Week 14

What is a primary benefit of Network Address Translation (NAT) for internal networks?

• Reducing latency for internal network communications

• Enhancing encryption for internal network data

• Improving the security of internal networks

• Increasing the bandwidth available to internal network devices

Choose true statements:

• • Public IP addresses: managed and allocated by a dedicated organization and can be used for direct communication on the Internet

• Public IP addresses: can be used by organizations or individuals randomly on internal networks, but cannot be used for direct communication on the Internet

• Private IP addresses: can be used by organizations or individuals randomly on internal networks, but cannot be used for direct communication on the Internet

• Private IP addresses: managed and allocated by a dedicated organization and can be used for direct communication on the Internet

Which of the following best describes the function of NAT in a typical application scenario?

• NAT maps multiple private addresses to a single public address for outgoing traffic and vice versa for incoming traffic.

• NAT converts IPv4 addresses to IPv6 addresses.

• NAT translates only destination addresses of data packets.

• NAT encrypts data packets for enhanced security.

What is the main characteristic of Static NAT?

• Maps private IP addresses to random public IP addresses

• Maps a private IP address to a fixed public IP address

• Translates only port numbers

• Uses dynamic address pools

How does Dynamic NAT prevent address wastage

• By using fixed public IP addresses for all hosts

• By translating port numbers to conserve IP addresses

• By temporarily assigning public IP addresses from a pool

• By mapping private IP addresses directly to external hosts

What does Dynamic NAT lack compared to NAPT?

• Port number translation

• IP address translation

• Utilization of public IP addresses

• Mapping of internal servers

Which NAT type translates both IP addresses and port numbers to improve public address utilization?

• Static NAT

• Dynamic NAT

• NAPT

• No-PAT

What differentiates Easy IP from NAPT?

• It involves address pools

• It uses interface addresses for NAT

• It does not translate port numbers

• It supports bidirectional communication

What scenario is Easy IP particularly useful for?

• When public IP addresses are fixed

• When public IP addresses are obtained dynamically

• For mapping internal servers

• For static address translation

What is the function of a NAT Server?

• To map multiple internal hosts to a single public IP address

• To map an internal server to the public network

• To translate only port numbers

• To provide dynamic address allocation
