A network administrator has set up a small office with a single public IP address. They want to host a web server and an email server internally, but they only have one public IP. Which solution would allow both services to be accessible from the internet?

Disable NAT to allow direct public access

Configure DNS to point both domains to the same IP

Configure port forwarding for both services on the same public IP

Use DHCP reservations to assign public IPs to servers

What is the primary purpose of Network Address Translation (NAT)?

To filter traffic based on port numbers

To encrypt data transmitted over a network

To translate private IP addresses to public IP addresses for internet communication

To resolve domain names to IP addresses

A network technician is explaining to a junior admin why a web server uses TCP port 80 for HTTP traffic. Which characteristic of TCP makes it the appropriate transport protocol for HTTP?

TCP is faster than UDP because it does not check for errors

TCP uses broadcast to send data to all devices on the network

TCP provides reliable, connection-oriented delivery with error checking

TCP is connectionless and does not require a handshake
