FAQs
Question: What is the primary function of Network Address Translation? Answer: The primary function of NAT is to translate private IP addresses to a public IP address, allowing devices on a local network to communicate with external networks.
Question: How does NAT improve network security? Answer: NAT enhances network security by hiding internal IP addresses from external networks, making it harder for potential attackers to target specific devices.

Q. How does NAT affect the use of IPsec?
A.
It has no effect on IPsec
B.
It can break IPsec connections
C.
It enhances IPsec security
D.
It simplifies IPsec configuration
Solution
NAT can break IPsec connections because it modifies packet headers, which can interfere with the integrity checks performed by IPsec.
Correct Answer:
B
— It can break IPsec connections
B.
It can complicate certain protocols that require end-to-end connectivity
C.
It enhances security
D.
It allows for IP address conservation
Solution
The main disadvantage of NAT is that it can complicate protocols that require end-to-end connectivity, such as VoIP and some peer-to-peer applications.
Correct Answer:
B
— It can complicate certain protocols that require end-to-end connectivity
Q. What is the primary purpose of Network Address Translation (NAT)?
A.
To provide a unique IP address to every device on the internet
B.
To allow multiple devices on a local network to share a single public IP address
C.
To encrypt data transmitted over the network
D.
To increase the speed of data transmission
Solution
NAT allows multiple devices on a local network to share a single public IP address, which helps conserve the limited number of available public IP addresses.
Correct Answer:
B
— To allow multiple devices on a local network to share a single public IP address
Q. Which type of NAT maps a single public IP address to multiple private IP addresses?
A.
Static NAT
B.
Dynamic NAT
C.
Port Address Translation (PAT)
D.
NAT overload
Solution
Port Address Translation (PAT), also known as NAT overload, allows multiple devices on a local network to be mapped to a single public IP address by using different port numbers.
Correct Answer:
C
— Port Address Translation (PAT)
