What type of IP address is assigned to a network node when the DHCP server is not available?
The DHCP server, which stands for Dynamic Host Configuration Protocol, assigns IP addresses to each node on the network. This enables the nodes to communicate with each other using network devices such as routers and switches. Any network engineer should be familiar with this. However, when a DHCP server is unavailable, only seasoned network engineers will know that computers can establish an IP address to communicate with other devices on the network. The interviewer wants to establish that you have advanced knowledge of network operations since you are interviewing for a senior role.
"When a DHCP server is not available on the network, a Windows client computer can still assign its own IP address and subnet mask to enable it to communicate with other devices on the network. This IP address is called APIPA, which stands for Automatic Private IP Address, and will be in the range of 169.254.X.X. This operation occurs automatically if the computer cannot locate the DHCP server within a few seconds. You can also initiate APIPA using the command ipconfig/all."
