Network Services for Predictability & Reliability
Network Services for Predictability and Reliability explores essential supporting services that enhance network stability, observability, and ease of troubleshooting in production environments. It begins with the Network Time Protocol (NTP), explaining how accurate time synchronization across devices is critical for reliable log correlation, event tracking, and operational consistency. Learners then move into gateway redundancy mechanisms such as HSRP and VRRP, which ensure continuous network availability by providing failover capabilities when primary gateways become unavailable. The course also introduces IP SLA as a proactive monitoring technique that actively tests network reachability and performance, allowing issues to be detected before they impact end users. Overall, it helps engineers understand how these foundational services work together to improve resilience, increase visibility, and reduce response times in real-world network operations.

Keith Bogart
Course Instructor
Keith started his networking career as customer service representative at Cisco Systems in 1996. His desire to learn more soon led him to a position as a Cisco Technical Assistance Center (TAC) engineer on the “Dial-Access” team, and within six months he had obtained his Dial-ISP CCIE. He later became a network consulting engineer and obtained his CCNA certification while teaching the technologies to Cisco employees during his lunch breaks. Keith was the first instructor on Cisco’s TAC Training team, where he taught a wide range of internetworking topics and later developed and taught other courses such as routing protocols, LAN switching, MPLS, 802.1x, and CCNA. After almost 17 years with Cisco, Keith joined a small startup and focused on 802.11 Wi-Fi technologies, during which time he obtained his CWNA certification. He is now very happy to be working as an instructor for Routing & Switching. Keith lives in Raleigh, North Carolina, with his wife, son, and daughter. When he is not teaching Bootcamps, Keith can be found at home with his family, reading, or working in the yard.
