A useful Google IT Support roadmap follows the way support work happens: understand the user issue, check hardware and software, inspect operating systems, test networking, review accounts, apply security thinking, and document the result.
Start with the support process: listen, clarify, identify scope, test a theory, fix carefully, verify, document, and escalate when needed.
Review components, peripherals, storage, displays, printers, power, cabling, and physical symptoms. Hardware knowledge helps decide whether software troubleshooting is even the right path.
Study Windows and Linux fundamentals: files, processes, users, permissions, logs, updates, software installation, and basic command-line actions.
Learn TCP/IP, DNS, DHCP, Wi-Fi, routers, switches, VPN awareness, proxies, and simple diagnostic commands. Practice matching symptoms to likely network layers.
Go deeper on common access issues. DNS problems affect names, DHCP problems affect address assignment, wireless problems affect local connectivity, and VPN issues affect access to protected resources.
Review password resets, locked accounts, MFA, groups, file permissions, least privilege, and access requests. Many tickets are access problems disguised as application problems.
Study backups, updates, remote access, provisioning, directory concepts, storage, basic server awareness, and monitoring. Know when an entry-level technician should gather evidence and escalate.
Review malware, phishing, encryption, patching, password managers, MFA, authentication, authorization, and safe handling of user information.
Finish by mixing scenarios. Classify each issue as hardware, software, Windows, Linux, networking, DNS, DHCP, VPN, account, permission, security, documentation, communication, or escalation.
