Update: Comptia says...
Thank you for your e-mail. The differences in the codes are the JK0-010 is for students and the SY0-101 is for the average candidate not in a student program. The content is the same no difference.
Comptia's websites has two exams listed for security+
CompTIA Security+ E2C Exam: JK0-010
CompTIA Security+ 2002 Exam: SY0-101
I am assume I want to take the sy0-101 if I am going to use this on my mcse:security?
Any one know whats up with this?
