Question 190 A cloud manager confuses guest OS firewall administration with physical datacenter firewall upkeep. Which layer does a typical IaaS customer configure? Physical security gates in Microsoft datacenters Guest and virtual-network security for its resources Building power distribution for Azure regions Provider-host hardware firmware Explanation Correct Answer B:Tenant-level security policies differ from provider-owned physical perimeter controls. Incorrect Answers A:Facility access is provider-operated. C:Power infrastructure is outside the tenant's controls. D:Host maintenance is not the tenant's virtual rule administration.
Question 191 A startup develops its own website but wants managed hosting without direct server OS patching. Which service type fits? IaaS VMs with tenant guest patching Platform as a service Software as a service for a vendor's finished website A colocated physical server Explanation Correct Answer B:PaaS hosts custom application code on a provider-managed runtime. Incorrect Answers A:A VM would leave more server management to the startup. C:SaaS doesn't by itself run arbitrary customer web application code. D:Colocation retains hardware and software maintenance duties.
Question 192 Developers need a managed application environment for supported code frameworks. What is primarily provided by PaaS? A guarantee that application logic is always correct Unrestricted physical hardware access in the provider's datacenter A runtime platform, deployment features and managed supporting infrastructure A completed vendor CRM business workflow only Explanation Correct Answer C:The provider abstracts hosts while developers deliver applications. Incorrect Answers A:PaaS doesn't validate every program or business rule. B:Platform customers do not administer the physical racks. D:That describes finished SaaS consumption rather than custom code hosting.
Question 193 A team changes from a database running on a VM to a managed Azure relational database. What operations difference is expected? The provider automatically writes correct business queries No database access control is necessary The customer must patch the provider's underlying database host OS Reduced guest OS and database platform administration Explanation Correct Answer D:Managed databases handle supported platform maintenance, while customers keep schema and query design duties. Incorrect Answers A:Data modeling and query behavior still require customer work. B:A managed engine still needs secure identities and permissions. C:Managed platform operations are provider-owned.
Question 194 An application needs arbitrary root access to install a custom system driver. Why might a typical PaaS plan be inappropriate? Choose a managed PaaS runtime and expect arbitrary host kernel drivers to work PaaS always provides full host administrator control SaaS guarantees the customer can modify provider drivers The platform abstracts and restricts guest OS-level changes Explanation Correct Answer D:Managed hosting can limit installation of arbitrary kernel or system components. Incorrect Answers A:PaaS hosting hides the underlying host OS and generally restricts installing unsupported kernel components. B:That is inconsistent with managed runtime boundaries. C:A finished app gives even less host control.
Question 195 A developer wants Azure to maintain the hosting environment while the team focuses on application code. Which feature of PaaS is relevant? Provider-managed operating platform and runtime updates Automatic prevention of every application logic bug Customer replacement of the rack-mounted servers Required manual patching of all platform hypervisors by developers Explanation Correct Answer A:The service abstracts much of the underlying maintenance. Incorrect Answers B:Managed runtime does not certify custom code correctness. C:Host hardware maintenance is not tenant work in PaaS. D:PaaS removes those underlying infrastructure duties.
Question 196 A company deploys a payroll API on a managed Azure application platform. Which responsibility remains with the tenant? Firmware patches for the provider's hypervisors Datacenter cooling control Secure application authorization and management of business data Physical disk replacement for the managed runtime Explanation Correct Answer C:Provider platform patching does not grant employees appropriate payroll access. Incorrect Answers A:Host firmware is outside the tenant's PaaS scope. B:Physical facility operation is provider responsibility. D:The cloud provider maintains hardware.
Question 197 A development team uses managed application slots to test updates before switching production traffic. Which service-model advantage is this? Managed platform deployment features for custom application code Only a static file archive with no runtime Finished SaaS application functionality with no developer code Mandatory bare-metal provisioning for every release Explanation Correct Answer A:PaaS can supply release tooling without the team manually managing servers. Incorrect Answers B:An archive cannot run and switch application versions. C:The team is deploying its own program. D:PaaS avoids physical procurement per deployment.
Question 198 A team hosts a supported API on PaaS and needs additional instances during high traffic. Which approach is suitable? Assume managed hosting always means one fixed capacity forever Resize a single application administrator VM rather than increase PaaS hosting capacity Patch Azure datacenter hosts directly Use the platform's supported scaling configuration Explanation Correct Answer D:Managed runtime services can offer capacity controls without per-VM administration. Incorrect Answers A:PaaS often has scaling options dependent on tier. B:A management VM's size does not increase the managed API application's own serving instances. C:Customers do not maintain physical provider hosts.
Question 199 An Azure app uses managed database services but must still control schema design and indexes. What service boundary does this demonstrate? The provider creates every domain-specific table automatically A SaaS license can replace all database logic without migration IaaS always eliminates guest patching duties PaaS manages database hosting while the customer governs data design and workloads Explanation Correct Answer D:Platform automation does not design all tenant queries and schemas. Incorrect Answers A:Business data modeling remains customer-specific. B:A finished app is not a drop-in substitute for any custom schema. C:An IaaS database server normally retains guest maintenance.
Question 200 A team deploys its container image into a managed hosting platform with autoscaling but without managing worker VMs. What cloud service abstraction is emphasized? A self-managed virtual machine fleet as the only possible container host An end-user SaaS product with no deployable application code A requirement to purchase individual physical servers Managed platform hosting for containerized application workloads Explanation Correct Answer D:The tenant provides the image while the platform manages scheduling and host capacity. Incorrect Answers A:Containers can also run on managed platform services. B:The tenant is running its own container. C:Managed hosting abstracts the hardware purchase.
