Question 90 A developer wants to distribute incoming calls across interchangeable cloud instances. What design aids this objective? Store the only session copy on ephemeral VM memory Hardcode all requests to one long-running server Keep instances stateless or store durable state outside the instance Turn off health probes on every instance Explanation Correct Answer C:Requests can be served by different instances without relying on local process memory. Incorrect Answers A:Instance replacement can erase needed session state. B:Single-instance dependence blocks easy redistribution. D:Without health awareness, traffic can reach failed workers.
Question 91 An application requires a reliability commitment. What should an architect check before choosing an Azure SKU? Which availability and redundancy features the exact SKU and deployment support Assume buying a resource group guarantees zone resiliency Assume every free tier has identical production SLAs Rely only on the word cloud in the product name Explanation Correct Answer A:Feature and SLA coverage can depend on service tier and architecture. Incorrect Answers B:Groups organize resources but do not add redundancy by themselves. C:Tiers can have different commitments and limits. D:Hosting category alone is not an SLA specification.
Question 92 An operations team wants autoscaling but fears a buggy request loop could create excessive resources. What additional governance should accompany elasticity? Assume autoscaling guarantees a fixed bill Give every user unlimited production deployment rights Remove all monitoring to reduce alert noise Quotas, monitoring and cost alerts appropriate to the service Explanation Correct Answer D:Elastic services still need controls against runaway usage or spend. Incorrect Answers A:More resource use can raise consumption costs. B:Unrestricted privileges can increase operational risk. C:Without visibility the team cannot detect unintended scale and expense.
Question 93 A company retains historical records for compliance and almost never reads them. Which consumption consideration is especially important? Ignore retention and deletion obligations because the cloud holds the bits Budget only for VM CPU cycles Always select the fastest hot storage for every dormant file Match storage lifecycle and access pricing to retrieval frequency Explanation Correct Answer D:A lower storage rate may be offset by retrieval cost and access delays if objects are used often. Incorrect Answers A:Data lifecycle rules still apply. B:Object storage can incur costs without active VM workloads. C:Premium access can be unnecessarily costly for cold retention.
Question 94 An organization requires predictable offline operation when internet links fail. What cloud design lesson follows? Not every workload can depend exclusively on continuously reachable public services Buying an extra Azure subscription eliminates local connectivity outages Public cloud automatically works offline at every branch All local computing must stop when using any Azure service Explanation Correct Answer A:Connectivity constraints may justify local processing or a hybrid architecture. Incorrect Answers B:Administrative subscriptions do not replace network links. C:Cloud access depends on available connectivity. D:A hybrid design can retain critical local capability.
Question 95 A web app scales from one instance to many, yet users see slow first requests during sudden spikes. What limitation should the team consider? More instances remove every network latency regardless of location Assume autoscaling instantly makes a new instance warm without initialization time Provisioning and warm-up time can affect response to burst demand Autoscaling always adds capacity before any metric changes Explanation Correct Answer C:Scaling capacity may take time, so thresholds and prewarming can matter. Incorrect Answers A:Compute scale cannot eliminate geographic or network delays. B:Provisioning and application start-up can delay new capacity, so load response needs monitoring and design. D:Autoscaling reacts according to configured policies and platform behavior.
Question 96 Two Azure services exchange large volumes across different regions. What should be included in a cost estimate beyond the compute price? The date the Azure account was first created alone A guarantee that all Azure-internal traffic is free Only the number of user display names Potential inter-region data transfer charges Explanation Correct Answer D:Network movement between regions may have pricing implications. Incorrect Answers A:Account age does not quantify regional transfer usage. B:Some transfers are billed depending on route and service. C:Identity names are not a transfer cost metric.
Question 97 A system owner equates a published availability SLA with guaranteed perfect uptime for each application. What is the appropriate interpretation? An SLA defines conditional service targets, not zero application failure An SLA makes network failures physically impossible An SLA removes the need for backup and disaster recovery An SLA certifies the customer's source code as defect-free Explanation Correct Answer A:Tenant design, dependency health and provider terms all affect end-to-end reliability. Incorrect Answers B:Cloud services can still experience failures. C:Availability targets do not replace recovery planning. D:Provider commitments do not validate custom application logic.
Question 98 A team adds five replicas in the same outage-prone datacenter to handle more requests. Which risk remains unless the deployment separates failure domains? Customer access controls automatically disappear when scaling A resource group becomes a second region automatically A shared infrastructure failure can affect all replicas The workload cannot gain any throughput from the extra replicas Explanation Correct Answer C:Instance count alone does not protect replicas placed on the same failed infrastructure. Incorrect Answers A:Scaling does not inherently remove authentication. B:Logical grouping does not create geographic redundancy. D:More workers can increase throughput even if failure independence is missing.
Question 99 A company lifts a licensed operating system and commercial application to Azure VMs. Which cost item should it examine beyond core compute? Applicable software licensing and benefit eligibility Only the length of the VM hostname Only the Azure resource group's name An assumption that every third-party license is always included free Explanation Correct Answer A:VM pricing and license terms may vary by OS, image and existing entitlements. Incorrect Answers B:A hostname is not a software licensing unit. C:Grouping labels do not determine software license entitlements. D:Commercial licenses require checking product terms.
Question 100 A team replaces a self-managed database VM with a managed database service. What financial tradeoff should it assess? Compare only the two services’ hourly compute charges Assume managed services never charge for backup storage Managed service charges versus reduced operational maintenance effort Assume the original VM no longer costs anything while still running Explanation Correct Answer C:A platform fee can offset administrative labor and maintenance costs. Incorrect Answers A:A price-only comparison omits self-managed patching and administration time, which can offset managed-service fees. B:Backup and storage pricing can depend on configuration. D:Unremoved VMs remain billable.
