As part of the security protocol for your network design, you have designated that option 82 is
enabled for DHCP snooping. When option 82 is enabled, which information will be added to the
DHCP request?
A.
switch MAC address and VLAN, module, and port
B.
remote ID and circuit ID
C.
switch IP address and VLAN, module, and port
D.
switch MAC address and switch IP address
Answer B is correct.
Option 82 was designed to allow a DHCP Relay Agent to insert circuit-specific information into a request that is being forwarded to a DHCP server. This option works by setting two sub-options: Circuit ID. Remote ID.
