@KhuonPhy Yes I have some handy tips for you for both the exam :
1. Revisit all the guided exercises and labs of the courses.
2. Ensure you can independently complete the lab and comp review exercises without looking at the solution and in an estimated time frame with lab gradings as all Pass.
3. Familiarize yourself with official docs and how to take help from them when needed.
4. Use oc explain or oc help command when needed.
5. Read the exam instructions carefully.
6. Do the exam compatibility test in your laptop/desktop well in advance and not on the exam day.
7. Make sure your configurations in the exam are persistent meaning they must survive reboots.
8. Do not give too much time to a single task in exam - if you are struggling in a task, proceed to the next. But if the tasks are connected then it will be a problem.
9. Always verify the work you have done and match with the expected outcomes.
10. EX280 and EX316 are such exams wherein you need to type a lot and write yamls and do a lot of stuffs - so doing this fast and error proof is another advantage to manage the time efficiently.
All the best !!
