20+ practice questions focused on Plan and implement data platform resources — one of the most tested topics on the Microsoft Azure Database Administrator Associate DP-300 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Plan and implement data platform resources PracticeA company is deploying Azure SQL Managed Instance and needs to ensure that the failover group provides automatic failover with zero data loss during a regional outage. The secondary region is 500 miles away. Which data replication mode should be configured?
Explanation: Azure SQL Managed Instance failover groups require synchronous replication to guarantee zero data loss during automatic failover. Synchronous replication ensures that transactions are committed on both the primary and secondary replicas before acknowledging the commit, so no data is lost even if the primary region fails. This mode is mandatory for failover groups with the 'automatic failover' and 'zero data loss' requirements, despite the 500-mile distance which introduces latency.
A retail company is migrating its on-premises SQL Server database to Azure SQL Database. The database has a table with 500 million rows and receives 10,000 INSERT operations per second during peak hours. The application requires read-committed snapshot isolation. Which Azure SQL Database tier and configuration should the DBA recommend to minimize cost while meeting performance requirements?
Explanation: The Hyperscale tier with 4 vCores is correct because it supports up to 100 TB of storage, provides fast scaling for high-volume INSERT workloads (10,000 rows/second), and natively supports read-committed snapshot isolation (RCSI) without additional configuration. It minimizes cost compared to Business Critical while offering the necessary performance and isolation level for a 500-million-row table.
A company has an Azure SQL Managed Instance that is experiencing high CPU usage. The DBA observes that a specific query is causing high compile time due to parameter sniffing. The query is executed frequently with varying parameter values. Which approach should the DBA use to reduce CPU usage without changing the T-SQL code?
Explanation: Forced parameterization (Option D) converts literal values in the query to parameters, allowing SQL Server to reuse cached execution plans across different parameter values. This reduces CPU usage by eliminating frequent recompilations caused by parameter sniffing, without requiring any changes to the T-SQL code itself.
A DBA is migrating a large on-premises database to Azure SQL Database using the Data Migration Assistant (DMA). The migration fails with an error indicating that the source database contains cross-database queries. What is the best remediation?
Explanation: Azure SQL Database does not support cross-database queries natively. The Data Migration Assistant (DMA) blocks migrations that rely on such queries because the PaaS service lacks the necessary server-level context. The correct remediation is to refactor the application to eliminate cross-database dependencies or use elastic query, which provides a read-only, schema-bound mechanism to query remote databases via external data sources and external tables.
A company plans to deploy Azure SQL Database in a new region. They require that the database be accessible only from a specific set of Azure virtual machines in the same region. What should the DBA configure?
Explanation: A VNet service endpoint extends your virtual network private address space and the identity of your VNet to the Azure SQL Database service over a direct connection. By combining a service endpoint on the subnet with a firewall rule that allows traffic only from that specific VNet/subnet, you restrict access exclusively to Azure VMs in that subnet, meeting the requirement without exposing the database to the public internet.
