CCST IT Support study guide
CCST IT Support · Work through your exam, one topic at a time.
The Cisco Certified Support Technician (CCST) IT Support credential is an entry-level certification aimed at people preparing for a first job in a help desk, desktop support, or IT service desk role - including students in Networking Academy programs, career changers, and technicians who want a vendor-recognized starting point before pursuing associate-level certifications such as CCNA. It sits alongside Cisco's other CCST tracks and is intended to validate foundational, hands-on support skills rather than deep engineering design work. The CCST IT Support study guide has 5 sections and about 1,612 words.

Know the TCP/IP layers and what lives at each: IP addressing and routing, TCP and UDP ports, DNS name resolution, and the physical link. An IPv4 host needs four things - an address, a subnet mask (what is local), a default gateway (how to leave the subnet), and DNS servers (how to resolve names).

The CIA triad - confidentiality, integrity, availability - frames most questions. Authentication proves identity; authorization decides what that identity may access; auditing records what happened.
