Q: I wanted to extend my certification by retaking my last exam but got the information from Pearson VUE that I’m not allowed to do so because I’ve already finished that. How do I extend my certification?
A: Check Point policy is that you do not retake an exam you have already passed. You either update or upgrade. Ideally, the best course is to take the next higher exam.The one exception is the #156-915.80: Check Point Certified Security Expert Update - R80. You may recertify the R80 CCSE by taking this exam again
