I decided to go ahead and work toward the Linux+ Certification. After earning my A+ last year, adding another will only help in the long run. Especially since I use Linux on a day-to-day environment, I would be silly not to go and earn the Certification. What I found so far is much different from A+. Not as many resources, like practice tests out there. What I did find so far is that the resources are sketchy at best. I took a practice test a little while ago and one question did not contain a correct answer. Yikes! One good resource I found, Penguin Tutor (penguintutor.com) contains good tutorials and quizzes. That will be one I check out further. No Professor Messer type resources yet, for Linux, like the A+ videos (http://www.k12opensourceclassroom.org/?p=168).
In earning this certification, I feel like I will be a more valuable resource in my job and also look good on the resume. And hopefully we can re-evaluate our current infrastructure and deploy Linux and Linux servers where and when necessary.
