Cisco SD-WAN - Operations Troubleshooting and Best Practices
Denna kurs fokuserar på Cisco Software-Defined WAN (SD-WAN), en overlay-arkitektur som eliminerar de huvudsakliga nackdelarna med traditionella WAN.
Som deltagare lär du dig använda Cisco SD-WAN över alla transportmedia (MPLS, bredband, LTE, VSAT etc) samt utföra felsökning, hantering, policykontroll och applikationssynlighet i hela organisationen.
Kursen täcker produkten Cisco SD-WAN-och innehåller omfattande laborationer för att förstärka den inhämtade kompetensen.
Kursen levereras i samarbete med NterOne.
Målgrupp och förkunskaper
Kursen riktar sig tillö nätverkstekniker och nätverksingenjörer som planerar, implementerar eller administrerar en Cisco SD-WAN-lösning.
Som deltagare förutsätts du ha grundläggande kunskaper i arkitekturen hos ett Wide Area Network (WAN)-nätverk.
För att alltid hålla en hög kvalitet på våra teknikkurser använder vi både engelsk- och svensktalande experter som kursledare.
