In which situation is private IPv4 addressing appropriate for a new (CCNA 200-301)
In which situation is private IPv4 addressing appropriate for a new subnet on the network of an organization?
A. The network has multiple endpoint listeners, and it is desired to limit the number of broadcasts.
B. The ISP requires the new subnet to be advertised to the Internet for web services.
C. There is limited unique address space, and traffic on the new subnet will stay local within the organization.
D. Traffic on the subnet must traverse a site-to-site VPN to an outside organization.
Solution
Correct answer: C. There is limited unique address space, and traffic on the new subnet will stay local within the organization.
There is limited unique address space, and traffic on the new subnet will stay local within the organization.
Private IPv4 addressing is appropriate when an organization has limited unique (public) IP address space and the traffic on the new subnet will remain local within the organization, without the need to be advertised to the internet.
Explanation:
A. Private IPv4 addressing is not appropriate in this case, as the goal is to limit the number of broadcasts, which can be achieved through other network design techniques, such as segmentation and proper subnet mask selection.
B. Private IPv4 addressing is not appropriate in this case, as the new subnet needs to be advertised to the internet for web services, which requires the use of public IP addresses.
C. This is the correct answer. When an organization has limited unique (public) IP address space and the traffic on the new subnet will stay local within the organization, private IPv4 addressing is the appropriate choice.
D. Private IPv4 addressing is not appropriate in this case, as the traffic on the subnet must traverse a site-to-site VPN to an outside organization, which requires the use of public IP addresses.
