Episode 5 — Decode Common Network Ports Protocols and Their Real-World Purposes Quickly
This episode builds the port and protocol recognition skills that help A+ candidates answer exam questions faster and troubleshoot real systems more logically. Instead of memorizing numbers without meaning, you will connect major ports and protocols to the services they support, such as web traffic, name resolution, remote access, file transfer, email delivery, and address assignment. The episode explains why knowing that DNS commonly uses port 53, DHCP uses ports 67 and 68, HTTPS uses 443, RDP uses 3389, and SSH uses 22 helps a technician narrow the problem when a service is unavailable, blocked, or misconfigured. It also shows how ports and protocols support the process of elimination, because a failed webpage, mail problem, or remote session often becomes easier to diagnose once you recognize which service should be listening and what role it plays on the network.
