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.
