What are two reasons to implement IPv4 private addressing on a network (CCNA 200-301)
What are two reasons to implement IPv4 private addressing on a network?
(Choose two)
A. To enable internal applications to treat the private IPv4 addresses as unique
B. To facilitate renumbering when merging networks
C. To expand the routing table on the router
D. To provide protection from external denial-of-service attacks
E. To conserve global unique IPv4 addresses
Solution
Correct answer: A. To enable internal applications to treat the private IPv4 addresses as unique and E. To conserve global unique IPv4 addresses.
Explanation:
A. Implementing private IPv4 addresses allows internal applications to treat those addresses as unique, even though they may overlap with other private networks.
E. Private IPv4 addressing conserves the limited pool of globally unique IPv4 addresses, which are a scarce resource.
The other options are not the primary reasons for using private IPv4 addressing:
B. Facilitating renumbering when merging networks is not a direct benefit of private addressing.
C. Private addressing does not expand the routing table on the router.
D. Private addressing does not provide protection from external denial-of-service attacks.
