1) The two functions of the network layer are __________ and _____________
Answer:
b) addressing, routing
Explanation:
The two functions of the network layer are addressing and routing. The network layer identifies a route which is appropriate for data transmission from source to destination and the network layer also appends a header information to the data packet which includes the IP address of both the sender and the receiver.
2) When manually configuring the TCP/IP network addressing information on a computer, which of the following pieces of information is NOT needed?
Answer:
a) The IP address of at least one DHCP server
Explanation:
When manually configuring the TCP/IP network addressing information on a computer, the information required is the IP address of at least one DNS server and the subnet mask. The IP address of the DHCP server is not required. But if you are configuring the TCP/IP network addressing automatically then everything is done by the system.
