Intercepts IP addresses, MAC addresses, and VLANs connected to the switch in a network?

• A. Arpspoof
• B. Data Interception
• C. Rogue DHCP Server Attack
• D. Address Resolution Protocol (ARP)

Answer: (B)

Data interception is the act of eavesdropping on network traffic to observe the addresses and segmentation details that devices reveal. When traffic is captured in a network that uses switches, you’re able to see IP addresses and MAC addresses as packets move, and you can also learn the VLAN identifiers carried in the frames. This matches the idea of intercepting the information connected to the switch, including who is on the network and how traffic is segmented. ARPspoof is a technique that can enable interception by placing the attacker in the traffic path, but it’s a method used to achieve data interception, not the broad concept itself. A rogue DHCP server attack focuses on altering IP address assignment and network configuration rather than passively observing traffic. ARP is the protocol that maps IP addresses to MAC addresses, not the act of intercepting data.
