Question 540

A storage account must keep data available after some local hardware fails. The team observes: Stakeholders assume local replication covers a whole regional outage. What is the most likely cause of the observed failure?

  1. It selected a NoSQL table model without matching query needs.
  2. It misunderstood GRS secondary read-access behavior.
  3. LRS scope was confused with cross-region resilience.
  4. It skipped the discovery/assessment stage before migration.

Explanation

Correct Answer

C:

LRS scope was confused with cross-region resilience. That explains the symptom: Stakeholders assume local replication covers a whole regional outage. The targeted corrective action is: Set LRS redundancy on the supported storage account.

Incorrect Answers

A:

This cause is consistent with a different issue: The team expects SQL joins from a simple table entity store. It does not account for the reported symptom here: Stakeholders assume local replication covers a whole regional outage.

B:

The alternate mechanism would more directly produce this other failure: The project expects access to secondary storage before failover without RA-GRS. The current incident instead involves: Stakeholders assume local replication covers a whole regional outage.

D:

This cause is consistent with a different issue: A team moves servers without collecting compatibility or sizing data. It does not account for the reported symptom here: Stakeholders assume local replication covers a whole regional outage.

Question 541

A regional service wants storage replication across availability zones within the primary region. Which architectural decision meets the described priority?

  1. Choose Azure Blob Storage for object data rather than a shared file system.
  2. Use Azure Managed Disks for VM disk volumes.
  3. Select Azure Files as a managed file share service.
  4. Consider ZRS where the region and storage service support it.

Explanation

Correct Answer

D:

Consider ZRS where the region and storage service support it. The governing requirement is: A regional service wants storage replication across availability zones within the primary region. This solution specifically supports the outcome that data redundancy spans supported zones in the same Azure region.

Incorrect Answers

A:

This design is appropriate for a different requirement: A photo app stores large unstructured images that must be accessed over HTTPS. Here the decisive outcome must instead be: Data redundancy spans supported zones in the same Azure region.

B:

That concept addresses this separate situation: A VM's operating-system disk must persist across restarts and be managed as block storage. It does not by itself establish the result required here: Data redundancy spans supported zones in the same Azure region.

C:

This option solves a different planning problem: A legacy file share application needs a managed SMB share accessible by supported clients. The current acceptance criterion is specific: Data redundancy spans supported zones in the same Azure region.

Question 542

A regional service wants storage replication across availability zones within the primary region. Which configuration or operating action most directly puts that decision into practice?

  1. Create an Azure file share and authorize appropriate client access.
  2. Create a supported table and use partition/row keys for entities.
  3. Select ZRS for the eligible account and validate zone support.
  4. Order and prepare Data Box devices according to approved transfer procedures.

Explanation

Correct Answer

C:

Select ZRS for the eligible account and validate zone support. The implementation operationalizes this design choice: Consider ZRS where the region and storage service support it. Acceptance should demonstrate: Data redundancy spans supported zones in the same Azure region.

Incorrect Answers

A:

This setup is relevant to another workload: A legacy file share application needs a managed SMB share accessible by supported clients. The current configuration must instead achieve: Data redundancy spans supported zones in the same Azure region.

B:

That action implements a different requirement: An inventory system stores simple key-value records with flexible schemas and low-cost NoSQL access. It does not establish the required result in this case: Data redundancy spans supported zones in the same Azure region.

D:

This setup is relevant to another workload: A data center must transfer petabytes to Azure but its internet link is too slow. The current configuration must instead achieve: Data redundancy spans supported zones in the same Azure region.

Question 543

A regional service wants storage replication across availability zones within the primary region. Which observation is the strongest acceptance test for this scenario?

  1. Data remains available after an eligible local replica/device failure.
  2. The inventory and readiness report identify migration risks.
  3. Data redundancy spans supported zones in the same Azure region.
  4. The account has a geo-replicated secondary copy under the service model.

Explanation

Correct Answer

C:

Data redundancy spans supported zones in the same Azure region. That directly tests the stated requirement: A regional service wants storage replication across availability zones within the primary region. It contrasts with the observed failure: All replicas remain tied to one zone despite zone-failure requirements.

Incorrect Answers

A:

This observation is evidence for a separate scenario: A storage account must keep data available after some local hardware fails. It does not test the necessary outcome here: Data redundancy spans supported zones in the same Azure region.

B:

That check tests another control: A company wants discovery and assessment before moving existing on-premises servers. The decisive result for this workload is: Data redundancy spans supported zones in the same Azure region.

D:

This observation is evidence for a separate scenario: A business needs cross-region storage protection with an asynchronous secondary copy. It does not test the necessary outcome here: Data redundancy spans supported zones in the same Azure region.

Question 544

A regional service wants storage replication across availability zones within the primary region. The team observes: All replicas remain tied to one zone despite zone-failure requirements. Which planning or configuration error best accounts for this result?

  1. LRS was chosen where zonal redundancy was required.
  2. The persistent VM disk requirement was not mapped to managed block storage.
  3. It misunderstood GRS secondary read-access behavior.
  4. Object storage was mistaken for a file-share interface.

Explanation

Correct Answer

A:

LRS was chosen where zonal redundancy was required. That explains the symptom: All replicas remain tied to one zone despite zone-failure requirements. The targeted corrective action is: Select ZRS for the eligible account and validate zone support.

Incorrect Answers

B:

The alternate mechanism would more directly produce this other failure: Guest data disappears because the wrong temporary storage was used. The current incident instead involves: All replicas remain tied to one zone despite zone-failure requirements.

C:

That explanation belongs to a different fault pattern: The project expects access to secondary storage before failover without RA-GRS. It does not explain why all replicas remain tied to one zone despite zone-failure requirements.

D:

This cause is consistent with a different issue: Users are given only a blob container URL when they need an SMB mount. It does not account for the reported symptom here: All replicas remain tied to one zone despite zone-failure requirements.

Question 545

A business needs cross-region storage protection with an asynchronous secondary copy. Which Azure or cloud concept most directly matches the requirement?

  1. Select an appropriate cooler Blob access tier according to retrieval expectations.
  2. Evaluate GZRS or RA-GZRS according to secondary read requirements and region support.
  3. Choose GRS if geographic redundancy and its read limits match requirements.
  4. Consider Blob Archive tier where latency and rehydration constraints fit.

Explanation

Correct Answer

C:

Choose GRS if geographic redundancy and its read limits match requirements. The governing requirement is: A business needs cross-region storage protection with an asynchronous secondary copy. This solution specifically supports the outcome that the account has a geo-replicated secondary copy under the service model.

Incorrect Answers

A:

This design is appropriate for a different requirement: A website rarely accesses old log archives but needs low storage cost. Here the decisive outcome must instead be: The account has a geo-replicated secondary copy under the service model.

B:

That concept addresses this separate situation: A backup workload needs zone protection in its primary region plus geo-replication. It does not by itself establish the result required here: The account has a geo-replicated secondary copy under the service model.

D:

This design is appropriate for a different requirement: A legal organization must preserve documents that are almost never read for years. Here the decisive outcome must instead be: The account has a geo-replicated secondary copy under the service model.

Question 546

A business needs cross-region storage protection with an asynchronous secondary copy. Which implementation step would best fulfill the stated requirement?

  1. Select the supported GRS redundancy option for the storage account.
  2. Register and configure the local server and Azure file share endpoints.
  3. Move eligible retained objects to Archive with documented retrieval procedure.
  4. Configure hot access for the current image container or eligible objects.

Explanation

Correct Answer

A:

Select the supported GRS redundancy option for the storage account. The implementation operationalizes this design choice: Choose GRS if geographic redundancy and its read limits match requirements. Acceptance should demonstrate: The account has a geo-replicated secondary copy under the service model.

Incorrect Answers

B:

That action implements a different requirement: An engineer wants to synchronize files from a Windows server to an Azure file share. It does not establish the required result in this case: The account has a geo-replicated secondary copy under the service model.

C:

This change would be appropriate under a different condition: A legal organization must preserve documents that are almost never read for years. Here it would not validate: The account has a geo-replicated secondary copy under the service model.

D:

This setup is relevant to another workload: An e-commerce catalog contains frequently viewed images that need low-latency retrieval. The current configuration must instead achieve: The account has a geo-replicated secondary copy under the service model.

Question 547

A business needs cross-region storage protection with an asynchronous secondary copy. Which result would best demonstrate successful implementation?

  1. Applications use the correct SMB/NFS or object interface for their needs.
  2. Data redundancy spans supported zones in the same Azure region.
  3. The account has a geo-replicated secondary copy under the service model.
  4. Records can be retrieved using their expected entity keys.

Explanation

Correct Answer

C:

The account has a geo-replicated secondary copy under the service model. That directly tests the stated requirement: A business needs cross-region storage protection with an asynchronous secondary copy. It contrasts with the observed failure: The project expects access to secondary storage before failover without RA-GRS.

Incorrect Answers

A:

This observation is evidence for a separate scenario: A storage team wants to describe the difference between Azure Files and Blob Storage. It does not test the necessary outcome here: The account has a geo-replicated secondary copy under the service model.

B:

That check tests another control: A regional service wants storage replication across availability zones within the primary region. The decisive result for this workload is: The account has a geo-replicated secondary copy under the service model.

D:

This observation is evidence for a separate scenario: An inventory system stores simple key-value records with flexible schemas and low-cost NoSQL access. It does not test the necessary outcome here: The account has a geo-replicated secondary copy under the service model.

Question 548

A business needs cross-region storage protection with an asynchronous secondary copy. The team observes: The project expects access to secondary storage before failover without RA-GRS. What should the team identify as the primary mechanism behind the problem?

  1. LRS was chosen where zonal redundancy was required.
  2. The storage service type does not provide the required object interface.
  3. It misunderstood GRS secondary read-access behavior.
  4. Object storage was mistaken for a file-share interface.

Explanation

Correct Answer

C:

It misunderstood GRS secondary read-access behavior. That explains the symptom: The project expects access to secondary storage before failover without RA-GRS. The targeted corrective action is: Select the supported GRS redundancy option for the storage account.

Incorrect Answers

A:

This cause is consistent with a different issue: All replicas remain tied to one zone despite zone-failure requirements. It does not account for the reported symptom here: The project expects access to secondary storage before failover without RA-GRS.

B:

The alternate mechanism would more directly produce this other failure: The application expects object URLs but the design provisioned only VM block disks. The current incident instead involves: The project expects access to secondary storage before failover without RA-GRS.

D:

This cause is consistent with a different issue: Users are given only a blob container URL when they need an SMB mount. It does not account for the reported symptom here: The project expects access to secondary storage before failover without RA-GRS.

Question 549

An analyst must read from a storage account's geo-secondary before failover. Which design choice best fits the stated business constraint?

  1. Use AzCopy for command-line data transfers at scale.
  2. Select RA-GRS when secondary-region read access is required and supported.
  3. Choose an eligible Azure Data Box offline transfer workflow.
  4. Evaluate GZRS or RA-GZRS according to secondary read requirements and region support.

Explanation

Correct Answer

B:

Select RA-GRS when secondary-region read access is required and supported. The governing requirement is: An analyst must read from a storage account's geo-secondary before failover. This solution specifically supports the outcome that authorized read requests to the secondary endpoint succeed as permitted.

Incorrect Answers

A:

This design is appropriate for a different requirement: A script must copy a large set of blobs between authorized storage accounts. Here the decisive outcome must instead be: Authorized read requests to the secondary endpoint succeed as permitted.

C:

This option solves a different planning problem: A data center must transfer petabytes to Azure but its internet link is too slow. The current acceptance criterion is specific: Authorized read requests to the secondary endpoint succeed as permitted.

D:

This design is appropriate for a different requirement: A backup workload needs zone protection in its primary region plus geo-replication. Here the decisive outcome must instead be: Authorized read requests to the secondary endpoint succeed as permitted.

Question 550

An analyst must read from a storage account's geo-secondary before failover. Which Azure setup action best follows from this scenario?

  1. Register discovery sources and review Azure Migrate assessment results.
  2. Choose RA-GRS rather than GRS for the eligible account.
  3. Run authenticated AzCopy commands between approved endpoints.
  4. Order and prepare Data Box devices according to approved transfer procedures.

Explanation

Correct Answer

B:

Choose RA-GRS rather than GRS for the eligible account. The implementation operationalizes this design choice: Select RA-GRS when secondary-region read access is required and supported. Acceptance should demonstrate: Authorized read requests to the secondary endpoint succeed as permitted.

Incorrect Answers

A:

This setup is relevant to another workload: A company wants discovery and assessment before moving existing on-premises servers. The current configuration must instead achieve: Authorized read requests to the secondary endpoint succeed as permitted.

C:

This change would be appropriate under a different condition: A script must copy a large set of blobs between authorized storage accounts. Here it would not validate: Authorized read requests to the secondary endpoint succeed as permitted.

D:

This setup is relevant to another workload: A data center must transfer petabytes to Azure but its internet link is too slow. The current configuration must instead achieve: Authorized read requests to the secondary endpoint succeed as permitted.
