Question 520 A VM hosts a SQL-like database needing a dedicated persistent block device. Which Azure storage construct is most direct? A Blob container as the guest's temporary disk Use Azure File Sync server endpoints as the VM's attached block device Azure Queue Storage An Azure managed disk attached as a data disk Explanation Correct Answer D:Managed disks present durable block storage to VMs. Incorrect Answers A:Object storage is not the VM's native managed block disk. B:File Sync manages supported shares, not VM virtual hard disks presented as block storage. C:Messages cannot be mounted as a database block device.
Question 521 An application has low-latency random I/O requirements on an attached Azure VM data disk. Which storage option deserves consideration? Azure Blob Archive as the VM's low-latency data disk A suitable premium managed disk tier and supported VM limits Azure Queue Storage with messages as database pages Choose the lowest-price Standard HDD disk regardless of workload IOPS requirements Explanation Correct Answer B:Disk performance tiers have IOPS/throughput characteristics relevant to random I/O. Incorrect Answers A:Archive is offline-oriented object storage, not a fast VM block disk. C:A queue isn't a block device. D:Standard HDD may fail demanding storage performance needs that require an appropriate managed disk tier.
Question 522 A developer needs Blob containers, Queue Storage, and Azure Files under compatible account services. What Azure resource is the entry point? A Microsoft Purview collection A suitable general-purpose Azure Storage account A VM availability set An Azure virtual network alone Explanation Correct Answer B:Account configuration provides supported storage services under one administrative resource. Incorrect Answers A:Catalog governance isn't a general-purpose storage account. C:VM placement doesn't offer object and queue APIs. D:Networking doesn't create Blob, file, and queue services.
Question 523 A partner asks which endpoint address is used to interact with an Azure Blob service. What address convention should the engineer inspect? A management-group policy assignment ID The storage account's Blob service endpoint over HTTPS A VM availability-set name A Windows guest desktop hostname unrelated to the account Explanation Correct Answer B:Blob APIs are exposed through a service-specific endpoint for the account. Incorrect Answers A:Policy governance isn't an HTTP object endpoint. C:Compute placement does not identify the Blob service address. D:A VM name isn't the Blob service endpoint.
Question 524 A design needs to choose how Azure keeps multiple copies of storage data. Which configuration is relevant? The storage account's supported redundancy option The number of tags on the account Change the default Blob access tier from Hot to Cool The default VM guest operating-system language Explanation Correct Answer A:LRS, ZRS and geo-redundant choices determine replica placement. Incorrect Answers B:Metadata tags do not define replica copies. C:Access tiers affect access economics, not the storage account’s configured replication and redundancy. D:Guest language doesn't select storage replicas.
Question 525 A small noncritical dataset can tolerate losing a single region and needs low-cost redundancy within one datacenter scope. Which model is relevant? Read-access geo-redundant storage (RA-GRS) Locally redundant storage (LRS) Geo-redundant storage (GRS) A CDN endpoint with no storage redundancy setting Explanation Correct Answer B:LRS replicates data within a single physical location in the primary region. Incorrect Answers A:RA-GRS adds a secondary read capability and more geographic redundancy. C:GRS adds copies to a paired secondary region, beyond the stated minimal scope. D:Content delivery caching doesn't replace durable storage replication.
Question 526 A business requires replicas of eligible storage data across multiple availability zones within its primary region. Which redundancy choice fits? Locally redundant storage (LRS) Geo-redundant storage (GRS) as a synonym for only local zones Zone-redundant storage (ZRS) A VM availability set Explanation Correct Answer C:ZRS spreads copies across distinct availability zones in the same region. Incorrect Answers A:LRS doesn't distribute copies across separate availability zones. B:GRS also involves a secondary region and differs from ZRS. D:Compute fault domains aren't the Blob storage replica policy.
Question 527 A company needs Azure Storage to maintain copies in a geographically separate secondary region for disaster scenarios. Which redundancy model supplies that? ZRS alone A resource lock LRS alone Geo-redundant storage (GRS) Explanation Correct Answer D:GRS asynchronously replicates eligible stored data from the primary to a secondary region. Incorrect Answers A:ZRS protects against local zone loss but not regional storage loss. B:Locks affect management operations, not cross-region storage replication. C:LRS copies remain within the primary local storage location.
Question 528 A reporting workload wants read access to a geo-redundant storage account's secondary endpoint before any failover, where supported. Which option is relevant? Read-access geo-redundant storage (RA-GRS) Plain LRS ZRS as a guarantee of secondary-region reads A new resource-group tag Explanation Correct Answer A:RA-GRS adds read access to the secondary replica of eligible geo-redundant storage. Incorrect Answers B:LRS has no remote secondary endpoint. C:ZRS is primary-region zone replication. D:Tags do not expose a geo secondary endpoint.
Question 529 A resilient service requires both multi-zone storage replicas in the primary region and copies in a secondary region. Which model should it consider? Plain LRS Geo-zone-redundant storage (GZRS), where available A VM scale set without storage redundancy ZRS without geographic replication Explanation Correct Answer B:GZRS combines primary-region zone resilience with geographic replication. Incorrect Answers A:LRS doesn't span multiple zones or regions. C:Compute scale doesn't define stored object replica geography. D:ZRS protects the primary region's zones only.
Question 530 A transaction system assumes GRS guarantees zero data loss if a region fails at the exact instant of a write. What should the architect clarify? GRS is always fully synchronous across regions Geo-replication is asynchronous and can have a nonzero recovery point RA-GRS eliminates every replication delay A storage account name length determines the recovery point Explanation Correct Answer B:The secondary may lag the latest committed primary writes. Incorrect Answers A:Cross-region storage replication has asynchronous behavior. C:Read access doesn't change propagation consistency. D:Naming isn't a replication lag policy.
