Comparing AWS, Azure and Redhat exams

In last couple of years I’ve given certification exams of multiple cloud providers. While AWS and Azure exams are more theoretical and based on multiple choice questions. Redhat Openstack is practical lab exam. In this article I’ll be discussing the pros and cons of the different exam patterns.

AWS

Passed AWS CSA – Associate and Professional

Pros:-

  • You can refer to any question any time you want during the exam.
  • Exam tests you on a wide range of topic.
  • Even if you have made mistakes in the beginning you can recover by reviewing the questions later.
  • No datasheet type questions like “How much RAM does C3.Xlarge offers?”
  • You get 1 Year free tier which is great to learn about AWS.

Cons:-

  • Exams are expensive in comparison to Microsoft Azure (at least in India)
  • In many question it just tests your reading speed.
  • No version, so you don’t know if you should answer as per recent announcement or old method available.

Azure

Passed Architecting Microsoft Azure Solutions.

Pros:-

  • Azure exams are not very expensive in comparison to AWS or Red Hat.
  • Exam tests you on a wide range of topic.
  • Even if you have made mistakes in the beginning you can recover by solving correctly other answers in later sections.

Cons:-

  • No version, so you don’t know if you should answer as per recent announcement or old method available.
  • It’s a race against time.
  • The most insane thing I found in the exam is that with each case study you get 5 to 6 questions. But, for about 2 to 3 questions in that case study you can’t refer back to case study. I don’t understand why Microsoft expects you to remember the whole 2 page case study.
  • 30 days free tier is too less to know about azure.

Update:- Azure is now(Oct-17) offering 12 months free trial.

Redhat Openstack

Passed  RHCSA in Redhat Openstack

Pros:-

  • The difficulty level of the exam is medium.
  • You generally get questions on tasks which you will be doing in real life.
  • You get only 15-20 questions (tasks) and even if someone knows those questions beforehand he will have to do the tasks practically to pass the exam. So even if anyone has dumps, they are useless.
  • It has versioning so you know you have to answer as per Redhat Openstack version 6 or 8.
  • Can play with Redhat Openstack by installing it in your desktop or laptop. Good Learning!

Cons:-

  • Exams are expensive in comparison to Microsoft Azure.
  • If you have made a mistake at the beginning or in the middle of exam chances are you will mess up the whole exam or waste lot of time correcting it.
  • If your machine doesn’t work properly you may lose time. But generally examiners take care of this.

In the end, I’d like to say that professional exams should not be like your college entrance exams where they mostly test your reading speeds and cramming abilities. But it’s OK for them as the undergrad and grad have limited practical experience.

Professional exams should be more practical, that makes you sure that if a person has cleared the exam, he definitely know how to do that stuff in real life.

If you want to know how to prepare for these exams refer my post for AWS , Azure and Redhat Openstack .
