Using a systematic troubleshooting approach, a help desk technician suspects a problem at Layer 3 of the OSI model. In gathering information, which two questions are associated with Layer 3?
When troubleshooting a suspected problem at Layer 3 of the OSI model, the help desk technician can ask the following two questions to gather information:
1. Is the device able to reach other devices on the network?
This question helps determine if the device is able to establish Layer 3 connectivity, specifically if it can send packets to and receive packets from other devices in the network. If the device is unable to reach other devices, it indicates a potential issue at Layer 3.
2. Are there any issues with IP addressing or routing?
This question focuses on the two main aspects of Layer 3: IP addressing and routing. It helps identify if there are any problems with how the device is assigned an IP address or if there are any issues with routing packets to their intended destinations. Problems with IP addressing or routing can often cause connectivity issues at Layer 3.
By asking these two questions, the help desk technician can gain insight into whether the problem lies at Layer 3 and begin troubleshooting the specific issues related to IP connectivity and routing.
