Q: What is the operating system on which Traceroute utilizes UDP packets by default? Select all that pertain.
- Linux
- Mac OS
- Windows 10
- Windows 7
Explanation: Traceroute, which runs on Unix-based operating systems like Linux and macOS, will automatically send packets using UDP by default. In these types of computer networks, the traceroute command works by sending UDP packets to the destination with rising Time-to-Live (TTL) values. It then analyzes the ICMP Time Exceeded answers that are received from intermediate routers to determine the path that leads to the destination. The tracers command on Windows operates with ICMP Echo Request messages as its default setting.
