Actual exam question from Cisco's 350-701

Question #: 132
Topic #: 1

An administrator configures new authorization policies within Cisco ISE and has difficulty profiling the devices. Attributes for the new Cisco IP phones that are profiled based on the RADIUS authentication are seen; however, the attributes for CDP or DHCP are not. What should the administrator do to address this issue?

A. Configure a service template within the switch to standardize the port configurations so that the correct information is sent to Cisco ISE.
B. Configure the ip dhcp snooping trust command on the DHCP interfaces to get the information to Cisco ISE.
C. Configure the authentication port-control auto feature within Cisco ISE to identify the devices that are trying to connect.
D. Configure the device sensor feature within the switch to send the appropriate protocol information.

I would choose D... Device sensor is a feature of access devices. It allows to collect information about connected endpoints. Mostly, information collected by Device Sensor can come from the following protocols: Cisco Discovery Protocol (CDP) Link Layer Discovery Protocol (LLDP) Dynamic Host Configuration Protocol (DHCP)

Selected Answer: D

D - Device sensor is configured to send DHCP, CDP, and LLDP info to ISE. Since this is a Cisco phone, CDP and DHCP are the relevant here. The CDP, LLDP, and DHCP attributes are grouped together first. Then, the 'device-sensor' command is used to export those groupings to ISE.

Answer is D. Other answer that should have been there, would be that den ip helper-address hasn't been configured to point to ISE, and therefor ISE does not get copies of the dhcp requests of the clients

D - cannot be correct cause device sensor is configured on ISE, NOT on the switch https://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/200292-Configure-Device-Sensor-for-ISE-Profilin.html#anc6 A- service templates can be locally configured on the switch: https://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/200292-Configure-Device-Sensor-for-ISE-Profilin.html#anc6

Selected Answer: D

D is correct, use link provided by andrewj511 and coentror. Answer C is incorrect, as that command needs to be executed on the switch and not on the ISE server
