Question 220 A team wants to run its own code but is willing to accept service-imposed runtime restrictions in exchange for less server administration. Which model fits? Infrastructure as a service requiring full guest administration Private-owned bare metal without managed hosting Software as a service for a vendor's complete product Platform as a service Explanation Correct Answer D:PaaS trades host control for managed application execution and deployment. Incorrect Answers A:IaaS gives more control but more maintenance burden. B:Owning a server increases infrastructure duties. C:SaaS does not expose a general platform for custom application code.
Question 221 A team needs virtual machines, virtual networks and attached disks to build its own server architecture. Which model describes these primitives? An employee desktop app license Software as a service Infrastructure as a service Platform as a service Explanation Correct Answer C:IaaS exposes compute, networking and storage resources for tenant-managed workloads. Incorrect Answers A:A local app license is not rented cloud infrastructure. B:SaaS is finished application functionality rather than raw VM resources. D:PaaS abstracts much of the guest OS and underlying infrastructure.
Question 222 Developers need a database engine provided as a service without building the VM cluster underneath it. Which model is closest? Platform as a service A finished SaaS collaboration suite A file copy utility with no query engine Infrastructure as a service with self-installed database servers Explanation Correct Answer A:Managed databases expose database capabilities with platform operations handled by the provider. Incorrect Answers B:A hosted collaboration app is not a general custom database backend. C:File transfer does not supply a managed database service. D:IaaS requires database/OS administration.
Question 223 A SaaS user can configure their app preferences but cannot resize its provider-owned servers. Which boundary is being illustrated? SaaS tenant configuration without infrastructure control IaaS guest root administration Private cloud hardware ownership PaaS custom application deployment Explanation Correct Answer A:A finished hosted application exposes permitted settings, not arbitrary server administration. Incorrect Answers B:VM tenants may manage guest servers and sizing. C:Owning dedicated hosts differs from SaaS application use. D:PaaS is for deploying tenant code on managed runtimes.
Question 224 As a team moves from IaaS to PaaS to SaaS, what usually happens to the provider's share of platform operations? Every application can always migrate without redesign The customer must maintain more physical provider hardware The provider manages progressively more of the software stack Business data accountability always disappears Explanation Correct Answer C:From IaaS infrastructure to SaaS complete applications, underlying responsibility typically shifts provider-ward. Incorrect Answers A:Different service abstractions have different compatibility constraints. B:Cloud models do not transfer provider datacenter ownership to customers. D:The organization still governs its users and data.
Question 225 A company relies on a vendor application that requires a legacy supported Windows guest and administrator installation. Which service model is most direct? Object storage alone PaaS managed web app runtime SaaS vendor office tools IaaS hosted virtual machines Explanation Correct Answer D:VMs provide the guest OS environment needed for legacy installers. Incorrect Answers A:Files in storage do not run the legacy program. B:Managed runtimes may not allow required OS installation paths. C:Finished SaaS apps cannot host arbitrary installer software.
Question 226 A team has authored a custom ecommerce site but wants rapid deployment and integrated runtime scaling. Which service model fits its application? A bare IaaS VM with manual server administration SaaS finished accounting system A data archive with no application execution PaaS managed application hosting Explanation Correct Answer D:The platform operates underlying servers while the team owns website code. Incorrect Answers A:A VM works but leaves maintenance the team seeks to avoid. B:An accounting application is not a runtime for custom commerce code. C:Storage cannot run the ecommerce logic.
Question 227 A small firm wants a finished payroll program with vendor updates, not a new development project. Which service model is best? IaaS VM with only an operating system PaaS blank runtime for self-written payroll A public IP address as the application SaaS hosted payroll application Explanation Correct Answer D:The vendor supplies and operates the completed business function. Incorrect Answers A:A VM does not provide payroll functionality by itself. B:The company would need to develop payroll code. C:Network addressing is not payroll processing software.
Question 228 An organization must modify the source code of its unique ERP system and run custom service components. What cloud model is usually most appropriate? IaaS or suitable PaaS that permits customer code SaaS always includes unrestricted vendor source access Purchase a SaaS package and assume it permits arbitrary changes to the provider's application source A backup vault as the entire production runtime Explanation Correct Answer A:Unlike an off-the-shelf SaaS product, infrastructure or platform hosting can run custom implementations. Incorrect Answers B:SaaS tenant features do not guarantee changing the vendor's product source. C:SaaS customers normally use supported configuration and extensions rather than rewrite vendor-operated application internals. D:Backup storage does not operate custom ERP components.
Question 229 A distributor subscribes to a finished B2B ordering portal delivered by an outside software company. What is the distributor primarily consuming? A physical server purchase IaaS raw compute with no ordering application SaaS application functionality PaaS runtime requiring the distributor to write the app Explanation Correct Answer C:The distributor uses an existing hosted product rather than operating its servers. Incorrect Answers A:Buying hardware is not the same as consuming SaaS. B:VM capacity alone does not supply B2B workflows. D:The portal is already developed and vendor-operated.
Question 230 A firm hosts a custom application on VMs. Who should plan the application-level recovery sequence after an outage? Only the provider's datacenter construction team Every end user independently without coordination An unrelated SaaS vendor The customer's workload owner Explanation Correct Answer D:Azure manages infrastructure but the customer knows data consistency, application order and business recovery requirements. Incorrect Answers A:Facility teams do not design the tenant's app recovery sequence. B:Workload recovery requires a controlled operational plan.
