Which two are primary reasons to use IPv4 private address space? (Choose two.)

IPv4 private address spaces (like 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) are primarily used for two reasons. First, they enable intra-enterprise communication, allowing devices within an organization's private network to communicate with each other without needing globally unique IP addresses. Second, they conserve global address space. By using private addresses internally and translating them to a few public IP addresses at the network edge (via NAT), organizations reduce their demand for scarce public IPv4 addresses. Implementing NAT is a mechanism used with private addresses, not a primary reason for their existence. Connecting applications and managing routing overhead are general network functions, not specific to private address space.
