Interview prep: questions this posting points to

Written from 8 current Platform postings on Cisco's own careers page — not questions Cisco has asked.

  1. Walk me through how you'd debug a packet drop issue on a Nexus switch where traffic matching an ACL rule is being forwarded incorrectly through the CPU packet path instead of being hardware-switched.
    From the posting: “Demonstrated experience with L2/L3/ACL/QOS Packet Forwarding and/or CPU packet path”
  2. You're on-call for the Nexus switch software and a customer reports intermittent packet loss only under high QoS queue pressure in production. Walk me through how you'd triage this and what root cause analysis you'd write afterward.
    From the posting: “Troubleshoot sophisticated issues within the production environment, may serve customers through on-call rotations to identify end user problems, may lead postmortem and write root cause analysis.”
  3. Tell me about a time you identified and debugged a sophisticated issue in production that required root cause analysis. What was the issue, and how did you solve it?
