FAQs about being a Network Engineer
What is the difference between a hub, a switch, and a router?
A hub is a basic networking device that broadcasts data to all devices on a network, while a switch sends data only to the specific device it is intended for. A router connects different networks together and directs data between them, often providing internet connectivity.
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, and check configuration settings such as IP addresses and subnet masks. Review logs and replace faulty hardware if necessary.
What is subnetting and why is it important?
Subnetting is the process of dividing a large network into smaller, more manageable sub-networks. It improves network performance and security by reducing broadcast domains and allowing better control over network traffic.
