SY0-501 · Question #156
When connected to a secure WAP, which of the following encryption technologies is MOST likely to be configured when connecting to WPA2-PSK?
The correct answer is B. AES. WPA2-PSK (Wi-Fi Protected Access 2 with Pre-Shared Key) uses AES (Advanced Encryption Standard) as its primary encryption algorithm, providing strong 128-bit or 256-bit symmetric encryption for wireless communications.

Why each option
WPA2-PSK (Wi-Fi Protected Access 2 with Pre-Shared Key) uses AES (Advanced Encryption Standard) as its primary encryption algorithm, providing strong 128-bit or 256-bit symmetric encryption for wireless communications.
DES (Data Encryption Standard) is an outdated and weak symmetric encryption algorithm not used in wireless security protocols; WPA2 relies on AES, not DES.
AES (Advanced Encryption Standard) is the mandatory encryption cipher used by WPA2, replacing the weaker TKIP used in WPA. WPA2-PSK specifically uses AES in CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) mode, which provides both data confidentiality and integrity, making it the correct and most likely encryption technology configured in a WPA2-PSK environment.
MD5 is a cryptographic hashing algorithm used for integrity verification, not an encryption technology, and it is not the encryption cipher used by WPA2-PSK.
WEP (Wired Equivalent Privacy) is a deprecated and highly insecure wireless security protocol that predates WPA2 and uses RC4 encryption, not AES, and has been largely abandoned due to serious vulnerabilities.
