Accredited training for the Cisco Certified Support Technician (CCST) Networking certification.
Presentation
In an interconnected world, stable, high-performance network infrastructure underpins every digital activity. Gaps in communication protocol knowledge and poor management of connectivity equipment can limit productivity and expose organisations to significant operational risks.
This Cisco CCST Networking course is an ideal starting point for developing recognised networking expertise. Immersive practical work and assessment quizzes build the operational skills to understand, install and troubleshoot network environments using Cisco quality standards.
By the end of the course, you will be fully prepared to take the CCST Networking 100-150 certification exam. This credential formally validates your ability to work on modern network infrastructure and support essential connectivity services (see the Certification tab for details).
Objectives
By the end of this Cisco CCST Networking course, you will be able to:
- Identify the OSI and TCP/IP models and fundamental network components.
- Understand IPv4 and IPv6 address formats and subnetting concepts.
- Configure and verify connectivity across different endpoints and media types.
- Interpret infrastructure device status and understand routing and switching fundamentals.
- Diagnose network problems using packet analysers and CLI commands.
- Apply network security fundamentals and configure wireless protection.
- Prepare effectively for exam 100-150 to achieve Cisco Certified Support Technician (CCST) Networking certification.
