CCNA Security Final Exam Quiz - Quiz

It’s quite possibly the most important thing you could know about when studying the topic of networking – security is vital for any network that’s passing information and data from one location to another, to make sure it reaches its destination untouched by any outside source. What can you tell us about it in this final exam?
