Exame JNCIP-ENT JN0-643

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
