Unfortunately your istio Certified Associate (ICA) course is already out of date, as the Linux Foundation have recently updated the certification requirements and istio version to v1.26
Some examples I’ve already come across : some of the commands in the course no longer work and also the labs are all for istio v1.18. Also the course mentions that Ambient Mode is out of scope, but this IS now in scope according to the updated requirements
More info on this update is here Istio Certified Associate (ICA) Program Changes - Linux Foundation - Education
Also note that the IstioOperator has been deprecated and removed since v1.23, so it feels like the “Installation and Configuration” chapter of the course also needs reviewing - see Istio / Istio has deprecated its In-Cluster Operator
Can you advise as to when this course will be updated to cater for the new exam ?
Thanks
