What devices can be used to implement DHCP Snooping?
(Choose two answers)

(A) Hub
(B) Layer 2 switches
(C) Routers
(D) Layer 3 switches
(E) Access Points
(F) End users

B and D are the correct answers.

Layer 2 switches, as well as Layer 3 (multilayer) switches, perform DHCP Snooping. DHCP Snooping must be implemented on a device that performs Layer 2 switching. The DHCP Snooping function needs to examine DHCP messages that flow between devices within the same broadcast domain (VLAN). The fundamental use case for DHCP snooping is to prevent unauthorized (rogue) DHCP servers offering IP addresses to DHCP clients. Rogue DHCP servers are often used in man in the middle or denial of service attacks for malicious purposes.
