DP 420 certification training teaches developers to design, implement, query, optimise and maintain globally distributed cloud native applications built on Microsoft Azure Cosmos DB for NoSQL.
Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB
Got a team to train? Logitrain can deliver the DP-420 Azure Cosmos DB course in house at your premises anywhere in Australia, with the same trainer, course material, mock test and official exam as the public courses. It suits teams who want everyone trained together on dates that suit the business.
Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB
The DP-420 course prepares developers to build and run fast, globally distributed applications on Azure Cosmos DB for NoSQL. Across four days of instructor-led, hands-on training you learn to write efficient queries, model and partition data, set indexing policies, provision resources and carry out everyday operations with the SDK.
It suits software developers and cloud developers who already write C#, Java, Python or JavaScript and want to prove their skills with the Microsoft Certified: Azure Cosmos DB Developer Specialty credential. You will design non-relational data models, plan data distribution across regions, integrate Cosmos DB with other Azure services, and optimise and maintain a production solution for cost, performance and security.
This is a specialty-level course, so a working knowledge of Azure and intermediate coding experience help you get the most from it. If you are newer to the platform, build up through our Microsoft Azure courses first.
Logitrain has trained more than 15,000 professionals since 2004, and this course includes the official certification exam fee, so you can sit the exam within three months of finishing. Browse the wider range of Microsoft certification courses to plan your next step.
The Microsoft Certified: Azure Cosmos DB Developer Specialty proves you can design, build and run cloud-native applications on one of Azure’s flagship NoSQL databases. It is a specialty credential that sits above the fundamentals, and it shows employers you can handle data modelling, partitioning, global distribution and performance tuning in real projects.
With Logitrain the official exam fee is included, so you can sit it within three months of finishing. You receive course material in digital format, every course is backed by our price beat guarantee, and you can sit the exam at Logitrain as a local Pearson VUE test centre or online. Train in the classroom in Melbourne, Sydney and Brisbane, or live online in real time from anywhere in Australia.
There are no compulsory prerequisites for this course, but it is set at specialty level, so some background helps.
Microsoft recommends a working knowledge of Azure and the ability to navigate the Azure portal, intermediate coding experience in C#, Java, Python or JavaScript, and the ability to write code that connects to a SQL or NoSQL database. If you are new to Azure, the Azure Fundamentals and Azure Data Fundamentals courses are a better starting point, and you can find both among our Microsoft Azure courses.
Candidates can achieve this certification by passing the following exam.
- DP-420, Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB, Microsoft Certified: Azure Cosmos DB Developer Specialty
You can book and sit the exam within three months of finishing your course. Sit it at any Pearson VUE test centre, or online through Pearson VUE online proctoring from a private space.
Exam format: a maximum of 60 multiple choice and performance based questions, 100 minutes, with a passing score of 700 on a scale of 1 to 1000.
