Port Address Translation (PAT)

Correct Answer: Implement Port Address Translation (PAT)

The best solution for this situation is to Implement Port Address Translation (PAT). This is because, PAT allows multiple devices on a local area network (LAN) to be mapped to a single public IP address, which makes it possible for multiple devices to access the internet concurrently. On the other hand, Implementing Static NAT or Dynamic NAT is not ideal as these technologies only map a single internal IP address to a single external IP address and would therefore not support multiple devices concurrently. Enabling DHCP for IP allocation is also incorrect because, while DHCP assigns unique IP addresses to devices on a network, it does not solve the problem of having a single public IP address.

Correct Answer: Set up port forwarding to the web server

The best way to make a web server that is behind a PAT (Port Address Translation) setup accessible from the internet is by setting up port forwarding to the web server. Port forwarding is used to direct incoming traffic from the PAT device (often a router) to the correct internal device on the network, based on the port number. This would allow external requests to access the web server on the necessary port. The other answers are inaccurate. Disabling PAT on the router, while it would provide direct internet access, would eliminate the benefits of PAT, such as conserving public IP addresses and providing a layer of security. Placing the web server outside the network would expose the server to potential security risks and would likely be impractical for many organizations. Assigning a static public IP to the web server might seem like a solution, but with PAT in place, this address would not be directly reachable from outside the network without additional configuration such as port forwarding.

Correct Answer: Configure Port Forwarding

To ensure that traffic coming to a specific port is forwarded to the correct internal server, the network administrator should configure 'Port Forwarding'. This function allows external devices to connect to a specific computer or service within a private local-area network (LAN). It works by redirecting a communication port from one IP address to another. The other options are incorrect because they do not directly deal with the forwarding of traffic to a specific internal server: - 'Adjusting MTU Size' refers to changing the maximum transmission unit on a network interface, however this will not help to direct traffic to a specific internal server. - 'Switching from PAT (Port Address Translation) to NAT (Network Address Translation)' does not ensure traffic is forwarded to the right server. NAT translates one IP address to another, while PAT adds port numbers to the translation for even more hosts to share one IP address. Neither directly control the flow of traffic to specific internal servers. - 'Disable PAT': PAT is a form of NAT where multiple internal hosts can share a single external IP. Disabling PAT may disrupt network operations and does not address the issue of routing traffic to an appropriate internal server.
