Based on the Endpoint information shown, which collectors were used to profile the device as Apple iPad? (Select two.)
A . HTTP User-Agent
B . SNMP
C . DHCP fingerprinting
D . SmartDevice
E . Onguard Agent
Answer: A,C
Explanation:
HTTP User-Agent
In some cases, DHCP fingerprints alone cannot fully classify a device. A common example is the Apple family of smart devices; DHCP fingerprints cannot distinguish between an Apple iPad and an iPhone. In these scenarios, User-Agent strings sent by browsers in the HTTP protocol are useful to further refine classification results.
User-Agent strings are collected from:
* ClearPass Guest
* ClearPass Onboard
* Aruba controller through IF-MAP interface
Note: Collectors are network elements that provide data to profile endpoints.
The following collectors send endpoint attributes to Profile:
* DHCP
DHCP snooping
Span ports
* ClearPass Onboard
* HTTP User-Agent
* MAC OUI C Acquired via various auth mechanisms such as 802.1X, MAC auth, etc.
* ActiveSync plugin
* CPPM OnGuard *SNMP
* Subnet Scanner
* IF-MAP
* Cisco Device Sensor (Radius Accounting)
* MDM
