Be focused on below Details
I wanted to share a quick prep guide based on recent interviews for the Senior Cisco SD-WAN Engineer role. The interview is highly focused on hands-on SD-WAN (Viptela/Catalyst) knowledge, troubleshooting, and BGP, so preparing around these areas will be key.
Key Focus Areas
- SD-WAN Architecture
- Be clear on roles of vManage, vSmart, and vBond
- Understand vEdge vs cEdge (Cisco Catalyst SD-WAN)
- Know what happens if any controller goes down
- Device Onboarding (ZTP)
- Walk through onboarding a branch device step-by-step
- Troubleshoot if device is not appearing in vManage
- Understand role of certificates
- Routing (Very Important BGP)
- BGP in SD-WAN (underlay vs overlay)
- BGP best path selection
- Troubleshooting neighbor issues
- WAN Migration
- MPLS to SD-WAN migration approach
- Ensuring minimal downtime
- Post-migration validation
- Policies
- Control vs Data policies
- Application-Aware Routing (AAR)
- How to verify policies are working
- Troubleshooting (Most Important)
Be ready for real-world scenarios:
- Tunnel not forming
- Traffic not flowing
- Routing issues
- High latency / packet loss
Focus on explaining your step-by-step troubleshooting approach
- Cloud Connectivity
- Basic understanding of AWS/Azure integration
- Cloud OnRamp (high-level is fine)
Final Tip
Be prepared to discuss your real-time hands-on experience in detail especially:
- Deployments you ve worked on
- Issues you ve troubleshot
- Policies you ve configured
- Migrations you ve supported
