How much time needed after CCNA to apply for such jobs?
Was looking for jobs after I passed CCNA and came across this:
Design and deploy leaf–spine topologies for GPU clusters (InfiniBand or high-speed Ethernet)
Configure and manage switches such as Mellanox SN5600/SN4600, QM9700/QM9790, or equivalent
Build and optimize RoCEv2 / InfiniBand fabrics (PFC, ECN, DCBX, congestion control)
Implement network segmentation and multi-tenancy (VLANs, VRFs, VPCs, SDN overlays)
Integrate BlueField-3 DPUs, SR-IOV vNICs, and networking offload solutions
Monitor fabric health (performance, congestion, drops, routing, credit starvation)
Troubleshoot high-performance AI training pipelines (collectives, all-reduce, RDMA)
Maintain routing and security configurations: BGP (EVPN), OSPF, MLAG/VPC
Manage spine upgrades and firmware lifecycles
Develop automation for network configuration (Ansible, Terraform, GitOps)
