the question is indeed strange. in CCNA courser it was mentioned several time that NAT is not considered as a security means. So, i would answer like - the goal of using IPv4 private range is to optimize the network address usage
Yes but thanks to private IPs, it is possible to create networks that are "disconnected" from the Internet and therefore have protection.
It's the fact that NAT brings security because private IPs can go out on the internet that is false
The point Niko was making is that Cisco explicitly said NAT is not meant to be a security feature thus contradicting this answer and the logical separation it creates from the public network.
A. provides an added level of protection against Internet exposure --> the secure problem not depend if the network is private or public but the danger is the people that works inside the companies.
The goal achieved by the implementation of private IPv4 addressing on a network is:
A. provides an added level of protection against Internet exposure.
Private IPv4 addresses are reserved for use within private networks, and they are not routable on the Internet. By using private IPv4 addresses, organizations can create their own internal networks that are isolated from the public Internet, providing an added level of protection against external attacks and Internet exposure.
B cannot be the answer because even if I have a private enviroment I can still have a lots of private networks, By defualt we are using just a Default Route for going through Internet, if we have huge companies to be administrated maybe we can talk about BGP.
Basically I can still have a lot of different Networks an example is a Data Center lots of devices in different private networks
private address "allows communicating across public network boundaries"??? Stop smoking funny stuff bruuh!
