AWS Certified SysOps Administrator – Associate exam feedback

 

I passed AWS Certified SysOps Administrator exam last week, thus completing the trifecta of AWS associate certifications. I took AWS Solutions Architect associate 3 months back, Developer associate 2 months back which really helped me in increasing my expertise in AWS and my confidence, which is key for this certification.

As expected, Sysops is the hardest one of all 3 associate exams. It tests your in depth knowledge of core services.

You should have an in depth knowledge of VPC, EC2/EBS, IAM, Cloudwatch, ELB/Autoscaling etc., There are many questions where you have to choose multiple answers 2/3/4, so pay attention how many answers need to be selected for the qn.

 

Preparation:

In my opinion, Linux Academy aced this one. The videos are not only in exam pov, also in depth on topic, gives you a good feel of learning. Their final quiz is really upto the exam standard and I highly recommend it.

Cloud Guru is a big letdown . Their Solutions Architect Associate course is top notch, but Sysops course is not updated for the latest syllabus and no efforts in improving the content after concerns raised by multiple users in the discussion forums. Their quizzes are a joke.  You can still refer their Solutions Architect course for this exam preparation due to overlapping of materials.

Pluralsight offers a very detailed course for AWS Sysops, which you can check it out in 10-day free trial. Pluralsight – AWS Sysops

  • Documentation, FAQs, whitepapers

Usually people suggest to read FAQs primarily, but here FAQs have less scope since they don’t cover the topics in depth.

For Cloudwatch, Cloudformation, Opsworks, ELB go through their documentation to understand their different functionalities/features.

Whitepapers will definitely help you in solving questions on AWS audits, responsibility which is crucial to the score.

  • Practice tests

I used Whizlabs quizzes  for practice tests and they’re really hard with lot of mistakes.

But as expected it will give you a good practice before appearing for the exam.

If you pass all their tests and understand which questions you got wrong and where you’re lacking, then you can pass the exam.
