The correct answer is C. LLDP E. CDP. Cisco ISE Device Sensor on the access switch collects endpoint attributes and sends them to ISE via RADIUS. To populate the 'system-description' attribute, LLDP (C) must be enabled on the switch - LLDP TLVs include the System Description field. To populate the 'platform-type'…
Question
An engineer must use Cisco ISE profiler services to provide network access to Cisco IP phones that cannot support 802.1X. Cisco ISE is configured to use the access switch device sensor information system-description and platform-type to profile Cisco IP phones and allow access. Which two protocols must be configured on the switch to complete the configuration? (Choose two.)

Explanation
Cisco ISE Device Sensor on the access switch collects endpoint attributes and sends them to ISE via RADIUS. To populate the 'system-description' attribute, LLDP (C) must be enabled on the switch - LLDP TLVs include the System Description field. To populate the 'platform-type' attribute, CDP (E) must be enabled - CDP carries the platform string that ISE uses to identify Cisco IP phones. SNMP (A) is used for a different profiling probe (SNMP Query/Trap), not Device Sensor. EAPOL (B) is the EAP over LAN encapsulation used in 802.1X, which these phones cannot support. STP (D) is a Layer 2 loop-prevention protocol unrelated to profiling.
