As a Subject Matter Expert in networking you have been contracted and asked by XYZ Corporation to prepare a training session for its networking staff as they prepare to take their CompTIANetwork+ Exam. A particular weakness shown in pretesting reveals the team will need to be able to apply knowledge more effectively to the Open System Interconnection Model. After a short training session the networking staff at XYZ Corporation will need to match the networking technology or device within the proper OSI Layer and explain its allocation.

Consider which layer of the OSI-model is the most appropriate for following functions and devices.

1. Routing: [this goes into the answer key for the instructor] According to the definition, it is one of the most important tasks of the network layer.
2. Telnet-connection for remote use: [this goes into the answer key for the instructor] It works the in the application layer.
3. Ethernet-media repeater: [this goes into the answer key for the instructor] It works in physical layer.
4. Ethernet-switch: [this goes into the answer key for the instructor] It works in Data-link layer of the OSI model.
5. SNMP-based network management agent running in Ethernet switch: [this goes into the answer key for the instructor] This application uses different protocols and is built on the top layer of the OSI model. Details of the lower layers are hidden from network management. So it belongs to the application layer.
6. Error Detection: [this goes into the answer key for the instructor] it works in both data link layer and transfer layer.
7. Fiber cable: [this goes into the answer key for the instructor] is one of the transfer media and used in the physical layer.
