Explain why NAT is used and describe two benefits of using it in a network.
Model answer
What a good answer should say
- NAT is used to allow devices on an internal network to communicate with external networks while keeping internal addressing separate from external addressing.
- One benefit is that multiple internal devices can share an external IP address, reducing the number of external IP addresses required.
- Another benefit is that the internal addressing scheme is not directly exposed to the external network, so the organisation can use internal addresses without presenting each one externally.
Explanation
Why this works
The answer should link NAT to address translation and then explain why it is useful. Creditworthy benefits include sharing an external IP address among internal devices and separating internal addresses from the addresses used externally.
The explanation should focus on NAT rather than unrelated network features.
