Which of the following is an unlikely reason for the ARP process to fail?
A. CEF switching is disabled on the switch
B. The source device and destination device are in different VLANs
C. The VLAN is excluded from the trunk
D. The host is connected to the switch through an IP phone
E. A faulty cable from host to switch or between switches
F. The trunking encapsulation type is inconsistent on the two ends of the link
Would be nice if you specified “select two options”.
