Vikas Naidu –
Very well structured set of questions in each of these sample tests. It was quite similar in difficulty to the questions that I faced in the actual certification exam. Provided a great hand-on experience in how one should go about choosing answers in the multi-choice, as many questions in the actual exam have tricky choices. I would greatly recommend these tests for anyone wishing to take the Docker certification. The recommendation to retake the exams till we achieve 80% consistently was spot on!
Debasish Majumder –
Today I passed my exam. Great course really prepared me for the test.
These sample questions are really good and documented with appropriate information and explanations. These practice exams added value to my knowledge and I would recommend others to use these sample papers as a reference.
I completed the my training and then used these papers to check my readiness for the exam. I like the format of these practice tests and I especially like the feedback.
Nima Ram –
Very helpful, if anything these were harder than the actual exam so by the time I took the exam I felt quite confident and passed easily. My only complaint with these is that some of the questions are poorly worded making them difficult to answer. Anyways I Highly recommend.
Jaggi Keerath –
I got 90% of the questions from this practice sets only. Passed with 92% in the first attempt itself. Thanks, Skillcertpro for this wonderful content and explanation of questions which helped me a lot
Hanney Sunar –
The actual test is very similar to these practice tests. The explanations provided are self-sufficient. I scored 82, 74, 83, 80, 74 in the 5 skillcertpro practice tests . Analyzed them and then attempted Docker actual exam on Monday. I scored 88% in the official exam. This is a must-buy course if you want to pass the exams with flying colors.
Jason Wang –
Just passed the Docker exam on 5/30. This was my second try and I didn’t use the practice exams for the first one. The detail that these questions go into was very helpful for the actual exam. The explanations also helped me fill in any gaps of information that I was missing. I 1000% recommend these!
AM –
There is a few kubernetes topics covered, but overall questions are similar to the real exam.
Remember to study DOMC questions in order not to be confused during the exam.
Albeto H –
Highly recommend this! The structure, complexity, content of the questions are the same as the actual exam. Best part is the explanation! Not only does it explain the correct answers but it also explains what each of the services do in the incorrect options. This then is a great way to not only understand the reasoning behind the correct answer but also learn new information while reading the incorrect options.
Anderson Mattos –
Great question bank. Don’t get discouraged if you feel practice exams are difficult. In my experience, the real exam was easier than the practice exams. However, the higher difficulty just leads to better preparation. This practice exam help me a lot.
I got nearly 50% +straight from these tests and rest of them are almost similar questions.
Mike Harley –
This was very helpful in studying for the exam. I sent it to all my colleagues and friends that were studying for the certificate as well. Thank u.
Alrich Weiss –
Best tests for studying before the exam. Many questions came up almost literally in the real exam. Make sure to practice what you do not understand, it will help you in the exam.
Ernest Medina –
Awesome!!! I cleared the Docker exam recently and certainly this set of question papers was very helpful towards brushing the concepts and digging back to notes to solve the tricky ones – this proved very useful to answer some of those very conceptual scenarios based questions during the actual exam. Thank you for such a wonderfully curated paper…..
Jannie Franci –
Great and exceeded expectations, each practice test is really helpful with wide variety of questions. my confidence is increased to go for the exam. Finally passed.
