You are troubleshooting network connectivity issues on a Windows workstation. Which command would you use to view the network adapter's MAC address?

ipconfig /all

You need to view detailed IP configuration information on your Windows workstation. In addition to the IP address, subnet mask, and default gateway configuration, you need to see the network card's MAC address and the addresses of the DHCP and DNS servers the workstation is communicating with. Which command would you enter at the command line to see this detailed information? When you see the DNS server address, you realize that this information needs to be updated. Earlier in the day, you implemented a new DNS server with a new IP address. The workstation will update this information in 24 hours. Which command can you enter at the command line to update the DNS server information right away?

ipconfig /all ipconfig /flushdns

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

You are troubleshooting network connectivity issues on a workstation. Which command would you use to request new IP configuration information from a DHCP server?

Sends an ICMP echo request/reply packet to a remote host. Displays current connections and incoming and outgoing connections. A few simple replies to this request from the remote host indicates that a connection exists between sender and receiver. Displays active sessions, ports, sockets, and the local routing table. Performs a continuous connection test when used with the -t option
