Explanation: Hybrid cloud combines private infrastructure (the regulated patient records staying on-premises) with public cloud services (the website and booking system in Azure). This is the classic hybrid use case: keeping sensitive workloads local while using public cloud for scalable public-facing services.
Question 4Cloud Concepts
In the shared responsibility model, which responsibility ALWAYS remains with the customer, regardless of whether they use IaaS, PaaS, or SaaS?
APhysical security of datacentres
B ✓Information and data, devices, and accounts and identities
COperating system patching
DNetwork infrastructure maintenance
Explanation: The customer always retains responsibility for their data, their devices, and their accounts/identities — in every service model. Physical security always belongs to the cloud provider. OS patching shifts depending on the model (customer in IaaS, provider in PaaS/SaaS).
Question 5Cloud Concepts
A startup wants to deploy a web application without managing virtual machines, operating systems, or runtime environments — they just want to deploy code. Which service model should they choose?
AIaaS — Infrastructure as a Service
B ✓PaaS — Platform as a Service
CSaaS — Software as a Service
DOn-premises with automation tools
Explanation: PaaS provides the platform (OS, runtime, middleware) fully managed — developers just deploy code. Azure App Service is the classic example. IaaS would still require managing the OS; SaaS is consuming finished software (like Microsoft 365), not deploying your own code.
Question 6Cloud Concepts
Which of the following is the BEST example of Software as a Service (SaaS)?
AAzure Virtual Machines
BAzure App Service
C ✓Microsoft 365 (Outlook, Word, Excel online)
DAzure Kubernetes Service
Explanation: Microsoft 365 is finished software consumed over the internet — the definition of SaaS. Users don't manage any infrastructure, platform, or code. Virtual Machines are IaaS; App Service and AKS are PaaS offerings where you still deploy your own applications.
Question 7Cloud Concepts
A company experiences a regional power outage that takes down its only datacentre for two days, halting all business operations. Which cloud benefit would have prevented this business impact?
AScalability
B ✓Disaster recovery through geographic distribution
CPay-as-you-go pricing
DServerless computing
Explanation: Disaster recovery via geographic distribution means workloads can fail over to another region when one fails. Azure's paired regions are designed exactly for this. Scalability handles demand changes, not outages; pricing models and serverless don't address regional failure.
Question 8Cloud Concepts
What does 'high availability' mean in cloud computing?
AThe ability to recover data after accidental deletion
B ✓Ensuring services remain operational and accessible for a high percentage of time, often expressed as uptime SLA
CThe ability to serve users in many geographic regions
DAutomatically increasing compute power during traffic spikes
Explanation: High availability means maximising uptime — keeping services accessible despite failures, typically measured as an SLA percentage like 99.9%. Azure achieves this through redundancy: availability zones, load balancing, and fault domains. Geographic reach is global distribution; scaling is elasticity.
Question 9Cloud Concepts
A development team needs identical test environments created and destroyed dozens of times per day. Manually building each one takes hours. Which cloud characteristic solves this MOST directly?
A ✓Self-service and automation via templates and APIs
BHigh availability zones
CContent delivery networks
DReserved capacity pricing
Explanation: Cloud self-service and automation (using ARM templates, Bicep, or APIs) lets teams programmatically create and destroy identical environments in minutes. This agility is a core cloud benefit. Availability zones, CDNs, and pricing models don't address environment provisioning speed.
Question 10Cloud Concepts
Which statement BEST describes the consumption-based pricing model?
AYou pay a fixed monthly fee regardless of usage
B ✓You pay only for the resources you actually use, with no upfront cost
CYou pre-purchase capacity for one or three years at a discount
DYou pay per user per month
Explanation: Consumption-based (pay-as-you-go) means paying only for actual usage — compute seconds, storage consumed, transactions processed — with no upfront commitment. Reserved instances are the pre-purchase model; per-user pricing is typical of SaaS licensing.
Question 11Azure Architecture & Services
A company needs to run a legacy Windows application that requires full control over the operating system, custom registry settings, and specific driver installations. Which Azure service should they use?
AAzure App Service
B ✓Azure Virtual Machines
CAzure Functions
DAzure Container Instances
Explanation: Azure Virtual Machines (IaaS) provide full OS control — registry, drivers, custom configurations. App Service and Functions are PaaS/serverless where the OS is abstracted away. Legacy applications requiring OS-level customisation are the classic VM use case.
Question 12Azure Architecture & Services
What is an Azure Region?
AA single physical datacentre building
B ✓A set of datacentres deployed within a latency-defined perimeter, connected through a dedicated low-latency network
CA billing boundary for Azure subscriptions
DA virtual network spanning multiple countries
Explanation: An Azure region is one or more datacentres within a latency-defined perimeter connected by a dedicated low-latency network. Regions are the primary unit of geographic deployment. A single building is a datacentre; billing boundaries are subscriptions.
Question 13Azure Architecture & Services
An application must survive the failure of an entire datacentre within a region without downtime. Which Azure feature should the architecture use?
A ✓Availability Zones — physically separate datacentres within a region
BResource groups
CAzure DNS
DA larger virtual machine size
Explanation: Availability Zones are physically separate datacentres within a region, each with independent power, cooling, and networking. Deploying across zones protects against datacentre-level failure. Resource groups are logical containers, not resilience features.
Question 14Azure Architecture & Services
Which Azure storage service is BEST suited for storing large amounts of unstructured data such as images, videos, and documents?
AAzure SQL Database
B ✓Azure Blob Storage
CAzure Virtual Network
DAzure Cosmos DB
Explanation: Blob (Binary Large Object) Storage is designed for unstructured data — images, videos, documents, backups. SQL Database is for relational data; Cosmos DB for globally distributed NoSQL; Virtual Network is networking, not storage.
Question 15Azure Architecture & Services
A company wants code to run automatically whenever a file is uploaded to storage — paying only for the milliseconds of execution time, with no servers to manage. Which service fits?
AAzure Virtual Machines
B ✓Azure Functions
CAzure Virtual Desktop
DAzure ExpressRoute
Explanation: Azure Functions is serverless compute — code triggered by events (like file uploads), billed per execution, with zero server management. This event-driven, pay-per-execution model is exactly the scenario described. VMs require management; AVD is desktop virtualisation; ExpressRoute is networking.
