Which term describes selecting the best path for a packet through the network?

• A. Path determination
• B. Data encapsulation
• C. Address resolution
• D. Frame sequencing

Answer: (A)

The idea being tested is how a packet finds its way from source to destination by choosing the route it should take. Path determination describes the process of selecting the best route for a packet through the network, using routing information and metrics such as hop count, bandwidth, latency, and reliability. Routers consult routing tables and apply algorithms to decide the next hop and the path the packet will follow.

This concept is distinct from data encapsulation, which is adding headers and trailers to the data for transmission; address resolution, which maps a network address to a hardware address like IP to MAC; and frame sequencing, which ensures frames arrive in the correct order. So, selecting the best path is path determination because it focuses on the decision about which route the packet should take across the network.
