問題1: Which Cisco program for WLAN client vendors helps to ensure that their devices are
interoperable with Cisco WLAN infrastructure?
A. CCX
B. CCMP
C. ASDM
D. WLSE
正解: A
Explanation:
IEEE and industry standards define how a Wi-Fi radio interoperates with a wireless LAN
infrastructure, and the Wi-Fi CERTIFIED seal ensures interoperability. For many organizations that rely
on mobile computers, however, Wi-Fi CERTIFIED is not enough. These organizations need assurance
that their mobile computers will interoperate with a Cisco wireless LAN infrastructure and support
Cisco wireless LAN innovations for enhanced security, mobility, quality of service, and network
management. The Cisco Compatible seal gives organizations the assurance that they seek. A mobile
computer earns the Cisco Compatible seal through a program called Cisco Compatible Extensions, or
CCX. Like the Wi-Fi certification program, CCX: The CCX specification is a superset of that used for Wi-
Fi certification. In fact, a device cannot be certified for CCX unless it, or the Wi-Fi radio inside it, is Wi-
Fi CERTIFIED.
