1. While troubleshooting a network connection problem for a coworker, you discover the
computer is querying a nonexistent DNS server. What command-line utility can you
use to assign the correct DNS server IP address? Is DNS using UDP or TCP?
To assign the correct DNS server IP address, you can use the command-line utility `ipconfig` on a Windows machine or `ifconfig` on a Unix/Linux machine. The specific command would vary depending on the operating system you are using.
DNS primarily uses UDP (User Datagram Protocol) for its query and response messages. However, it can also use TCP (Transmission Control Protocol) for certain situations like large responses or zone transfers.
To assign the correct DNS server IP address, you can use the "nslookup" command-line utility.
DNS primarily uses the User Datagram Protocol (UDP) for communications. However, if the response from the DNS server exceeds the maximum UDP packet size, it will use the Transmission Control Protocol (TCP) instead.
