Question

How do you defend against DHCP Starvation attack?

A. Enable ARP-Block on the switch
B. Enable DHCP snooping on the switch
C. Configure DHCP-BLOCK to 1 on the switch
D. Install DHCP filters on the switch to block this attack 375

Answer 1

To defend against DHCP Starvation attack, you can enable DHCP snooping, install DHCP filters, and enable ARP-Block on the switch.

Step-by-step explanation:

To defend against DHCP Starvation attack, you can implement several measures:

1. Enable DHCP snooping on the switch: This feature allows the switch to monitor and control DHCP traffic, ensuring that only authorized DHCP servers can assign IP addresses.
2. Install DHCP filters on the switch: These filters can be used to block DHCP Starvation attacks by limiting the number of DHCP requests from a single MAC address.
3. Enable ARP-Block on the switch: This feature prevents unauthorized devices from sending gratuitous ARP requests, which can be used to launch DHCP Starvation attacks.

By implementing these measures, you can significantly mitigate the risk of DHCP Starvation attacks.
