DRAG DROP
A user is unable to connect to the Internet. Based on the layered approach to troubleshooting and beginning with the lowest layer, drag each procedure on the left to its proper category on the right.

Correct Answer:

Explanation:
The question asks us to "begin with the lowest layer" so we have to begin with Layer 1: verify physical connection; in this case an Ethernet cable connection. For your information, "verify Ethernet cable connection" means that we check if the type of connection (crossover, straight-through, rollover...) is correct, the RJ45 headers are plugged in, the signal on the cable is acceptable... Next we "verify NIC operation". We do this by simply making a ping to the loopback interface
127.0.0.1. If it works then the NIC card (layer 1, 2) and TCP/IP stack (layer 3) are working
properly.
Verify IP configuration belongs to layer 3. For example, checking if the IP can be assignable for
host, the PC's IP is in the same network with the gateway...
Verifying the URL by typing in your browser some popular websites like google.com,
microsoft.com to assure that the far end server is not down (it sometimes make we think we can't
access to the Internet). We are using a URL so this step belongs to layer 7 of the OSI model.
