Options

• AVLAN hopping
• BDHCP starvation
• CRogue DHCP server attack
• DSTP attack

• A
  5% (1)
• B
  90% (18)
• C
  5% (1)

Explanation

DHCP Starvation is the correct answer because Abel deliberately flooded the DHCP server with forged requests to exhaust all available IP addresses in the DHCP scope, preventing legitimate users from obtaining IP leases - which is the textbook definition of this attack. VLAN Hopping (A) is incorrect as it involves an attacker gaining access to traffic on multiple VLANs by exploiting switch trunk configurations, not DHCP. Rogue DHCP Server (C) is wrong because that attack involves setting up an unauthorized DHCP server to respond to client requests with false network information (e.g., fake gateway), rather than depleting the address pool. STP Attack (D) is unrelated, as it targets the Spanning Tree Protocol to manipulate network topology and potentially intercept traffic.

Memory Tip: Think of DHCP Starvation like a "seat hog" - the attacker grabs every available "seat" (IP address) at the table, leaving none for legitimate guests. The keyword to watch for in exam questions is "leased all available addresses" or "exhausted the DHCP scope," which directly points to starvation.
