Which term refers to intercepting network data, including IPs, MACs, and VLANs?

• A. Data Interception
• B. Arpspoof
• C. VoIP Call Tapping
• D. Session Hijacking

Answer: (A)

Intercepting data in transit across a network means capturing the packets as they move, which reveals header information like IP addresses, MAC addresses, and VLAN tags. This broad action is described as data interception, since it covers eavesdropping on traffic across multiple layers and header fields. In practice, sniffers or network taps collect these details, showing who’s communicating (IP), who’s on the same link (MAC), and how traffic is organized into VLANs. Arpspoof is a specific MITM technique used to position oneself to intercept by spoofing ARP mappings; it’s a method to enable interception, not the act of intercepting traffic itself. VoIP Call Tapping targets voice traffic specifically, not general data across the network. Session Hijacking involves taking over an active session rather than merely listening to data in transit. So the broad term that best fits intercepting network data, including IPs, MACs, and VLANs, is data interception.
