Which of the following methods allows multiple VMs to share the same host IP address?

• A. NAT
• B. Bridged networking
• C. Host-only networking
• D. Static IP assignment

Answer: (A)

Network Address Translation (NAT) is a method used to allow multiple virtual machines (VMs) to access external networks while sharing the same host IP address. In NAT configuration, the host machine has its own public IP address, and it acts as a gateway for the VMs. Each VM is assigned a private IP address that is used for internal communication. When a VM wants to communicate with an external network, the host’s IP address is used to represent that traffic on the outside, with the NAT service managing the mappings between the private IP addresses of the VMs and the public IP address of the host. This technique is particularly useful in conserving IP address space, as multiple VMs can use the same public IP address while still being separately identifiable within the host's network. It also provides an additional layer of security since the VMs' internal IP addresses are not directly exposed to the external network. In contrast, bridged networking would give each VM its own unique IP address on the same network as the host, which does not allow for the sharing of a single IP address. Host-only networking isolates the VMs from external networks, allowing only communication between the host and the VMs, thus also not supporting shared external IP utilization. Static
