CCKM stands for Cisco Centralized Key Management. It is a protocol used in Cisco wireless networks to facilitate the rapid exchange of encryption keys between clients and access points. The main purpose of CCKM is to streamline the process of re-authenticating clients, particularly in environments where mobile users frequently switch between access points.

When a client moves from one access point to another, the re-authentication process can introduce delays. CCKM reduces this delay by allowing the access point to use a centralized key management system to manage and distribute keys efficiently. This centralized approach minimizes the time required for clients to re-establish connections, leading to a more seamless experience for users in environments with high mobility, such as corporate offices or schools.

Other options presented do not accurately reflect CCKM's functionality. For instance, while "Cisco Cloud Key Management" might sound relevant in today's cloud-centric world, it does not pertain specifically to the key exchange mechanics of wireless networks. "Cisco Configurable Key Module" and "Common Channel Key Mechanism" do not exist as recognized terminologies in the context of Cisco wireless solutions, further affirming that Cisco Centralized Key Management is the appropriate term corresponding to CCKM.
