DP-300 vs AZ-104: Which Azure Certification Fits Your Job?

DP-300 vs AZ-104 comes down to what you administer: databases or everything else. DP-300 (Administering Microsoft Azure SQL Solutions) earns the Azure Database Administrator Associate certification and tests running SQL workloads: security, performance tuning, automation and disaster recovery. AZ-104 (Microsoft Azure Administrator) earns the Azure Administrator Associate certification and tests the general cloud estate: identities, storage, compute, networking and monitoring. Both are associate-level, both require a 700 scaled score, both give you 100 minutes, and neither has formal prerequisites. If your job title contains the letters DBA, take DP-300. If you run the subscription the DBA works in, take AZ-104.

That heuristic settles most cases. The interesting decisions live in the overlap, so here is the full comparison.

DP-300 vs AZ-104 side by side

What each exam is really about

DP-300 is an operations exam wearing a deployment name. Provisioning resources is its smallest domain at 15 to 20 percent, while implementing security, monitoring and optimizing performance, and planning high availability and disaster recovery each carry 20 to 25 percent. You are expected to read execution plans, resolve session blocking with DMVs, pick between geo-replication, failover groups, availability groups and log shipping against stated RPO and RTO targets, and do several of these things in T-SQL rather than the portal. The domain-by-domain detail is on our DP-300 practice test page.

AZ-104 is the broadest of Microsoft's associate exams. Nothing in it goes as deep as DP-300's tuning objectives, but it spans the whole platform: dynamic groups and RBAC scope, storage account security, ARM templates and Bicep, Azure Container Apps, load balancers and DNS, Network Watcher and Azure Backup vaults. Candidates fail it on breadth. Our AZ-104 practice test page breaks down the five domains and the myths about them.

The overlap, and where the jobs diverge

Both exams touch Entra ID authentication, monitoring and backup, so studying one gives you a head start on maybe 15 percent of the other. But the daily jobs diverge sharply. The Azure administrator owns the subscription: cost, access, network paths, patching. The database administrator owns the data tier inside it: query latency, encryption at the column level, the restore that has to work at 3 a.m. In larger data teams that DBA role increasingly sits alongside analytics engineers and pipeline owners, where warehouse-level data lineage and observability tooling covers the estate the DBA tunes one database at a time.

A useful tiebreaker question: when something is slow, which layer do you instinctively open first? If it is the query plan, you are a DP-300 person. If it is the VM metrics or the network path, AZ-104.

Which should you take first?

• Working DBA moving to Azure: DP-300 directly, no detour. Your SQL Server depth carries; what you need is the Azure SQL specifics, which is exactly what the exam tests.
• General IT admin entering cloud: AZ-104 first. It is the credential recruiters filter on for cloud administrator roles, and it teaches the platform context every specialist exam assumes.
• Aiming at both: AZ-104 then DP-300 is the smoother order. The platform knowledge from AZ-104 (networking, private endpoints, RBAC) shows up inside DP-300's security domain.
• Completely new to Azure data: consider the fundamentals-level DP-900 first; the DP-900 practice test page covers it. It is optional, but it makes DP-300's vocabulary familiar before the stakes go up.

Cost, renewal and how long each takes

Money first: both are associate exams, and Microsoft states associate exams typically cost US$165, priced by country and shown by region when you schedule through Pearson VUE. Both certifications expire after 12 months, and both renew the same way: a free, unproctored, open-book online assessment on Microsoft Learn, available in a six-month window before expiry with unlimited retakes inside it. Neither costs more to maintain than an hour or two a year, so maintenance should not drive the choice.

Preparation time differs by background more than by exam. A production DBA with a few years of SQL Server can usually be DP-300 ready in three to five weeks of evening study, most of it on the Azure-specific pieces: the three flavors of Azure SQL, Entra authentication, and the cloud HA/DR options. AZ-104 from a general IT background tends to take five to eight weeks because no single prior role covers all five domains; someone always has a blind spot, and it is usually networking or Bicep. Whichever you pick, the free official practice assessment on Microsoft Learn is the calibration point: take it once at the start to map your gaps and once at the end to confirm you clear 700 with margin.

Common mistakes when choosing between them

• Taking AZ-104 because it is more popular. Popularity reflects the size of the admin job market, not your job market. A DBA with AZ-104 and no DP-300 still gets screened as a generalist.
• Taking DP-300 as a data engineering credential. It is not one. Pipelines, Spark and warehousing live in the Fabric exams; DP-300 is administration of operational SQL.
• Assuming DP-300 is retired. It is not. Its outline was refreshed effective April 24, 2026; the exams that retired are DP-203 (March 2025) and DP-100 (June 2026).
• Studying both at once. The overlap is too thin to double-dip efficiently. Sequence them and let the AZ-104 platform knowledge feed DP-300's security domain.

Difficulty: deep vs wide

Neither exam is harder in the abstract; they punish different gaps. DP-300 punishes shallow operations experience: developers who write queries all day but have never designed a backup strategy against an RPO target report the HA/DR and tuning scenarios as the wall. AZ-104 punishes narrow experience: storage admins who have never built a Conditional Access policy, or network engineers who have never written Bicep. Read the official study guide for whichever you pick and highlight every objective you cannot explain out loud; that highlighted list is your real syllabus.

Then drill it. Upload your notes or the study guide itself and generate scenario questions weighted to the real domains: build a practice exam from your own material, focus on your highlighted objectives, and finish with the free official practice assessment on Microsoft Learn before you book either exam.

Bottom line

DP-300 vs AZ-104 is a role question, not a ranking question. DP-300 is the only current Microsoft exam aimed squarely at the database administrator job and just got reaffirmed with an April 2026 refresh. AZ-104 is the default cloud administrator credential and the platform on-ramp for every other Azure associate exam. Pick the one that matches the work you want to be doing in a year, and if that answer is honestly both, AZ-104 first, DP-300 second.
