Question 40 A business asks whether stored objects can survive hardware loss, independently of whether a web application stays reachable. Which property is being evaluated? Application responsiveness at peak request rate Interactive user sign-in latency Data durability A software subscription's monthly cost Explanation Correct Answer C:Durability concerns preservation of stored information over time despite component failures. Incorrect Answers A:Throughput is different from preservation of stored bytes. B:Authentication performance does not measure data survival. D:Price alone does not establish the probability of data retention.
Question 41 An object storage service stores every file redundantly, but a network outage temporarily prevents users from reading it. Which distinction is important? Data can remain durable while temporarily unavailable Data redundancy guarantees every request succeeds instantly Temporary unavailability proves all stored bytes are lost Only storage price determines file durability Explanation Correct Answer A:Durability is not identical to continuous accessibility. Incorrect Answers B:Network and service failures can still affect access. C:An access outage does not by itself imply data loss. D:Redundancy architecture, not only price, controls durability.
Question 42 A manager asks what a cloud service's availability SLA typically expresses. Which answer is most accurate? A promise that all customer applications can never have bugs A contractual service availability commitment with defined conditions A requirement to buy physical hardware before using Azure A guarantee that every storage write is permanently free Explanation Correct Answer B:An SLA describes availability targets and eligible remedies, not an absolute no-outage guarantee. Incorrect Answers A:Provider availability does not eliminate tenant application errors. C:Cloud services can be provisioned without owning the datacenter. D:SLAs concern service commitments, not universal pricing.
Question 43 A hosted service misses its published monthly availability commitment. What should the customer check rather than assume damages are automatically paid? Assume any outage automatically qualifies for an unlimited cash refund Assume every minute of degraded application performance is covered by the infrastructure SLA The application source code line count The SLA's measurement rules and eligible service credit process Explanation Correct Answer D:Remedies normally depend on the specific terms and claim procedures. Incorrect Answers A:Microsoft service credits depend on the published SLA, scope, measurement and request process, rather than unlimited damages. B:An infrastructure SLA may use narrower measurements and exclusions than application end-to-end responsiveness. C:Code length does not determine eligibility for a provider availability credit.
Question 44 A team deploys its service only on one VM and asks how to reduce dependence on that machine. Which change is most relevant? Increase the disk name length Keep a second password for the same VM Use redundant instances across appropriate failure domains Turn off monitoring to avoid false alarms Explanation Correct Answer C:Separating replicas lowers reliance on any single instance or host. Incorrect Answers A:Naming does not create extra capacity or fault tolerance. B:Credentials do not create compute redundancy. D:Suppressing telemetry cannot improve continuity.
Question 45 A data team wants more consistent workload response times instead of merely maximizing peak throughput. Which activity best supports performance predictability? Benchmark representative demand and select suitable scaling capacity Assume any smallest VM delivers identical latency to the largest Buy a fixed server without observing application demand Disable metrics during test runs Explanation Correct Answer A:Measuring realistic load and sizing resources reduces surprises under expected traffic. Incorrect Answers B:Hardware size can materially affect performance. C:Capacity guesses do not establish predictable performance. D:Without measurements, the team cannot evaluate consistency.
Question 46 Finance needs a cloud budget estimate for a service that uses VMs, storage and outbound transfer. Which practice is most defensible? Budget solely from the number of developers Estimate each service's expected usage and validate ongoing spend Ignore operating hours because VM state cannot affect charges Assume inter-region data transfer is always free Explanation Correct Answer B:Cloud predictability comes from usage assumptions, pricing models and monitoring. Incorrect Answers A:Developer headcount does not capture resource usage. C:Resource runtime can materially affect compute charges. D:Transfer patterns can contribute to the bill.
Question 47 A project director argues that cloud redundancy eliminates the need for access control. What is the correct distinction? Redundancy supports continuity, while identity and permissions control access Availability zones grant every employee administrative rights A duplicate storage copy automatically authenticates all users Backups eliminate all risks from stolen credentials Explanation Correct Answer A:Copies of data do not decide who should read or modify it. Incorrect Answers B:Zones are infrastructure locations rather than permission grants. C:Redundancy is not an identity provider. D:Data copies do not prevent misuse of an authorized account.
Question 48 A tenant has configured a secure virtual network but a physical router fails inside Microsoft's facility. Which party maintains that physical routing hardware? Assume the tenant can log in to maintain Azure's physical routers The tenant must replace the router in the provider's rack Microsoft manages the datacenter's physical network infrastructure An application end user replaces the hardware Explanation Correct Answer C:The platform provider repairs underlying network devices while the tenant manages its virtual configuration. Incorrect Answers A:The provider operates physical datacenter networking; tenant responsibility lies in its configured network rules and workloads. B:The tenant does not own or maintain the provider's physical fabric. D:End users cannot maintain the provider's underlying networking equipment.
Question 49 An Azure VM is reachable from the internet because its network security rules permit a broad inbound port. Who should correct the customer's overly permissive rule? The provider's datacenter electrician The Azure customer who controls its network policy Another Azure tenant in the same region Assign the cloud provider responsibility for every tenant NSG rule Explanation Correct Answer B:The tenant configures its virtual network security and is responsible for inappropriate exposure. Incorrect Answers A:Facility staff do not choose the customer's network security rules. C:Unrelated tenants have no authority to set this organization's access rules. D:Provider security of the infrastructure does not replace the customer's virtual network filtering configuration.
Question 50 A VM operator grants every employee the same administrative sign-in credentials. What shared-responsibility error has occurred? Physical datacenter access policies automatically restrict guest accounts The virtualization hardware must be replaced to change login rights The customer failed to manage identity and privileges appropriately Microsoft must publish every employee's password Explanation Correct Answer C:Cloud hosting does not relieve the tenant of controlling who can administer its VMs. Incorrect Answers A:Facility controls cannot replace tenant guest and account permissions. B:Identity policy can be corrected without changing physical hosts. D:The provider does not own the organization's privileged identities.
