Hi Swaroop,
I agree with the recommendations already shared. For administrators, I would focus on Contact Center Administration, Implementation, Telephony Administration, and Reporting & Analytics.
Contact Center Administration gives you the platform foundation, Implementation helps connect the components, Telephony is essential for troubleshooting trunks, sites, phones, carriers, and network issues, and Reporting & Analytics helps you investigate interactions using real data instead of assumptions.
Beyond training, creating small tests in a lab organization and documenting each new issue or expected behavior has helped me a lot. Certifications provide the foundation, but practical troubleshooting is what really develops analytical skills.
I hope this helps.
