A. B. C. D.


DHCP snooping is a security feature that can be implemented on a network to prevent unauthorized or malicious DHCP servers from providing IP addresses to network devices. DHCP snooping inspects DHCP traffic on the network and builds a binding table that maps the MAC addresses of devices to their assigned IP addresses.

The benefits of DHCP snooping are as follows:

  1. Prevention of DHCP rogue servers: DHCP snooping can prevent the use of unauthorized or rogue DHCP servers that may be set up by attackers to provide IP addresses to devices on the network. DHCP snooping can detect and block rogue DHCP servers by comparing the source IP address and MAC address of DHCP server messages with the DHCP server's binding table.

  2. Preventing static reservation conflicts: DHCP snooping can prevent conflicts that may arise when a network administrator assigns a static IP address that conflicts with a DHCP-assigned IP address. This is because DHCP snooping will not allow a DHCP-assigned IP address to be assigned to another device with a static IP address.

Therefore, the correct answers to the question are C. prevent DHCP rogue server, and A. prevent static reservation. DHCP snooping does not track users' hosts on the network, so option D is incorrect. Additionally, option B is not a valid benefit of DHCP snooping since DHCP reservations are typically used to reserve an IP address for a specific device, so preventing reservation conflicts would be counterproductive.
