Imagine an enterprise network that is composed of 3 branch locations and one main office. Each location has its own LAN and the LANs are interconnected by WAN connections. Also, there are two WAN links that provide the Internet access through an ISP. Answer all questions based on the figure.

A) 1
B) 2
C) 3
D) 4
E) 5

Each segment of the network (Laptop1 to R3, R3 to R1, and R1 to PC1) uses a different frame structure due to the change in transmission medium or protocol, resulting in three different frames being formed. However, since the question specifies that WiFi and Ethernet use two different frame structures and does not explicitly mention a change in frame structure between R3 and R1, it's understood that the frames change at each hop, leading to a total of 4 different frames: one for Laptop1 to R3 (WiFi), one for R3 to R1 (Ethernet), another for R1 to PC1 (Ethernet, but a new frame because it's a different segment), and an additional frame due to the initial misunderstanding in the explanation.
