What term describes the splitting of a probe packet into several smaller packets during transmission?

• A. Packet Fragmentation
• B. Banner Grabbing
• C. TCP Window Size
• D. TTL Field

Answer: (A)

Splitting a probe into smaller packets is known as packet fragmentation. This occurs when a packet is larger than the path’s maximum transmission unit (MTU); the IP layer breaks the data into smaller fragments that can traverse the network and are reassembled at the destination. This behavior is tied to IP headers with fragment offset and the more fragments flag to indicate continued pieces. The other terms refer to different concepts: banner grabbing collects service banners from a host, TCP window size relates to how much data can be sent before waiting for an acknowledgment, and the TTL field controls how many hops a packet can traverse before being discarded. Fragmentation specifically describes dividing a packet into multiple smaller packets.
