Question 80 An analytics design continuously moves large data volumes between a local datacenter and Azure. Which practical factor must be evaluated? Guaranteed unlimited bandwidth without network design Plan for peak transfer volume but ignore data egress and networking meter rates The assumption that all sites share the same local memory Connectivity throughput, latency and transfer charges Explanation Correct Answer D:Hybrid designs depend on network capacity and may incur movement costs. Incorrect Answers A:Links have capacity and performance constraints. B:A link may handle throughput while still generating material transfer charges. C:Separate environments communicate over networks.
Question 81 An organization cannot migrate all systems at once and wants some services on premises during a phased move to Azure. What strategy accommodates this? Shut off every local service before evaluating cloud replacements Hybrid coexistence during migration Purchase a cloud license without deploying any connectivity Use only an offline desktop backup as the production service Explanation Correct Answer B:A hybrid arrangement lets hosted and local systems operate together while dependencies are changed. Incorrect Answers A:An all-at-once shutdown conflicts with phased continuity. C:A license alone does not create system coexistence. D:A backup file is not a staged application architecture.
Question 82 A company deploys IaaS and asks whether it must guard the entrance to Azure's datacenter. What is accurate? The provider maintains the facility's physical security The customer must hire guards at each Azure facility All Azure resource owners become building security contractors Physical security is unnecessary in cloud computing Explanation Correct Answer A:Azure is responsible for its datacenter security while the tenant handles its resources and identities. Incorrect Answers B:Public cloud customers do not manage provider facility entrances. C:Logical resource ownership does not confer facility operations. D:The provider still needs physical safeguards.
Question 83 An organization uses IaaS VMs and assumes Azure automatically makes every application-consistent restore point forever. What should it understand? Provider-owned servers imply unlimited guest application backups The tenant must design and configure suitable backup and retention for its workloads VM snapshots are never relevant to backup design Assume the application provider always retains every deleted tenant record indefinitely Explanation Correct Answer B:Managed infrastructure does not promise perpetual application-consistent recovery by default. Incorrect Answers A:Hosting and backup configurations are separate responsibilities. C:Snapshots can be useful but require appropriate design and retention. D:SaaS availability and provider backups do not remove the organization's responsibility to evaluate retention and recovery needs.
Question 84 A customer must decide whether to use additional customer-managed encryption keys for sensitive cloud data. Who owns that business decision? Every unrelated tenant in the shared datacenter The internet routing provider alone The region's power utility The customer, based on its security and compliance requirements Explanation Correct Answer D:Provider encryption capabilities do not determine the tenant's governance mandate. Incorrect Answers A:Other tenants do not set this organization's policy. B:Network transport does not decide data governance key requirements. C:Utility services are unrelated to encryption policy.
Question 85 A team moves a regulated application from a local VM to a managed platform but keeps the same data sensitivity. What remains true? All data-access decisions transfer to the provider automatically No logging is ever needed because the host is managed Existing legal obligations cease when servers are hosted The organization must still govern data access, classification and retention Explanation Correct Answer D:The managed runtime changes infrastructure duties but not business data accountability. Incorrect Answers A:Tenants retain responsibility for authorized principals and records. B:Tenant observability and compliance evidence remain relevant. C:Compliance does not disappear through cloud migration.
Question 86 A function receives a large burst of independent events. Which platform behavior is a benefit of suitable serverless hosting? A single local laptop always processes every event Execution capacity can scale to process additional independent invocations Every invocation is guaranteed unlimited memory and duration The developer must provision a physical server before each invocation Explanation Correct Answer B:The platform manages function instances subject to plan quotas and scaling constraints. Incorrect Answers A:Laptop-bound compute lacks elastic hosted execution. C:Execution plans impose limits and resource policies. D:Serverless platforms abstract physical capacity acquisition.
Question 87 A website scales from three instances to ten for a short marketing event. Which factor affects consumption cost? How many instances run and for how long The belief that autoscaled capacity is always free The order in which developers named the instances The number of marketing slides prepared for the launch Explanation Correct Answer A:Additional allocated compute increases metered instance time. Incorrect Answers B:Elastic resources generally remain chargeable as used. C:Resource naming is not the billed usage unit. D:Presentation material does not consume the web-serving compute by itself.
Question 88 A batch job completes twice as fast on a much larger VM but uses significantly higher hourly charges. Which comparison is most meaningful? Total cost per completed job at required performance Only wall-clock duration without billed rate Only the Azure portal's resource name Only the largest VM's CPU count Explanation Correct Answer A:A faster machine may or may not be cheaper once time and rate are combined. Incorrect Answers B:Runtime must be combined with charge rate to compare spending. C:Names do not show compute cost effectiveness. D:Compute size alone does not establish workload economics.
Question 89 A hosted application returns errors because a developer deployed invalid configuration, although the cloud platform is healthy. Which party should correct the configuration? The physical rack manufacturer alone The application-owning team A separate customer's infrastructure administrator Assume the customer has no responsibility for any application configuration after cloud migration Explanation Correct Answer B:Provider platform availability cannot compensate for a tenant's invalid application settings. Incorrect Answers A:The problem is application configuration, not an identified hardware failure. C:Other tenants cannot repair the organization's configuration. D:Cloud providers secure the platform, but tenant permissions and application controls still need customer management.
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.
