Question
A mobile administrator is reviewing the following mobile device DHCP logs to ensure the proper mobile settings are applied to managed devices:
```
10,10/18/2021,17:01:05,Assign,192.168.1.10,UserA-MobileDevice,0236FB12CA0B
23,10/19/2021,07:11:19,Assign,192.168.1.23,UserA-MobileDevice,068ADIFAB109
10,10/20/2021,19:22:56,Assign,192.168.1.96,UserA-MobileDevice,0ABC65E81AB0
10,10/21/2021,22:34:15,Assign,192.168.1.33,UserA-MobileDevice,BAC034EF9451
10,10/22/2021,11:55:41,Assign,192.168.1.12,UserA-MobileDevice,0E938663221B
```
Which of the following mobile configuration settings is the mobile administrator verifying?
- A. Service set identifier authentication
- B. Wireless network auto joining
- C. 802.1X with mutual authentication
- D. Association MAC address randomization Correct
Explanation
The same device, UserA-MobileDevice, receives a DHCP lease each day with a different MAC address, which is exactly what MAC address randomization (private Wi-Fi address) produces. SSID authentication, auto-joining and 802.1X mutual authentication are not visible in DHCP lease records, which show only the IP, host name and MAC address.
