The Microsoft DP-420 dumps are a popular resource for students and professionals preparing for the Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB certification. This exam tests your knowledge of data modeling, partitioning, consistency, and other key elements of Azure Cosmos DB solutions.
DP-420 is not just about knowing how Cosmos DB works. It's about how you apply that knowledge in real-world cloud-native applications. Candidates need to understand best practices and design strategies. This is why the use of updated and verified dumps is becoming common in preparation.
Cosmos DB Indexing and Partitioning in Microsoft DP-420 Dumps
One of the top searched topics related to this exam is Cosmos DB indexing and partitioning. Many test-takers find this area challenging. Microsoft DP-420 dumps include practice questions focused on how data is partitioned and how indexes affect performance.
Partitioning in Cosmos DB means dividing data into logical units to improve performance and scalability. You need to know how to choose the right partition key. Indexing, on the other hand, impacts how fast queries run. Understanding indexing policies and how to customize them is vital for the exam.
- Learn how to select the correct partition key based on access patterns.
- Understand logical vs. physical partitioning in Cosmos DB.
- Know when to use manual vs. automatic indexing.
- Study how indexing modes (consistent, none) affect performance.
- Practice configuring indexing policies in JSON format.
- Identify how poor partitioning can lead to hot partitions and throttling.
Change Feed in Microsoft DP-420 Dumps
Another hot topic that shows up frequently in Google searches is the Change Feed feature in Cosmos DB. It is also well-covered in Microsoft DP-420 practice questions, especially in scenario-based questions.
Change Feed lets developers track changes to items in real-time. It's useful for building reactive applications and supports real-time analytics, notifications, and stream processing. Knowing how to use Change Feed with Azure Functions or Event Hubs is essential.
