Static NAT uses the same IP for incoming & outgoing traffic

not Static NAT

Static NAT is not because, Static NAT uses the same IP for imcoming & outgoing traffic. Correct answer is Source NAT & Destination NAT i.e. C & D

A. static NAT and C. destination NAT Explanation: Static NAT: This type of NAT is used to map a public IP address to a private IP address, allowing external clients to access internal resources like webservers. The public IP will always map to the same private IP, ensuring consistent access. Destination NAT: This type of NAT is used to translate the destination IP address of incoming packets to the private IP address of the webservers. This allows traffic directed at a public IP address to be forwarded to the correct internal server. Other options: Hairpin NAT: This is used when internal clients need to access services hosted on the same internal network via their public IP address, which is not relevant here. Source NAT: This is typically used for internal hosts to access external networks, which is not needed since the webservers are not initiating outbound connections.

Static NAT defines a one-to-one mapping from one IP subnet to another IP subnet. The mapping includes destination IP address translation in one direction and source IP address translation in the reverse direction. From the NAT device, the original destination address is the virtual host IP address while the mapped-to address is the real host IP address. So not Static NAT

A. Static NAT D. Source NAT Static NAT is used to provide a consistent, unchanging public IP address for your webservers when accessed from the Internet, allowing inbound connections to them. Source NAT is used for outbound connections initiated by your webservers to external servers, allowing you to translate their private IP addresses to a different public IP address, ensuring that the IP used for incoming web traffic is not the same as the one used for the servers' outbound connections.
