D. DHCP starvation ---------------------------------------- A. Rogue DHCP server attack: Unauthorized DHCP server distributing IP addresses. B. VLAN hopping: Exploiting VLAN vulnerabilities for unauthorized network access. C. STP attack: Disrupting networks through Spanning Tree Protocol manipulation. D. DHCP starvation: Flooding DHCP server to exhaust IP address pool.

D. DHCP starvation "In a DHCP starvation attack, an attacker floods the DHCP server by sending numerous DHCP requests and uses all of the available IP addresses that the DHCP server can issue. As a result, the server cannot issue any more IP addresses, leading to a DoS attack. Because of this issue, valid users cannot obtain or renew their IP addresses; thus, they fail to access their network. An attacker broadcasts DHCP requests with spoofed MAC addresses with the help of tools such as Yersinia, Hyenae, and Gobbler." - Module 08 Page 1246

D. DHCP starvation

D. DHCP starvation Explanation: The scenario describes an attack in which Abel launched a DHCP starvation attack on the client organization's DHCP servers. A DHCP starvation attack is a type of DoS attack that involves flooding the DHCP server with forged DHCP requests in an attempt to lease all available IP addresses in the DHCP scope. This causes the server to run out of available IP addresses, and as a result, legitimate clients are unable to obtain an IP address and connect to the network.
