FAQs about being a Network Administrator
What is the difference between a switch and a router?
A switch connects devices within a local network and uses MAC addresses to forward data to the correct destination. A router connects multiple networks together and directs data between them using IP addresses. Switches operate at Layer 2 of the OSI model, while routers operate at Layer 3.
How do you troubleshoot a network connectivity issue?
To troubleshoot a network connectivity issue, start by checking physical connections and ensuring devices are powered on. Use tools like ping and traceroute to identify where the connection fails. Check configuration settings, review logs, and verify that network devices such as switches and routers are functioning properly.
What is DHCP and why is it important?
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices on a network, reducing manual configuration and preventing address conflicts. It is important because it simplifies network management and ensures devices can communicate efficiently.
