Kelvin Tran
Kelvin brings a wealth of networking and systems administration knowledge to CBT Nuggets. More recently, he has focused on honing his automation and DevOps skills. His interest in tech was spurred at a young age when he learned how to turn on his family’s Dell OptiPlex 740 that featured a “blazing-fast” Athlon 64 X2 processor. Kelvin believes that instructors should be companions who are right there alongside learners — and pushing them to achieve goals they previously thought were impossible. When he’s not creating training, Kelvin enjoys playing video games, music (he plays violin), and is a self-described casual badminton player.

Cisco
CCNA Cybersecurity
This CCNA Cybersecurity training prepares you for the Understanding Cisco Cybersecurity Operations Fundamentals (200-201 CCNACBR) v1.2 exam (formerly called Cisco CyberOps). With virtual labs and unlimited practice exams included, you’ll gain experience with SIEM, NetFlow, tcpdump, malware analysis, access control models, and incident response workflows based on NIST.SP800‑61. You'll also learn how to detect network, application, and endpoint threats, investigate attacks like DDoS or man‑in‑the‑middle, and apply defense‑in‑depth. This course is deal for entry‑level security analysts or engineers ready to earn their CCNA Cybersecurity certification and launch an SOC career.
Cisco
Cisco CCNP ISE (300-715 SISE)
Network access control is one of the riskiest changes an IT team can make. A misconfigured 802.1X rollout can lock every user off the network, while unmanaged endpoints, guests, and BYOD devices widen the attack surface. This course gives network and security teams a methodical way to deploy Cisco Identity Services Engine (ISE) and enforce identity-based access across wired, wireless, and VPN connections without causing outages or help desk spikes. It is built for Network Engineers and Security Engineers on the CCNP Security track. Learners plan ISE node personas and redundancy, integrate ISE with Active Directory and LDAP, and stage 802.1X in phases on IOS switches and Cisco WLCs. They also cover MAB, IBNS 2.0, and Local and Central WebAuth for devices that can't run 802.1X. Later skills cover TACACS+ device administration, TrustSec micro-segmentation with staged approver workflows, and posture policies so only compliant endpoints get access. For IT Directors and Team Leads, the 94 skills break into focused 45 to 90 minute segments, so you can assign MAB, guest portals, TrustSec, or posture to match current projects. Virtual labs mirror the course topology, and team reporting tracks progress and completion as your team works toward the 300-715 SISE exam. The result is a team that can design, deploy, and support ISE in-house.
Juniper
JN0-105
This JNCIA-Junos (JN0-105) training gives network administrators a working foundation in networking essentials and Junos OS. It covers the CLI and J-Web interfaces, configuration management, the control and forwarding planes, routing fundamentals including IPv4 and IPv6 subnetting, static routes, longest-match routing, and class of service (CoS), and how to build routing policies and firewall filters. Device monitoring, troubleshooting tools, software upgrades, and password recovery round out a course that follows the official exam objectives. For an IT Director running Juniper in the network, this is the documented standard administrators are held to for configuring and maintaining Junos devices. Juniper retired the JN0-105 exam on 5 April 2026 and now offers JN0-106 for the same JNCIA-Junos credential, so check the current objectives before anyone books a seat.
