Solid certification guide for hte 210-260 - [will edit my review post exam].
Lots of great CLI and ASDM examples that are very handy for self-study. End chapters have "fill-in-the-blank" memory study tables and a checklist for self-assessment. Most chapters are very thorough and informative.
Will see how I do on the exam next week. Content isn't too challenging. I've got a lot of years in Cisco Security, and I had hoped to learn more. I'll end up with some federal rating when I pass, so good for me. It was a pretty quick read for what it is. I'm planning on doing one more CCNA, before refocusing on my CCIE Enterprise. Good luck.
