Hoje realizei o exame JN0-643 da Juniper, este exame não é abrangido pelo “Fast track Program” :(. Depois de realizar as formações Advanced Junos Enterprise Routing (AJER) e Advanced Junos Enterprise Switching (AJEX) foi rever as notas e praticar mais a componente de Multicast e QoS.
Pré-Requisitos
É necessário ter a certificação JNCIA-Junos e JNCIS-ENT
Material de Estudo
Como referi anteriormente as formações foram uma base muito importante bem como os materiais disponibilizados. Além dos Labs durante as formações, usei posteriormente o Juniper Olive , Virtual Labs e o JunosSphere.
Junos Software Release
- 12.3
- 12.1 for SRX Series Devices
Treinamento recomendado
Advanced Junos Enterprise Routing (AJER)
Advanced Junos Enterprise Switching (AJEX)
