Wpa2-psk

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

PSK authentication verifies wireless clients using a pre-shared secret key.

WPA2-PSK authenticates wireless clients with a pre-shared secret. On a Cisco WLC, it supports simple WLAN configuration through the GUI and corresponds to WPA-Personal authentication. section 21.0 section 21.1.2

Keep these implementation distinctions in view:

  • Configure the WLAN security settings through the WLC GUI when providing client connectivity. section 21.0
  • Select PSK authentication instead of WPA-Enterprise, which requires a RADIUS server and 802.1X/EAP. section 21.1.2
  • Treat WPA2-PSK configuration and verification as a CCNA WLAN task performed in the controller GUI. section 21.0
Configure a RADIUS Server now? [YES][no]: no

The initial WLC wizard distinguishes RADIUS-backed enterprise authentication from the PSK path by asking whether to configure a RADIUS server. section 21.1.2

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Explains configuration scope and authentication contrast, but does not detail handshake internals or CLI commands.
Examples
Uses Cisco WLC GUI configuration and an initial wizard prompt about configuring a RADIUS server.
What it assumes
Builds on WLAN security and architecture fundamentals while focusing on controller-based configuration.
What you can do after
Configure and verify a WLAN using WPA2-PSK through the Cisco WLC GUI.
How it connects
Connects WLANs, WLCs, WPA-Personal, WPA-Enterprise, RADIUS, and 802.1X/EAP.
