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 DBA needs to create a new Azure SQL Database and wants to ensure that the database automatically fails over to a secondary region without manual intervention. The recovery point objective (RPO) is 5 seconds. What should the DBA configure?
Explanation: Active geo-replication with a failover group is the correct choice because it provides automatic, customer-managed failover to a secondary region with an RPO of 5 seconds. The failover group orchestrates the failover of multiple databases simultaneously and supports automatic failover policies, meeting the requirement for zero manual intervention. Standard geo-replication does not support automatic failover, and other options do not provide cross-region disaster recovery.
You are planning a deployment of Azure SQL Database for a mission-critical application. The application requires a high level of resilience to regional failures. You need to ensure that data is replicated synchronously across two Azure regions and that automatic failover occurs with zero data loss. Which deployment option should you choose?
Explanation: SQL Server on Azure VMs with Always On Availability Groups can be configured with synchronous-commit mode across Azure regions, ensuring zero data loss (RPO=0) and automatic failover. In contrast, Azure SQL Database and Azure SQL Managed Instance only support asynchronous replication across regions via failover groups or geo-replication, which cannot guarantee zero data loss. General Purpose and Hyperscale tiers also lack synchronous cross-region replication.
You are designing a disaster recovery strategy for an Azure SQL Database in the West US region. The database is used by a mission-critical application with an RPO of 5 seconds and an RTO of 30 seconds. Which deployment option should you choose?
Explanation: Active geo-replication provides an asynchronous replica in a secondary region with an RPO of up to 5 seconds and supports manual failover with an RTO of approximately 30 seconds, meeting the strict RPO and RTO requirements for disaster recovery. Zone-redundant configuration (Option C) offers high availability within a single region but does not protect against regional outages, so it is not a disaster recovery solution. Failover groups (Option B and D) have an RTO of about 1 hour, exceeding the 30-second requirement. Therefore, Option A is correct.
You are configuring an Azure SQL Database elastic pool for a SaaS application. The pool will host 50 databases with varying workloads. You need to minimize cost while ensuring performance meets baseline requirements. Which tier and configuration should you choose?
Explanation: A DTU-based elastic pool offers a cost-effective solution for hosting 50 databases with varying workloads. DTU pools provide a shared resource model (eDTUs) that automatically balances capacity across databases, minimizing cost while meeting baseline performance requirements. Serverless tier (Option C) is not supported for elastic pools, making it invalid. Hyperscale (Option A) is designed for large, highly scalable databases and is overkill and costly. Provisioned vCore-based pool (Option B) with 2 vCores may be insufficient for 50 databases and is generally more expensive than DTU-based pools for variable workloads.
You are deploying a new Azure SQL Database that will be used by an application requiring high availability and automatic failover across Azure regions. The RPO must be less than 5 seconds, and the RTO must be less than 1 minute. You also need to ensure that the secondary region can be used for read-only workloads during normal operation. Which solution should you implement?
Explanation: Active geo-replication with a readable secondary in a different Azure region meets the requirements because it provides an asynchronous replication mechanism with an RPO of less than 5 seconds and an RTO of less than 1 minute during failover. The secondary database is fully readable for read-only workloads, supporting the application's need for read-scale in the secondary region during normal operation.
