The AWS DVA-C02 practice test trains you in developing, testing, deploying, and debugging AWS cloud-based applications.

Why should I take the AWS DVA-C02 exam? 

The AWS Certified Developer - Associate DVA-C02 certification exam is aimed at those professionals that work in a developer role and have at least one year’s hands-on experience in developing, testing, and maintaining applications by using AWS services. Earning this role-based certification will enhance your credibility as an AWS developer by allowing you to validate and demonstrate your skills and knowledge to current and future employers.

 

The AWS DVA-C02 practice test includes two different modes: certification and practice mode. Certification mode allows you to assess your knowledge and discover your weak areas, with practice mode allowing you to focus on the areas that need development.

System Requirements

A practice test is an informal simulation of the actual exam and aims to educate you better in terms of what to expect when you get to the real thing. A MeasureUp practice test includes around 150 questions covering the exam objective domains. In a MeasureUp practice test, there are two specific test-taking modes to prepare students for their certification: Certification Mode and Practice Mode. 

  • The Practice Mode allows you to highly customize your testing environment. You may select how many questions they want to include in their assessment, the maximum time to finish the test, the possibility to randomize the question order, and select how and which questions will be shown in the test. 
  • The Certification Mode simulates the actual testing environment users will encounter when taking a certification exam. They are timed and do not permit users to request the answers and explanations to questions until after the test.

How to use the AWS DVA-C02 Practice Test? 

You can use the AWS DVA-C02 practice test in two different ways: certification and practice mode. The former gives you the possibility to evaluate your knowledge and discover your weak areas, and the latter enables you to focus on these areas, ensuring you spend your time intelligently. We recommend you to first take the AWS DVA-C02 practice test in certification mode. By reviewing the generated report on completing the test, you will get a helpful overview of which areas require further attention. You should next take the test in practice mode in order to develop those areas. Once you are confident you have improved your knowledge in these areas, you can take the test again in certification mode and, on passing twice consecutively with a score of 90%, you know you are exam ready! 

 

Will the questions be the same as the actual exam? 

Although the questions will emulate those of the official exam in terms of style, content, level of difficulty, for reasons of copyright they will not be exactly the same. This will allow you to fully understand the content you are studying so that, no matter how the questions are focused, you can be confident you are covering the same material and that you will have no problem in passing the exam. 

 

AWS DVA-C02 CERTIFICATION EXAM 

What is the AWS DVA-C02 exam? 

The AWS DVA-C02 is a certification exam by AWS aimed at those professionals that work in a developer role, with at least one year’s hands-on experience in developing and maintaining applications by using AWS services, and who want to validate their knowledge of developing, testing, deploying, and debugging AWS cloud-based applications.

 

How can I prepare for the AWS DVA-C02 exam?  

  • Review the AWS DVA-C02 exam objective domains. 
  • Create a study plan for your preparation. 
  • Register for the MeasureUp practice tests. Our practice tests simulate the actual exam in terms of style, format, skill sets, question structure, and level of difficulty, and can be taken either in practice mode or certification mode. 
  • Practice, practice, practice! When you have looked at all the questions available in the MB-260 practice test, checking the correct answers, reviewing the explanations regarding all the different answer options, and consulting the carefully chosen references, it is now time to use the test’s Certification Mode. This is the closest experience you’ll get to the actual exam. And when you pass the Certification Mode twice consecutively with a score of 90% or more, you know you are… Exam ready!

 

How many questions are on the AWS DVA-C02 exam? 

There are 65 questions on the AWS DVA-C02 certification exam. 

 

What are the differences between the AWS DVA-C02 and DAV-C01 exams? 

One of the main differences between the DVA-C02 and DAV-C01 is the inclusion of the latest AWS services and features in the DVA-C02. In the DVA-C02, there are 57 services and features (15 more than on the DVA-C01 exam). This increase is to ensure that AWS developers are up to date with the latest features. Additionally, there has also been a shift in the objective percentage weightings, with a greater emphasis being placed on deployment and management in the DVA-C02 compared with the DVA-C01.

 

Is the AWS DVA-C02 exam worth it?

Generally speaking, AWS certifications are worth getting and can significantly increase your chances of gaining a promotion or pay rise. Also, by gaining this certification, you will demonstrate to employers, both current and future, your dedication and willingness to invest the time, effort, and money to obtain a certification.
