James, a user, is attempting to access a web page and is unable to. Jennifer, a technician, arrives and pings a computer on the same subnet and receives successful replies. When Jennifer looks at the local computer’s IP address she notices the following IP address: 169.254.15.11.
Given the information in this scenario, which of the following is MOST likely not working properly?
Explanation
Answer: D - DHCP is most likely not working properly given this scenario.
Key Takeaway: Dynamic Host Configuration Protocol has a failover mechanism called APIPA, or Automatic Private IP Addressing. The range of APIPA Addresses is 169.254.0.1 - 169.254.255.254. When Jennifer looked at the local IP address and saw an address that was within that range, she realized that communication with the DHCP service was interrupted for some reason, thereby determining that it may not be working properly. While an argument could potentially be made for one of the other reasons, such as the Network Interface Card, this would more than likely give a different IP address than anything within the range of APIPA. To determine the IP address of the local computer, simply open a command prompt and type in the following command: ipconfig /all.
