Describe the role of network services including DHCP and DNS. 2. Use Cisco Packet Tracer to configure a router to perform DHCP services for a LAN. 3. Explain use of IPv4 private addresses with NAT. 4. Compare TCP and UDP protocol operations for efficiency and reliability. 5. Describe the network services and applications for file transfer, web access, email, remote access and instant messaging. 6.
