Correct answer: ASCII.
Why this is the answer
The correct answer is ASCII. WPA2-PSK (Pre-Shared Key) passphrases on Cisco Wireless LAN Controllers (WLCs) are typically configured using ASCII characters. This ensures compatibility and proper interpretation of the passphrase by both the WLC and client devices. Decimal, Unicode, and Base64 are not standard or supported formats for directly entering WPA2-PSK passphrases in the WLC GUI. While data might be represented internally in different formats, the user-facing input for the passphrase is ASCII.
