Zorluk: KolayNAT and PAT Implementation

A network administrator needs to publish an internal web server to the internet. The server is assigned a fixed private IPv4 address, and the organization requires a permanent, dedicated one-to-one mapping to a single public IPv4 address. Which NAT translation method should the network administrator implement?

  1. Static NATCevap
  2. B
    Port Address Translation (PAT)
  3. C
    Frame Translation NAT
  4. D
    Dynamic NAT

Cevap

Static NAT is the correct solution because it provides a permanent, dedicated one-to-one mapping between a private IP address and a public IP address.
Static NAT configures a fixed, persistent 1-to-1 translation between an inside local private IP address and an inside global public IP address. This static mapping ensures that external users can consistently access the internal web server.

Adım Adım Çözüm

1
Analyze the technical requirements of the scenario
The internal web server requires external internet access using a single dedicated public IP address that never changes.
Publicly accessible services such as web servers require consistent IP addressing so domain name records and external clients can reliably reach them.
2
Match the requirement to the appropriate Network Address Translation type
Static NAT provides a permanent 1:1 translation between an inside local private IP address and an inside global public IP address.
Unlike dynamic methods, Static NAT ensures that incoming traffic sent to the public IP is always routed to the designated internal web server.
