Quick Answer

The answer is to change the 'sku.name' property from 'Standard_LRS' to 'Standard_GRS'. This is correct because the sku.name property directly controls the replication tier of an Azure Storage account; modifying it in the ARM template triggers an in-place update of the existing resource, converting it from locally redundant storage (LRS) to geo-redundant storage (GRS) without needing to add a secondary resource or alter the account kind. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this tests your understanding of declarative infrastructure updates versus imperative changes—a common trap is overcomplicating the fix by adding a separate geo-replication rule or changing the API version. Remember, when you need to modify Azure Storage replication from LRS to GRS using an ARM template, you only touch the sku.name property. Memory tip: “SKU is the key”—the SKU name dictates redundancy, so to go global, just change the label.

AZ-305 Design data storage solutions Practice Question

This AZ-305 practice question tests your understanding of design data storage solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

      }
    }
  ]
}

Refer to the exhibit. Your team deploys this ARM template to a resource group in West US. After deployment, you need to ensure the storage account is geo-redundant. What is the most efficient way to modify the template to achieve this?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Change the 'sku.name' property from 'Standard_LRS' to 'Standard_GRS'.

Option D is correct because changing the 'sku.name' property from 'Standard_LRS' to 'Standard_GRS' directly modifies the replication type of the existing storage account to geo-redundant storage (GRS). This is the most efficient approach as it updates the single resource in-place without adding extra resources or altering the storage account's kind or API version.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Add a second storage account resource with Geo-redundant replication.

    Why it's wrong here

    Unnecessary; you can modify the existing SKU.

  • ✗

    Change the 'kind' property to 'BlobStorage'.

    Why it's wrong here

    Kind determines storage type, not redundancy.

  • ✗

    Change the 'apiVersion' to a newer version.

    Why it's wrong here

    API version does not affect redundancy.

  • ✓

    Change the 'sku.name' property from 'Standard_LRS' to 'Standard_GRS'.

    Why this is correct

    Standard_GRS provides geo-redundant storage.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may think adding a new resource or changing the API version is necessary, but the most efficient way is to modify the existing resource's 'sku.name' property, which directly controls replication redundancy.

Detailed technical explanation

How to think about this question

Azure Storage replication levels are defined in the 'sku.name' property, where 'Standard_LRS' means locally redundant storage (LRS) and 'Standard_GRS' means geo-redundant storage (GRS). GRS replicates data to a paired secondary region, providing durability even during a regional outage. The ARM template's 'sku' object directly maps to the Azure Resource Manager API's 'Sku' property, and updating it triggers a configuration change on the existing storage account without downtime.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
