A Rede Ficou Lenta e Ninguém Queria Resolver: Cenário Real CCNP ENARSI

The company's network suddenly slowed down, the finance department stopped issuing invoices, and nobody wanted to take responsibility. Ever been through this? In this video, André Steciuk shows a real-world troubleshooting scenario step-by-step. Instead of guessing the problem, we apply a methodology: we rule out physical and link layer faults using interface commands, check MTU and packet fragmentation with ping tests, until we find the real culprit: an incorrectly configured policy-map on the Core Switch limiting server traffic. Learn how to analyze bottlenecks, use the right commands, and solve real problems that are tested on the CCNP ENARSI exam and encountered in the job market.
