You are working as a junior technician for a small consulting firm. You have been tasked with installing a new computer on the network. You have performed this task and connected the computer to the network. To verify network connectivity, you decide to ping the network server. Before this can happen, the new device needs to know the MAC address of the network server so it can match it to the IP address. The computer sends a broadcast message, asking who has the IP address. The network server responds with its MAC address, and now the computer can communicate with the server. Which protocol is being used when sending the broadcast message to match the MAC address to the IP address? HTTP IP ICMP ARP

ARP Address Resolution Protocol (ARP) is used to match a device's IP address to its MAC address. Some network devices, such as switches, will build tables to match MAC addresses with IP addresses in order to always know where to send packets to. When a host wants to send some data, it uses ARP to send a broadcast message out on the network, requesting that the host with a specific IP address respond with its MAC address. When the sending host gets the response, it can then match up the MAC address and IP address.

You are the computer specialist for a small business. Your company server is named FS1 and has an IP address of 10.0.0.2. The hardware in your company server has started to experience intermittent failures, so you transfer the shares on the server to a spare server and take the main server offline. The spare server has an IP address of 10.0.0.3. You edit the existing A record for FS1 on your company's DNS server and redirect the hostname to the spare server's IP address of 10.0.0.3. Afterward, most users are able to access the shares on the spare server by hostname, but several users cannot. Instead, they see an error message indicating that the FS1 server cannot be found. Enter the command you can run from Command Prompt on these workstations that will allow them to access the shares on FS1 without performing a full restart. ipconfig /flushdns

To correct this problem on a Windows computer, run ipconfig /flushdns to delete the local DNS name cache.
