CCIE study scenarios
I work for an ISP for 13 years. I occupied various positions from UNIX expert to Network Engineer (mainly DC technologies).
At the moment, I work as an Infrastructure Architect for contact center solutions dealing with various concerns like network, OS, system virtualization, storage/backup...
I am CCNA, CCNP, CCIP, JNCIA, JNCIS-SEC, VCP and EMCISA certified.
I have now the opportunity to sign a new contract with another ISP as a Core Backbone Network Engineer.
As I wanted to study for CCIE R&S, my question is:
What is the best scenario for me to study:
1) Stay with my current ISP, working 20% of my time on network technologies at work BUT 5min walk from home (so a lot more time to study at home)
2) Sign for the other ISP, working 100% of my time on network technologies at work BUT 1h from home (so less study time)
Thank you for your suggestions, thoughts or experience.
