Exam 350-401 topic 1 question 1018 discussion

Chose the Encryption Cipher from the following options: CCMP128(AES) CCMP256 (not available for Personal security type) GCMP128 (not available for Personal security type) GCMP256 (not available for Personal security type)

WPA2 supports only 128-bit encryption keys, while WPA3 supports 128, 192, and 256-bit keys. WPA3-Personal permits the use of CCMP-128 as the minimum encryption algorithm. WPA2 does not support CCMP-256 or the GCMP protocol. However, CCMP-128 is supported by both WPA2 and WPA3. https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#:~:text=The%20new%20standard%20uses%20an%20equivalent%20192%2Dbit%20cryptographic%20strength%20in%20WPA3%2DEnterprise%20mode%5B20%5D%20(AES%2D256%20in%20GCM%20mode%20with%20SHA%2D384%20as%20HMAC)%2C%20and%20still%20mandates%20the%20use%20of%20CCMP%2D128%20(AES%2D128%20in%20CCM%20mode)%20as%20the%20minimum%20encryption%20algorithm%20in%20WPA3%2DPersonal%20mode.%20TKIP%20is%20not%20allowed%20in%20WPA3.

CCMP to CCNP, I smell a rat.

B is correct

Answer B

Answear is C

- Back to B, sorry Cisco docs > open source

Answer is B WPA2+WPA3-Personal Transition Mode with 6 GHz https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/technical-reference/wpa3-dg.html

Answer is C https://www.techtarget.com/searchsecurity/definition/WPA3 WPA3 security uses GCMP-256 encryption instead of 128-bit encryption. Additional info: CCMP256 is a cipher used only for WPA3 Enterprise security, not for WPA3 Personal. CCMP128 is the encryption cipher used for WPA2, not for WPA3.

The answer is correct https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-10/config-guide/b_cg810/wlan_security.html#:~:text=Save%20the%20configuration.-,Configuring%20SAE%20Mixed%20Mode%20(WPA2%2BWPA3)%20(GUI),CCMP128(AES),-CCMP256%20(not%20available

I feel like this one is C, can not confirm
