Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 236

Which two probes provide IP-to-MAC address binding information to the ARP cache in Cisco ISE? (Choose two.)

Answer options

• A. HTTP
• B. RADIUS
• C. DHCP
• D. DNS
• E. NetFlow

Correct answer: B, C

Explanation

The correct answers are B (RADIUS) and C (DHCP) because both protocols actively provide information that helps build the ARP cache by associating IP addresses with their corresponding MAC addresses. Options A (HTTP), D (DNS), and E (NetFlow) do not directly contribute to IP-to-MAC address binding in the ARP cache.
