Juniper Networks Certified Specialist, Enterprise Routing and Switching

Juniper · intermediate · 90 minutes

In developmentThis course is still being brought to our full standard. The questions and notes are usable, but they have not yet been checked line by line against the vendor’s own training.

Enterprise routing and switching the Junos way: a committed candidate configuration with commit confirmed as a safety net, VLANs and IRB inter-VLAN routing, trunks and native VLANs, spanning tree with RSTP and MSTP plus BPDU and root protection, and link aggregation with LACP; then OSPF as a link-state protocol with areas and the backbone, the demanding Junos routing policy where import and export direction and explicit redistribution matter, Layer 3 services including VRRP gateway redundancy and equal-cost load balancing, and firewall filters, storm control and port security defending the network.
