Network Address Translation (NAT) to configure two servers to have the same public IP address. NAT is a technology that allows multiple devices on a private network to share a single public IP address.

Virtual IP

Going with NAT. If the question were about private IP addresses, I'd say VIP. However, the question doesn't mention that the servers need the same private IP address. The underlying technology that allows multiple devices on a private network to share a single public IP address is NAT.

NAT (Network Address Translation) is used to translate private IP addresses to public IP addresses and vice versa, allowing multiple devices on a private network to share a single public IP address. However, it does not allow two servers to have the same public IP address simultaneously. So the correct answer is B.) VIP

At first I thought NAT but after some research, I think it's VIP.

NAT is definitely the answer. To configure two servers to appear to have the same public IP address, the help desk engineer should use Network Address Translation (NAT). More specifically, Port Address Translation (PAT), also known as NAT overload, is commonly used for this purpose.

Network Address Translation (NAT) is a networking technique that allows multiple devices on a private network to share a single public IP address

Answer is B. VIP (Virtual IP) NAT allows multiple devices on a local network to share a single public IP address. However, it does not inherently provide the ability for two servers to have the same public IP address.

In the context of the question, where two servers need to have the same public IP address, NAT (Network Address Translation) would not be the best fit. NAT is typically used to map multiple private IP addresses to a single public IP address (or a few public IP addresses) for internet access, but it doesn't inherently provide a mechanism for two servers to share the same public IP address in a way that allows them to be individually addressable from the outside. On the other hand, a Virtual IP (VIP) address, often used in conjunction with load balancers, allows multiple servers to appear as if they are a single entity with one public IP address. Incoming traffic to the VIP is then distributed to the backend servers based on load balancing rules. This setup is more aligned with the requirement of having two servers share the same public IP address while still being able to individually handle requests.

NAT because its talking about public IP addresses. this is not a load balancing question, its a matter of giving them a PUBLIC ip. if it didnt say public sure i'd go with VIP, but it because it mentions public, im going A.

NAT (Network Address Translation): NAT is commonly used to translate private IP addresses to a single public IP. However, it doesn’t directly address the scenario of multiple servers sharing the same public IP. VIP (Virtual IP): VIPs are often used in load balancers. They allow multiple servers to share a single IP address, distributing incoming traffic among them. This is a suitable choice for achieving the desired outcome.

I'm going with B: VIP because the question is implying the configuration is for servers specifically, not a LAN.

While NAT is commonly used for translating IP addresses for internet access, VIP is the preferred technology when multiple servers need to share the same public IP address for redundancy or load balancing purposes.

key part of the question to focus on here is 'same public IP' so the answer has to be A. IMO.

NAT allows you to change your private IP address & translate it to an alternative public facing address, you can also configure multiple servers to use one public IP address through NAT, when this was invented, it allowed more IP addresses to be able to reach out to the Internet from big cities. VIPs can include NAT services including a one-to-many Network Area Translation (NAT), which may also be referred to as Port Area Translation, is a networking service that allows one static public IP address (the “one”) to be accessed by many private IP addresses (the “many”), allowing communication between multiple devices on different subnets. RFC 1918 was used to create the standards by which networking equipment assigns IP addresses in a private network. A private network can use a single public IP address. The RFC reserves the following ranges of IP addresses that cannot be routed on the Internet: 10.0. 0.0 - 10.255.

Configuring two servers to have the same public IP addresses is typically achieved using: B. VIP (Virtual IP) Virtual IP (VIP) is a method where multiple servers share the same public IP address, and a load balancer or similar device routes traffic to the appropriate server based on load balancing algorithms or other criteria. VIP allows for high availability and scalability, distributing incoming requests across multiple servers to ensure efficient resource utilization and fault tolerance. NAT (Network Address Translation) is not the optimal solution in this context, as it is commonly used for translating private IP addresses to a single public IP address. DNS caching, RFC 1918 (which defines private IP address ranges), and SDWAN (Software-Defined Wide Area Network) are not directly related to the scenario of configuring two servers with the same public IP addresses.
