CompTIA Network+ Exam Review

Category - Networking

In a scenario where two computers have been assigned the same IP address, which of the following could be the result?
  1. Both computers will connect to the network.
  2. Both computers will be able to connect to the local network, but not to the Internet.
  3. Both computers will not be able to connect to the local network or the Internet.
  4. The computer which was first assigned the IP address will be able to connect, the other will not.
Explanation
Answer - D - As soon as the first PC is assigned with an IP address, the address is locked. If a DHCP is used, then the second PC will never get the same IP address. However if the second PC tries to statically assign the same IP, then IP conflict error arises.

Key Takeaway: if a second system tries to manually assign an IP address that is already in use, the error "There is an IP address conflict with another computer on the network” pops up. These problems typically arise when a computer on the network is assigned an automatic/static IP and the other computer is assigned a manual IP. DHCP servers never assign an IP address that is already in use on the network.
