b. Use a virtual private network instead of the company LAN.
c. Use DHCP to automatically assign addresses.
d. Use laptops that do not require IP addresses.

Answer 1

Answer:

C. Use DHCP to automatically assign addresses

Explanation:

DHCP (Dynamic Host Configuration Protocol)  is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.   In addition to the IP address, DHCP also assigns the subnet mask, default gateway address, domain name server (DNS) address and other pertinent configuration parameters.

The primary reason DHCP is needed is to simplify the management of IP addresses on networks.  No two hosts can have the same IP address, and configuring them manually will likely lead to errors. Even on small networks manually assigning IP addresses can be confusing, particularly with mobile devices that require IP addresses on a non-permanent basis. Also, most users aren’t technically proficient enough to locate the IP address information on a computer and assign it. Automating this process makes life easier for users and the network administrator.
