DP-420 Exam FAQs for 2026 Candidates
Which certification does the DP-420 exam lead to?
The DP-420 exam is the official Microsoft exam behind the Azure Cosmos DB Developer Specialty (DP-420) certification, validating the skills measured by the Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB credential. It sits at the Professional (Specialty) level of the Microsoft certification program. It also connects to Microsoft Certified: Azure Developer Associate (AZ-204), Microsoft Certified: Azure Solutions Architect Expert (AZ-305), so the knowledge you build here carries over to those tracks as well.
How many questions are on the DP-420 exam, and how much time do I get?
The DP-420 exam contains 40-60 (approx.) questions to be completed within 100-120. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
What score do I need to pass the DP-420 exam, and what does it cost?
The passing score for the DP-420 exam is 700 / 1000, and the official registration fee is $165 USD (may vary by region). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 281 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

For how many RU/s will you be charged when the actual RU/s usage is zero?
A. 4,000
B. 200
C. 10,000
D. 2,000
E. 0
Question 2

B. Create a container for Author and a container for Book. In each Author document, embed bookId for each book by the author. In each Book document embed authorId of each author.
C. Create a container for Author and a container for Book. In each Author document and Book document embed the data from Bookauthorlnk.
D. Create Author, Book, and Bookauthorlnk documents in the same container.
Question 4
You have an Azure Cosmos DB for NoSQL account named account1.
You have an app named App1 that connects to account1 and uses strong consistency for all requests.
You implement the Azure Cosmos DB integrated cache for account1.
You need to ensure that App1 uses the integrated cache.
What should you do?
A. Change the request consistency level to bounded staleness.
B. Change the request consistency level to session.
C. Set MaxIntegratedCacheStaleness to 0.
D. Set the connectivity mode to direct mode over TCP.
Question 5
You have an Azure Cosmos DB Core (SQL) API account named account1 that is configured for automatic failover. The account1 account has a single read-write region in West US and a read region in East US.
You run the following PowerShell command.
Update-AzCosmosDBAccountFailoverPriority -ResourceGroupName `rg1` -Name
`account1` -FailoverPolicy @(`East US`, `West US`)
What is the effect of running the command?
A. The account will be configured for multi-region writes
B. The account will be unavailable to writes during the change
