Which two options are the best reasons to use an IPV4 private IP space? (Choose two)
IPv4 private IP space is used within an organization's private network to enable communication between devices without the need for public IP addresses. This private IP space is not routable on the public internet and is reserved for use within private networks.
The two best reasons to use IPv4 private IP space are:
To conserve global address space: Global IPv4 address space is limited, and the number of devices and networks requiring public IP addresses is constantly increasing. By using private IP space, an organization can conserve its allocation of public IPv4 addresses, and use them only where they are needed to communicate with the public internet. This is particularly important in large organizations where hundreds or thousands of devices need to communicate with each other, but only a small number of devices need to communicate with the public internet.
To enable intra-enterprise communication: By using private IP space, organizations can create their own private networks, which are isolated from the public internet. This provides a secure environment for intra-enterprise communication, allowing devices within the network to communicate with each other without exposing them to potential security threats from the public internet. Additionally, private IP space allows an organization to use network addressing schemes that are not available on the public internet, which can make it easier to manage and troubleshoot network issues.
Option B, to implement NAT, is not a reason to use private IP space, but rather a technique used to translate private IP addresses to public IP addresses when communicating with the public internet.
Option C, to connect applications, is not a reason to use private IP space either, as private IP space is used for network addressing, and does not directly connect applications.
Option E, to manage routing overhead, is not a primary reason to use private IP space, but it can be a side benefit. By using private IP space, an organization can reduce the amount of routing information that needs to be exchanged with external networks, which can reduce the overhead on routers and improve network performance. However, this benefit is not as significant as the other reasons listed above.
