300-715 Question #169: Real Exam Question with Answer & Explanation

Question

An administrator is trying to collect metadata information about the traffic going across the network to gam added visibility into the hosts. This Information will be used to create profiling policies for devices us mg Cisco ISE so that network access policies can be used. What must be done to accomplish this task?

Options

• AConfigure the RADIUS profiling probe within Cisco ISE
• BConfigure NetFlow to be sent to me Cisco ISE appliance.
• CConfigure SNMP to be used with the Cisco ISE appliance
• DConfigure the DHCP probe within Cisco ISE

Explanation

{"question_number": 2, "correct_answer": "D", "explanation": "The DHCP probe is the most appropriate choice for collecting metadata about hosts on the network. When endpoints request an IP address, their DHCP packets contain rich attributes such as hostname, requested IP, OS class hints (via DHCP option 55 and 60), and MAC address. Cisco ISE uses the DHCP probe to intercept or receive these packets (via DHCP helper/relay or SPAN), extract the attributes, and build endpoint profiling policies. This gives ISE visibility into host identity and device type without requiring the host to authenticate first. RADIUS is used for authentication events, NetFlow provides flow-level data rather than host metadata, and SNMP is used for polling device information rather than host traffic metadata.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
