Question 570 A legacy server has been replicated into Azure as part of migration, and the team wants confidence before cutover. Which step remains necessary? Use billing tags as proof of application health Assume Azure Migrate automatically rewrites incompatible application code Delete the on-premises server before testing Test application functionality, connectivity and data correctness after the migration exercise Explanation Correct Answer D:Successful replication doesn't prove the workload behaves correctly in production. Incorrect Answers A:Cost metadata doesn't validate endpoints. B:Migration doesn't guarantee all code is portable. C:Immediate removal risks irreversible service interruption.
Question 571 A Linux analytics application requests POSIX-style shared file access. What should be checked before choosing an Azure Files share? Assume an SMB-only design always satisfies NFS clients unchanged Set the resource group name to NFS Choose Azure Queue Storage because messages look like files Supported protocol and tier compatibility for NFS Explanation Correct Answer D:Azure Files options differ by protocol, account configuration and availability. Incorrect Answers A:Protocol requirements cannot be ignored. B:Naming doesn't enable a protocol. C:Queue API isn't NFS.
Question 572 A client reads from a geo-redundant storage secondary endpoint and sees yesterday's update. What should the engineer explain? The blob access tier determines transaction ordering across regions RA-GRS guarantees zero secondary lag Secondary data can lag because geographic replication is asynchronous The client should recreate its Azure subscription Explanation Correct Answer C:Secondary reads can return older state until changes replicate. Incorrect Answers A:Tier is not the geo replication protocol. B:Read access doesn't make geo replication synchronous. D:Administrative accounts aren't the consistency issue.
Question 573 A disaster-recovery team plans to use geo-redundant storage after regional loss. What operational caveat should it investigate? Supported storage failover behavior, prerequisites and possible data loss window Ignore application reconnection behavior entirely Assume every storage account type supports identical failover choices Assume a failover never changes read/write endpoints or application connection behavior Explanation Correct Answer A:Geo redundancy doesn't mean every application transparently fails over with zero RPO. Incorrect Answers B:Clients still need to handle service recovery. C:Support depends on account and service options. D:Storage failover and client endpoint effects must be reviewed for the configured redundancy type.
Question 574 A team attaches labels to Blob objects to help organize searches, but needs an enforceable retention policy. Which distinction is important? Descriptive tags/metadata do not by themselves replace configured lifecycle or immutability controls Changing a label rehydrates archived data automatically Object metadata is a VM resource lock Any object tag automatically makes a blob undeletable Explanation Correct Answer A:Labels help classify objects; enforcement needs the appropriate storage feature. Incorrect Answers B:Metadata changes don't guarantee a tier transition. C:Object properties and ARM locks operate differently. D:Tagging is not WORM enforcement.
Question 575 A reporting application frequently downloads large Blob objects to an office outside Azure. Which cost factor must be estimated? Only the VM availability zone count Only an Azure subscription icon color Only the number of Blob container names Outbound data transfer and request charges under the chosen service and region Explanation Correct Answer D:Cross-boundary data movement can be a major bill component. Incorrect Answers A:Zone placement alone doesn't quantify Internet egress. B:UI colors aren't a usage metric. C:Names don't represent the volume transferred.
Question 576 A remote ingestion service sends many terabytes of data daily to Azure. Which deployment dimension could materially affect transfer time and data costs? Whether a subscription uses one management group The alphabetic ordering of storage containers The storage account friendly description Regional placement and network path between the source and storage account Explanation Correct Answer D:Geography and connectivity shape latency, throughput and applicable transfer charges. Incorrect Answers A:Governance hierarchy doesn't determine WAN physics. B:Naming order doesn't change bandwidth. C:Descriptions don't affect packet distance.
Question 577 A developer attempts to put a 200 MB video directly into a standard Azure Storage queue message. Which architecture is more suitable? Store the video in Blob Storage and enqueue a small reference Increase the queue name length to expand capacity Use Azure Queue Storage for the full large video byte stream rather than for a work notification Send the video in a VM OS boot sector Explanation Correct Answer A:Queue messages have size constraints and are intended for lightweight work descriptions. Incorrect Answers B:Queue names don't increase message-size limits. C:Queue messages have size limits and are better for references than storing a large media object payload. D:A guest boot disk isn't an application message transport.
Question 578 An application uses Azure Table Storage and assumes one transaction can atomically update arbitrary entities across unrelated partitions. Which design consideration matters? The resource group's billing tag determines transaction isolation Assume a single batch transaction can atomically update unrelated Azure Table Storage partitions Table transaction grouping is constrained by the service's supported partition scope Every Azure Table entity uses global cross-account ACID joins automatically Explanation Correct Answer C:Entity group transactions have partition and size rules that must be respected. Incorrect Answers A:Metadata tags don't change storage APIs. B:Entity-group transaction atomicity is constrained by partition and supported service rules. D:Table Storage isn't a global relational engine.
Question 579 A storage container has sensitive data, and an engineer proposes enabling anonymous public read access for convenience. Which risk should guide the decision? Making the URL longer is sufficient protection Using the Cool tier blocks anonymous access by definition Anonymous access means only Azure administrators can read files Public container access can expose objects without identity authorization Explanation Correct Answer D:A private or delegated access approach better matches sensitive data requirements. Incorrect Answers A:URL obscurity doesn't replace access controls. B:Access tiers don't implement the account's authorization model. C:Anonymous means unauthenticated clients may be able to retrieve data.
Question 580 A document was overwritten, and blob versioning was enabled before the change. What restoration approach should be investigated? Change a VM scale-set capacity rule Assume LRS alone keeps a browsable archive of every overwrite Select and restore the intended retained prior blob version Run an account-level DNS or network operation instead of recovering the retained blob version Explanation Correct Answer C:Versions can preserve earlier data independent of the current object's contents. Incorrect Answers A:Compute scaling doesn't retrieve previous Blob contents. B:Redundant current copies aren't version history. D:Network configuration cannot restore bytes from a previously stored blob version.
