Exam Description
The 640-721 Implementing Cisco Unified Wireless Network Essential (IUWNE) exam is the exam associated with the CCNA Wireless certification. This exam tests a candidate's knowledge of installing, configuring, operating, and troubleshooting small to medium-size WLANs. Candidates can prepare for this exam by taking the Implementing Cisco Unified Wireless Network Essential (IUWNE) course.
Exam Topics
The following information provides general guidelines for the content likely to be included on the Implementing Cisco Unified Wireless Networking Essentials (IUWNE) exam. However, other related topics may also appear on any specific delivery of the exam.
