From the blog as below
..... I passed the 2 CompTIA Linux+ exams, then forwarded these to LPI to get LPIC-1, and then forwarded LPIC-1 to Novell.)
Turns out that earning Novell CLA, also qualifies you for Novell Data Center Technical Specialist (DCTS)! This is one of the specializations for solution providers and system integrators in Novell’s PartnerNet. So by passing the 2 CompTIA Linux+ exams, you qualify for FOUR certifications – Linux+, LPIC-1, Novell CLA, and Novell DCTS...
So CLA is different and is lower than CLP, I guess.
