Static NAT Translation

AD

Static NAT is a type of Network Address Translation (NAT) where a static mapping is created between a private IP address and a public IP address. The main purpose of static NAT is to allow hosts on a private network to be accessible from the public network with a globally unique IP address. Here are the correct statements about static NAT:

A. They allow connections to be initiated from the outside: Static NAT mappings are created to allow inbound connections from the public network to the private network. When a connection is initiated from the outside, the destination IP address is translated to the private IP address of the host, allowing the connection to reach its intended destination. Therefore, statement A is true.

B. They require no inside or outside interface markings because addresses are statically defined: Static NAT mappings are defined by an administrator in advance and are statically configured. As a result, no inside or outside interface markings are required because the addresses are already defined. Hence, statement B is true.

C. They can be configured with access lists, to allow two or more connections to be initiated from the outside: Static NAT mappings can be configured with access lists to allow specific types of inbound connections from the public network. This can include allowing two or more connections to be initiated from the outside if needed. Therefore, statement C is also true.

D. They are always present in the NAT table: Static NAT mappings are always present in the NAT table because they are statically defined. Once configured, the mappings remain in the NAT table until they are removed by an administrator. Therefore, statement D is incorrect as it is always present in the NAT table.

In summary, statements A and B are true about static NAT translation, while statement C is also true. Statement D is incorrect as static NAT mappings are not always present in the NAT table.
