CCNA SECURITY


Exam Description: The 640-554 “Implementing Cisco IOS Network Security” (IINS) exam is associated with the CCNA Security certification. This 90-minute, 55-65 questions exam tests a candidate’s knowledge of securing Cisco routers and switches and their associated networks. It leads to validated skills for installation, troubleshooting and monitoring of network devices to maintain integrity, confidentiality and availability of data and devices, and develops competency in the technologies that Cisco uses in its security infrastructure. Candidates can prepare for this exam by taking the “Implementing Cisco IOS Network Security” (IINS) course.
