This bum ah question

A makes no sense as you could subnet public addresses into an organized hierarchy as well if you had reserved ipv4 addresses. As ipv4 addresses cost money it definitely will reduce the cost of maintaining your network.

C. To segment local IP addresses from the global routing table Private addressing allows organizations to use IP addresses that are not routable on the internet. This means that these private IP addresses are not included in the global routing table, effectively isolating the local network from the public internet. This segmentation can enhance security by preventing external access to internal devices. B. To reduce network maintenance costs Using private addressing can lead to lower costs in network maintenance because organizations can create a large number of private IP addresses without needing to purchase public IP addresses from an Internet Service Provider (ISP). It also allows for the reuse of IP addresses in different internal networks, which simplifies management and can reduce complexity.

A. to subnet addresses in an organized hierarchy Using private addresses allows for subnetting within an organization, providing a structured and organized method of managing IP address allocation in internal networks. C. to segment local IP addresses from the global routing table Private IP addresses are not routed on the public Internet, which segments internal network addresses from the global routing table, helping to conserve public IP addresses and prevent internal IP conflicts with external networks.

According to: https://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/13789-35.html "The obvious advantage of using private address space for the Internet at large is to conserve the globally unique address space. Using private address space also gives you greater flexibility in network design, since you will have more address space available than you could get from the globally unique pool. The primary disadvantage of using private address space is that you have to renumber your IP addresses if you want to connect to the Internet." I would go for AC subnet in organized hierarchy and segment local from global

What are two reasons to deploy private addressing on a network? (Choose two.) A. to subnet addresses in an organized hierarchy B. to reduce network maintenance costs C. to segment local IP addresses from the global routing table - not of importance to us. D. to hide sensitive data from access users within an enterprise - it says "within" meaning users from inside the organization , but we hide sensitive data from users outside the organization so this is false again E. to route protected data securely via an Internet service provider - does not help our asnwers A and B > with 1918 RFC private addressing we can : A. to subnet addresses in an organized hierarchy B. to reduce network maintenance costs - this is not a direct advantage, or main reason why we use IPv4 private addressing not because they are expensive but because addresses are limited in number vs IPv6.

A+C . B > Public IPv4 addresses do cost more but that's not the reason we don't use them, there are very few addresses left . D. Private Addressing is not a valid security measure as specified by the CCNA curriculum E. wrong. Then in my opinion A+C is correct.

Ho ha senso

B & C are most correct

for me its A and D because its referred to ip private address main function

BC is correct

Yesss. B AND C

Two reasons to deploy private addressing on a network are: A. to subnet addresses in an organized hierarchy: Private addressing allows an organization to create a structured and hierarchical network, making it easier to manage and allocate IP addresses efficiently within the internal network. C. to segment local IP addresses from the global routing table: Private addressing, such as the use of private IP address ranges (e.g., 192.168.x.x or 10.x.x.x), helps isolate internal network traffic from the global internet. This segmentation reduces the chances of IP address conflicts and helps maintain internal network privacy. Options B, D, and E do not directly relate to the deployment of private addressing for organizational networks. These options may have relevance in other network security or privacy contexts but are not specific reasons for deploying private addressing within an organization's internal network.

trash question

Correct B and C. We think of the logic of IPv6 where public addresses (global unicast) have no cost to be used and we can create hierarchies of subnets with only public addresses. The question does not say which version of the IP, so we could use IPv6 for hierarchy with subnets of public addresses, but it would have a whole migration to IPv6 which could be unfeasible. In this case the letters "A" and "B" would not be the reasons for using private addresses, if this were the case with IPv6 referring to the cost. Now even with IPv6 having public addresses at no cost, we need to use a private address (unique-local unicast) in cases of confidentiality (security) of sensitive user information on an internal network, against external threats from the Internet in conjunction with a firewall, as security is always a determining factor for using a Unique Local, or even a range of private IPv4 addresses. However, it lacked information about the external network, leaving D half incorrect. (he follows...)

The answer to the question "What are two reasons to deploy private addressing on a network? (Choose two.)" is: A. to subnet addresses in an organized hierarchy D. to hide sensitive data from access users within an enterprise Private addressing is the use of IP addresses that are not globally routable over the Internet . The two common reasons for deploying private addressing on a network are to subnet addresses in an organized hierarchy and to hide sensitive data from access users within an enterprise . Using private addressing allows for efficient use of available IP address space and provides a level of security by keeping private IP addresses hidden from public view.
