  2. Question 2Design data storage solutions

    An architect designs a data warehouse loading strategy. The company has 5 TB of data in Azure Data Lake Storage Gen2 and needs to load it into Azure Synapse dedicated SQL pool efficiently. Which loading method is most efficient?

    AINSERT statements from ADF
    BCOPY INTO statement or PolyBase with external tables for parallel bulk loading
    CBCP utility
    DAzure DMS for Synapse loading

  3. Question 3Design data storage solutions

    A company needs to implement a solution where operational Azure SQL Database data is available in Azure Synapse Analytics for analytics queries without ETL pipelines. Which Azure feature enables this?

    AAzure Data Factory incremental copy
    BAzure Synapse Link for Azure SQL Database (near-real-time analytical replication with no ETL)
    CActive geo-replication to a Synapse dedicated pool
    DSQL Database elastic query for cross-database queries

  4. Question 4Design data storage solutions

    An architect must design a solution where multiple Azure services (ADF, Synapse, AML) need to read from an ADLS Gen2 storage account without each service having its own storage key. What is the recommended identity approach?

    AStore the storage account key in Key Vault and share it across services
    BAssign each service a Managed Identity and grant each identity the appropriate RBAC role (e.g., Storage Blob Data Reader/Contributor) on the ADLS account
    CCreate a shared service principal and share its credentials
    DUse a SAS token with a long expiry

AZ-305 Data Storage Exam Tips

Data Storage Solutions questions in AZ-305 are typically scenario-based. Focus on solution architecture design, resilience, governance, and data platform trade-offs. Priority concepts: sql database, cosmos db, data lake, storage account, synapse, data factory.

What AZ-305 Expects

  • Anchor your answer in select architecture decisions that balance business continuity, performance, and governance.
  • Data Storage scenarios for AZ-305 are frequently mapped to Domain 2 (25-30%), so read the objective carefully before picking controls or architecture.
  • Expect multi-topic scenarios where Data Storage interacts with identity, networking, governance, or monitoring patterns rather than appearing as an isolated question.
  • When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Expert) and vendor best practices.

High-Value Data Storage Concepts

  • Know the core Data Storage building blocks cold: sql database, cosmos db, data lake, storage account.
  • Review the edge-case features and limits for synapse, data factory; these details are commonly used to differentiate answer choices.
  • Practice service-integration reasoning: how Data Storage pairs with Business Continuity, Compute in real deployment patterns.
  • For AZ-305, explain why the chosen Data Storage design meets reliability, security, and cost expectations better than the alternatives.

Common AZ-305 Traps

  • Watch for designing for feature completeness but not for resilience.
  • Questions in Design Data Storage Solutions often include distractors that look correct for Data Storage but violate least-privilege, compliance, or availability requirements.
  • Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
  • If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.

Fast Review Checklist

  • Can you compare at least two Data Storage implementation paths and justify which one best fits the scenario?
  • Can you map the chosen answer back to Design Data Storage Solutions (25-30%) outcomes for AZ-305?
  • Can you explain security and access boundaries for Data Storage without relying on default-open assumptions?
  • Can you describe how Data Storage integrates with Business Continuity and Compute during failure, scaling, and monitoring events?
