Hi all I am unsure on where to go on this. I have my CompTIA A+, Net+, Sec+ and Linux+ I did my Linux plus last year and I thought they was all stackable for extending the expire dats. What I am wondering is If I do a refresh on my Linux cert would that keep all my certs valid? I was confused when looking around on CompTIA's website about this. Thanks for your time today everyone.
