Wireless encryption modes differ in how they authenticate clients:
* WPA/WPA2 PSK (Pre-Shared Key): Uses a passphrase shared by all clients. No external authentication server (like RADIUS or 802.1X) is required. Simple and suitable for home or small networks.
* WPA/WPA2 EAP: Uses 802.1X (Enterprise mode) and requires a centralized authentication server.
Option analysis:
* A.#Correct - Pre-Shared Key does not require 802.1X server
* B.#Incorrect - Requires EAP-based authentication with 802.1X infrastructure Extract from Official MTCNA Course Material - Wireless Security:
"WPA PSK/WPA2 PSK uses a pre-shared password. WPA/WPA2 EAP requires 802.1X authentication with a RADIUS server." Extract from Rene Meneses MTCNA Study Guide - Wireless Encryption:
"To use a simple password for connecting wireless clients, select WPA2-PSK. It does not require server- based authentication." Extract from Terry Combs Notes - Wireless Security Profiles:
"WPA2 PSK = password-based; WPA2 EAP = 802.1X based. Use PSK for fast, simple authentication."
