The 640-722 Implementing Cisco Unified Wireless Network Essential (IUWNE) exam assess the knowledge and skills of a candidate in managing Wireless Local Area Networks (WLANs) of size ranging from small to medium. The candidate must be able to effectively install, configure, operate and troubleshoot WLANs in an enterprise. The candidate will require having knowledge on the fundamentals of spread spectrum technology, information on the standards, regulatory bodies and certification relating to wireless technologies, effect of different wireless technologies, networking technologies for WLAN, encryption and authentication methods, principles of WLAN radio frequency, knowledge of frame types and wireless topologies.
Why is this exam required?
The objective of this exam is to assess the competence of a candidate in designing, installing, configuring, monitoring and troubleshooting a Cisco WLAN in and enterprise. Success in the 640-722 IUWNE exam establishes the competency of a professional to support Cisco WLAN based simple wireless network for networking solutions for a small business to a medium sized enterprise. With this knowledge and skill set, a professional can take the following job roles in an enterprise:
- System engineers
- Network administrators
- Network engineers
- Network managers
- Project managers
- Program managers
- Network designers
- Sales and marketing
The associated certification of the 640-722 IUWNE exam is the Cisco Certified Network Associate Wireless (CCNA Wireless) certification. The CCNA Wireless is an associate-level certification that validates the skills and knowledge of a professional in using Cisco network devices to install, configure, execute and maintain WLAN in a small to medium sized enterprise.
The prerequisite for taking up the certification exam is to be certified as a Cisco Certified Entry Networking Technician (CCENT), Cisco Certified Network Associate (CCNA) Routing and Switching, or Cisco Certified Internetwork Expert (CCIE) certification. On the knowledge front, the candidate must have the basic knowledge of computers including Microsoft office, windows navigation and internet usage; deployment of Cisco lifecycle; and regulation environments, standards and certification of relating to wireless.
The 640-722 exam is divided into six domains that are equally important and critical to be understood. Each domain has different weight age in the exam however it is important to fully cover each subject of every domain. Following are the six domains with their percentage in the exam:
- WLAN Fundamentals (20%)
With the widest coverage in the exam content, the candidates need to have a thorough understanding of the fundamentals of wireless local area network (WLAN). This domain includes information on spread spectrum technology, effects of different wireless technologies, wireless regulatory bodies, certifications and standards, wireless networking technologies, wireless topologies, encryption and authentication, frame types, and principles and deployment considerations of WLAN radio frequency (RF).
- Basic Cisco Wireless LAN (17%)
With the knowledge on installing basic wireless LAN, the exam demands the candidates to know Cisco Unified Wireless Network architecture components, installation and configuration of access points, deployment modes, discovery and association of access points, roaming, fundamentals of Radio Resource Management (RRM) and operational verification of basic wireless network.
- Wireless Clients (15%)
This domain requires the candidates to have knowledge on identification of basic configuration of wireless applicants, configuration requirements of client WLAN, and parameters for configuration of AnyConnect 3.0 or above.
- Implement Basic WLAN Security (19%)
This is one of the most important domains for the exam that relates to implementation of Basic WLAN Security. The domain requires the candidates to have the information on the general framework of wireless security and security components, various sources of authentication and authentication methods, configuration of encryption and authentication methods on WLAN and implementation of guest networking through wireless.
- Operate Basic Cisco Wireless Control System (WCS) (17%)
This domain requires the candidates to know key functions of WCS and versions and licensing of navigator, configuration of access points and controllers, navigation through WCS interface, using the maps in WCS, using WCS to check WLAN operations, and generation of WCS reports.
- Conduct Basic WLAN Maintenance and Troubleshooting (12%)
The candidates must also know to conduct maintenance and troubleshoot of WLAN with information on the tools for troubleshoot of WLAN and WCS client, transferring OS images, logs and configuration files between WLC's through the Graphic User Interface (GUI), and know the use and difference I using AP and WLC for managing access methods.
With increased use of wireless network technologies in various organization globally, the demand for specialized professionals in wireless technologies is also on rise. Cisco being one of the most trusted network devices and related technology provider, a Cisco certified professional in the company's wireless technologies will have enormous job opportunities from employers to develop and maintain the reliability, security and cost-effectiveness of the wireless networks of their organizations.
