Cisco CCST Networking Certification FAQs

CCST Networking exam is 50 minutes in duration with approximately 40-50 questions. This is an entry-level networking certification and gateway to CCNA exam. Students have the option of either in-person or online testing.

Cisco Certified Support Technician (CCST) Networking certification prepares you for entry-level roles such as Network Support Technician, Entry-level Help Desk Technician, or IT Support Specialist. You will learn how networks operate, including the devices, media, and protocols that enable network communication.

Develop key skills so you can perform basic troubleshooting, using effective methodologies and help desk best practices. This certification is well-suited for non-technical roles as well such as IT Project Managers. Learn the networking lingo for data center and cloud implementation.
