Question 1 An online retailer wants to run application servers without purchasing or maintaining the physical machines in its own building. Which description best fits the arrangement? A colocation contract where the retailer owns and maintains every server Cloud computing supplies remotely hosted computing resources on demand A software license installed exclusively on employee laptops An office network with only locally owned equipment Explanation Correct Answer B:The provider operates underlying facilities while the retailer uses provisioned compute over a network. Incorrect Answers A:Colocation rents space but does not inherently provide managed on-demand compute resources. C:A local license is not the delivery of remote shared computing resources. D:Local infrastructure still leaves the retailer responsible for purchasing the hardware.
Question 2 A shopping site needs dozens of extra web instances during a weekend sale and far fewer on Monday. Which cloud characteristic is most useful? Manually replacing the application code every time traffic changes A fixed hardware purchase sized for the peak all year Keeping the same server count regardless of traffic Elastic capacity that expands and contracts with demand Explanation Correct Answer D:Elastic resources can be added for the sale and released afterward to reduce idle capacity. Incorrect Answers A:Code changes do not supply the extra instances needed for a temporary demand spike. B:Buying peak capacity leaves expensive machines unused outside sale periods. C:Unchanged capacity fails either peak responsiveness or off-peak efficiency.
Question 3 A development team wants to create test compute in minutes through a portal rather than file a purchasing request for each server. What cloud property supports this? A separate application deployment with no available compute A contract requiring fixed equipment orders each quarter Manual rack installation before every test On-demand self-service provisioning Explanation Correct Answer D:Authorized users can request service capacity without a separate physical procurement cycle. Incorrect Answers A:Deployment automation cannot provision capacity unless compute resources are available. B:Quarterly procurement prevents immediate self-service creation of test instances. C:Physical installation is the delay the team wants to avoid.
Question 4 A field workforce must reach a hosted collaboration application from different locations and supported devices. Which cloud principle explains that access model? The service can be used only at the provider's datacenter All traffic must originate from one office LAN Broad network access through standard connectivity Every user must purchase an identical physical server Explanation Correct Answer C:A network-accessible service can be used from multiple locations without requiring a dedicated local server per site. Incorrect Answers A:That would defeat the requested distributed access model. B:Restricting access to one LAN conflicts with remote workforce requirements. D:Device access does not require individual ownership of backend hosts.
Question 5 Two customers run independent applications on a provider's shared physical infrastructure while their workloads remain logically isolated. What concept is illustrated? A single unvirtualized server with one customer's only workload Unrestricted cross-tenant data access A private datacenter owned separately by every user Resource pooling with tenant isolation Explanation Correct Answer D:The provider allocates common infrastructure among customers while enforcing tenant boundaries. Incorrect Answers A:A single dedicated workload does not illustrate pooled multi-tenant capacity. B:Resource pooling does not remove isolation or access controls. C:Dedicated ownership is not shared infrastructure allocation across tenants.
Question 6 A business wants its monthly cloud bill to reflect the amount of processing and storage it actually consumes. Which characteristic is central? Free unlimited compute without any service limits A mandatory identical bill regardless of service use Measured service and consumption-based billing An accounting method based only on employee headcount Explanation Correct Answer C:Usage metering connects charges to consumed resources subject to each service's pricing rules. Incorrect Answers A:Cloud services normally have pricing and quotas rather than unlimited free use. B:A constant flat charge does not reflect the requested usage measurement. D:Employee totals do not measure the consumed cloud resources.
Question 7 A company runs VMs in Azure and asks who maintains the physical datacenter building and cooling systems. Who is responsible? Microsoft as the cloud provider The customer's application developers The customer's end users Every VM guest operating system administrator Explanation Correct Answer A:Azure operates the physical facility and underlying hosting infrastructure. Incorrect Answers B:Developers manage code but do not operate Microsoft's datacenter cooling systems. C:Users are not responsible for maintaining the provider's building. D:Guest OS administration is distinct from physical facility operations.
Question 8 A company deploys an Azure virtual machine running its chosen Windows Server configuration. Who normally installs guest OS updates and security patches? An external internet service provider automatically The customer operating the IaaS virtual machine Microsoft solely because Azure owns the physical server The availability zone operator as a separate organization Explanation Correct Answer B:With IaaS the tenant manages its guest operating system and its patch configuration. Incorrect Answers A:Network connectivity providers do not administer the customer's Azure VM guest OS. C:Provider physical infrastructure responsibility does not include the tenant's chosen VM guest patching. D:An availability zone is an Azure infrastructure boundary, not the customer's OS administration team.
Question 9 An organization hosts a custom payroll program on an Azure VM. Who is accountable for correcting vulnerabilities in its application code? The VM hypervisor automatically by design The organization that develops and operates the program The employee who views the payslip Azure datacenter maintenance staff Explanation Correct Answer B:Cloud infrastructure does not shift ownership of custom application defects away from the customer. Incorrect Answers A:A hypervisor does not fix vulnerabilities in tenant application source code. C:An end user is not the owner of application code maintenance. D:Datacenter staff keep infrastructure running; they do not rewrite the customer's payroll logic.
Question 10 A business stores customer records in Azure Storage. Who decides which records are confidential and which employees should access them? The electricity supplier for the Azure region Every external partner by default Microsoft based solely on the storage account SKU The business that owns the records Explanation Correct Answer D:Customers retain responsibility for classifying data and designing appropriate access permissions. Incorrect Answers A:Power delivery has no role in customer data classification. B:Partners should not make the data owner's classification decisions. C:The SKU cannot determine business sensitivity or employee authorization.
