Tips for Certified Istio Administrator
I have recently cleared Certified Istio Administrator by Tetrate. This is a hands-on exam of two hours which tests your knowledge and skills related to Istio Service Mesh. Here are a few tips which might be handful if you are looking to take the exam.
Time-Constraint
Time is a constraint in the exam; thus, you need to be speedy when you’re taking the exam. The exam consists of approximately 19–24 questions, thus you need to be time savvy.
Documentation Aware
You need to be aware of the documentation well. Most of the tasks are straight forward, thus you need to know where to look for what. Below links are allowed in the exam.
Command Savvy
You need to refer to documentation for configuration, but commands are helpful to quickly check the configuration, validate it, and troubleshooting. It would be good to practice istioctl commands along with creating alias for kubectl command.
Correlation Between Components
It is really necessary to know the relationship between the components which helps when you write configuration files. For example, Virtual Service can be used to configure routing and Destination Rules are used to configure what to do with the actual traffic. Thus, this correlation between components should be known.
Apart from this, there is no percentage or marks provided which is required to clear the exam. So, give your best and try to answer all the questions.
I hope this helps anyone who is planning or has planned to take the exam in the near future.
