350-701 Practice Question: Cisco ISE is performing profiling on a network
Cisco ISE is performing profiling on a network. It receives a DHCP request from a device with vendor class identifier 'MSFT 5.0' and an HTTP user-agent 'Mozilla/5.0 (Windows NT 10.0)'. Which probes are most likely used to collect this information?
⚠ Common exam trap
Cisco often tests the specific mapping of probe to data source, and the trap here is confusing the Device Sensor probe (which collects data via RADIUS accounting or syslog) with the DHCP or HTTP probes that directly capture packet-level information.

Correct answer & explanation
✓
DHCP probe and HTTP probe
The DHCP probe captures DHCP packets, including the vendor class identifier (option 60) which reveals the device type (e.g., 'MSFT 5.0' for Windows). The HTTP probe intercepts HTTP traffic and parses the User-Agent header (e.g., 'Mozilla/5.0 (Windows NT 10.0)') to identify the operating system and browser. Together, these two probes collect the exact information described in the question.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Device Sensor and SNMP probe
Why it's wrong here
Neither captures DHCP vendor class or HTTP user-agent.
- ✓
DHCP probe and HTTP probe
Why this is correct
Correct. DHCP probe captures DHCP options; HTTP probe captures HTTP headers.
- ✗
HTTP probe and Device Sensor
Why it's wrong here
Device Sensor can provide endpoint OS info, but DHCP probe is needed for vendor class ID.
- ✗
DHCP probe and SNMP probe
Why it's wrong here
SNMP probe queries network devices for MAC OUI, not user-agent.
