Question:
Which two statements accurately describe an advantage or a disadvantage when deploying NAT for IPv4 in a network? (Choose two.)

• NAT adds authentication capability to IPv4.
• NAT introduces problems for some applications that require end-to-end connectivity.
• NAT will impact negatively on switch performance.
• NAT provides a solution to slow down the IPv4 address depletion.
• NAT improves packet handling.
• NAT causes routing tables to include more information.

Explanation: Network Address Translation (NAT) is a technology that is implemented within IPv4 networks. One application of NAT is to use private IP addresses inside a network and use NAT to share a few public IP addresses for many internal hosts. In this way it provides a solution to slow down the IPv4 address depletion. However, since NAT hides the actual IP addresses that are used by end devices, it may cause problems for some applications that require end-to-end connectivity.
