DP-900 Describe core data concepts Practice Question

This DP-900 practice question tests your understanding of describe core data concepts. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Exhibit

Refer to the exhibit.
```json
{
  "variables": {
    "storageAccountName": "[format('st{0}', uniqueString(resourceGroup().id))]"
  },
  "resources": [
    {
      "type": "Microsoft.Storage/storageAccounts",
      "apiVersion": "2023-01-01",
      "name": "[variables('storageAccountName')]",
      "location": "[resourceGroup().location]",
      "kind": "StorageV2",
      "sku": {
        "name": "Standard_LRS"
      },
      "properties": {
        "accessTier": "Hot",
        "supportsHttpsTrafficOnly": true
      }
    }
  ]
}
```

The exhibit shows an ARM template snippet for deploying an Azure storage account. What is the redundancy level of the storage account?

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

✓

Locally redundant storage (LRS)

The ARM template snippet does not specify a 'sku.tier' or 'sku.name' property that would indicate geo-replication or zone-redundancy. By default, when no redundancy option is explicitly configured, Azure Storage accounts deploy with Locally redundant storage (LRS), which replicates data three times within a single datacenter in the primary region.

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.

  • ✗

    Read-access geo-redundant storage (RA-GRS)

    Why it's wrong here

    RA-GRS would use Standard_RAGRS.

  • ✗

    Zone-redundant storage (ZRS)

    Why it's wrong here

    ZRS would use Standard_ZRS.

  • ✓

    Locally redundant storage (LRS)

    Why this is correct

    Standard_LRS indicates LRS.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Geo-redundant storage (GRS)

    Why it's wrong here

    GRS would use Standard_GRS.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume a storage account must have a redundancy level explicitly declared in the template, but Azure defaults to LRS when no 'sku' or 'redundancy' property is present, leading them to incorrectly select GRS or RA-GRS based on assumptions about geo-replication.

Detailed technical explanation

How to think about this question

Under the hood, the ARM template's 'resources[].properties' section for a storage account defaults to LRS when the 'sku' object is omitted or when 'sku.name' is not specified, as the Azure Resource Manager applies a default of 'Standard_LRS'. This behavior is defined in the Azure Storage REST API specification, where the 'SkuName' enum defaults to 'Standard_LRS' if not provided. In real-world scenarios, failing to explicitly set redundancy can lead to data loss during a datacenter-wide outage, as LRS does not protect against regional failures.

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.
