Question
**6.4-1 Network- and Link-layer addressing: an end-to-end-scenario (1a).** Consider the network shown below. The IP and MAC addresses are shown for hosts A, B, C, and D, as well as for the router's interfaces. Consider an IP datagram being sent from node B to node D. Match the source/destination network- or link-layer address at the location (3) by choosing a value from the pull-down list.

**Diagram Description:**
- The diagram illustrates a network with several hosts (A, B, C, D) and a router.
- Host A: connected at point (1) with IP and MAC addresses not specified in the image.
- Host B: connected to a switch, leading to the router with its MAC address displayed: `68-01-BC-58-AF-24` and IP `128.119.50.107`.
- Host C: IP `128.119.240.52`
- Host D: IP `128.119.240.60`
- Router interfaces indicate IP and MAC addresses: For instance, an interface shows `49-FA-B0-3C-E2-7C` for its MAC address and `128.119.240.1` for its IP.

**Dropdown Options:**
- MAC Addresses:
  - D5-A0-EE-9A-73-D5
  - 49-FA-B0-3C-E2-7C
  - 72-9E-4A-31-9C-42
  - The MAC address of the switch between host B and location (3)
  - 68-01-BC-58-AF-24
- IP Addresses:
  - 128.119.240.116
  - 128.119.240.15
  - 128.119.50.60
  - 128.119.50.107

**Questions:**
1. What is the source MAC address on the frame at point (3)?
2. What is the destination MAC address on the frame at point (3)?
3. What is the source IP address of the datagram at point (3)?
4. What is the destination IP address of the datagram at point (3)?

These dropdowns and questions test understanding of network and link-layer addressing in a specific network scenario.

What is the source MAC address on the frame at point (3)? 2. What is the destination MAC address on the frame at point (3)? 3. What is the source IP address of the datagram at point (3)? 4. What is the destination IP address of the datagram at point (3)? These dropdowns and questions test understanding of network and link-layer addressing in a specific network scenario.
