DP-300 validates the day-to-day skills of a database administrator running SQL workloads on Azure: deploying and configuring Azure SQL Database, Azure SQL Managed Instance, and SQL Server on Azure VMs; securing data; tuning performance; automating routine tasks; and engineering high availability and disaster recovery. The audience is working DBAs migrating from on-premises SQL Server to Azure, and cloud engineers picking up DBA responsibilities. The exam runs 50 questions in 120 minutes — longer than most associate exams — including drag-and-drops, scenario items, and case studies. Expect a heavy T-SQL component for tuning and security questions.
About 22%. Deployment options across Azure SQL Database, SQL MI, and SQL on VMs; provisioning, sizing, vCore vs. DTU, hyperscale, serverless tier, migrations with DMS / DMA, and IaC.
About 18%. Microsoft Entra authentication, RBAC, contained users, TDE, Always Encrypted, dynamic data masking, row-level security, auditing, and Microsoft Defender for SQL.
About 22%. Query Store, Intelligent Query Processing, automatic tuning, indexes (rowstore / columnstore), execution plans, blocking / deadlocks, and Azure-side metrics with Log Analytics.
About 18%. Elastic jobs, SQL Agent on MI / VM, Azure Automation runbooks, Logic Apps for ops, alerts, and PowerShell / Azure CLI scripting for DBA tasks.
About 20%. Active geo-replication, auto-failover groups, Always On AGs on VMs, backups (PITR, LTR), and RPO / RTO planning.
$95k–$130k–$175k USD annual
Range covers US-based mid-to-senior DBAs where Azure SQL proficiency is required. Senior data-platform engineers at FAANG / fintech often clear $200k TC. Non-coastal US markets and traditional enterprise DBAs trend lower; cloud-migration specialists trend higher.

DP-300 demand is steady, driven by ongoing migration of on-premises SQL Server estates onto Azure SQL Database and SQL Managed Instance — a multi-year enterprise trend. Recruiters use it as the canonical proof of Azure SQL operational competence. It pairs commonly with AZ-104 for cross-functional cloud admins, with DP-203 / DP-700 for engineers who span DBA and data-engineering work, and with DP-100 / DP-600 for data-platform generalists. Demand is especially strong in financial services, healthcare, government, and ISVs running heavy SQL Server estates.
There are no formal prerequisites. Microsoft recommends one to two years of database administration experience and working knowledge of T-SQL and SQL Server internals. Candidates without that background should plan extra study time. AZ-900 and DP-900 are useful conceptual on-ramps but not required.
The official Microsoft Learn path covers all five domains in roughly 35–45 hours, focused on Azure SQL family operations, security, and HA/DR. Hands-on lab time is essentially required: a personal Azure subscription with at least one Azure SQL DB, one SQL MI (or trial), and a SQL VM is ideal for practicing failovers, security configurations, and Query Store. Many candidates supplement with Microsoft's official practice assessment plus a third-party video course (Pluralsight, Udemy, Tutorials Dojo).
DP-300 sits in the Associate tier and is broadly considered moderately challenging — easier than AZ-204 for experienced DBAs, but harder than DP-900 by a wide margin. Plan on 70–110 hours of study over 7–10 weeks with prior SQL Server DBA background; substantially longer if SQL is new. The exam runs about 120 minutes — longer than typical associate exams — with 40–60 questions in multiple-choice, multiple-response, drag-and-drop, hot-area, and case-study formats. Case studies are timed separately and cannot be revisited once you move past them.
The most common stumbling block is the breadth across three deployment models — Azure SQL DB, SQL MI, and SQL on VMs each have different security, HA, and backup behavior, and the exam expects you to know which features apply where. T-SQL fluency for Always Encrypted, dynamic data masking, and row-level security examples is also frequently underestimated.
Most recent skills-measured update. Refreshed Microsoft Entra authentication coverage, expanded Hyperscale and serverless content, modernized Defender for SQL framing. Microsoft refreshes DP-300 approximately every 12–18 months without changing the exam code.
Restructured into the current five-domain layout, rebalanced weights toward security and automation, and renamed Azure AD references to Microsoft Entra ID.
Initial GA, replacing the retired Microsoft Database track exams. Original outline focused on Azure SQL DB and SQL MI day-to-day administration.
DP-300 (Microsoft Azure Database Administrator Associate) is a a moderately difficult exam expecting practical hands-on experience plus solid understanding of best practices Associate-level exam. Most candidates need 80–150 hours of study spread over 6–12 weeks for associate-level exams. Most candidates who score consistently above the passing threshold on practice exams pass on their first attempt.
