Question

What are two advantages of using private IPv4 addressing?

Choose two

A They allow for Internet access from IoT devices.
B They alleviate the shortage of public IPv4 addresses.
C They provide a layer of security from internet threats.
D They supply redundancy in the case of failure.
E They offer Internet connectivity to endpoints on private networks.

Explanation

Private IPv4 addresses can be reused in many different internal networks because they are not publicly routable, which helps conserve the limited pool of public IPv4 addresses. They also add a basic security boundary because hosts using private addresses are not directly reachable from the public internet unless additional mechanisms such as NAT, port forwarding, or other publishing methods are configured.
