Exam 200-301 topic 1 question 644 discussion

Keep in mind a CAM table, and a MAC table are the same thing! Therefore, since they are each listed, you can eliminate both as potential answers. One way to remember is that CAM is MAC spelled backward.

A DHCP table is built that includes the source MAC address of a device on an untrusted port and the IP address assigned by the DHCP server to that device. The MAC address and IP address are bound together. Therefore, this table is called the DHCP snooping binding table. Source: CCNAv7: Switching, Routing, and Wireless Essentials, chapter 11.3.2

D is correct

A switch maintains DHCP snooping information in its DHCP snooping binding table. The DHCP snooping binding table is a dynamic database that the switch uses to keep track of DHCP bindings between IP addresses and MAC addresses on the network. When DHCP snooping is enabled on a switch, the switch monitors DHCP traffic between DHCP clients (devices that request IP addresses) and DHCP servers (devices that assign IP addresses). It examines the DHCP packets and extracts information such as the source MAC address, IP address, VLAN, and lease time. The DHCP snooping binding table is then populated with these DHCP bindings, associating MAC addresses with IP addresses and the corresponding VLANs. This information helps the switch in forwarding DHCP traffic correctly to ensure that DHCP clients receive their assigned IP addresses and that unauthorized DHCP servers are blocked.

the cam and mac table are the same thing. there is no such thing as a frame forwarding databse. this leaves only d- binding database

Dynamic Arp Inspection inspects DHCP traffic and tracks the IP address to the mac Address, so if invalid traffic comes with spoofed IP, its dropped because its not in the table. (DHCP snooping has to be enabled first)
