CCNA: Cisco Certified Network Associate — Question 913

What is the primary purpose of private address space?

Answer options

• A. limit the number of nodes reachable via the Internet
• B. simplify the addressing in the network
• C. conserve globally unique address space
• D. reduce network complexity

Correct answer: C

Explanation

The correct answer, C, is accurate because private address space helps to conserve the limited pool of globally unique IP addresses by allowing organizations to use non-routable addresses internally. The other options do not capture the fundamental reason private addresses are utilized; they may address other aspects of network management but do not focus on the conservation of address space.
