Question 250 A solution uses Azure VMs for a legacy engine, managed databases for new APIs and SaaS for employee collaboration. How should its cloud service model be described? A mix of IaaS, PaaS and SaaS components Pure SaaS because users have collaboration apps Pure IaaS because any VM exists A rule that service models cannot coexist Explanation Correct Answer A:One organization can combine different service abstractions for different workloads. Incorrect Answers B:The architecture still includes tenant-managed infrastructure. C:Other managed services remain PaaS and SaaS. D:Cloud deployments can combine models.
Question 251 A business moves its website to managed hosting and asks whether no performance decisions remain. What still must the team plan? All physical datacenter switch replacement Assume the selected PaaS plan has infinite throughput and no dependency limits An assumption that every managed tier is infinite Application sizing, scaling rules and dependency capacity Explanation Correct Answer D:PaaS manages hosts but the tenant still configures workload behavior and suitable service tiers. Incorrect Answers A:That is provider operations. B:Managed platforms retain resource limits and may require scaling configuration as traffic grows. C:PaaS plans have limits and pricing considerations.
Question 252 Several companies use the same hosted application vendor. What tenant protection should the service enforce? Public read access to every tenant's records No sign-in control because the platform is hosted Logical separation of each customer's accounts and data One common administrator identity for all unrelated customers Explanation Correct Answer C:Shared SaaS infrastructure must maintain authorization boundaries between organizations. Incorrect Answers A:Multi-tenant SaaS does not imply unrestricted disclosure. B:Hosted access still needs authentication and authorization. D:Shared access would defeat tenant separation.
Question 253 A self-managed application on Azure VMs needs a tested recovery plan. Which team defines application restore order and validates usable data? The VM's CPU manufacturer alone The tenant owning the workload An arbitrary SaaS email provider The provider's cooling system contractor Explanation Correct Answer B:Provider infrastructure resilience does not determine the app's recovery dependencies. Incorrect Answers A:Processor hardware is not the application recovery owner. C:An unrelated app does not design this VM workload's recovery. D:Facility maintenance does not know the app's dependency graph.
Question 254 A customer wants the underlying operating system logs from a finished SaaS vendor's server. Which expectation is appropriate? Every SaaS subscription includes kernel log shell access Storage billing reports contain all application security events Use vendor-exposed application and audit logs rather than assuming host OS access Assume the SaaS administrator can inspect the provider's private host audit logs directly Explanation Correct Answer C:SaaS abstracts provider infrastructure and offers supported tenant-level diagnostics. Incorrect Answers A:Host OS access is not generally provided to tenants. B:Cost records are not complete security audit logs. D:SaaS tenant telemetry is limited to the application's exposed monitoring and export capabilities.
Question 255 A team runs a managed web application on an Azure service plan. Which cost consideration is appropriate? Charges depend on the selected managed hosting plan and usage conditions Resource group names are the sole billing units Billing occurs only when a user edits source code Managed hosting is always free regardless of tier or load Explanation Correct Answer A:PaaS abstracts servers but still has service-specific pricing. Incorrect Answers B:Resource groups organize infrastructure but do not set every price. C:Hosted capacity may incur charges even without code updates. D:Paid platform tiers and usage-based pricing exist.
Question 256 An organization creates a reusable VM image containing its configured application. What responsibility remains during image creation and maintenance? Replace Azure hardware each time an image is updated Keep tenant software, guest OS components and configuration secure and current Install SaaS vendor server updates from the customer's image Update Microsoft's physical hypervisors within the image Explanation Correct Answer B:Reusable images can propagate outdated software if not maintained. Incorrect Answers A:Images are software artifacts, not physical host replacements. C:An unrelated vendor host is not part of the VM template. D:Provider host firmware is not included in the guest image.
Question 257 A hosted CRM is unavailable due to a vendor-wide outage. What should the customer understand about responsibility and continuity? The tenant can repair the vendor hypervisor as root The vendor operates recovery, while the customer still needs a business continuity response Renaming a corporate resource group will fix the CRM outage The provider automatically fulfills every customer continuity obligation Explanation Correct Answer B:SaaS provider restoration and tenant contingency planning are complementary. Incorrect Answers A:SaaS customers do not manage the provider's hosts. C:Unrelated Azure metadata cannot repair SaaS backend operations. D:Tenants may need alternate workflows and communication.
Question 258 A PaaS vendor schedules a supported platform runtime deprecation. Which customer task may remain? Developers must patch the host hypervisor directly Update and test application code for compatibility with supported runtimes SaaS vendor application changes eliminate custom runtime constraints Replace the provider's physical memory modules Explanation Correct Answer B:Provider-managed platform updates can still require customer code adjustments. Incorrect Answers A:Host virtualization is outside the PaaS tenant boundary. C:Custom apps still need compatibility planning. D:Hardware is managed by the provider.
Question 259 A team uses Azure VMs for a stateful custom backend and needs more throughput. Which responsibility falls to the team? Assume the application scales without configuration Approve the provider's cooling system maintenance Determine which Azure datacenter roof needs repair Plan VM sizing, application scaling and state management Explanation Correct Answer D:IaaS provides resources but not automatic application architecture decisions. Incorrect Answers A:VM provisioning does not automatically redesign stateful code. B:Host facilities are outside tenant VM capacity planning. C:Facilities remain provider-operated.
Question 260 A company pays for SaaS licenses for 100 users. Which statement about access is most accurate? The SaaS provider knows each employee's job duties by default Licensing and actual authorization must both be managed Application roles are unnecessary with paid licenses Any licensed user becomes global administrator automatically Explanation Correct Answer B:Buying seats does not mean every user should access every tenant record. Incorrect Answers A:The customer must assign suitable business roles. C:Least-privilege authorization remains relevant. D:A seat does not confer universal privilege.
