Just passed the Azure Cosmos DB exam! Watch out for questions on multi-region write replication - they test your understanding of conflict resolution strategies. Brush up on choosing between strong and eventual consistency models. Big thanks to Pass4Success for their spot-on practice questions that helped me prepare quickly!

The exam covered various consistency levels in Cosmos DB. Be prepared for scenarios where you need to select the appropriate consistency level based on application requirements. Understanding trade-offs between consistency and performance is crucial.

I recently passed the Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB exam with the help of Pass4Success practice questions. The exam covered topics such as designing partitioning for workloads that require multiple partition keys. One question that stood out to me was related to designing a partitioning strategy for a scenario where multiple partition keys were needed. I wasn't completely sure of the answer, but I managed to pass the exam.

Free Microsoft DP-420 Exam Actual Questions

Note: Premium Questions for DP-420 were last updated On Jul. 21, 2024 (see below)

Question #1

You have a container m an Azure Cosmos DB for NoSQL account. The container stores data about families. Data about parents, children, and pets are stored as separate documents.

Each document contains the address of each family. Members of the same family share the same partition key named family Id

You need to update the address for each member of the same family that share the same address. The solution must meet the following requirements:

* Be atomic consistent isolated, and durable (ACID).

* Provide the lowest latency.

What should you do?
