Describe core data concepts →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct change is to set the SKU name to Standard_GRS, because Geo-Redundant Storage replicates your data synchronously three times within a primary region and then asynchronously to a secondary region hundreds of miles away, achieving the 11 nines of durability required for data that must be accessible from any Azure region. On the Microsoft Azure Data Fundamentals DP-900 exam, this question tests your ability to match redundancy options to business requirements—specifically distinguishing between LRS (single-datacenter durability) and GRS (cross-region durability). A common trap is choosing Premium_LRS for its performance, but that SKU is designed for low-latency workloads, not geo-accessibility. Remember: if the scenario demands access from any region and high durability, think “G” for global—GRS or RA-GRS. A quick memory tip: “GRS Gets Redundancy Spread” across regions.

DP-900 Describe core data concepts Practice Question

This DP-900 practice question tests your understanding of describe core data concepts. 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.

Correct answer & explanation

✓

Change the SKU name to Standard_GRS

Standard_GRS (Geo-Redundant Storage) is the correct SKU because it replicates data synchronously three times within a primary region and asynchronously to a secondary region hundreds of miles away, ensuring high durability (11 nines) and accessibility from any Azure region via read-access (RA-GRS). The requirement for data to be accessible from any Azure region and highly durable aligns with GRS's geo-replication, whereas LRS only replicates within a single datacenter and Premium_LRS is for low-latency workloads, not geo-accessibility.

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.

  • ✗

    Set supportsHttpsTrafficOnly to false

    Why it's wrong here

    Disabling HTTPS would weaken security and not affect durability.

  • ✗

    Change the SKU name to Premium_LRS

    Why it's wrong here

    Premium_LRS is for high-performance, not geo-replication.

  • ✓

    Change the SKU name to Standard_GRS

    Why this is correct

    Geo-redundant storage replicates data to a secondary region, improving durability across regions.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Change the kind to BlobStorage

    Why it's wrong here

    BlobStorage is a legacy kind; StorageV2 supports all features.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Microsoft often tests the misconception that changing the 'kind' (e.g., to BlobStorage) or disabling HTTPS affects durability or geo-accessibility, when in fact only the SKU name (replication strategy) controls these properties, and candidates confuse security settings with replication settings.

Detailed technical explanation

How to think about this question

Under the hood, Standard_GRS uses LRS in the primary region (three synchronous copies) plus asynchronous replication to a paired secondary region, where three additional copies are stored, achieving 16 nines of durability. A subtle behavior: by default, the secondary region is not directly accessible for reads unless you enable RA-GRS (Read-Access Geo-Redundant Storage), which is a separate property (supportsHttpsTrafficOnly is unrelated). In a real-world scenario, if a primary region goes down, GRS allows failover to the secondary region, but without RA-GRS, you must manually initiate a failover to make data accessible—this is a common oversight.

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.

Same concept, more angles

1 more ways this is tested on DP-900

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. The exhibit shows an ARM template snippet for deploying an Azure storage account. What is the redundancy level of the storage account?

hard
  • A.Read-access geo-redundant storage (RA-GRS)
  • B.Zone-redundant storage (ZRS)
  • ✓ C.Locally redundant storage (LRS)
  • D.Geo-redundant storage (GRS)

Why C: 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.
